ANNEX 1

RESOLUTION MSC.168(79) (adopted on 9 December 2004)

STANDARDS AND CRITERIA FOR SIDE STRUCTURES OF BULK CARRIERS OF SINGLE-SIDE SKIN CONSTRUCTION

THE MARITIME SAFETY COMMITTEE, RECALLING Article 28(b) of the Convention on the International Maritime Organization concerning the functions of the Committee, RECALLING ALSO SOLAS chapter XII on Additional safety measures for bulk carriers, which the 1997 SOLAS Conference adopted with the aim of enhancing the safety of ships carrying solid bulk cargoes, RECALLING FURTHER that, having recognized the need to further improve the safety of bulk carriers in all aspects of their design, construction, equipment and operation, it examined the results of various formal safety assessment (FSA) studies on bulk carrier safety,

RECOGNIZING that banning of alternate hold loading of heavy cargoes in full load condition for bulk carriers of single-side skin construction not meeting appropriate side structural strength requirements would contribute to improving the safety of these ships by reduction of shear forces and bending moments,

NOTING resolution MSC.170(79) by which it adopted, inter alia, the revised chapter XII of the 1974 SOLAS Convention, in particular regulation XII/14 � Restrictions from sailing with any hold empty, where reference is made to mandatory standards and criteria which a bulk carrier has to comply with in order to avoid the above-mentioned restrictions, ACKNOWLEDGING that the International Association of Classification Societies (IACS) has issued the following relevant Unified Requirements:

S12 Rev.2.1 - Side structure in single side skin bulk carriers; and

S31 - Renewal criteria for side shell frames in single side skin bulk carriers not built in accordance with UR S12 Rev.1 or subsequent revisions,

CONSIDERING that the above IACS Unified Requirements embody respectively the standards and criteria necessary to ascertain whether regulation XII/14 of the Convention should apply to a particular bulk carrier, and, therefore, should form the basis of the said standards and criteria,

HAVING CONSIDERED the recommendation made by the Sub-Committee on Ship Design and Equipment at its forty-seventh session, 1. ADOPTS, for the purposes of the application of regulation XII/14 of the Convention:

MSC 79/23/Add.1 ANNEX 1 Page 2


.1 the Standards for side structures in single-side skin bulk carriers, set out in

Annex 1 to the present resolution; and

.2 the Renewal criteria for side shell frames and brackets in single-side skin bulk carriers not built in accordance with the Standards for side structures in single-side skin bulk carriers, set out in Annex 2 to the present resolution;

2. INVITES Contracting Governments to the Convention to note that the annexed Standards and Renewal criteria will take effect on 1 July 2006 upon the entry into force of the revised chapter XII of the Convention; 3. REQUESTS the Secretary-General to transmit certified copies of this resolution and the text of the annexed Standards and Renewal criteria to all Contracting Governments to the Convention; 4. FURTHER REQUESTS the Secretary-General to transmit certified copies of this resolution and the text of the annexed Standards and Renewal criteria to all Members of the Organization which are not Contracting Governments to the Convention.

ANNEX 2

RENEWAL CRITERIA FOR SIDE SHELL FRAMES AND BRACKETS IN SINGLE-SIDE SKIN BULK CARRIERS NOT BUILT IN ACCORDANCE WITH THE STANDARDS FOR SIDE STRUCTURES IN SINGLE-SIDE SKIN BULK CARRIERS

1 Application and definitions For the purpose of SOLAS regulation XII/14, these requirements apply to the side shell frames and brackets of cargo holds in single-side skin bulk carriers, which were not built in accordance with annex 1, but shall achieve an equivalent level of safety for not being subject to restrictions when sailing with any hold empty. These requirements define steel renewal criteria or other measures to be taken for the webs and flanges of side shell frames and brackets as per paragraph 2. Reinforcing measures of side frames are also defined as per paragraph 2.3. Finite element or other numerical analysis or direct calculation procedures cannot be used as an alternative to compliance with the requirements of this annex, except in cases of unusual side structure arrangements or framing to which the requirements of this annex cannot be directly applied. Assessment of compliance with these requirements is to be carried out by the date on which the ship reaches 10 years of age and at each subsequent intermediate and renewal survey. 1.1 Ice strengthened ships 1.1.1 Where bulk carriers are reinforced to comply with an ice class notation, the intermediate frames shall not be included when considering compliance with this annex. 1.1.2 The renewal thicknesses for the additional structure required to meet the ice strengthening notation shall be based on the classification society�s requirements. 1.1.3 If the ice class notation is requested to be withdrawn, the additional ice strengthening structure, with the exception of tripping brackets (see 2.1.2.1.b and 2.3), shall not be considered to contribute to compliance with this annex.



2 Renewal or other measures 2.1 Criteria for renewal or other measures 2.1.1 Symbols used in 2.1

tM = thickness as measured, in mm tREN = thickness at which renewal is required (2.1.2) tREN,d/t = thickness criteria based on d/t ratio (2.1.2.1) tREN,S = thickness criteria based on strength (2.1.2.2) tCOAT = 0.75 tS12 tS12 = thickness, in mm, as required by annex 1 in paragraph 3 for frame

webs and in paragraph 4 for upper and lower brackets tAB = thickness as built, in mm tC = See table 1 below

≥ 200 2 3 3 4

Note: For intermediate ship lengths, tC is obtained by linear interpolation between the above values.

2.1.2 Criteria for webs (shear and other checks) The webs of side shell frames and brackets shall be renewed when the measured thickness (tM) is equal to, or less than, the thickness (tREN) as defined below: tREN is the greatest of:

.1 tCOAT � tC .2 0.75 tAB .3 tREN,d/t

.4 tREN,S (where required by 2.1.2.2)


Page 11


2.1.2.1 Thickness criteria based on d/t ratio Subject to b) and c) below, tREN,d/t is given by the following equation:

tREN,d/t = (web depth in mm)/R where:

R = for frames

65 k0.5 for symmetrically flanged frames 55 k0.5 for asymmetrically flanged frames

for lower brackets (see a) below):

87 k0.5 for symmetrically flanged frames 73 k0.5 for asymmetrically flanged frames

k = 1 for ordinary hull structural steel; k = 0.78 for steel with yield stress of 315 N/mm²; and k = 0.72 for steel with yield stress of 355 N/mm².

In no instance shall tREN,d/t for lower integral brackets be taken as less than tREN,d/t for the frames they support.

a) Lower brackets

In calculating the web depth of the lower brackets, the following shall apply:

.1 The web depth of lower bracket may be measured from the intersection of

the sloped bulkhead of the hopper tank and the side shell plate, perpendicularly to the face plate of the lower bracket (see figure 3).

.2 Where stiffeners are fitted on the lower bracket plate, the web depth may

be taken as the distance between the side shell and the stiffener, between the stiffeners or between the outermost stiffener and the face plate of the brackets, whichever is the greatest.

b) Tripping bracket alternative

When tM is less than tREN,d/t at section b) of the side frames (see figure 2), tripping

brackets in accordance with 2.3 may be fitted as an alternative to the requirements for the web depth to thickness ratio of side frames, in which case tREN,d/t may be disregarded in the determination of tREN in accordance with 2.1.2.



c) Immediately abaft collision bulkhead

For the side frames located immediately abaft the collision bulkhead, whose

scantlings are increased in order that their moment of inertia is such as to avoid undesirable flexibility of the side shell, when their web as built thickness tAB is greater than 1.65tREN,S, the thickness tREN,d/t may be taken as the value t'REN,d/t obtained from the following equation:

S,REN2

t/d,RENt/d,REN tt't =

where tREN,S is obtained from 3.3.

2.1.2.2 Thickness criteria based on shear strength check Where tM in the lower part of side frames, as defined in figure 1, is equal to, or less than, tCOAT, tREN,S shall be determined in accordance with 3.3. 2.1.2.3 Thickness of renewed webs of frames and lower brackets Where steel renewal is required, the renewed webs shall be of a thickness not less than tAB, 1.2tCOAT or 1.2tREN, whichever is the greatest. 2.1.2.4 Criteria for other measures When tREN < tM ≤ tCOAT, measures shall be taken, consisting of all the following:

.1 sand blasting, or equivalent, and coating (see 2.2);

.2 fitting tripping brackets (see 2.3), when the above condition occurs for any of the side frame zones A, B, C and D, shown in figure 1; and

.3 maintaining the coating in �as new� condition (i.e. without breakdown or rusting)

at renewal and intermediate surveys. The above measures may be waived if the structural members show no thickness diminution with respect to the as-built thicknesses and coating is in �as new� condition (i.e. without breakdown or rusting). 2.1.3 Criteria for frames and brackets (bending check) Where the length or depth of the lower bracket does not meet the requirements in annex 1, a bending strength check in accordance with 3.4 shall be carried out and renewals or reinforcements of frames and/or brackets effected as required therein. 2.2 Thickness measurements, steel renewal, sand blasting and coating For the purpose of steel renewal, sand blasting and coating, four zones A, B, C and D are defined, as shown in figure 1.


Page 13


Representative thickness measurements shall be taken for each zone and shall be assessed against the criteria in 2.1. In case of integral brackets, when the criteria in 2.1 are not satisfied for zone A or B, steel renewal, sand blasting and coating, as applicable, shall be done for both zones A and B. In case of separate brackets, when the criteria in 2.1 are not satisfied for zone A or B, steel renewal, sand blasting and coating shall be done for each one of these zones, as applicable. When steel renewal is required for zone C according to 2.1, it shall be done for both zones B and C. When sand blasting and coating is required for zone C according to 2.1, it shall be done for zones B, C and D. When steel renewal is required for zone D according to 2.1, it needs only to be done for this zone. When sand blasting and coating is required for zone D according to 2.1, it shall be done for both zones C and D. Special consideration may be given to zones previously renewed or re-coated, if found in �as new� condition (i.e., without breakdown or rusting) by the Administration or a classification society which is recognized by the Administration in accordance with the provisions of SOLAS regulation XI-1/1. When adopted, on the basis of the renewal thickness criteria in 2.1, in general coating shall be applied in compliance with the requirements of the organization, as applicable. Where, according to the requirements in 2.1, a limited number of side frames and brackets are shown to require coating over part of their length, the following criteria apply:

.1 The part to be coated includes:

- the web and the face plate of the side frames and brackets,

- the hold surface of side shell, hopper tank and topside tank plating, as applicable, over a width not less than 100 mm from the web of the side frame.

.2 Epoxy coating or equivalent shall be applied.

In all cases, all the surfaces to be coated shall be sand blasted prior to coating application. 2.3 Reinforcing measures Reinforcing measures are constituted by tripping brackets, located at the lower part and at midspan of side frames (see figure 4). Tripping brackets may be located at every two frames, but lower and midspan brackets shall be fitted in line between alternate pairs of frames. The thickness of the tripping brackets shall be not less than the as-built thickness of the side frame webs to which they are connected.



Double continuous welding shall be adopted for the connections of tripping brackets to the side shell frames and shell plating. 2.4 Weld throat thickness In case of steel renewal, the welded connections shall comply with paragraph 7 of annex 1. 2.5 Pitting and grooving If pitting intensity is higher than 15% in area (see figure 5), thickness measurement shall be taken to check pitting corrosion. The minimum acceptable remaining thickness in pits or grooves is equal to:

.1 75% of the as-built thickness, for pitting or grooving in the frame and brackets webs and flanges; and

.2 70% of the as-built thickness, for pitting or grooving in the side shell, hopper tank

and topside tank plating attached to the side frame, over a width up to 30 mm from each side of it.

3 Strength check criteria In general, loads shall be calculated and strength checks shall be carried out for the aft, middle and forward frames of each hold. The scantlings required for frames in intermediate positions shall be obtained by linear interpolation between the results obtained for the above frames. When scantlings of side frames vary within a hold, the required scantlings shall also be calculated for the mid-frame of each group of frames having the same scantlings. The scantlings required for frames in intermediate positions shall be obtained by linear interpolation between the results obtained for the calculated frames. 3.1 Load model 3.1.1 Forces The forces Pfr,a and Pfr,b, in kN, to be considered for the strength checks at sections a) and b) of side frames (specified in figure 2; in the case of separate lower brackets, section b) is at the top of the lower bracket), are given by: Pfr,a = PS + max (P1, P2)

STANDARDS FOR OWNERS� INSPECTION AND MAINTENANCE OF

BULK CARRIER HATCH COVERS THE MARITIME SAFETY COMMITTEE, RECALLING Article 28(b) of the Convention on the International Maritime Organization concerning the functions of the Committee, RECALLING ALSO SOLAS chapter XII on Additional safety measures for bulk carriers, which the 1997 SOLAS Conference adopted with the aim of enhancing the safety of ships carrying solid bulk cargoes, RECALLING FURTHER that, having recognized the need to further improve the safety of bulk carriers in all aspects of their design, construction, equipment and operation, it examined the results of various formal safety assessment (FSA) studies on bulk carrier safety,

RECOGNIZING that, on the basis of the outcome of the aforementioned FSA studies, replacing hatch covers in existing bulk carriers would not be cost-effective and that, instead, more attention should be paid to hatch cover securing mechanisms and the issue of horizontal loads, especially with regard to maintenance and frequency of inspection,

RECALLING that, at its seventy-seventh session, in approving MSC/Circ.1071 � Guidelines for bulk carrier hatch cover surveys and owners� inspections and maintenance, it invited Member Governments to ensure that companies, as defined in the ISM Code, that operate bulk carriers flying their flag are made aware of the need to implement regular maintenance and inspection procedures for hatch cover closing mechanisms in existing bulk carriers in order to ensure proper operation and efficiency at all times, NOTING resolution MSC.170(79) by which it adopted, inter alia, amendments to regulation XII/7 (Survey and maintenance of bulk carriers) of the Convention, where reference is made to mandatory Standards for owners� inspection and maintenance of bulk carrier hatch covers, HAVING CONSIDERED the recommendation made by the Sub-Committee on Ship Design and Equipment at its forty-seventh session, 1. ADOPTS, for the purposes of the application of regulation XII/7 of the Convention, the Standards for owners� inspection and maintenance of bulk carrier hatch covers, set out in the Annex to the present resolution; 2. INVITES Contracting Governments to the Convention to note that the annexed Standards will take effect on 1 July 2006 upon the entry into force of the revised chapter XII of the Convention;



3. REQUESTS the Secretary-General to transmit certified copies of this resolution and the text of the annexed Standards to all Contracting Governments to the Convention; 4. FURTHER REQUESTS the Secretary-General to transmit certified copies of this resolution and the text of the annexed Standards to all Members of the Organization which are not Contracting Governments to the Convention.

ANNEX

STANDARDS FOR OWNERS� INSPECTION AND MAINTENANCE OF

BULK CARRIER HATCH COVERS 1 Application These Standards define requirements for the owners� inspection and maintenance of cargo hatch covers on board bulk carriers. 2 Maintenance of hatch covers and hatch opening, closing, securing and sealing

systems 2.1 Lack of weathertightness may be attributed to:

.1 normal wear and tear of the hatch cover system: deformation of the hatch coaming or cover due to impact; wear of the friction pads where fitted; wear and tear of the cleating arrangement; or

.2 lack of maintenance: corrosion of plating and stiffeners due to breakdown of

coatings; lack of lubrication of moving parts; cleats, joint gaskets and rubber pads in need of replacement, or replaced with incorrect specification parts.

2.2 Insecure hatch covers may be particularly attributed to damage or wear of securing devices, or incorrect adjustment, and incorrect pre-tension and load sharing, of cleating systems. 2.3 Ship owners and operators shall therefore institute a programme of maintenance. This maintenance shall be directed to:

.1 protecting exposed surfaces of plating and stiffeners of hatch covers and coamings in order to preserve overall structural strength;

.2 preserving the surface of trackways of rolling covers, and of compression bars and

other steel work bearing on seals or friction pads, noting that surface smoothness and correct profile are important for reducing wear rates on these components;

.3 maintaining hydraulic or mechanically powered opening, closing, securing or

cleating systems in accordance with manufacturer�s recommendations;

.4 maintaining manual cleats in adjustment, with replacement when significant wastage, wear or loss of adjustment capability is identified;

.5 replacing seals and other wear components in accordance with manufacturers�

recommendations, noting the need to carry on board or obtain such spares of correct specification, and that seals are designed for a particular degree of compression, hardness, chemical and wear resistance; and



.6 keeping all hatch cover drains and their non-return valves, where fitted, in

working order, noting that any drains fitted to the inboard side of seal lines will have non-return valves for prevention of water ingress to holds in the event of boarding seas.

2.4 The equalization of securing loads shall be maintained following the renewal of components such as seals, rubber washers, peripheral and cross joint cleats. 2.5 Ship owners and operators shall keep a Maintenance Plan and a record of maintenance and component replacement carried out, in order to facilitate maintenance planning and statutory surveys by the Administration. Hatch cover maintenance plans shall form part of a ship�s safety management system as referred to in the ISM Code. 2.6 Where the range of cargoes carried requires different gasket materials, a selection of gasket materials of the correct specifications shall be carried on board, in addition to other spares. 2.7 At each operation of a hatch cover, the cover and, in particular, bearing surfaces and drainage channels shall be free of debris and as clean as practicable. 2.8 Attention is drawn to the dangers of proceeding to sea without fully secured hatch covers. Securing of all covers shall always be completed before the commencement of a sea passage. During voyages, especially on loaded passages, cover securing devices and tightness of cleating and securing arrangements shall be checked, especially in anticipation of, and following periods of, severe weather. Hatch covers may only be opened on passage, when necessary, during favourable sea and weather conditions; imminent weather forecasts shall also be considered. 2.9 Operators shall consult the Cargo Securing Manual when planning the loading of containers or other cargo on hatch covers and confirm that they are designed and approved for such loads. Lashings shall not be secured to the covers or coamings unless these are suitable to withstand the lashing forces. 3 Inspection of hatch covers and hatch opening, closing, securing and sealing systems 3.1 Statutory surveys of hatch covers and their coamings are carried out by the Administration as part of the annual survey required by article 14 of the International Convention on Load Lines, 1966, as modified by the 1988 Protocol relating thereto and in accordance with the requirements for Enhanced Surveys contained in resolution A.744(18), as amended. However, the continued safe operation is dependent on the shipowner or operator instituting a regular programme of inspections to confirm the state of the hatch covers in between surveys. 3.2 Routines shall be established to perform checks during the voyage, and inspections when the hatch covers are opened. 3.3 Voyage checks shall consist of an external examination of the closed hatch covers and securing arrangements in anticipation of, and after, heavy weather but in any event at least once a week, weather permitting. Particular attention shall be paid to the condition of hatch covers in the forward 25% of the ship�s length, where sea loads are normally greatest.


Page 5


3.4 The following items, where provided, shall be inspected for each hatch cover set when the hatch covers are opened or are otherwise accessible on each voyage cycle, but need not be inspected more frequently than once per month:

.1 hatch cover panels, including side plates, and stiffener attachments of opened covers for visible corrosion, cracks or deformation;

.2 sealing arrangements of perimeter and cross joints (gaskets, flexible seals on

combination carriers, gasket lips, compression bars, drainage channels and non-return valves) for condition and permanent deformation;

.3 clamping devices, retaining bars and cleating for wastage, adjustment, and

condition of rubber components;

.4 closed cover locating devices for distortion and attachment;

.5 chain or wire rope pulleys;

.6 guides;

.7 guide rails and track wheels;

.8 stoppers;

.9 wires, chains, tensioners and gypsies;

.10 hydraulic system, electrical safety devices and interlocks; and

.11 end and inter-panel hinges, pins and stools where fitted. As part of this inspection, the coamings with their plating, stiffeners and brackets shall be checked at each hatchway for visible corrosion, cracks and deformation, especially of the coaming tops and corners, adjacent deck plating and brackets.

∗ In verifying the density of solid bulk cargoes, reference should be made to the Uniform method of

measurement of the density of bulk cargoes (MSC/Circ.908). ∗∗ Refer to the Recommendation on loading instruments, adopted by resolution 5 of the 1997 SOLAS

Conference. ∗∗∗ Refer to the relevant parts of the appendix to the Guidelines for the on-board use and application of

computers (MSC/Circ.891).

.1 in each cargo hold, giving audible and visual alarms, one when the water

level above the inner bottom in any hold reaches a height of 0.5 m and another at a height not less than 15% of the depth of the cargo hold but not more than 2 m. On bulk carriers to which regulation 9.2 applies, detectors with only the latter alarm need be installed. The water level detectors shall be fitted in the aft end of the cargo holds. For cargo holds which are used for water ballast, an alarm overriding device may be installed. The visual alarms shall clearly discriminate between the two different water levels detected in each hold;

.2 in any ballast tank forward of the collision bulkhead required by

regulation II-1/11, giving an audible and visual alarm when the liquid in the tank reaches a level not exceeding 10% of the tank capacity. An alarm overriding device may be installed to be activated when the tank is in use; and

.3 in any dry or void space other than a chain cable locker, any part of which

extends forward of the foremost cargo hold, giving an audible and visual alarm at a water level of 0.1 m above the deck. Such alarms need not be provided in enclosed spaces the volume of which does not exceed 0.1% of the ship�s maximum displacement volume.

2 The audible and visual alarms specified in paragraph 1 shall be located on the navigation bridge. 3 Bulk carriers constructed before 1 July 2004 shall comply with the requirements of this regulation not later than the date of the annual, intermediate or renewal survey of the ship to be carried out after 1 July 2004, whichever comes first.

Regulation 13

Availability of pumping systems∗ (This regulation applies to bulk carriers regardless of their date of construction) 1 On bulk carriers, the means for draining and pumping ballast tanks forward of the collision bulkhead and bilges of dry spaces any part of which extends forward of the foremost cargo hold shall be capable of being brought into operation from a readily accessible enclosed space, the location of which is accessible from the navigation bridge or propulsion machinery control position without traversing exposed freeboard or superstructure decks. Where pipes serving such tanks or bilges pierce the collision bulkhead, valve operation by means of remotely operated actuators may be accepted, as an alternative to the valve control specified in regulation II-1/11.4, provided that the location of such valve controls complies with this regulation.

∗ Refer to the Interpretation of SOLAS regulation XII/13 (MSC/Circ.1069).



2 Bulk carriers constructed before 1 July 2004 shall comply with the requirements of this regulation not later than the date of the first intermediate or renewal survey of the ship to be carried out after 1 July 2004, but, in no case, later than 1 July 2007.

Regulation 14

Restrictions from sailing with any hold empty

Bulk carriers of 150 m in length and upwards of single-side skin construction, carrying cargoes having a density of 1,780 kg/m3 and above, if not meeting the requirements for withstanding flooding of any one cargo hold as specified in regulation 5.1 and the Standards and criteria for side structures of bulk carriers of single-side skin construction, adopted by the Organization by resolution MSC.168(79), as may be amended by the Organization, provided that such amendments are adopted, brought into force and take effect in accordance with the provisions of article VIII of the present Convention concerning the amendment procedures applicable to the Annex other than chapter I, shall not sail with any hold loaded to less than 10% of the hold�s maximum allowable cargo weight when in the full load condition, after reaching 10 years of age. The applicable full load condition for this regulation is a load equal to or greater than 90% of the ship�s deadweight at the relevant assigned freeboard.�

2004 AMENDMENTS TO THE INTERNATIONAL CODE FOR THE CONSTRUCTION AND EQUIPMENT OF SHIPS CARRYING DANGEROUS

CHEMICALS IN BULK (IBC CODE)

The complete text of the IBC Code is replaced by the following:

�Preamble 1 The purpose of this Code is to provide an international standard for the safe carriage, in bulk by sea, of dangerous chemicals and noxious liquid substances listed in chapter 17 of the Code. The Code prescribes the design and construction standards of ships, regardless of tonnage, involved in such carriage and the equipment they shall carry to minimize the risk to the ship, its crew and the environment, having regard to the nature of the products involved. 2 The basic philosophy of the Code is to assign, to each chemical tanker, one of the ship types according to the degree of the hazards of the products carried by such ships. Each of the products may have one or more hazardous properties, including flammability, toxicity, corrosivity and reactivity, as well as the hazard they may present to the environment. 3 Throughout the development of the Code it was recognized that it must be based upon sound naval architectural and engineering principles and the best understanding available as to the hazards of the various products covered. Furthermore, chemical tanker design technology is not only a complex technology, but is rapidly evolving and therefore the Code should not remain static. Thus, the Organization will periodically review the Code, taking into account both experience and technical developments. 4 Amendments to the Code involving requirements for new products and their conditions of carriage will be circulated as recommendations, on an interim basis, when adopted by the Maritime Safety Committee (MSC) and the Marine Environment Protection Committee (MEPC) of the Organization, in accordance with the provisions of article VIII of the International Convention for the Safety of Life at Sea, 1974 (SOLAS 74), and article 16 of the International Convention for the Prevention of Pollution from Ships, 1973, as modified by the Protocol of 1978 relating thereto (MARPOL 73/78), respectively, pending the entry into force of these amendments. 5 The Code primarily deals with ship design and equipment. In order to ensure the safe transport of the products, the total system must, however, be appraised. Other important facets of the safe transport of the products, such as training, operation, traffic control and handling in port, are being, or will be, examined further by the Organization. 6 The development of the Code has been greatly assisted by a number of organizations in consultative status such as the Association of Classification Societies (IACS) and the International Electrotechnical Commission (IEC). 7 Chapter 16 of the Code, dealing with operational requirements of chemical tankers, highlights the regulations in other chapters that are operational in nature and mentions those other important safety features that are peculiar to chemical tanker operation.



8 The layout of the Code is in line with the International Code for the Construction and Equipment of Ships Carrying Liquefied Gases in Bulk (IGC Code), adopted by the Maritime Safety Committee at its forty-eighth session. Gas carriers may also carry in bulk liquid chemicals covered by this Code, as prescribed in the IGC Code. 9 The 1998 edition of the Code was based on the original text as adopted by MSC resolution MSC.4(48). In response to resolution 15 of the International Conference on Marine Pollution, 1973, the MEPC, at its twenty-second session, adopted, by resolution MEPC.19(22), the IBC Code extended to cover marine pollution prevention aspects for the implementation of Annex II to MARPOL 73/78. 10 This edition of the Code includes amendments adopted by the following resolutions: Resolution Adoption Deemed acceptance Entry into force 1 MSC.10(54) 29 April 1987 29 April 1988 30 October 1988 2 MSC.14(57)

11 As from the date of entry into force of the 1983 amendments to SOLAS 74 (i.e. 1 July 1986) and the date of implementation of Annex II of MARPOL 73/78 (i.e. 6 April 1987), this Code became subject to mandatory requirements under these Conventions. Amendments to the Code, whether from the point of view of safety or of marine pollution, must therefore be adopted and brought into force in accordance with the procedures laid down in article VIII of SOLAS 74 and article 16 of MARPOL 73/78 respectively.

Page 11


1.5.1.4 When a nominated surveyor or recognized organization determines that the condition of a ship or its equipment does not correspond substantially with the particulars of the International Certificate of Fitness for the Carriage of Dangerous Chemicals in Bulk, or is such that the ship is not fit to proceed to sea without danger to the ship, or persons on board, or without presenting unreasonable threat of harm to the marine environment, such surveyor or organization shall immediately ensure that corrective action is taken and shall, in due course, notify the Administration. If such corrective action is not taken the Certificate shall be withdrawn and the Administration shall be notified immediately. If the ship is in a port of another Contracting Government, the appropriate authorities of the port State shall also be notified immediately. When an officer of the Administration, a nominated surveyor or a recognized organization has notified the appropriate authorities of the port State, the Government of the port State concerned shall give such officer, surveyor or organization any necessary assistance to carry out their obligations under this paragraph. When applicable, the Government of the port State concerned shall take such steps as will ensure that the ship does not sail until it can proceed to sea or leave the port for the purpose of proceeding to the nearest appropriate repair yard available without danger to the ship or persons on board or without presenting an unreasonable threat of harm to the marine environment. 1.5.1.5 In every case, the Administration shall guarantee the completeness and efficiency of the survey, and shall undertake to ensure the necessary arrangements to satisfy this obligation. 1.5.2 Survey requirements 1.5.2.1 The structure, equipment, fittings, arrangements and material (other than items in respect of which a Cargo Ship Safety Construction Certificate, Cargo Ship Safety Equipment Certificate and Cargo Ship Safety Radio Certificate or Cargo Ship Safety Certificate are issued) of a chemical tanker shall be subjected to the following surveys:

.1 An initial survey before the ships is put in service or before the International Certificate of Fitness for the Carriage of Dangerous Chemicals in Bulk is issued for the first time, which shall include a complete examination of its structure, equipment, fittings, arrangements and material in so far as the ship is covered by the Code. This survey shall be such as to ensure that the structure, equipment, fittings, arrangements and material fully comply with the applicable provisions of the Code.

.2 A renewal survey at intervals specified by the Administration, but not exceeding

5 years, except where 1.5.6.2.2, 1.5.6.5, 1.5.6.6 or 1.5.6.7 is applicable. The renewal survey shall be such as to ensure that the structure, equipment, fittings, arrangements and material fully comply with the applicable provisions of the Code.

.3 An intermediate survey within 3 months before or after the second anniversary

date or within 3 months before or after the third anniversary date of the Certificate, which shall take the place of one of the annual surveys specified in 1.5.2.1.4. The intermediate survey shall be such as to ensure that the safety equipment, and other equipment, and associate pump and piping systems fully comply with the applicable provisions of the Code and are in good working order. Such intermediate surveys shall be endorsed on the Certificate issued under 1.5.4 or 1.5.5.



.4 An annual survey within 3 months before or after each anniversary date of the

Certificate, including a general inspection of the structure, equipment, fittings, arrangements and material referred to in 1.5.2.1.1 to ensure that they have been maintained in accordance with 1.5.3 and that they remain satisfactory for the service for which the ship is intended. Such annual surveys shall be endorsed on the Certificate issued under 1.5.4 or 1.5.5.

.5 An additional survey, either general or partial according to the circumstances,

shall be made when required after an investigation prescribed in 1.5.3.3, or whenever any important repairs or renewals are made. Such a survey shall ensure that the necessary repairs or renewals have been effectively made, that the material and workmanship of such repairs or renewals are satisfactory; and that the ship is fit to proceed to sea without danger to the ship or persons on board or without presenting unreasonable threat of harm to the marine environment.

1.5.3 Maintenance of conditions after survey 1.5.3.1 The conditions of the ship and its equipment shall be maintained to conform with the provisions of the Code to ensure that the ship will remain fit to proceed to sea without danger to the ship or persons on board or without presenting an unreasonable threat of harm to the marine environment. 1.5.3.2 After any survey of the ship under 1.5.2 has been completed, no change shall be made in the structure, equipment, fittings, arrangements and material covered by the survey, without the sanction of the Administration, except by direct replacement. 1.5.3.3 Whenever an accident occurs to a ship or a defect is discovered, either of which affects the safety of the ship or the efficiency or completeness of its life-saving appliances or other equipment covered by the Code, the master or owner of the ship shall report at the earliest opportunity to the Administration, the nominated surveyor or recognized organization responsible for issuing the Certificate, who shall cause investigations to be initiated to determine whether a survey, as required by 1.5.2.1.5, is necessary. If the ship is in a port of another Contracting Government, the master or owner shall also report immediately to the appropriate authorities of the port State and the nominated surveyor or recognized organization shall ascertain that such a report has been made. 1.5.4 Issue or endorsement of International Certificate of Fitness 1.5.4.1 An International Certificate of Fitness for the Carriage of Dangerous Chemicals in Bulk shall be issued after an initial or renewal survey to a chemical tanker engaged in international voyages which complies with the relevant provisions of the Code. 1.5.4.2 Such a Certificate shall be drawn up in the form corresponding to the model given in the appendix. If the language used is not English, French or Spanish, the text shall include the translation into one of these languages. 1.5.4.3 The Certificate issued under provisions of this section shall be available on board for examination at all times.


Page 13


1.5.5 Issue or endorsement of International Certificate of Fitness by another Government 1.5.5.1 A Government that is both a Contracting Government to the 1974 SOLAS Convention and a Party to MARPOL 73/78 may, at the request of another such Government, cause a ship entitled to fly the flag of the other State to be surveyed and, if satisfied that the provisions of the Code are complied with, issue or authorize the issue of the International Certificate of Fitness for the Carriage of Dangerous Chemicals in Bulk to the ship, and, where appropriate, endorse or authorize the endorsement of the Certificate on board the ship in accordance with the Code. Any Certificate so issued shall contain a statement to the effect that it has been issued at the request of the Government of the State whose flag the ship is entitled to fly. 1.5.6 Duration and validity of International Certificate of Fitness 1.5.6.1 An International Certificate of Fitness for the Carriage of Dangerous Chemicals in Bulk shall be issued for a period specified by the Administration which shall not exceed 5 years. 1.5.6.2.1 Notwithstanding the provisions of 1.5.6.1, when the renewal survey is completed within 3 months before the expiry date of the existing Certificate, the new Certificate shall be valid from the date of completion of the renewal survey to a date not exceeding 5 years from the date of expiry of the existing Certificate. 1.5.6.2.2 When the renewal survey is completed after the expiry date of the existing Certificate, the new Certificate shall be valid from the date of completion of the renewal survey to a date not exceeding 5 years from the date of expiry of the existing Certificate. 1.5.6.2.3 When the renewal survey is completed more than 3 months before the expiry date of the existing Certificate, the new Certificate shall be valid from the date of completion of the renewal survey to a date not exceeding 5 years from the date of completion of the renewal survey. 1.5.6.3 If a Certificate is issued for a period of less than 5 years, the Administration may extend the validity of the Certificate beyond the expiry date to the maximum period specified in 1.5.6.1, provided that the surveys referred to in 1.5.2.1.3 and 1.5.2.1.4, applicable when a Certificate is issued for a period of 5 years, are carried out as appropriate. 1.5.6.4 If a renewal survey has been completed and a new Certificate cannot be issued or placed on board the ship before the expiry date of the existing Certificate, the person or organization authorized by the Administration may endorse the existing Certificate. Such a Certificate shall be accepted as valid for a further period which shall not exceed 5 months from the expiry date. 1.5.6.5 If a ship, at the time when a Certificate expires, is not in a port in which it is to be surveyed, the Administration may extend the period of validity of the Certificate but this extension shall be granted only for the purpose of allowing the ship to complete its voyage to the port in which it is to be surveyed, and then only in cases where it appears proper and reasonable to do so. 1.5.6.6 A Certificate, issued to a ship engaged on short voyages which has not been extended under the foregoing provisions of this section, may be extended by the Administration for a period of grace of up to one month from the date of expiry stated on it. When the renewal survey is completed, the new Certificate shall be valid to a date not exceeding 5 years from the date of expiry of the existing Certificate before the extension was granted.



1.5.6.7 In special circumstances, as determined by the Administration, a new Certificate need not be dated from the date of expiry of the existing Certificate as required by 1.5.6.2.2, 1.5.6.5 or 1.5.6.6. In these special circumstances, the new Certificate shall be valid to a date not exceeding 5 years from the date of completion of the renewal survey. 1.5.6.8 If an annual or intermediate survey is completed before the period specified in 1.5.2, then:

.1 the anniversary date shown on the Certificate shall be amended by endorsement to a date which shall not be more than 3 months later than the date on which the survey was completed;

.2 the subsequent annual or intermediate survey required by 1.5.2 shall be completed

at the intervals prescribed by that section using the new anniversary date; and .3 the expiry date may remain unchanged provided one or more annual or

intermediate surveys, as appropriate, are carried out so that the maximum intervals between the surveys prescribed by 1.5.2 are not exceeded.

1.5.6.9 A Certificate issued under 1.5.4 or 1.5.5 shall cease to be valid in any of the following cases:

.1 if the relevant surveys are not completed within the periods specified under 1.5.2; .2 if the Certificate is not endorsed in accordance with 1.5.2.1.3 or 1.5.2.1.4; .3 upon transfer of the ship to the flag of another State. A new certificate shall only

be issued when the Government issuing the new Certificate is fully satisfied that the ship is in compliance with the requirements of 1.5.3.1 and 1.5.3.2. In the case of a transfer between Governments that are both a Contracting Government to the 1974 SOLAS Convention and a Party to MARPOL 73/78, if requested within 3 months after the transfer has taken place, the Government of the State whose flag the ship was formerly entitled to fly shall, as soon as possible, transmit to the Administration copies of the Certificate carried by the ship before the transfer and, if available, copies of the relevant survey reports.

Chapter 2

Ship survival capability and location of cargo tanks

2.1 General 2.1.1 Ships, subject to the Code, shall survive the normal effects of flooding following assumed hull damage caused by some external force. In addition, to safeguard the ship and the environment, the cargo tanks of certain types of ships shall be protected from penetration in the case of minor damage to the ship resulting, for example, from contact with a jetty or tug, and given a measure of protection from damage in the case of collision or stranding, by locating them at specified minimum distances inboard from the ship's shell plating. Both the assumed damage and the proximity of the cargo tanks to the ship's shell shall be dependent upon the degree of hazard presented by the products to be carried. 2.1.2 Ships subject to the Code shall be designed to one of the following standards:

.1 A type 1 ship is a chemical tanker intended to transport chapter 17 products with very severe environmental and safety hazards which require maximum preventive measures to preclude an escape of such cargo.

.2 A type 2 ship is a chemical tanker intended to transport chapter 17 products with

appreciably severe environmental and safety hazards which require significant preventive measures to preclude an escape of such cargo.

.3 A type 3 ship is a chemical tanker intended to transport chapter 17 products with

sufficiently severe environmental and safety hazards which require a moderate degree of containment to increase survival capability in a damaged condition.

Thus, a type 1 ship is a chemical tanker intended for the transportation of products considered to present the greatest overall hazard and type 2 and type 3 for products of progressively lesser hazards. Accordingly, a type 1 ship shall survive the most severe standard of damage and its cargo tanks shall be located at the maximum prescribed distance inboard from the shell plating. 2.1.3 The ship type required for individual products is indicated in column e in the table of chapter 17. 2.1.4 If a ship is intended to carry more than one product listed in chapter 17, the standard of damage shall correspond to that product having the most stringent ship type requirement. The requirements for the location of individual cargo tanks, however, are those for ship types related to the respective products intended to be carried. 2.2 Freeboard and intact stability 2.2.1 Ships subject to the Code may be assigned the minimum freeboard permitted by the International Convention on Load Lines in force. However, the draught associated with the assignment shall not be greater than the maximum draught otherwise permitted by this Code. 2.2.2 The stability of the ship in all seagoing conditions shall be to a standard which is acceptable to the Administration.



2.2.3 When calculating the effect of free surfaces of consumable liquids for loading conditions it shall be assumed that, for each type of liquid, at least one transverse pair or a single centre tank has a free surface and the tank or combination of tanks to be taken into account shall be those where the effect of free surfaces is the greatest. The free surface effect in undamaged compartments shall be calculated by a method acceptable to the Administration. 2.2.4 Solid ballast shall not normally be used in double-bottom spaces in the cargo area. Where, however, because of stability considerations, the fitting of solid ballast in such spaces becomes unavoidable, then its disposition shall be governed by the need to ensure that the impact loads resulting from bottom damage are not directly transmitted to the cargo tank structure. 2.2.5 The master of the ship shall be supplied with a loading and stability information booklet. This booklet shall contain details of typical service and ballast conditions, provisions for evaluating other conditions of loading and a summary of the ship's survival capabilities. In addition, the booklet shall contain sufficient information to enable the master to load and operate the ship in a safe and seaworthy manner. 2.3 Shipside discharges below the freeboard deck 2.3.1 The provision and control of valves fitted to discharges led through the shell from spaces below the freeboard deck or from within the super-structures and deck-houses on the freeboard deck fitted with weathertight doors shall comply with the requirements of the relevant regulation of the International Convention on Load Lines in force, except that the choice of valves shall be limited to:

.1 one automatic non-return valve with a positive means of closing from above the freeboard deck; or

.2 where the vertical distance from the summer load waterline to the inboard end of

the discharge pipe exceeds 0.01L, two automatic non-return valves without positive means of closing, provided that the inboard valve is always accessible for examination under service conditions.

2.3.2 For the purpose of this chapter, �summer load line� and �freeboard deck� have the meanings as defined in the International Convention on Load Lines in force. 2.3.3 The automatic non-return valves referred to in 2.3.1.1 and 2.3.1.2 shall be fully effective in preventing admission of water into the ship, taking into account the sinkage, trim and heel in survival requirements in 2.9, and shall comply with recognized standards. 2.4 Conditions of loading Damage survival capability shall be investigated on the basis of loading information submitted to the Administration for all anticipated conditions of loading and variations in draught and trim. Ballast conditions where the chemical tanker is not carrying products covered by the Code, or is carrying only residues of such products, need not be considered.


Page 17


2.5 Damage assumptions 2.5.1 The assumed maximum extent of damage shall be:

.1 Side damage:

.1.1 Longitudinal extent: 1/3L2/3 or 14.5 m, whichever is less

.1.2 Transverse extent B/5 or 11.5 m, whichever is less (measured inboard from the ship�s side at right angles to the centreline at the level of the summer load line)

.1.3 Vertical extent:

upwards without limit (measured from the moulded line of the bottom shell plating at centreline)

.2

Bottom damage:

For 0.3L from the forward perpendicular of the ship

Any other part of the ship

.2.1 Longitudinal extent: 1/3L2/3 or 14.5 m, whichever is less

1/3L2/3 or 5 m, whichever is less

.2.2 Transverse extent: B/6 or 10 m, whichever is less

B/6 or 5 m, whichever is less

.2.3 Vertical extent: B/15 or 6 m, whichever is less [measured from the moulded line of the bottom shell plating at centreline (see 2.6.2)]

B/15 or 6 m, whichever is less [measured from the moulded line of the bottom shell plating at centreline (see 2.6.2)]

2.5.2 If any damage of a lesser extent than the maximum damage specified in 2.5.1 would result in a more severe condition, such damage shall be considered. 2.6 Location of cargo tanks 2.6.1 Cargo tanks shall be located at the following distances inboard:

.1 Type 1 ships: from the side shell plating, not less than the transverse extent of damage specified in 2.5.1.1.2, and from the moulded line of the bottom shell plating at centreline, not less than the vertical extent of damage specified in 2.5.1.2.3, and nowhere less than 760 mm from the shell plating. This requirement does not apply to the tanks for diluted slops arising from tank washing.

.2 Type 2 ships: from the moulded line of the bottom shell plating at centreline, not

less than the vertical extent of damage specified in 2.5.1.2.3, and nowhere less than 760 mm from the shell plating. This requirement does not apply to the tanks for diluted slops arising from tank washing.

.3 Type 3 ships: no requirement.



2.6.2 Except for type 1 ships, suction wells installed in cargo tanks may protrude into the vertical extent of bottom damage specified in 2.5.1.2.3 provided that such wells are as small as practicable and the protrusion below the inner bottom plating does not exceed 25% of the depth of the double bottom or 350 mm, whichever is less. Where there is no double bottom, the protrusion of the suction well of independent tanks below the upper limit of bottom damage shall not exceed 350 mm. Suction wells installed in accordance with this paragraph may be ignored in determining the compartments affected by damage. 2.7 Flooding assumptions 2.7.1 The requirements of 2.9 shall be confirmed by calculations which take into consideration the design characteristics of the ship; the arrangements, configuration and contents of the damaged compartments; the distribution, relative densities and the free surface effects of liquids; and the draught and trim for all conditions of loading. 2.7.2 The permeabilities of spaces assumed to be damaged shall be as follows:

Spaces Permeabilities Appropriated to stores 0.60 Occupied by accommodation 0.95 Occupied by machinery 0.85 Voids 0.95 Intended for consumable liquids 0 to 0.95* Intended for other liquids 0 to 0.95*

2.7.3 Wherever damage penetrates a tank containing liquids it shall be assumed that the contents are completely lost from that compartment and replaced by salt water up to the level of the final plane of equilibrium. 2.7.4 Every watertight division within the maximum extent of damage defined in 2.5.1 and considered to have sustained damage in positions given in 2.8.1 shall be assumed to be penetrated. Where damage less than the maximum is being considered in accordance with 2.5.2, only watertight divisions or combinations of watertight divisions within the envelope of such lesser damage shall be assumed to be penetrated. 2.7.5 The ship shall be so designed as to keep unsymmetrical flooding to the minimum consistent with efficient arrangements. 2.7.6 Equalization arrangements requiring mechanical aids such as valves or cross-levelling pipes, if fitted, shall not be considered for the purpose of reducing an angle of heel or attaining the minimum range of residual stability to meet the requirements of 2.9 and sufficient residual stability shall be maintained during all stages where equalization is used. Spaces which are linked by ducts of large cross-sectional area may be considered to be common. 2.7.7 If pipes, ducts, trunks or tunnels are situated within the assumed extent of damage penetration, as defined in 2.5, arrangements shall be such that progressive flooding cannot thereby extend to compartments other than those assumed to be flooded for each case of damage.

* The permeability of partially filled compartments shall be consistent with the amount of liquid carried in the

compartment.


Page 19


2.7.8 The buoyancy of any superstructure directly above the side damage shall be disregarded. The unflooded parts of superstructures beyond the extent of damage, however, may be taken into consideration provided that:

.1 they are separated from the damaged space by watertight divisions and the requirements of 2.9.3 in respect of these intact spaces are complied with; and

.2 openings in such divisions are capable of being closed by remotely operated

sliding watertight doors and unprotected openings are not immersed within the minimum range of residual stability required in 2.9; however, the immersion of any other openings capable of being closed weathertight may be permitted.

2.8 Standard of damage 2.8.1 Ships shall be capable of surviving the damage indicated in 2.5 with the flooding assumptions in 2.7 to the extent determined by the ship's type according to the following standards:

.1 A type 1 ship shall be assumed to sustain damage anywhere in its length.

.2 A type 2 ship of more than 150 m in length shall be assumed to sustain damage anywhere in its length.

.3 A type 2 ship of 150 m in length or less shall be assumed to sustain damage

anywhere in its length except involving either of the bulkheads bounding a machinery space located aft.

.4 A type 3 ship of more than 225 m in length shall be assumed to sustain damage

anywhere in its length.

.5 A type 3 ship of 125 m in length or more but not exceeding 225 m in length shall be assumed to sustain damage anywhere in its length except involving either of the bulkheads bounding a machinery space located aft.

.6 A type 3 ship below 125 m in length shall be assumed to sustain damage

anywhere in its length except involving damage to the machinery space when located aft. However, the ability to survive the flooding of the machinery space shall be considered by the Administration.

2.8.2 In the case of small type 2 and type 3 ships which do not comply in all respects with the appropriate requirements of 2.8.1.3 and 2.8.1.6, special dispensation may only be considered by the Administration provided that alternative measures can be taken which maintain the same degree of safety. The nature of the alternative measures shall be approved and clearly stated and be available to the port Administration. Any such dispensation shall be duly noted on the International Certificate of Fitness referred to in 1.5.4.



2.9 Survival requirements 2.9.1 Ships subject to the Code shall be capable of surviving the assumed damage specified in 2.5 to the standard provided in 2.8 in a condition of stable equilibrium and shall satisfy the following criteria. 2.9.2 In any stage of flooding:

.1 the waterline, taking into account sinkage, heel and trim, shall be below the lower edge of any opening through which progressive flooding or downflooding may take place. Such openings shall include air pipes and openings which are closed by means of weathertight doors or hatch covers and may exclude those openings closed by means of watertight manhole covers and watertight flush scuttles, small watertight cargo tank hatch covers which maintain the high integrity of the deck, remotely operated watertight sliding doors, and sidescuttles of the non-opening type;

.2 the maximum angle of heel due to unsymmetrical flooding shall not exceed 25°,

except that this angle may be increased to 30° if no deck immersion occurs;

.3 the residual stability during intermediate stages of flooding shall be to the satisfaction of the Administration. However, it shall never be significantly less than that required by 2.9.3.

2.9.3 At final equilibrium after flooding:

.1 the righting-lever curve shall have a minimum range of 20° beyond the position of equilibrium in association with a maximum residual righting lever of at least 0.1 m within the 20° range; the area under the curve within this range shall not be less than 0.0175 m radians. Unprotected openings shall not be immersed within this range unless the space concerned is assumed to be flooded. Within this range, the immersion of any of the openings listed in 2.9.2.1 and other openings capable of being closed weathertight may be permitted; and

.2 the emergency source of power shall be capable of operating.

Chapter 3

Ship arrangements

3.1 Cargo segregation 3.1.1 Unless expressly provided otherwise, tanks containing cargo or residues of cargo subject to the Code shall be segregated from accommodation, service and machinery spaces and from drinking water and stores for human consumption by means of a cofferdam, void space, cargo pump-room, pump-room, empty tank, oil fuel tank or other similar space. 3.1.2 Cargo piping shall not pass through any accommodation, service or machinery space other than cargo pump-rooms or pump-rooms. 3.1.3 Cargoes, residues of cargoes or mixtures containing cargoes, which react in a hazardous manner with other cargoes, residues or mixtures, shall:

.1 be segregated from such other cargoes by means of a cofferdam, void space, cargo pump-room, pump-room, empty tank, or tank containing a mutually compatible cargo;

.2 have separate pumping and piping systems which shall not pass through other

cargo tanks containing such cargoes, unless encased in a tunnel; and

.3 have separate tank venting systems. 3.1.4 If cargo piping systems or cargo ventilation systems are to be separated. This separation may be achieved by the use of design or operational methods. Operational methods shall not be used within a cargo tank and shall consist of one of the following types:

.1 removing spool-pieces or valves and blanking the pipe ends;

.2 arrangement of two spectacle flanges in series, with provisions for detecting leakage into the pipe between the two spectacle flanges.

3.1.5 Cargoes subject to the Code shall not be carried in either the fore or aft peak tank. 3.2 Accommodation, service and machinery spaces and control stations 3.2.1 No accommodation or service spaces or control stations shall be located within the cargo area except over a cargo pump-room recess or pump-room recess that complies with SOLAS regulations II-2/4.5.1 to 4.5.2.4 and no cargo or slop tank shall be aft of the forward end of any accommodation. 3.2.2 In order to guard against the danger of hazardous vapours, due consideration shall be given to the location of air intakes and openings into accommodation, service and machinery spaces and control stations in relation to cargo piping and cargo vent systems.



3.2.3 Entrances, air inlets and openings to accommodation, service and machinery spaces and control stations shall not face the cargo area. They shall be located on the end bulkhead not facing the cargo area and/or on the outboard side of the superstructure or deck-house at a distance of at least 4% of the length (L) of the ship but not less than 3 m from the end of the superstructure or deck-house facing the cargo area. This distance, however, need not exceed 5 m. No doors shall be permitted within the limits mentioned above, except that doors to those spaces not having access to accommodation and service spaces and control stations, such as cargo control stations and store-rooms, may be fitted. Where such doors are fitted, the boundaries of the space shall be insulated to �A-60� standard. Bolted plates for removal of machinery may be fitted within the limits specified above.

Chapter 4

Cargo containment 4.1 Definitions 4.1.1 Independent tank means a cargo-containment envelope, which is not contiguous with, or part of, the hull structure. An independent tank is built and installed so as to eliminate whenever possible (or in any event to minimize) its stressing as a result of stressing or motion of the adjacent hull structure. An independent tank is not essential to the structural completeness of the ship's hull. 4.1.2 Integral tank means a cargo-containment envelope which forms part of the ship's hull and which may be stressed in the same manner and by the same loads which stress the contiguous hull structure and which is normally essential to the structural completeness of the ship's hull. 4.1.3 Gravity tank means a tank having a design pressure not greater than 0.07 MPa gauge at the top of the tank. A gravity tank may be independent or integral. A gravity tank shall be constructed and tested according to recognized standards, taking account of the temperature of carriage and relative density of the cargo. 4.1.4 Pressure tank means a tank having a design pressure greater than 0.07 MPa gauge. A pressure tank shall be an independent tank and shall be of a configuration permitting the application of pressure-vessel design criteria according to recognized standards. 4.2 Tank type requirements for individual products Requirements for both installation and design of tank types for individual products are shown in column f in the table of chapter 17.

However, relaxations from these requirements may be accepted in accordance with recognized standards for piping inside tanks and open-ended piping.



5.4.2 After assembly, each cargo piping system shall be subject to a hydrostatic test to at least 1.5 times the design pressure. When piping systems or parts of systems are completely manufactured and equipped with all fittings, the hydrostatic test may be conducted prior to installation aboard the ship. Joints welded on board shall be hydrostatically tested to at least 1.5 times the design pressure. 5.4.3 After assembly on board, each cargo piping system shall be tested for leaks to a pressure depending on the method applied. 5.5 Piping arrangements 5.5.1 Cargo piping shall not be installed under deck between the out-board side of the cargo-containment spaces and the skin of the ship unless clearances required for damage protection (see 2.6) are maintained; but such distances may be reduced where damage to the pipe would not cause release of cargo provided that the clearance required for inspection purposes is maintained. 5.5.2 Cargo piping located below the main deck may run from the tank it serves and penetrate tank bulkheads or boundaries common to longitudinally or transversally adjacent cargo tanks, ballast tanks, empty tanks, pump-rooms or cargo pump-rooms provided that inside the tank it serves it is fitted with a stop-valve operable from the weather deck and provided cargo compatibility is assured in the event of piping failure. As an exception, where a cargo tank is adjacent to a cargo pump-room, the stop valve operable from the weather deck may be situated on the tank bulkhead on the cargo pump-room side, provided an additional valve is fitted between the bulkhead valve and the cargo pump. A totally enclosed hydraulically operated valve located outside the cargo tank may, however, be accepted, provided that the valve is:

.1 designed to preclude the risk of leakage;

.2 fitted on the bulkhead of the cargo tank which it serves;

.3 suitably protected against mechanical damage;

.4 fitted at a distance from the shell as required for damage protection; and

5.6 Cargo-transfer control systems 5.6.1 For the purpose of adequately controlling the cargo, cargo-transfer systems shall be provided with:

.1 one stop-valve capable of being manually operated on each tank filling and discharge line, located near the tank penetration; if an individual deepwell pump is used to discharge the contents of a cargo tank, a stop-valve is not required on the discharge line of that tank;

.2 one stop valve at each cargo-hose connection;

.3 remote shutdown devices for all cargo pumps and similar equipment.

5.6.2 The controls necessary during transfer or transport of cargoes covered by the Code other than in cargo pump-rooms which have been dealt with elsewhere in the Code shall not be located below the weather deck. 5.6.3 For certain products, additional cargo-transfer control requirements are shown in column o in the table of chapter 17. 5.7 Ship's cargo hoses 5.7.1 Liquid and vapour hoses used for cargo transfer shall be compatible with the cargo and suitable for the cargo temperature. 5.7.2 Hoses subject to tank pressure or the discharge pressure of pumps shall be designed for a bursting pressure not less than 5 times the maximum pressure the hose will be subjected to during cargo transfer. 5.7.3 For cargo hoses installed on board ships on or after 1 July 2002, each new type of cargo hose, complete with end-fittings, shall be prototype-tested at a normal ambient temperature with 200 pressure cycles from zero to at least twice the specified maximum working pressure. After this cycle pressure test has been carried out, the prototype test shall demonstrate a bursting pressure of at least 5 times its specified maximum working pressure at the extreme service temperature. Hoses used for prototype testing shall not be used for cargo service. Thereafter, before being placed in service, each new length of cargo hose produced shall be hydrostatically tested at ambient temperature to a pressure not less than 1.5 times its specified maximum working pressure but not more than two-fifths of its bursting pressure. The hose shall be stencilled or otherwise marked with the date of testing, its specified maximum working pressure and, if used in services other than the ambient temperature services, its maximum and minimum service temperature, as applicable.

Steel is assumed to be the normal material of construction. 6.2 The shipyard is responsible for providing compatibility information to the ship operator and/or master. This must be done in a timely manner before delivery of the ship or on completion of a relevant modification of the material of construction. 6.3 Where applicable, the following should be taken into account in selecting the material of construction: .1 notch ductility at the operating temperature; .2 corrosive effect of the cargo; and .3 possibility of hazardous reactions between the cargo and the material of

construction. 6.4 The shipper of the cargo is responsible for providing compatibility information to the ship operator and/or master. This must be done in a timely manner before transportation of the product. The cargo shall be compatible with all materials of construction such that:

.1 no damage to the integrity of the materials of construction is incurred; and/or .2 no hazardous, or potentially hazardous reaction is created. 6.5 When a product is submitted to IMO for evaluation, and where compatibility of the product with materials referred to in paragraph 6.1 renders special requirements, the BLG Product Data Reporting form shall provide information on the required materials of construction. These requirements shall be reflected in chapter 15 and consequentially be referred to in column o of chapter 17. The reporting form shall also indicate if no special requirements are necessary. The producer of the product is responsible for providing the correct information.

Cargo temperature control

7.1 General 7.1.1 When provided, any cargo heating or cooling systems shall be constructed, fitted and tested to the satisfaction of the Administration. Materials used in the construction of temperature-control systems shall be suitable for use with the product intended to be carried. 7.1.2 Heating or cooling media shall be of a type approved for use with the specific cargo. Consideration shall be given to the surface temperature of heating coils or ducts to avoid dangerous reactions from localized overheating or overcooling of cargo. (See also 15.13.6.) 7.1.3 Heating or cooling systems shall be provided with valves to isolate the system for each tank and to allow manual regulation of flow. 7.1.4 In any heating or cooling system, means shall be provided to ensure that, when in any condition other than empty, a higher pressure can be maintained within the system than the maximum pressure head that could be exerted by the cargo tank contents on the system. 7.1.5 Means shall be provided for measuring the cargo temperature.

.1 The means for measuring the cargo temperature shall be of restricted or closed type, respectively, when a restricted or closed gauging device is required for individual substances, as shown in column j in the table of chapter 17.

.2 A restricted temperature-measuring device is subject to the definition for a

restricted gauging device in 13.1.1.2 (e.g. a portable thermometer lowered inside a gauge tube of the restricted type).

.3 A closed temperature-measuring device is subject to the definition for a closed

gauging device in 13.1.1.3 (e.g. a remote-reading thermometer of which the sensor is installed in the tank).

.4 When overheating or overcooling could result in a dangerous condition, an alarm

system which monitors the cargo temperature shall be provided. (See also operational requirements in 16.6.)

7.1.6 When products for which 15.12, 15.12.1 or 15.12.3 are listed in column o in the table of chapter 17 are being heated or cooled, the heating or cooling medium shall operate in a circuit:

.1 which is independent of other ship's services, except for another cargo heating or cooling system, and which does not enter the machinery space; or

.2 which is external to the tank carrying toxic products; or



.3 where the medium is sampled to check for the presence of cargo before it is

recirculated to other services of the ship or into the machinery space. The sampling equipment shall be located within the cargo area and be capable of detecting the presence of any toxic cargo being heated or cooled. Where this method is used, the coil return shall be tested not only at the commencement of heating or cooling of a toxic product, but also on the first occasion the coil is used subsequent to having carried an unheated or uncooled toxic cargo.

7.2 Additional requirements For certain products, additional requirements contained in chapter 15 are shown in column o in the table of chapter 17.

Chapter 8

Cargo tank venting and gas-freeing arrangements

8.1 Application 8.1.1 Unless expressly provided otherwise, this chapter applies to ships constructed on or after 1 January 1994. 8.1.2 Ships constructed before 1 January 1994 shall comply with the requirements of chapter 8 of this Code which were in force prior to the said date. 8.1.3 For the purpose of this regulation, the term �ship constructed� is as defined in SOLAS regulation II-1/1.3.1. 8.1.4 Ships constructed on or after 1 July 1986 but before 1 January 1994 which fully comply with the requirements of the Code applicable at that time may be regarded as complying with the requirements of SOLAS regulations II-2/4.5.3, 4.5.6 to 4.5.8, 4.5.10 and 11.6. 8.1.5 For ships to which the Code applies, the requirements of this chapter shall apply in lieu of SOLAS regulations II-2/4.5.3 and 4.5.6. 8.1.6 Ships constructed on or after 1 July 1986, but before 1 July 2002 shall comply with the requirements of 8.3.3. 8.2 Cargo tank venting 8.2.1 All cargo tanks shall be provided with a venting system appropriate to the cargo being carried and these systems shall be independent of the air pipes and venting systems of all other compartments of the ship. Tank venting systems shall be designed so as to minimize the possibility of cargo vapour accumulating about the decks, entering accommodation, service and machinery spaces and control stations and, in the case of flammable vapours, entering or collecting in spaces or areas containing sources of ignition. Tank venting systems shall be arranged to prevent entrance of water into the cargo tanks and, at the same time, vent outlets shall direct the vapour discharge upwards in the form of unimpeded jets. 8.2.2 The venting systems shall be connected to the top of each cargo tank and as far as practicable the cargo vent lines shall be self-draining back to the cargo tanks under all normal operational conditions of list and trim. Where it is necessary to drain venting systems above the level of any pressure/vacuum valve, capped or plugged drain cocks shall be provided. 8.2.3 Provision shall be made to ensure that the liquid head in any tank does not exceed the design head of the tank. Suitable high-level alarms, overflow control systems or spill valves, together with gauging and tank filling procedures, may be accepted for this purpose. Where the means of limiting cargo tank overpressure includes an automatic closing valve, the valve shall comply with the appropriate provisions of 15.19.



8.2.4 Tank venting systems shall be designed and operated so as to ensure that neither pressure nor vacuum created in the cargo tanks during loading or unloading exceeds tank design parameters. The main factors to be considered in the sizing of a tank venting system are as follows:

.1 design loading and unloading rate;

.2 gas evolution during loading: this shall be taken account of by multiplying the maximum loading rate by a factor of at least 1.25;

.3 density of the cargo vapour mixture;

.4 pressure loss in vent piping and across valves and fittings; and

.5 pressure/vacuum settings of relief devices.

8.2.5 Tank vent piping connected to cargo tanks of corrosion-resistant material, or to tanks which are lined or coated to handle special cargoes as required by the Code, shall be similarly lined or coated or constructed of corrosion-resistant material. 8.2.6 The master shall be provided with the maximum permissible loading and unloading rates for each tank or group of tanks consistent with the design of the venting systems. 8.3 Types of tank venting systems 8.3.1 An open tank venting system is a system which offers no restriction except for friction losses to the free flow of cargo vapours to and from the cargo tanks during normal operations. An open venting system may consist of individual vents from each tank, or such individual vents may be combined into a common header or headers, with due regard to cargo segregation. In no case shall shutoff valves be fitted either to the individual vents or to the header. 8.3.2 A controlled tank venting system is a system in which pressure- and vacuum-relief valves or pressure/vacuum valves are fitted to each tank to limit the pressure or vacuum in the tank. A controlled venting system may consist of individual vents from each tank or such individual vents on the pressure side only as may be combined into a common header or headers, with due regard to cargo segregation. In no case shall shut-off valves be fitted either above or below pressure- or vacuum-relief valves or pressure/vacuum valves. Provision may be made for bypassing a pressure- or vacuum-relief valve or pressure/vacuum valve under certain operating conditions provided that the requirement of 8.3.6 is maintained and that there is suitable indication to show whether or not the valve is bypassed. 8.3.3 Controlled tank venting systems shall consist of a primary and a secondary means of allowing full flow relief of vapour to prevent over-pressure or under-pressure in the event of failure of one means. Alternatively, the secondary means may consist of pressure sensors fitted in each tank with a monitoring system in the ship's cargo control room or position from which cargo operations are normally carried out. Such monitoring equipment shall also provide an alarm facility which is activated by detection of over-pressure or under-pressure conditions within a tank.


Page 37


8.3.4 The position of vent outlets of a controlled tank venting system shall be arranged:

.1 at a height of not less than 6 m above the weather deck or above a raised walkway if fitted within 4 m of the raised walkway; and

.2 at a distance of at least 10 m measured horizontally from the nearest air intake or

opening to accommodation, service and machinery spaces and ignition sources. 8.3.5 The vent outlet height referred to in 8.3.4.1 may be reduced to 3 m above the deck or a raised walkway, as applicable, provided that high-velocity venting valves of an approved type, directing the vapour/air mixture upwards in an unimpeded jet with an exit velocity of at least 30 m/s, are fitted. 8.3.6 Controlled tank venting systems fitted to tanks to be used for cargoes having a flashpoint not exceeding 60°C (closed-cup test) shall be provided with devices to prevent the passage of flame into the cargo tanks. The design, testing and locating of the devices shall comply with the requirements of the Administration, which shall contain at least the standards adopted by the Organization. 8.3.7 In designing venting systems and in the selection of devices to prevent the passage of flame for incorporation into the tank venting system, due attention shall be paid to the possibility of the blockage of these systems and fittings by, for example, the freezing of cargo vapour, polymer build-up, atmospheric dust or icing up in adverse weather conditions. In this context it shall be noted that flame arresters and flame screens are more susceptible to blockage. Provisions shall be made such that the system and fittings may be inspected, operationally checked, cleaned or renewed as applicable. 8.3.8 Reference in 8.3.1 and 8.3.2 to the use of shutoff valves in the venting lines shall be interpreted to extend to all other means of stoppage, including spectacle blanks and blank flanges. 8.4 Venting requirements for individual products Venting requirements for individual products are shown in column g, and additional requirements in column o in the table of chapter 17. 8.5 Cargo tank gas-freeing 8.5.1 The arrangements for gas-freeing cargo tanks used for cargoes other than those for which open venting is permitted shall be such as to minimize the hazards due to the dispersal of flammable or toxic vapours in the atmosphere and to flammable or toxic vapour mixtures in a cargo tank. Accordingly, gas-freeing operations shall be carried out such that vapour is initially discharged:

.1 through the vent outlets specified in 8.3.4 and 8.3.5; or

.2 through outlets at least 2 m above the cargo tank deck level with a vertical exit velocity of at least 30 m/s maintained during the gas-freeing operation; or



.3 through outlets at least 2 m above the cargo tank deck level with a vertical exit

velocity of at least 20 m/s which are protected by suitable devices to prevent the passage of flame.

When the flammable vapour concentration at the outlets has been reduced to 30% of the lower flammable limit and, in the case of a toxic product, the vapour concentration does not present a significant health hazard, gas-freeing may thereafter be continued at cargo tank deck level. 8.5.2 The outlets referred to in 8.5.1.2 and 8.5.1.3 may be fixed or portable pipes. 8.5.3 In designing a gas-freeing system in conformity with 8.5.1, particularly in order to achieve the required exit velocities of 8.5.1.2 and 8.5.1.3, due consideration shall be given to the following:

.1 materials of construction of system;

.2 time to gas-free;

.3 flow characteristics of fans to be used;

.4 the pressure losses created by ducting, piping, cargo tank inlets and outlets;

.5 the pressure achievable in the fan driving medium (e.g. water or compressed air); and

.6 the densities of the cargo vapour/air mixtures for the range of cargoes to be

carried.

Chapter 9

Environmental control 9.1 General 9.1.1 Vapour spaces within cargo tanks and, in some cases, spaces surrounding cargo tanks may require to have specially controlled atmospheres. 9.1.2 There are four different types of control for cargo tanks, as follows:

.1 Inerting: by filling the cargo tank and associated piping systems and, where specified in chapter 15, the spaces surrounding the cargo tanks, with a gas or vapour which will not support combustion and which will not react with the cargo, and maintaining that condition.

.2 Padding: by filling the cargo tank and associated piping systems with a liquid,

gas or vapour which separates the cargo from the air, and maintaining that condition.

.3 Drying: by filling the cargo tank and associated piping systems with moisture-

free gas or vapour with a dewpoint of -40°C or below at atmospheric pressure, and maintaining that condition.

Instrumentation

13.1 Gauging 13.1.1 Cargo tanks shall be fitted with one of the following types of gauging devices: .1 Open device: which makes use of an opening in the tanks and may expose the

gauger to the cargo or its vapour. An example of this is the ullage opening. .2 Restricted device: which penetrates the tank and which, when in use, permits a

small quantity of cargo vapour or liquid to be exposed to the atmosphere. When not in use, the device is completely closed. The design shall ensure that no dangerous escape of tank contents (liquid or spray) can take place in opening the device.

.3 Closed device: which penetrates the tank, but which is part of a closed system and

keeps tank contents from being released. Examples are the float-type systems, electronic probe, magnetic probe and protected sight-glass. Alternatively, an indirect device which does not penetrate the tank shell and which is independent of the tank may be used. Examples are weighing of cargo, pipe flow meter.

13.1.2 Gauging devices shall be independent of the equipment required under 15.19. 13.1.3 Open gauging and restricted gauging shall be allowed only where: .1 open venting is allowed by the Code; or .2 means are provided for relieving tank pressure before the gauge is operated. 13.1.4 Types of gauging for individual products are shown in column j in the table of chapter 17. 13.2 Vapour detection 13.2.1 Ships carrying toxic or flammable products or both shall be equipped with at least two instruments designed and calibrated for testing for the specific vapours in question. If such instruments are not capable of testing for both toxic concentrations and flammable concentrations, then two separate sets of instruments shall be provided. 13.2.2 Vapour-detection instruments may be portable or fixed. If a fixed system is installed, at least one portable instrument shall be provided. 13.2.3 When toxic-vapour-detection equipment is not available for some products which require such detection, as indicated in column k in the table of chapter 17, the Administration may exempt the ship from the requirement, provided an appropriate entry is made on the International Certificate of Fitness for the Carriage of Dangerous Chemicals in Bulk.

15.5.2.10 Only those hydrogen peroxide solutions which have a maximum decomposition rate of 1% per year at 25°C shall be carried. Certification from the shipper that the product meets this standard shall be presented to the master and kept on board. A technical representative of the manufacturer shall be on board to monitor the transfer operations and have the capability to test the stability of the hydrogen peroxide. He shall certify to the master that the cargo has been loaded in a stable condition. 15.5.2.11 Protective clothing that is resistant to hydrogen peroxide shall be provided for each crew member involved in cargo-transfer operations.

Cargo hoses used for transfer of hydrogen peroxide shall be marked �FOR HYDROGEN PEROXIDE TRANSFER ONLY�. 15.5.3 Procedures for inspection, cleaning, passivation and loading of tanks for the carriage of

hydrogen peroxide solutions 8-60%, which have contained other cargoes, or for the carriage of other cargoes after the carriage of hydrogen peroxide

15.5.3.1 Tanks having contained cargoes other than hydrogen peroxide shall be inspected, cleaned and passivated before re-use for the transport of hydrogen peroxide solutions. The procedures for inspection and cleaning, as given in paragraphs 15.5.3.2 to 15.5.3.8 below, apply to both stainless steel and pure aluminium tanks (see paragraph 15.5.2.2). Procedures for passivation are given in paragraph 15.5.3.9 for stainless steel and 15.5.3.10 for aluminium. Unless otherwise specified, all steps apply to the tanks and to all associated equipment having been in contact with the other cargo. 15.5.3.2 After unloading the previous cargo the tank shall be rendered safe and inspected for any residues, scale and rust. 15.5.3.3 Tanks and associated equipment shall be washed with clean filtered water. The water to be used shall at least have the quality of potable water with a low chlorine content. 15.5.3.4 Trace residues and vapours of the previous cargo shall be removed by steaming of tank and equipment. 15.5.3.5 Tank and equipment are washed again with clean water (quality as above) and dried, using filtered, oil-free air. 15.5.3.6 The atmosphere in the tank shall be sampled and investigated for the presence of organic vapours and oxygen concentration. 15.5.3.7 The tank shall be checked again by visual inspection for residues of the previous cargo, scale and rust as well as for any smell of the previous cargo. 15.5.3.8 If inspection or measurements indicate the presence of residues of the previous cargo or its vapours, actions described in paragraphs 15.5.3.3 to 15.5.3.5 shall be repeated. 15.5.3.9 Tank and equipment made from stainless steel which have contained other cargoes than hydrogen peroxide or which have been under repair shall be cleaned and passivated, regardless of any previous passivation, according to the following procedure:



.1 New welds and other repaired parts shall be cleaned and finished using stainless

steel wire brush, chisel, sandpaper or buff. Rough surfaces shall be given a smooth finish. A final polishing is necessary.

.2 Fatty and oily residues shall be removed by the use of appropriate organic

solvents or detergent solutions in water. The use of chlorine-containing compounds shall be avoided as they can seriously interfere with passivation.

.3 The residues of the degreasing agent shall be removed, followed by a washing

with water. .4 In the next step, scale and rust shall be removed by the application of acid (e.g. a

mixture of nitric and hydrofluoric acids), followed again by a washing with clean water.

.5 All the metal surfaces which can come into contact with hydrogen peroxide shall

be passivated by the application of nitric acid of a concentration between 10 and 35% by mass. The nitric acid must be free from heavy metals, other oxidizing agents or hydrogen fluoride. The passivation process shall continue for 8 to 24 h, depending upon the concentration of acid, the ambient temperature and other factors. During this time a continuous contact between the surfaces to be passivated and the nitric acid shall be ensured. In the case of large surfaces this may be achieved by recirculating the acid. Hydrogen gas may be evolved in the passivation process, leading to the presence of an explosive atmosphere in the tanks. Therefore, appropriate measures must be taken to avoid the build-up or the ignition of such an atmosphere.

.6 After passivation the surfaces shall be thoroughly washed with clean filtered

water. The washing process shall be repeated until the effluent water has the same pH value as the incoming water.

.7 Surfaces treated according to the above steps may cause some decomposition

when coming into contact with hydrogen peroxide for the first time. This decomposition will cease after a short time (usually within two or three days). Therefore an additional flushing with hydrogen peroxide for a period of at least two days is recommended.

.8 Only degreasing agents and acid cleaning agents which have been recommended

for this purpose by the manufacturer of the hydrogen peroxide shall be used in the process.

15.5.3.10 Tanks and equipment made from aluminium and which have contained cargoes other than hydrogen peroxide, or which have been under repair, shall be cleaned and passivated. The following is an example of a recommended procedure: .1 The tank shall be washed with a solution of a sulphonated detergent in hot water,

followed by a washing with water.


Page 61


.2 The surface shall then be treated for 15 to 20 min with a solution of sodium

hydroxide of a concentration of 7% by mass or treated for a longer period with a less concentrated solution (e.g. for 12 h with 0.4 to 0.5% sodium hydroxide). To prevent excessive corrosion at the bottom of the tank when treating with more concentrated solutions of sodium hydroxide, water shall be added continuously to dilute the sodium hydroxide solution which collects there.

.3 The tank shall be thoroughly washed with clean, filtered water. As soon as

possible after washing, the surface shall be passivated by the application of nitric acid of a concentration between 30 and 35% by mass. The passivation process shall continue for 16 to 24 h. During this time a continuous contact between the surfaces to be passivated and the nitric acid shall be ensured.

.4 After passivation the surfaces shall be thoroughly washed with clean, filtered

water. The washing process shall be repeated until the effluent water has the same pH value as the incoming water.

.5 A visual inspection shall be made to ensure that all surfaces have been treated. It

is recommended that an additional flushing is carried out for a minimum of 24 h with dilute hydrogen peroxide solution of a concentration approximately 3% by mass.

15.5.3.11 The concentration and stability of the hydrogen peroxide solution to be loaded shall be determined. 15.5.3.12 The hydrogen peroxide is loaded under intermittent visual supervision of the interior of the tank from an appropriate opening. 15.5.3.13 If substantial bubbling is observed which does not disappear within 15 min after the completion of loading, the contents of the tank shall be unloaded and disposed of in an environmentally safe manner. The tank and equipment shall then be repassivated as described above. 15.5.3.14 The concentration and stability of the hydrogen peroxide solution shall be determined again. If the same values are obtained within the limits of error as in paragraph 15.5.3.10, the tank is considered to be properly passivated and the cargo ready for shipment. 15.5.3.15 Actions described in paragraphs 15.5.3.2 to 15.5.3.8 shall be carried out under the supervision of the master or shipper. Actions described in paragraphs 15.5.3.9 to 15.5.3.15 shall be carried out under the on-site supervision and responsibility of a representative of the hydrogen peroxide manufacturer or under supervision and responsibility of another person familiar with the safety-relevant properties of hydrogen peroxide. 15.5.3.16 The following procedure shall be applied when tanks having contained hydrogen peroxide solution are to be used for other products (unless otherwise specified, all steps apply to the tanks and to all associated equipment having been in contact with hydrogen peroxide): .1 Hydrogen peroxide cargo residue shall be drained as completely as possible from

tanks and equipment.



.2 Tanks and equipment shall be rinsed with clean water, and subsequently

thoroughly washed with clean water. .3 The interior of the tank shall be dried and inspected for any residues. Steps .1 to .3, in 15.5.3.16, shall be carried out under the supervision of the master or the shipper. Step .3 in paragraph 15.5.3.16 shall be carried out by a person familiar with the safety-relevant properties of the chemical to be transported and of hydrogen peroxide. SPECIAL CAUTIONS : 1 Hydrogen peroxide decomposition may enrich the

atmosphere with oxygen and appropriate precautions shall be observed.

2 Hydrogen gas may be evolved in the passivation processes

described in paragraphs 15.5.3.9.5, 15.5.3.10.2 and 15.5.3.10.4, leading to the presence of an explosive atmosphere in the tank. Therefore, appropriate measures must be taken to avoid the build-up or the ignition of such an atmosphere.

15.6 Motor fuel anti-knock compounds (containing lead alkyls) 15.6.1 Tanks used for these cargoes shall not be used for the transportation of any other cargo except those commodities to be used in the manufacture of motor fuel anti-knock compounds containing lead alkyls. 15.6.2 If a cargo pump-room is located on deck level according to 15.18, the ventilation arrangements shall be in compliance with 15.17. 15.6.3 Entry into cargo tanks used for the transportation of these cargoes is not permitted unless approved by the Administration. 15.6.4 Air analysis shall be made for lead content to determine if the atmosphere is satisfactory prior to allowing personnel to enter the cargo pump-room or void spaces surrounding the cargo tank. 15.7 Phosphorus, yellow or white 15.7.1 Phosphorus shall, at all times, be loaded, carried and discharged under a water pad of 760 mm minimum depth. During discharge operations, arrangements shall be made to ensure that water occupies the volume of phosphorus discharged. Any water discharged from a phosphorus tank shall be returned only to a shore installation. 15.7.2 Tanks shall be designed and tested to a minimum equivalent water head of 2.4 m above the top of the tank, under designed loading conditions, taking into account the depth, relative density and method of loading and discharge of the phosphorus. 15.7.3 Tanks shall be so designed as to minimize the interfacial area between the liquid phosphorus and its water pad.

The system shall operate automatically in the event of an escape of phosphorus. 15.7.9 Void spaces referred to in 15.7.8 shall be provided with effective means of mechanical ventilation which shall be capable of being sealed off quickly in an emergency. 15.7.10 Loading and discharge of phosphorus shall be governed by a central system on the ship which, in addition to incorporating high-level alarms, shall ensure that no overflow of tanks is possible and that such operations can be stopped quickly in an emergency from either ship or shore. 15.7.11 During cargo transfer, a water hose on deck shall be connected to a water supply and kept flowing throughout the operation so that any spillage of phosphorus may be washed down with water immediately. 15.7.12 Ship-to-shore loading and discharge connections shall be of a type approved by the Administration. 15.8 Propylene oxide or ethylene oxide/propylene oxide mixtures with an ethylene oxide

content of not more than 30% by mass 15.8.1 Products transported under the provisions of this section shall be acetylene-free. 15.8.2 Unless cargo tanks are properly cleaned, these products shall not be carried in tanks which have contained as one of the three previous cargoes any products known to catalyse polymerization, such as: .1 mineral acids (e.g. sulphuric, hydrochloric, nitric); .2 carboxylic acids and anhydrides (e.g. formic, acetic); .3 halogenated carboxylic acids (e.g. chloracetic); .4 sulphonic acids (e.g. benzenesulphonic); .5 caustic alkalis (e.g. sodium hydroxide, potassium hydroxide);



.6 ammonia and ammonia solutions; .7 amines and amine solutions; and .8 oxidizing substances. 15.8.3 Before loading, tanks shall be thoroughly and effectively cleaned, to remove all traces of previous cargoes from tanks and associated pipework, except where the immediately prior cargo has been propylene oxide or ethylene oxide/propylene oxide mixtures. Particular care shall be taken in the case of ammonia in tanks made of steel other than stainless steel. 15.8.4 In all cases, the effectiveness of cleaning procedures for tanks and associated pipework shall be checked by suitable testing or inspection, to ascertain that no traces of acidic or alkaline materials remain that might create a hazardous situation in the presence of these products. 15.8.5 Tanks shall be entered and inspected prior to each initial loading of these products to ensure freedom from contamination, heavy rust deposits and visible structural defects. When cargo tanks are in continuous service for these products, such inspections shall be performed at intervals of not more than two years. 15.8.6 Tanks for the carriage of these products shall be of steel or stainless steel construction. 15.8.7 Tanks for the carriage of these products may be used for other cargoes after thorough cleaning of tanks and associated pipework systems by washing or purging. 15.8.8 All valves, flanges, fittings and accessory equipment shall be of a type suitable for use with the products and shall be constructed of steel or stainless steel in accordance with recognized standards.

If vapour return to shore is used during tank loading, the vapour-return system connected to a containment system for the product shall be independent of all other containment systems. 15.8.14.3 During discharge operations, the pressure in the cargo tank must be maintained above 0.007 MPa gauge. 15.8.15 The cargo may be discharged only by deepwell pumps, hydraulically operated submerged pumps, or inert-gas displacement. Each cargo pump shall be arranged to ensure that the product does not heat significantly if the discharge line from the pump is shut off or otherwise blocked. 15.8.16 Tanks carrying these products shall be vented independently of tanks carrying other products. Facilities shall be provided for sampling the tank contents without opening the tank to atmosphere. 15.8.17 Cargo hoses used for transfer of these products shall be marked �FOR ALKYLENE OXIDE TRANSFER ONLY�. 15.8.18 Cargo tanks, void spaces and other enclosed spaces adjacent to an integral gravity cargo tank carrying propylene oxide shall either contain a compatible cargo (those cargoes specified in 15.8.2 are examples of substances considered incompatible) or be inerted by injection of a suitable inert gas. Any hold space in which an independent cargo tank is located shall be inerted. Such inerted spaces and tanks shall be monitored for these products and oxygen. The oxygen content of these spaces shall be maintained below 2%. Portable sampling equipment is satisfactory. 15.8.19 In no case shall air be allowed to enter the cargo pump or piping system while these products are contained within the system. 15.8.20 Prior to disconnecting shore-lines, the pressure in liquid and vapour lines shall be relieved through suitable valves installed at the loading header. Liquid and vapour from these lines shall not be discharged to atmosphere. 15.8.21 Propylene oxide may be carried in pressure tanks or in independent or integral gravity tanks.

An alarm shall be provided to indicate malfunctioning of the temperature controls. The capacity of each cooling system shall be sufficient to maintain the temperature of the liquid cargo below the reference temperature of the system. 15.8.23.2 An alternative arrangement may consist of three cooling plants, any two of which shall be sufficient to maintain the liquid temperature below the reference temperature. 15.8.23.3 Cooling media which are separated from the products by a single wall only shall be nonreactive with the products. 15.8.23.4 Cooling systems requiring compression of the products shall not be used. 15.8.24 Pressure-relief-valve settings shall not be less than 0.02 MPa gauge and for pressure tanks not greater than 0.7 MPa gauge for the carriage of propylene oxide and not greater than 0.53 MPa gauge for the carriage of propylene oxide/ethylene oxide mixtures. 15.8.25.1 The piping system for tanks to be loaded with these products shall be separated (as defined in 3.1.4) from piping systems for all other tanks, including empty tanks. If the piping system for the tanks to be loaded is not independent (as defined in 1.3.18), the required piping separation shall be accomplished by the removal of spool-pieces, valves, or other pipe section and the installation of blank flanges at these locations. The required separation applies to all liquid and vapour piping, liquid and vapour vent lines and any other possible connections, such as common inert-gas supply lines. 15.8.25.2 These products may be transported only in accordance with cargo-handling plans that have been approved by the Administration. Each intended loading arrangement shall be shown on a separate cargo-handling plan. Cargo-handling plans shall show the entire cargo piping system and the locations for installation of blank flanges needed to meet the above piping separation requirements. A copy of each approved cargo-handling plan shall be maintained on board the ship.

L

RL V98.0V

ρρ

=

Where VL = maximum volume to which the tank may be loaded V = volume of the tank Rρ = density of cargo at the reference temperature Lρ = density of cargo at the loading temperature and pressure 15.8.26.3 The maximum allowable tank filling limits for each cargo tank shall be indicated for each loading temperature which may be applied and for the applicable maximum reference temperature, on a list to be approved by the Administration. A copy of the list shall be permanently kept on board by the master. 15.8.27 The cargo shall be carried under a suitable protective padding of nitrogen gas. An automatic nitrogen make-up system shall be installed to prevent the tank pressure falling below 0.007 MPa gauge in the event of product temperature fall due to ambient conditions or maloperation of refrigeration systems. Sufficient nitrogen shall be available on board to satisfy the demand of the automatic pressure control. Nitrogen of commercially pure quality (99.9% by volume) shall be used for padding. A battery of nitrogen bottles connected to the cargo tanks through a pressure-reduction valve satisfies the intention of the expression �automatic� in this context. 15.8.28 The cargo tank vapour space shall be tested prior to and after loading to ensure that the oxygen content is 2% by volume or less. 15.8.29 A water-spray system of sufficient capacity shall be provided to blanket effectively the area surrounding the loading manifold, the exposed deck piping associated with product handling, and the tank domes. The arrangement of piping and nozzles shall be such as to give a uniform distribution rate of 10 l/m2/min. Remote manual operation shall be arranged such that remote starting of pumps supplying the water-spray system and remote operation of any normally closed valves in the system can be carried out from a suitable location outside the cargo area, adjacent to the accommodation spaces and readily accessible and operable in the event of fire in the areas protected. The water-spray system shall be capable of both local and remote manual operation, and the arrangement shall ensure that any spilled cargo is washed away. Additionally, a water hose with pressure to the nozzle, when atmospheric temperatures permit, shall be connected ready for immediate use during loading and unloading operations. 15.8.30 A remotely operated, controlled closing-rate, shutoff valve shall be provided at each cargo-hose connection used during cargo transfer.

15.11.6 Substances subjected to the requirements of this section shall be segregated from oil fuel tanks, in addition to the segregation requirements in 3.1.1. 15.11.7 Provision shall be made for suitable apparatus to detect leakage of cargo into adjacent spaces. 15.11.8 The cargo pump-room bilge pumping and drainage arrangements shall be of corrosion-resistant materials. 15.12 Toxic products 15.12.1 Exhaust openings of tank vent systems shall be located: .1 at a height of B/3 or 6 m, whichever is greater, above the weather deck or, in the

case of a deck tank, the access gangway; .2 not less than 6 m above the fore-and-aft gangway, if fitted within 6 m of the

gangway; .3 15 m from any opening or air intake to any accommodation and service spaces;

and .4 the vent height may be reduced to 3 m above the deck or fore-and-aft gangway, as

applicable, provided high-velocity vent valves of an approved type, directing the vapour/air mixture upwards in an unimpeded jet with an exit velocity of at least 30 m/s, are fitted.

15.12.2 Tank venting systems shall be provided with a connection for a vapour-return line to the shore installation. 15.12.3 Products shall: .1 not be stowed adjacent to oil fuel tanks; .2 have separate piping systems; and .3 have tank vent systems separate from tanks containing non-toxic products. 15.12.4 Cargo tank relief-valve settings shall be a minimum of 0.02 MPa gauge. 15.13 Cargoes protected by additives 15.13.1 Certain cargoes with a reference in column o in the table of chapter 17, by the nature of their chemical make-up, tend, under certain conditions of temperature, exposure to air or contact with a catalyst, to undergo polymerization, decomposition, oxidation or other chemical changes. Mitigation of this tendency is carried out by introducing small amounts of chemical additives into the liquid cargo or controlling the cargo tank environment.



15.13.2 Ships carrying these cargoes shall be so designed as to eliminate from the cargo tanks and cargo-handling system any material of construction or contaminants which could act as a catalyst or destroy the inhibitor. 15.13.3 Care shall be taken to ensure that these cargoes are sufficiently protected to prevent deleterious chemical change at all times during the voyage. Ships carrying such cargoes shall be provided with a certificate of protection from the manufacturer, and kept during the voyage, specifying: .1 the name and amount of additive present; .2 whether the additive is oxygen-dependent; .3 date additive was put in the product and duration of effectiveness; .4 any temperature limitations qualifying the additives' effective lifetime; and .5 the action to be taken shall the length of voyage exceed the effective lifetime of

the additives. 15.13.4 Ships using the exclusion of air as the method of preventing oxidation of the cargo shall comply with 9.1.3. 15.13.5 A product containing an oxygen-dependent additive shall be carried without inertion (in tanks of a size not greater than 3,000 m3). Such cargoes shall not be carried in a tank requiring inertion under the requirements of SOLAS chapter II-2*. 15.13.6 Venting systems shall be of a design that eliminates blockage from polymer build-up. Venting equipment shall be of a type that can be checked periodically for adequacy of operation. 15.13.7 Crystallization or solidification of cargoes normally carried in the molten state can lead to depletion of inhibitor in parts of the tank's contents. Subsequent remelting can thus yield pockets of uninhibited liquid, with the accompanying risk of dangerous polymerization. To prevent this, care shall be taken to ensure that at no time are such cargoes allowed to crystallize or solidify, either wholly or partially, in any part of the tank. Any required heating arrangements shall be such as to ensure that in no part of the tank does cargo become overheated to such an extent that any dangerous polymerization can be initiated. If the temperature from steam coils would induce overheating, an indirect low-temperature heating system shall be used. 15.14 Cargoes with a vapour pressure greater than 0.1013 MPa absolute at 37.8°C 15.14.1 For a cargo referenced in column o in the table of chapter 17 to this section, a mechanical refrigeration system shall be provided unless the cargo system is designed to withstand the vapour pressure of the cargo at 45°C. Where the cargo system is designed to withstand the vapour pressure of the cargo at 45°C, and no refrigeration system is provided, a notation shall be made in the conditions of carriage on the International Certificate of Fitness for the Carriage of Dangerous Chemicals in Bulk to indicate the required relief-valve setting for the tanks. * For equivalency arrangements for the carriage of styrene monomer, see MSC/Circ.879 and

MSC/Circ.879/Corr.1


Page 71


15.14.2 A mechanical refrigeration system shall maintain the liquid temperature below the boiling temperature at the cargo tank design pressure. 15.14.3 When ships operate in restricted areas and at restricted times of the year, or on voyages of limited duration, the Administration involved may agree to waive requirements for a refrigeration system. A notation of any such agreement, listing geographic area restrictions and times of the year, or voyage duration limitations, shall be included in the conditions of carriage on the International Certificate of Fitness for the Carriage of Dangerous Chemicals in Bulk. 15.14.4 Connections shall be provided for returning expelled gases to shore during loading. 15.14.5 Each tank shall be provided with a pressure gauge which indicates the pressure in the vapour space above the cargo. 15.14.6 Where the cargo needs to be cooled, thermometers shall be provided at the top and bottom of each tank. 15.14.7.1 No cargo tanks shall be more than 98% liquid-full at the reference temperature (R). 15.14.7.2 The maximum volume (VL) of cargo to be loaded in a tank shall be:

L

RL V98.0V

ρρ

=

Where V = volume of the tank Rρ = density of cargo at the reference temperature (R)

Lρ = density of cargo at the loading temperature 15.14.7.3 The maximum allowable tank filling limits for each cargo tank shall be indicated for each loading temperature which may be applied, and for the applicable maximum reference temperature, on a list approved by the Administration. A copy of the list shall be permanently kept on board by the master. 15.15 Cargoes with low ignition temperature and wide flammability range Deleted. 15.16 Cargo contamination 15.16.1 Deleted. 15.16.2 Where column o in the table of chapter 17 refers to this section, water shall not be allowed to contaminate this cargo. In addition, the following provisions apply: .1 Air inlets to pressure/vacuum-relief valves of tanks containing the cargo shall be

situated at least 2 m above the weather deck.



.2 Water or steam shall not be used as the heat-transfer media in a cargo temperature

control system required by chapter 7. .3 The cargo shall not be carried in cargo tanks adjacent to permanent ballast or

water tanks unless the tanks are empty and dry. .4 The cargo shall not be carried in tanks adjacent to slop tanks or cargo tanks

containing ballast or slops or other cargoes containing water which may react in a dangerous manner. Pumps, pipes or vent lines serving such tanks shall be separate from similar equipment serving tanks containing the cargo. Pipelines from slop tanks or ballast lines shall not pass through tanks containing the cargo unless encased in a tunnel.

15.17 Increased ventilation requirements For certain products, the ventilation system as described in 12.1.3 shall have a minimum capacity of at least 45 changes of air per hour, based upon the total volume of space. The ventilation system exhaust ducts shall discharge at least 10 m away from openings into accommodation spaces, work areas or other similar spaces, and intakes to ventilation systems, and at least 4 m above the tank deck. 15.18 Special cargo pump-room requirements For certain products, the cargo pump-room shall be located on the deck level or cargo pumps shall be located in the cargo tank. The Administration may give special consideration to cargo pump-rooms below deck. 15.19 Overflow control 15.19.1 The provisions of this section are applicable where specific reference is made in column o in the table of chapter 17, and are in addition to the requirements for gauging devices. 15.19.2 In the event of a power failure on any system essential for safe loading, an alarm shall be given to the operators concerned. 15.19.3 Loading operations shall be terminated at once in the event of any system essential for safe loading becoming inoperative. 15.19.4 Level alarms shall be capable of being tested prior to loading. 15.19.5 The high-level alarm system required under 15.19.6 shall be independent of the overflow-control system required by 15.19.7 and shall be independent of the equipment required by 13.1. 15.19.6 Cargo tanks shall be fitted with a visual and audible high-level alarm which complies with 15.19.1 to 15.19.5 and which indicates when the liquid level in the cargo tank approaches the normal full condition.


Page 73


15.19.7 A tank overflow-control system required by this section shall: .1 come into operation when the normal tank loading procedures fail to stop the tank

liquid level exceeding the normal full condition; .2 give a visual and audible tank-overflow alarm to the ship's operator; and .3 provide an agreed signal for sequential shutdown of onshore pumps or valves or

both and of the ship's valves. The signal, as well as the pump and valve shutdown, may be dependent on operator's intervention. The use of shipboard automatic closing valves shall be permitted only when specific approval has been obtained from the Administration and the port State authority concerned.

15.19.8 The loading rate (LR) of the tank shall not exceed:

)h/m(t

U3600LR 3=

where U = ullage volume (m3) at operating signal level; t = time(s) needed from the initiating signal to fully stopping the cargo flow into the

tank, being the sum of times needed for each step in sequential operations such as operator's responses to signals, stopping pumps and closing valves;

and shall also take into account the pipeline system design pressure. 15.20 Alkyl (C7-C9) nitrates, all isomers 15.20.1 The carriage temperature of the cargo shall be maintained below 100°C to prevent the occurrence of a self-sustaining, exothermic decomposition reaction. 15.20.2 The cargo may not be carried in independent pressure vessels permanently affixed to the vessel's deck unless: .1 the tanks are sufficiently insulated from fire; and .2 the vessel has a water deluge system for the tanks such that the cargo temperature

is maintained below 100°C and the temperature rise in the tanks does not exceed 1.5°C per hour for a fire of 650°C.

15.21 Temperature sensors Temperature sensors shall be used to monitor the cargo pump temperature to detect overheating due to pump failures.

a If the product to be carried contains flammable solvents such that the flashpoint does not

exceed 60°C, then special electrical systems and a flammable-vapour detector shall be provided.

b Although water is suitable for extinguishing open-air fires involving chemicals to which

this footnote applies, water shall not be allowed to contaminate closed tanks containing these chemicals because of the risk of hazardous gas generation.

c Phosphorus, yellow or white is carried above its autoignition temperature and therefore

flashpoint is not appropriate. Electrical equipment requirements may be similar to those for substances with a flashpoint above 60°C.

d Requirements are based on those isomers having a flashpoint of 60°C, or less; some

isomers have a flashpoint greater than 60°C, and therefore the requirements based on flammability would not apply to such isomers.

e Applies to n-decyl alcohol only. f Dry chemical shall not be used as fire extinguishing media. g Confined spaces shall be tested for both formic acid vapours and carbon monoxide gas,

a decomposition product. h Applies to p-xylene only. i For mixtures containing no other components with safety hazards and where the pollution

category is Y or less j only certain alcohol-resistant foams are effective k Requirements for Ship Type identified in column e might be subject to regulation 4.1.3 of

Annex II of MARPOL 73/78 l Applicable when the melting point is equal to or greater than 0°C.

Chapter 18

List of products to which the Code does not apply

18.1 The following are products, which have been reviewed for their safety and pollution hazards and determined not to present hazards to such an extent as to warrant application of the Code. 18.2 Although the products listed in this chapter fall outside the scope of the Code, the attention of Administrations is drawn to the fact that some safety precautions may be needed for their safe transportation. Accordingly, Administrations shall prescribe appropriate safety requirements. 18.3 Some liquid substances are identified as falling into Pollution Category Z and, therefore, subject to certain requirements of Annex II of MARPOL 73/78. 18.4 Liquid mixtures which are assessed or provisionally assessed under regulation 6.3 of MARPOL Annex II as falling into Pollution Category Z or OS, and which do not present safety hazards, may be carried under the appropriate entry in this chapter for �Noxious or Non-Noxious Liquid Substances, not otherwise specified (n.o.s.)�. EXPLANATORY NOTES Product name

The product name shall be used in the shipping document for any cargo offered for bulk shipments. Any additional name may be included in brackets after the product name. In some cases, the product names are not identical with the names given in previous issues of the Code.

Pollution Category

The letter Z means the Pollution Category assigned to each product under Annex II of MARPOL 73/78. OS means the product was evaluated and found to fall outside Categories X, Y, or Z.

Index of Products Carried in Bulk

19.1 The first column of the Index of Products Carried in Bulk (hereafter referred to as �the Index�) provides the so called Index Name. Where the Index Name is in capital and in bold, the Index Name is identical to the Product Name in either chapter 17 or chapter 18. The second column listing the relevant Product Name is therefore empty. Where the Index Name is in non-bold lower case it reflects a synonym for which the Product Name in either chapter 17 or chapter 18 is given in the second column. The relevant chapter of the IBC Code is reflected in the third column. The fourth column gives the UN Numbers of products, which were available up to February 2001.* 19.2 The Index has been developed for information purposes only. None of the Index Names indicated in non-bold lower case in the first column shall be used as Product Name on the shipping document. 19.3 Prefixes forming an integral part of the name are shown in ordinary (roman) type and are taken into account in determining the alphabetical order of entries. These include such prefixes as: Mono Di Tri Tetra Penta Iso Bis Neo Ortho Cyclo 19.4 Prefixes that are disregarded for purposes of alphabetical order are in italics and include the following: n- (normal-) sec- (secondary-) tert- (tertiary-) o- (ortho-) m- (meta-) p- (para-) N- O- sym- (symmetrical) uns- (unsymmetrical) dl- cis- trans- (E)- (Z)- alpha- (α-) beta- (β-) gamma- (γ-) epsilon- (ε-) [Note: The following pages 104 to 143 are not numbered as they were database-generated.] * The reason for this decision is given in paragraph 7.10 of BLG 6/16.

Chapter 20

Transport of liquid chemical wastes 20.1 Preamble 20.1.1 Maritime transport of liquid chemical wastes could present a threat to human health and to the environment. 20.1.2 Liquid chemical wastes shall, therefore, be transported in accordance with relevant international conventions and recommendations and, in particular, where it concerns maritime transport in bulk, with the requirements of this Code. 20.2 Definitions For the purpose of this chapter: 20.2.1 Liquid chemical wastes are substances, solutions or mixtures, offered for shipment, containing or contaminated with one or more constituents which are subject to the requirements of this Code and for which no direct use is envisaged but which are carried for dumping, incineration or other methods of disposal other than at sea. 20.2.2 Transboundary movement means maritime transport of wastes from an area under the national jurisdiction of one country to or through an area under the national jurisdiction of another country, or to or through an area not under the national jurisdiction of any country, provided at least two countries are concerned by the movement. 20.3 Applicability 20.3.1 The requirements of this chapter are applicable to the transboundary movement of liquid chemical wastes in bulk by seagoing ships and shall be considered in conjunction with all other requirements of this Code. 20.3.2 The requirements of this chapter do not apply to:

.1 wastes derived from shipboard operations which are covered by the requirements of MARPOL 73/78; and

.2 substances, solutions or mixtures containing or contaminated with radioactive

materials which are subject to the applicable requirements for radioactive materials.

20.4 Permitted shipments 20.4.1 Transboundary movement of wastes is permitted to commence only when:

.1 notification has been sent by the competent authority of the country of origin, or by the generator or exporter through the channel of the competent authority of the country of origin, to the country of final destination; and


Page 145


.2 the competent authority of the country of origin, having received the written

consent of the country of final destination stating that the wastes will be safely incinerated or treated by other methods of disposal, has given authorization to the movement.

20.5 Documentation 20.5.1 In addition to the documentation specified in 16.2 of this Code, ships engaged in transboundary movement of liquid chemical wastes shall carry on board a waste movement document issued by the competent authority of the country of origin. 20.6 Classification of liquid chemical wastes 20.6.1 For the purpose of the protection of the marine environment, all liquid chemical wastes transported in bulk shall be treated as Category X noxious liquid substances, irrespective of the actual evaluated category. 20.7 Carriage and handling of liquid chemical wastes 20.7.1 Liquid chemical wastes shall be carried in ships and cargo tanks in accordance with the minimum requirements for liquid chemical wastes specified in chapter 17, unless there are clear grounds indicating that the hazards of the wastes would warrant:

.1 carriage in accordance with the ship type 1 requirements; or

.2 any additional requirements of this Code applicable to the substance or, in case the of a mixture, its constituent presenting the predominant hazard.



Chapter 21

Criteria for assigning carriage requirements for products subject to the IBC Code

21.1 Introduction 21.1.1 The following criteria are guidelines for the determination of pollution classification and assignment of appropriate carriage requirements for bulk liquid cargoes being considered as candidates for entry into the IBC Code or annexes 1, 3 or 4 of MEPC.2/Circs. 21.1.2 In developing such criteria, every effort has been made to follow the criteria and cut off points developed under the Global Harmonized System (GHS). 21.1.3 Although the criteria are intended to be closely defined in order to establish a uniform approach, it must be emphasized that these are guidelines only and, where human experience or other factors indicates the need for alternative arrangements, these shall always be taken into account. Where deviations from the criteria have been recognized, they shall be properly recorded with justifications. 21.2 Contents 21.2.1 This chapter contains the following: .1 minimum safety and pollution criteria for products subject to chapter 17 of the

IBC Code; .2 criteria used to assign the minimum carriage requirements for products, which

meet the safety or pollution criteria to make them subject to chapter 17 of the IBC Code;

.3 criteria used for special requirements in chapter 15 of the IBC Code to be included

in column o of chapter 17 of the IBC Code; .4 criteria used for special requirements in chapter 16 of the IBC Code to be included

in column o of chapter 17 of the IBC Code; and .5 definitions of properties used within this chapter. 21.3 Minimum safety and pollution criteria for products subject to chapter 17 of the

IBC Code 21.3.1 Products are deemed to be hazardous and subject to chapter 17 of the IBC Code if they meet one or more of the following criteria:

.1 inhalation LC50 <20 mg/l/4 h (see definitions in paragraph 21.7.1.1);

.2 dermal LD50 <2000 mg/kg (see definitions in paragraph 21.7.1.2);

.3 oral LD50 <2000 mg/kg (see definitions in paragraph 21.7.1.3);


Page 147


.4 toxic to mammals by prolonged exposure (see definitions in paragraph 21.7.2);

.5 cause skin sensitization (see definitions in paragraph 21.7.3); .6 cause respiratory sensitization (see definitions in paragraph 21.7.4);

.7 corrosive to skin (see definitions in paragraph 21.7.5);

.8 have a Water Reactive Index (WRI) of >1 (see definitions in paragraph 21.7.6);

.9 require inertion, inhibition, stabilization, temperature control or tank environmental control in order to prevent a hazardous reaction (see definitions in paragraph 21.7.10);

.10 flash point <23°C; and have an explosive/flammability range (expressed as a

percentage by volume in air) of >20%;

.11 autoignition temperature of <200°C; and

.12 classified as pollution category X or Y or meeting the criteria for rules 11 to 13 under paragraph 21.4.5.1.

* All inhalation toxicity data are assumed to be associated with vapours and not mists or sprays, unless

indicated otherwise.



21.7.2 Toxic to mammals by prolonged exposure 21.7.2.1 A product is classified as toxic by prolonged exposure if it meets any of the following criteria: it is known to be, or suspected of being a carcinogen, mutagen, reprotoxic, neurotoxic, immunotoxic or exposure below the lethal dose is known to cause specific organ oriented systemic toxicity (TOST) or other related effects. 21.7.2.2 Such effects may be identified from the GESAMP Hazard Profile of the product or other recognized sources of such information. 21.7.3 Skin sensitization 21.7.3.1 A product is classified as a skin sensitizer:

.1 if there is evidence in humans that the substance can induce sensitization by skin contact in a substantial number of persons; or

.2 where there are positive results from an appropriate animal test.

21.7.3.2 When an adjuvant type test method for skin sensitization is used, a response of at least 30% of the animals is considered as positive. For a non-adjuvant test method a response of at least 15% of the animals is considered positive. 21.7.3.3 When a positive result is obtained from the Mouse Ear Swelling Test (MEST) or the Local Lymph Node Assay (LLNA), this may be sufficient to classify the product as a skin sensitizer. 21.7.4 Respiratory sensitization 21.7.4.1 A product is classified as a respiratory sensitizer:

.1 if there is evidence in humans that the substance can induce specific respiratory hypersensitivity; and/or

.2 where there are positive results from an appropriate animal test; and/or

.3 where the product is identified as a skin sensitizer and there is no evidence to

show that it is not a respiratory sensitizer. 21.7.5 Corrosive to skin*

Observation time

Severely corrosive to skin < 3 min <1 h Highly corrosive to skin > 3 min - < 1 h <14 days Moderately corrosive to skin > 1 h - < 4 h <14 days

* Products that are corrosive to skin are, for the purpose of assigning relevant carriage requirements, deemed

to be corrosive by inhalation.


Page 157


21.7.6 Water reactive substances 21.7.6.1 These are classified into three groups as follows:

Water reactive index (WRI)

Definition

2 Any chemical which, in contact with water, may produce a toxic, flammable or corrosive gas or aerosol.

1 Any chemical which, in contact with water, may generate heat or produce a non-toxic, non-flammable or non corrosive gas.

0 Any chemical which, in contact with water, would not undergo a reaction to justify a value of 1 or 2.

21.7.7 Air reactive substances 21.7.7.1 Air reactive substances are products which react with air to cause a potentially hazardous situation, e.g. the formation of peroxides which may cause an explosive reaction. 21.7.8 Electrical apparatus - Temperature Class (for products which either have a flashpoint of <60oC or are heated to within 15°C of their flashpoint) 21.7.8.1 The Temperature Class is defined by the International Electrotechnical Commission (IEC) as:

The highest temperature attained under practical conditions of operation within the rating of the apparatus (and recognized overloads, if any, associated therewith) by any part of any surface, the exposure of which to an explosive atmosphere may involve a risk.

21.7.8.2 The Temperature Class of the electrical apparatus is assigned by selecting the Maximum Surface Temperature which is closest to, but less than, the product's autoignition temperature (see 21.4.9.1.1). 21.7.9 Electrical apparatus - Apparatus group (for products with a flashpoint of <60oC) 21.7.9.1 This refers to intrinsically safe and associated electrical apparatus for explosive gas atmospheres which the IEC divide into the following groups:

Group I: for mines susceptible to firedamp (not used by IMO); and Group II: for applications in other industries - further sub-divided according to its

Maximum Experimental Safe Gap (MESG) and/or the Minimum Igniting Current (MIC) of the gas/vapour into groups IIA, IIB and IIC.

21.7.9.2 This property cannot be determined from other data associated with the product; it has to be either measured or assigned by assimilation with related products in an homologous series.



21.7.10 Special carriage control conditions 21.7.10.1 Special carriage control conditions refer to specific measures that need to be taken in order to either prevent a hazardous reaction. They include:

.1 Inhibition: the addition of a compound (usually organic) that retards or stops an undesired chemical reaction such as corrosion, oxidation or polymerization;

.2 Stabilization: the addition of a substance (stabilizer) that tends to keep a

compound, mixture or solution from changing its form or chemical nature. Such stabilizers may retard a reaction rate, preserve a chemical equilibrium, act as antioxidants, keep pigments and other components in emulsion form or prevent the particles in colloidal suspension from precipitating;

.3 Inertion: the addition of a gas (usually nitrogen) in the ullage space of a tank

that prevents the formation of a flammable cargo/air mixture;

.4 Temperature control: the maintenance of a specific temperature range for the cargo in order to prevent a hazardous reaction or to keep the viscosity low enough to allow the product to be pumped; and

.5 Padding and venting: only applies to specific products identified on a case

by case basis. 21.7.11 Flammable cargoes 21.7.11.1 A cargo is defined as flammable according to the following criteria: IBC Code descriptor

Flash point (degrees Centigrade)

Highly flammable

< 23

Flammable

< 60 but > 23

21.7.11.2 It should be noted that flash points of mixtures and aqueous solutions need to be measured unless all of the components are non-flammable. 21.7.11.3 It should be noted that the carriage of bulk liquid cargoes which have a flash point of <60°C is subject to other SOLAS regulations.

3.3.4 Where the cargo hatch securing system does not function properly, repairs should be carried out under the supervision of the Administration. Where hatch covers or coamings undergo substantial repairs, the strength of securing devices should be upgraded to comply with annex 13.

3.3.5 For each cargo hatch cover set, at each annual survey, the following items should be surveyed:

.1 cover panels, including side plates, and stiffener attachments that may be

accessible in the open position by close-up survey (for corrosion, cracks, deformation);

.2 sealing arrangements of perimeter and cross joints (gaskets for condition

and permanent deformation, flexible seals on combination carriers, gasket lips, compression bars, drainage channels and non return valves);

.3 clamping devices, retaining bars, cleating (for wastage, adjustment, and

condition of rubber components);

.4 closed cover locating devices (for distortion and attachment);

.5 chain or rope pulleys;

.6 guides;

.7 guide rails and track wheels;

.8 stoppers;

.9 wires, chains, tensioners and gypsies;

.10 hydraulic system, electrical safety devices and interlocks; and

.11 end and interpanel hinges, pins and stools where fitted.

3.3.6 At each hatchway, at each annual survey, the coamings, with plating, stiffeners and brackets should be checked for corrosion, cracks and deformation, especially of the coaming tops.

3.3.7 Where considered necessary, the effectiveness of sealing arrangements may be proved by hose or chalk testing supplemented by dimensional measurements of seal compressing components.�

5.2.1.2 Details of the means of access should be provided in the survey planning questionnaire.

5.2.1.3 In cases where the provisions of safety and required access are judged by the attending surveyors not to be adequate, the survey of the spaces involved should not proceed.�

21 Existing paragraphs 5.2.2, 5.2.3 and 5.2.4 are replaced by the following:

�5.2.2 Cargo holds, tanks and spaces should be safe for access. Cargo holds, tanks and spaces should be gas free and properly ventilated. Prior to entering a tank, void or enclosed space, it should be verified that the atmosphere in the tank is free from hazardous gas and contains sufficient oxygen.

5.2.3 Cargo holds, tanks and spaces should be sufficiently clean and free from water, scale, dirt, oil residues, sediments etc., to reveal corrosion, deformation, fractures, damages or other structural deterioration as well as the condition of the coating. In particular this applies to areas which are subject to thickness measurement.

5.2.4 Sufficient illumination should be provided to reveal corrosion, deformation, fractures, damages or other structural deterioration as well as the condition of the coating.�


Page 11


22 The following new paragraphs 5.2.5 and 5.2.6 are added:

�5.2.5 The surveyor(s) should always be accompanied by at least one responsible person, assigned by the owner, experienced in tank and enclosed spaces inspection. In addition a backup team of at least two experienced persons should be stationed at the hatch opening of the tank or space that is being surveyed. The back-up team should continuously observe the work in the tank or space and should keep lifesaving and evacuation equipment ready for use.

5.2.6 A communication system should be arranged between the survey party in the cargo hold, tank or space being examined, the responsible officer on deck and, as the case may be, the navigation bridge. The communication arrangements should be maintained throughout the survey.�

23 In existing paragraph 5.3.2, a new sub-item �portable ladders� is inserted between the third and fourth sub-items. 24 The five sub-items in paragraph 5.3.2 are numbered from �.1� to �.5� and the five sub-items in paragraph 5.4.2 are numbered from �.1� to �.5�. 25 New paragraphs 5.4.3 to 5.4.5 are added as follows:

5.4.4 Adequate and safe lighting should be provided for the safe and efficient conduct of the survey.

5.4.5 Adequate protective clothing should be made available and used (e.g. safety helmet, gloves, safety shoes, etc.) during the survey.�

26 The existing paragraph 5.5.3 is replaced by the following:

�5.5.3 When rafts or boats will be used for close-up survey the following conditions should be observed:

.1 only rough duty, inflatable rafts or boats, having satisfactory residual

buoyancy and stability even if one chamber is ruptured, should be used; .2 the boat or raft should be tethered to the access ladder and an additional

person should be stationed down the access ladder with a clear view of the boat or raft;

.3 appropriate lifejackets should be available for all participants;

.4 the surface of water in the tank or hold should be calm (under all

foreseeable conditions the expected rise of water within the tank should not exceed 0.25 m) and the water level either stationary or falling. On no



account should the level of the water be rising while the boat or raft is in use;

.5 the tank, hold or space must contain clean ballast water only. Even a thin

sheen of oil on the water is not acceptable; and

.6 at no time should the water level be allowed to be within 1 m of the deepest under deck web face flat so that the survey team is not isolated from a direct escape route to the tank hatch. Filling to levels above the deck transverses should only be contemplated if a deck access manhole is fitted and open in the bay being examined, so that an escape route for the survey party is available at all times. Other effective means of escape to the deck may be considered.�

27 The following new paragraphs 5.5.4 to 5.5.6 are added:

�5.5.4 Rafts or boats alone may be allowed for inspection of the under deck areas for tanks or spaces, if the depth of the webs is 1.5 m or less.

5.5.5 If the depth of the webs is more than 1.5 m, rafts or boats alone may be allowed only:

.1 when the coating of the under deck structure is in GOOD condition and there is no evidence of wastage; or

.2 if a permanent means of access is provided in each bay to allow safe entry

and exit. This means of access should be direct from the deck via a vertical ladder with a small platform fitted approximately 2 m below the deck. Other effective means of escape to the deck may be considered.

If neither of the above conditions are met, then staging or other equivalent means should be provided for the survey of the under deck areas.

5.5.6 The use of rafts or boats alone in paragraphs 5.5.4 and 5.5.5 does not preclude the use of boats or rafts to move about within a tank during a survey.�

28 The following new section 5.6 is added:

�5.6 Survey planning meeting

5.6.1 The establishment of proper preparation and the close co-operation between the attending surveyor(s) and the owner�s representatives onboard prior to and during the survey are an essential part in the safe and efficient conduct of the survey. During the survey on board safety meetings should be held regularly.

5.6.2 Prior to commencement of any part of the renewal and intermediate survey, a survey planning meeting should be held between the attending surveyor(s), the owner�s representative in attendance, the thickness measurement company operator (as applicable) and the master of the ship for the purpose to ascertain that all the arrangements envisaged in the survey programme are in place, so as to ensure the safe and efficient conduct of the survey work to be carried out.

SURVEY REPORTING PRINCIPLES

As a principle, for bulk carriers subject to the Guidelines, the surveyor should include the following contents in his report for survey of hull structure and piping systems, as relevant for the survey.


Page 23


1 General 1.1 A survey report should be generated in the following cases:

.1 in connection with commencement, continuation and/or completion of

periodical hull surveys, i.e. annual, intermediate and renewal surveys, as relevant;

.2 when structural damages/defects have been found; .3 when repairs, renewals or modifications have been carried out; and .4 when condition of class (recommendation) has been imposed or has been

deleted. 1.2 The reporting should provide:

.1 evidence that prescribed surveys have been carried out in accordance with applicable requirements;

.2 documentation of surveys carried out with findings, repairs carried out and

condition of class (recommendation) imposed or deleted;

.3 survey records, including actions taken, which should form an auditable documentary trail. Survey reports should be kept in the survey report file required to be on board;

.4 information for planning of future surveys; and

.5 information which may be used as input for maintenance of classification

rules and instructions. 1.3 When a survey is split between different survey stations, a report should be made for each portion of the survey. A list of items surveyed, relevant findings and an indication of whether the item has been credited, are to be made available to the next attending surveyor, prior to continuing or completing the survey. Thickness measurement and tank testing carried out is also to be listed for the next surveyor.

2 Extent of the survey 2.1 Identification of compartments where an overall survey has been carried out. 2.2 Identification of locations, in each ballast tank and cargo hold including hatch covers and coamings, where a close-up survey has been carried out, together with information on the means of access used. 2.3 Identification of locations, in each ballast tank and cargo hold including hatch covers and coamings, where thickness measurement has been carried out.



Note: As a minimum, the identification of location of close-up survey and thickness measurement should include a confirmation with description of individual structural members corresponding to the extent of requirements stipulated in Annex A based on type of periodical survey and the ship's age.

Where only partial survey is required, i.e. 25% of shell frames, one transverse web, two selected cargo hold transverse bulkheads, the identification should include location within each ballast tank and cargo hold by reference to frame numbers.

2.4 For areas in ballast tanks and cargo holds where protective coating is found to be in good condition and the extent of close-up survey and/or thickness measurement has been specially considered, structures subject to special consideration should be identified. 2.5 Identification of tanks subject to tank testing. 2.6 Identification of piping systems on deck and within cargo holds, ballast tanks, pipe tunnels, cofferdams and void spaces where:

.1 examination including internal examination of piping with valves and fittings and thickness measurement, as relevant, has been carried out; and

.2 operational test to working pressure has been carried out.

3 Result of the survey

3.1 Type, extent and condition of protective coating in each tank, as relevant (rated GOOD, FAIR or POOR) including identification of tanks fitted with anodes. 3.2 Structural condition of each compartment with information on the following, as relevant:

.1 identification of findings, such as:

.1.1 corrosion with description of location, type and extent; .1.2 areas with substantial corrosion; .1.3 cracks/fractures with description of location and extent; .1.4 buckling with description of location and extent; and .1.5 indents with description of location and extent;

.2 identification of compartments where no structural damages/defects are

found. The report may be supplemented by sketches/photos; and .3 thickness measurement report should be verified and signed by the

surveyor controlling the measurements on board.


Page 25


4 Actions taken with respect to findings 4.1 Whenever the attending surveyor is of the opinion that repairs are required, each item to be repaired should be identified in a numbered list. Whenever repairs are carried out, details of the repairs effected should be reported by making specific reference to relevant items in the numbered list. 4.2 Repairs carried out should be reported with identification of:

.1 compartment; .2 structural member; .3 repair method (i.e. renewal or modification), including:

.3.1 steel grades and scantlings (if different from the original); .3.2 sketches/photos, as appropriate;

.4 repair extent; and .5 non-destructive test (NDT)/tests.

4.3 For repairs not completed at the time of survey, condition of class/recommendation should be imposed with a specific time limit for the repairs. In order to provide correct and proper information to the surveyor attending for survey of the repairs, condition of class/recommendation should be sufficiently detailed with identification of each item to be repaired. For identification of extensive repairs, reference may be made to the survey report.�

39 Table 1 and table 2 in appendix 3 of Annex 8 are deleted and table 3 is renumbered as table 1. 40 In paragraph 1 of annex 9, the words �the paragraph 5.1.6 of annex A� are replaced with �5.1.5�. 41 The following new Annex 13 is added:

�ANNEX 13

Strength of cargo hatch cover securing arrangements for bulk carriers

1 Securing devices

The strength of securing devices should comply with the following requirements:

.1 Panel hatch covers should be secured by appropriate devices (bolts, wedges or similar) suitably spaced alongside the coamings and between cover elements. Arrangement and spacing should be determined with due



attention to the effectiveness for weather-tightness, depending upon the type and the size of the hatch cover, as well as on the stiffness of the cover edges between the securing devices.

.2 The net sectional area of each securing device is not to be less than:

A = 1.4 a / f (cm2)

where:

a = spacing between securing devices not to be taken less than

2 metres f = (σY / 235)e σY = specified minimum upper yield stress in N/mm2 of the steel

used for fabrication, not to be taken greater than 70% of the ultimate tensile strength

e = 0.75 for σY > 235 = 1.0 for σY ≤ 235

Rods or bolts should have a net diameter not less than 19 mm for hatchways exceeding 5 m2 in area.

.3 Between cover and coaming and at cross-joints, a packing line pressure

sufficient to obtain weathertightness should be maintained by the securing devices. For packing line pressures exceeding 5 N/mm, the cross section area should be increased in direct proportion. The packing line pressure should be specified.

.4 The cover edge stiffness should be sufficient to maintain adequate sealing

pressure between securing devices. The moment of inertia, I, of edge elements be less than:

I = 6 p a4 (cm4)

where:

p = packing line pressure in N/mm, minimum 5 N/mm a = spacing in m of securing devices

5 Securing devices should be of reliable construction and securely attached

to the hatchway coamings, decks or covers. Individual securing devices on each cover are to have approximately the same stiffness characteristics.

.6 Where rod cleats are fitted, resilient washers or cushions should be

incorporated.

.7 Where hydraulic cleating is adopted, a positive means should be provided to ensure that it remains mechanically locked in the closed position in the event of failure of the hydraulic system.


Page 27


2 Stoppers

2.1 No. 1 and 2 hatch covers should be effectively secured, by means of stoppers, against the transverse forces arising from a pressure of 175 kN/m2.

2.2 No. 2 hatch covers should be effectively secured, by means of stoppers, against the longitudinal forces acting on the forward end arising from a pressure of 175 kN/m2.

2.3 No. 1 hatch cover should be effectively secured, by means of stoppers, against the longitudinal forces acting on the forward end arising from a pressure of 230 kN/m2. This pressure may be reduced to 175 kN/m2 if a forecastle is fitted.

2.4 The equivalent stress in stoppers and their supporting structures and calculated in the throat of the stopper welds is not to exceed the allowable value of 0.8 σY.

3 Materials and welding Where stoppers or securing devices are fitted to comply with this annex, they should be manufactured of materials, including welding electrodes, to the satisfaction of the Administration.�

DURING SURVEYS OF OIL TANKERS OTHER THAN DOUBLE HULL OIL TANKERS�

43 The text of the new Part A is as follows:

�Part A

GUIDELINES ON THE ENHANCED PROGRAMME OF INSPECTIONS DURING SURVEYS OF DOUBLE HULL OIL TANKERS



1 General 1.1 Application 1.1.1 The Guidelines should apply to all self-propelled double hull oil tankers of 500 gross tonnage and above. 1.1.2 The Guidelines should apply to surveys of hull structure and piping systems in way of cargo tanks, pump rooms, cofferdams, pipe tunnels, void spaces within the cargo area and all ballast tanks. The surveys should be carried out during the surveys prescribed by regulation I/10 of the 1974 SOLAS Convention, as amended. 1.1.3 The Guidelines contain the extent of examination, thickness measurements and tank testing. The survey should be extended when substantial corrosion and/or structural defects are found and include additional close-up survey when necessary. 1.2 Definitions 1.2.1 Double hull oil tanker is a ship which is constructed primarily for the carriage of oil in bulk, which have the cargo tanks protected by a double hull which extends for the entire length of the cargo area, consisting of double sides and double bottom spaces for the carriage of water ballast or void spaces. 1.2.2 A ballast tank is a tank which is used solely for water ballast. 1.2.3 Overall survey is a survey intended to report on the overall condition of the hull structure and determine the extent of additional close-up surveys. 1.2.4 Close-up survey is a survey where the details of structural components are within the close visual inspection range of the surveyor, i.e. preferably within reach of hand. 1.2.5 Transverse section includes all longitudinal members such as plating, longitudinals and girders at the deck, sides, bottom, inner bottom and longitudinal bulkheads. 1.2.6 Representative tanks are those which are expected to reflect the condition of other tanks of similar type and service and with similar corrosion protection systems. When selecting representative tanks account should be taken of the service and repair history onboard and identifiable critical and/or suspect areas. 1.2.7 Suspect areas are locations showing Substantial Corrosion and/or are considered by the surveyor to be prone to rapid wastage. 1.2.8 Substantial corrosion is an extent of corrosion such that assessment of corrosion pattern indicates a wastage in excess of 75% of allowable margins, but within acceptable limits.


Page 29


1.2.9 Corrosion prevention system is normally considered either:

.1 a full hard coating, or .2 a full hard coating supplemented by anodes.

Protective coating should usually be epoxy coating or equivalent. Other coating systems may be considered acceptable as alternatives provided that they are applied and maintained in compliance with the manufacturer�s specification. Where soft coatings have been applied, safe access should be provided for the surveyor to verify the effectiveness of the coating and to carry out an assessment of the condition of internal structures which may include spot removal of the coating. When safe access cannot be provided, the soft coating should be removed. 1.2.10 Coating condition is defined as follows:

GOOD condition with only minor spot rusting,

FAIR condition with local breakdown of coating at edges of stiffeners and weld connections and/or light rusting over 20% or more of areas under consideration, but less than as defined for POOR condition,

POOR condition with general breakdown of coating over 20% or more of

areas or hard scale at 10% or more of areas under consideration. 1.2.11 Critical structural areas are locations which have been identified from calculations to require monitoring or from the service history of the subject ship or from similar or sister ships to be sensitive to cracking, buckling or corrosion which would impair the structural integrity of the ship. 1.2.12 Cargo area is an area as defined in regulation II-2/3.6 of the 1974 SOLAS Convention, as amended. 1.2.13 Intermediate survey is a survey carried out either at the second or the third annual survey or between these surveys. 1.2.14 A prompt and thorough repair is a permanent repair completed at the time of survey to the satisfaction of the Surveyor, therein removing the need for the imposition of any associated condition of classification or recommendation. 1.2.15 Specially considered means sufficient close-up inspection and thickness measurements are taken to confirm the actual average condition of the structure under coating. 1.3 Repairs 1.3.1 Any damage in association with wastage over the allowable limits (including buckling, grooving, detachment or fracture), or extensive areas of wastage over the allowable limits, which affects or, in the opinion of the Administration, will affect the



ship�s structural, watertight or weathertight integrity, should be promptly and thoroughly (see 1.2.14) repaired. Areas to be considered include:

.1 bottom structure and bottom plating;

.2 side structure and side plating;

.3 deck structure and deck plating;

.4 inner bottom structure and inner bottom plating;

.5 inner side structure and inner side plating;

.6 longitudinal bulkhead(s) structure and longitudinal bulkhead(s) plating, where fitted;

.7 transverse watertight or oiltight bulkheads structure and transverse

watertight or oiltight bulkheads plating;

.8 hatch covers or hatch coamings, where fitted; and

.9 items in paragraph 3.3. Where adequate repair facilities are not available, the Administration may allow the ship to proceed directly to a repair facility. This may require discharging the cargo and/or temporary repairs for the intended voyage. 1.3.2 Additionally, when a survey results in the identification of corrosion or structural defects, either of which, in the opinion of the Administration, will impair the ship�s fitness for continued service, remedial measures should be implemented before the ship continues in service. 1.4 Surveyors For tankers of 20,000 tons deadweight and above, two surveyors should jointly carry out the first scheduled renewal survey after the tanker passes 10 years of age, and all subsequent renewal surveys and intermediate surveys. If the surveys are carried out by a recognized organization, the surveyors should be exclusively employed by such recognized organizations. 2 Renewal survey 2.1 General 2.1.1 The renewal survey may be commenced at the fourth annual survey and be progressed during the succeeding year with a view to completion by the fifth anniversary date. 2.1.2 As part of the preparation for the renewal survey the survey programme should be dealt with in advance of the renewal survey. The thickness measurement should not be carried out before the fourth annual survey.


Page 31


2.1.3 The survey should include, in addition to the requirements of the annual survey, examination, tests and checks of sufficient extent to ensure that the hull and related piping as required in 2.1.5 is in a satisfactory condition and is fit for its intended purpose for the new period of validity of the Cargo Ship Safety Construction Certificate, subject to proper maintenance and operation and to periodical surveys being carried out. 2.1.4 All cargo tanks, ballast tanks, pump-rooms, pipe tunnels, cofferdams and void spaces bounding cargo tanks, decks and outer hull should be examined, and this examination should be supplemented by thickness measurement and testing as deemed necessary, to ensure that the structural integrity remains effective. The examination should be sufficient to discover substantial corrosion, significant deformation, fractures, damages or other structural deterioration. 2.1.5 Cargo piping on deck, including crude oil washing (COW) piping, and cargo and ballast piping within the above tanks and spaces should be examined and operationally tested to working pressure to attending surveyor�s satisfaction to ensure that tightness and condition remain satisfactory. Special attention should be given to any ballast piping in cargo tanks and cargo piping in ballast tanks and void spaces, and surveyors should be advised on all occasions when this piping, including valves and fittings, are open during repair periods and can be examined internally. 2.2 Dry-dock survey [2.2.1 A survey in dry-dock should be a part of the renewal survey. There should be a minimum of two inspections of the outside of the ship's bottom during the five-year period of the Safety Construction Certificate. In all cases, the maximum interval between bottom inspections should not exceed 36 months.] 2.2.2 For ships of 15 years of age and over, inspection of the outside of the ship�s bottom should be carried out with the ship in dry dock. For ships of less than 15 years of age, alternate inspections of the ship�s bottom not conducted in conjunction with the renewal survey may be carried out with the ship afloat. Inspection of the ship afloat should only be carried out when the conditions are satisfactory and the proper equipment and suitably qualified staff is available. 2.2.3 If a survey in dry-dock is not completed in conjunction with the renewal survey or if the 36 month maximum interval referred to in 2.2.1 is not complied with, the Cargo Ship Safety Construction Certificate should cease to be valid until a survey in dry-dock is completed. 2.3 Tank corrosion prevention system Where provided, the condition of the corrosion prevention system of cargo tanks should be examined. A ballast tank where a protective coating is found in POOR condition and it is not renewed, or where soft coating has been applied, or where a protective coating has not been applied from the time of construction, the tank in question should be examined at annual intervals. Thickness measurement should be carried out as deemed necessary by the surveyor.



2.4 Extent of overall and close-up surveys 2.4.1 An overall survey of all integral tanks and spaces should be carried out at the renewal survey. 2.4.2 The requirements for close-up surveys at the renewal survey are given in annex 1. 2.4.3 The surveyor may extend the scope of the close-up survey as deemed necessary taking into account the maintenance of the tanks under survey, the condition of the corrosion prevention system and also in the following cases:

.1 in particular, tanks having structural arrangements or details which have suffered defects in similar tanks or on similar ships according to available information;

.2 in tanks which have structures with reduced scantlings in association with

a corrosion prevention system approved by the Administration. 2.4.4 For areas in tanks where coatings are found to be in GOOD condition as defined in 1.2.10, the extent of close-up surveys according to annex 1 may be specially considered by the Administration. 2.5 Extent of thickness measurements 2.5.1 The requirements for thickness measurements at the renewal survey are given in annex 2. 2.5.2 Where substantial corrosion as defined in 1.2.8 is found, the extent of thickness measurements should be increased in accordance with the requirements of annex 4. 2.5.3 The surveyor may extend the thickness measurements as deemed necessary. 2.5.4 For areas in tanks where coatings are found to be in GOOD condition as defined in 1.2.10, the extent of thickness measurements according to annex 2 may be specially considered by the Administration. 2.5.5 Transverse sections should be chosen where the largest reductions are suspected to occur or are revealed from deck plating measurements. 2.5.6 In cases where two or three sections are to be measured, at least one should include a ballast tank within 0.5L amidships. 2.6 Extent of tank pressure testing 2.6.1 The requirements for tank pressure testing at the renewal survey are given in annex 3. 2.6.2 The surveyor may extend the tank pressure testing as deemed necessary. 2.6.3 Generally, the pressure should correspond to a water level to the top of access hatches for cargo tanks, or top of air pipes for ballast tanks.

3 Annual survey 3.1 General The annual survey should consist of an examination for the purpose of ensuring, as far as practicable, that the hull and piping are maintained in a satisfactory condition and should take into account the service history, condition and extent of the corrosion prevention system of ballast tanks and areas identified in the survey report file. 3.2 Examination of the hull 3.2.1 Examination of the hull plating and its closing appliances should be carried out as far as can be seen. 3.2.2 Examination of watertight penetrations should be carried out as far as practicable. 3.3 Examination of weather decks 3.3.1 Examination of cargo tank openings including gaskets, covers, coamings and flame screens. 3.3.2 Examination of cargo tank pressure/vacuum valves and flame screens. 3.3.3 Examination of flame screens on vents to all bunker and oily slop tanks. 3.3.4 Examination of cargo, crude oil washing, bunker and vent piping systems, including vent masts and headers. 3.4 Examination of cargo pump-rooms and pipe tunnels 3.4.1 Examination of all bulkheads for signs of oil leakage or fractures and, in particular, the sealing arrangements of all penetrations of bulkheads. 3.4.2 Examination of the condition of all piping systems and pipe tunnels. 3.5 Examination of ballast tanks 3.5.1 Examination of ballast tanks should be carried out when required as a consequence of the results of the renewal survey and intermediate survey. When extensive corrosion is found, thickness measurements should be carried out. 3.5.2 Where substantial corrosion as defined in 1.2.8 is found, the extent of thickness measurements should be increased in accordance with the requirements in annex 4. 3.5.3 Double hull oil tankers exceeding 15 years of age All ballast tanks adjacent to (i.e. with a common plane boundary) a cargo or fuel tank with any means of heating should be examined internally. When considered necessary by the surveyor, thickness measurement should be carried out and if the results of these



thickness measurements indicate that substantial corrosion is found, the extent of thickness measurements should be increased in accordance with annex 4. Ballast tanks which were found, at the previous intermediate or renewal survey, to have no substantial corrosion within the tank and which were found in compliance with either of the following conditions:

.1 coating in GOOD condition; or

.2 coating of the common boundary, including adjacent structures, in GOOD condition and the coating of the remaining parts of the tank in FAIR condition,

may be specially considered by the Administration. 4 Intermediate survey 4.1 General 4.1.1 Items that are additional to the requirements of the annual survey may be surveyed either at the second or third annual survey or between these surveys. 4.1.2 The survey extent of cargo and ballast tanks dependent on the age of the ship is specified in 4.2, 4.3 and 4.4. and shown in annex 5. 4.1.3 For weather decks, an examination as far as applicable of cargo, crude oil washing, bunker, ballast, steam and vent piping systems as well as vent masts and headers. If upon examination there is any doubt as to the condition of the piping, the piping may be required to be pressure tested, thickness measured or both. 4.2 Oil tankers of 5 to 10 years of age 4.2.1 The requirements of 4.1.3 apply. 4.2.2 For tanks used for salt-water ballast, an overall survey of representative tanks selected by the surveyor should be carried out. If the overall survey of salt-water ballast tanks reveals no visible structural defects, the examination may be limited to verification that the protective coatings remain efficient. 4.2.3 Where POOR coating condition, corrosion or other defects are found in salt water ballast tanks or where a protective coating was not applied from the time of construction, the examination should be extended to other ballast tanks of the same type. 4.2.4 In salt water ballast tanks where a protective coating is found in POOR condition and it is not renewed, where soft coating has been applied, or where a protective coating was not applied from the time of construction, the tanks in question should be examined and thickness measurements carried out as considered necessary at annual intervals. 4.3 Oil tankers of 10 to 15 years of age 4.3.1 The requirements of 4.2 apply.


Page 35


4.3.2 An overall survey of at least two representative cargo tanks should be carried out. 4.3.3 For ballast tanks, where fitted, an overall survey of all such tanks should be carried out. If such survey reveals no visible structural defects, the survey may be limited to a verification that the protective coatings remain efficient. 4.3.4 Extent of close-up survey Ballast tanks: to the same extent as previous renewal survey; Cargo tanks: the extent of survey should be based on the record of the previous renewal

survey and repair history of the tanks, and be applied to two cargo tanks after the second renewal survey.

The minimum requirements of close-up surveys are given in annex 5. The extent of close-up surveys may be extended as stated in 2.4.3. For areas in tanks where coatings are found to be in GOOD condition, the extent of the close-up surveys according to annex 5 may be specially considered by the Administration. 4.3.5 Extent of thickness measurements The extent of thickness measurements is also given in annex 5. The minimum requirements for thickness measurements at the intermediate survey are areas found to be suspect areas according to 1.2.7 at the previous renewal survey. Where substantial corrosion as defined in 1.2.8 is found, the extent of the thickness measurements according to annex 5 should be increased in accordance with the requirements of annex 4. 4.4 Oil tankers exceeding 15 years of age The requirements of the intermediate survey should be to the same extent as the previous renewal survey as required in 2 and 5.1. However, pressure testing of cargo and ballast tanks is not required unless deemed necessary by the attending surveyor. 5 Preparations for survey 5.1 Survey programme 5.1.1 A specific survey programme should be worked out in advance of the renewal survey by the owner in co-operation with the Administration. The survey programme should be in a written format based on the information in annex 6A. The survey should not commence until the survey programme has been agreed. 5.1.1.1 Prior to the development of the survey programme, the survey planning questionnaire should be completed by the owner based on the information set out in annex 6B, and forwarded to the Administration. 5.1.2 In developing the survey programme, the following documentation should be collected and consulted with a view to selecting tanks, areas, and structural elements to be examined:



.1 survey status and basic ship information;

.2 documentation on board, as described in 6.2 and 6.3;

.3 main structural plans of cargo and ballast tanks (scantlings drawings), including information regarding use of high-tensile steels (HTS);

.4 Condition Evaluation Report, according to annex 9;

.12 damage experience related to the ship in question; and

.13 critical structural areas and suspect areas, where relevant. 5.1.4 The Administration will advise the owner of the maximum acceptable structural corrosion diminution levels applicable to the ship. 5.1.5 Use may also be made of the Guidelines for technical assessment in conjunction with the planning of enhanced surveys for tankers, contained in annex 11. These Guidelines are a recommended tool which may be invoked at the discretion of the Administration, when considered necessary and appropriate, in conjunction with the preparation of the required survey programme. 5.2 Conditions for survey 5.2.1 The owner should provide the necessary facilities for a safe execution of the survey. 5.2.1.1 In order to enable the attending surveyors to carry out the survey, provisions for proper and safe access should be agreed between the owner and the Administration. 5.2.1.2 Details of the means of access should be provided in the survey planning questionnaire. 5.2.1.3 In cases where the provisions of safety and required access are judged by the attending surveyors not to be adequate, the survey of the spaces involved should not proceed. 5.2.2 Tanks and spaces should be safe for access. Tanks and spaces should be gas free and properly ventilated. Prior to entering a tank, void or enclosed space, it should be verified that the atmosphere in that space is free from hazardous gas and contains sufficient oxygen.



5.2.3 Tanks and spaces should be sufficiently clean and free from water, scale, dirt, oil residues, sediments etc., to reveal corrosion, deformation, fractures, damages or other structural deterioration as well as the condition of the coating. In particular this applies to areas which are subject to thickness measurement. 5.2.4 Sufficient illumination should be provided to reveal corrosion, deformation, fractures, damages or other structural deterioration as well as the condition of the coating. 5.2.5 The surveyor(s) should always be accompanied by at least one responsible person, assigned by the owner, experienced in tank and enclosed spaces inspection. In addition a backup team of at least two experienced persons should be stationed at the hatch opening of the tank or space that is being surveyed. The back-up team should continuously observe the work in the tank or space and should keep lifesaving and evacuation equipment ready for use. 5.2.6 A communication system should be arranged between the survey party in the tank or space being examined, the responsible officer on deck and, as the case may be, the navigation bridge. The communication arrangements should be maintained throughout the survey. 5.3 Access to structures∗ 5.3.1 For overall surveys, means should be provided to enable the surveyor to examine the structure in a safe and practical way. 5.3.2 For close-up surveys, one or more of the following means for access, acceptable to the surveyor, should be provided:

.1 permanent staging and passages through structures;

.2 temporary staging and passages through structures;

.3 lifts and moveable platforms;

.4 boats or rafts;

.5 portable ladders; .6 other equivalent means. 5.4 Equipment for survey 5.4.1 Thickness measurement should normally be carried out by means of ultrasonic test equipment. The accuracy of the equipment should be proven to the surveyor as required. 5.4.2 One or more of the following fracture detection procedures may be required if deemed necessary by the surveyor:

∗ Refer to MSC/Circ.686, Guidelines on the means of access to structures for inspection and

maintenance of oil tankers and bulk carriers.


Page 39


.1 radiographic equipment;

.2 ultrasonic equipment;

.3 magnetic particle equipment;

.4 dye penetrant;

.5 other equivalent means.

5.4.3 Explosimeter, oxygen-meter, breathing apparatus, lifelines, riding belts with rope and hook and whistles together with instructions and guidance on their use should be made available during the survey. A safety check-list should be provided. 5.4.4 Adequate and safe lighting should be provided for the safe and efficient conduct of the survey. 5.4.5 Adequate protective clothing should be made available and used during the survey (e.g. safety helmet, gloves, safety shoes, etc). 5.5 Surveys at sea or at anchorage 5.5.1 Surveys at sea or at anchorage may be accepted provided the surveyor(s) is given the necessary assistance from the personnel on board. Necessary precautions and procedures for carrying out the survey should be in accordance with 5.1, 5.2, 5.3 and 5.4. 5.5.2 A communication system should be arranged between the survey party in the tank and the responsible officer on deck. This system should also include the personnel in charge of ballast pump handling if boats or rafts are used. 5.5.3 Surveys of tanks by means of boats or rafts may only be undertaken with the agreement of the surveyor, who should take into account the safety arrangements provided, including weather forecasting and ship response in reasonable sea conditions. 5.5.4 When rafts or boats are used for close-up surveys, the following conditions should be observed:

.1 only rough duty, inflatable rafts or boats, having satisfactory residual buoyancy and stability even if one chamber is ruptured, should be used;

.2 the boat or raft should be tethered to the access ladder and an additional


.3 appropriate lifejackets should be available for all participants;

.4 the surface of water in the tank should be calm (under all foreseeable

conditions the expected rise of water within the tank should not exceed 0.25 m) and the water level either stationary or falling. On no account should the level of the water be rising while the boat or raft is in use;



.5 the tank or space must contain clean ballast water only. Even a thin sheen

of oil on the water is not acceptable;

.6 at no time should the water level be allowed to be within 1 m of the deepest under deck web face flat so that the survey team is not isolated from a direct escape route to the tank hatch. Filling to levels above the deck transverses should only be contemplated if a deck access manhole is fitted and open in the bay being examined, so that an escape route for the survey party is available at all times. Other effective means of escape to the deck may be considered;

.7 if the tanks (or spaces) are connected by a common venting system, or

inert gas system, the tank in which the boat or raft should be used should be isolated to prevent a transfer of gas from other tanks (or spaces).

5.5.5 Rafts or boats alone may be allowed for inspection of the under deck areas of tanks or spaces if the depth of the webs is 1.5 m or less. 5.5.6 If the depth of the webs is more than 1.5 m, rafts or boats alone may be allowed only:

.1 when the coating of the under deck structure is in GOOD condition and there is no evidence of wastage; or

.2 if a permanent means of access is provided in each bay to allow safe entry

and exit. This means of access should be direct from the deck via a vertical ladder with a small platform fitted approximately 2 m below the deck. Other effective means of escape to the deck may be considered.

If neither of the above conditions are met, then staging or other equivalent means should be provided for the survey of the under deck areas. 5.5.7 The use of rafts or boats alone in paragraphs 5.5.5 and 5.5.6 does not preclude the use of boats or rafts to move about within a tank during a survey. 5.6 Survey planning meeting 5.6.1 Proper preparation and close co-operation between the attending surveyor(s) and the owner�s representatives onboard prior to and during the survey are an essential part in the safe and efficient conduct of the survey. During the survey on board safety meetings should be held regularly. 5.6.2 Prior to commencement of any part of the renewal and intermediate survey, a survey planning meeting should be held between the attending surveyor(s), the owner�s representative in attendance, the thickness measurement company operator (as applicable) and the master of the ship for the purpose of ascertaining that all the arrangements envisaged in the survey programme are in place, so as to ensure the safe and efficient conduct of the survey work to be carried out.

6.3 Supporting documents The following additional documentation should be available on board:

.1 all documents required by 5.1.2;

.2 survey programme as required by 5.1 until such time as the renewal survey has been completed; and

.3 any other information that would help to identify critical structural areas

and/or suspect areas requiring inspection. 6.4 Review of documentation on board Prior to survey, the surveyor should examine the completeness of the documentation on board and its contents as a basis for the survey. 7 Procedures for thickness measurements 7.1 General 7.1.1 The required thickness measurements, if not carried out by the recognized organization acting on behalf of the Administration, should be witnessed by a surveyor of the recognized organization. The surveyor should be on board to the extent necessary to control the process. 7.1.2 The thickness measurement company should be part of the survey planning meeting to be held prior to commencing the survey. 7.1.3 In all cases the extent of the thickness measurements should be sufficient as to represent the actual average condition. 7.2 Certification of thickness measurement company The thickness measurements should be carried out by a qualified company certified by an organization recognized by the Administration according to principles stated in annex 7. 7.3 Reporting 7.3.1 A thickness measurement report should be prepared and submitted to the Administration. The report should give the location of measurements, the thickness measured as well as corresponding original thickness. Furthermore, the report should give the date when the measurements were carried out, type of measuring equipment, names of personnel and their qualifications and be signed by the operator. The thickness measurement report should follow the principles as specified in the recommended procedures for thickness measurements set out in annex 10. 7.3.2 The surveyor should verify and countersign the thickness measurement reports.

8 Reporting and evaluation of survey 8.1 Evaluation of survey report 8.1.1 The data and information on the structural condition of the ship collected during the survey should be evaluated for acceptability and continued structural integrity of the ship. 8.1.2 In case of oil tankers of 130 m in length and upwards (as defined in the International Convention on Load Lines in force), the ship�s longitudinal strength should be evaluated by using the thickness of structural members measured, renewed and reinforced, as appropriate, during the renewal survey of safety construction carried out after the ship reached 10 years of age, in accordance with the criteria for longitudinal strength of the ship�s hull girder for oil tankers specified in annex 12. 8.1.3 The analysis of data should be carried out and endorsed by the Administration and the conclusions of the analysis should form a part of the condition evaluation report. 8.1.4 The final result of the evaluation of the ship�s longitudinal strength required in 8.1.2, after renewal or reinforcement work of structural members, if carried out as a result of initial evaluation, should be reported as a part of the condition evaluation report. 8.2 Reporting 8.2.1 Principles for survey reporting are shown in annex 8. 8.2.2 When a survey is split between different survey stations, a report should be made for each portion of the survey. A list of items examined and/or tested (pressure testing, thickness measurements etc.) and an indication of whether the item has been credited, should be made available to the next attending surveyor(s), prior to continuing or completing the survey. 8.2.3 A condition evaluation report of the survey and results should be issued to the owner as shown in annex 9 and placed on board the ship for reference at future surveys. The condition evaluation report should be endorsed by the Administration.

Page 67


ANNEX 8

SURVEY REPORTING PRINCIPLES

As a principle, for oil tankers subject to ESP, the surveyor should include the following contents in his report for survey of hull structure and piping systems, as relevant for the survey. 1 General 1.1 A survey report should be generated in the following cases:

.1 in connection with commencement, continuation and/or completion of periodical hull surveys, i.e. annual, intermediate and renewal surveys, as relevant;

.2 when structural damages/defects have been found;

.3 when repairs, renewals or modifications have been carried out; and

.4 when condition of class (recommendation) has been imposed or deleted.

1.2 The reporting should provide:

.1 evidence that prescribed surveys have been carried out in accordance with applicable requirements;

.2 documentation of surveys carried out with findings, repairs carried out and

condition of class (recommendation) imposed or deleted;

.3 survey records, including actions taken, which should form an auditable documentary trail. Survey reports should be kept in the survey report file required to be on board;

.4 information for planning of future surveys; and

.5 information which may be used as input for maintenance of classification

rules and instructions. 1.3 When a survey is split between different survey stations, a report should be made for each portion of the survey. A list of items surveyed, relevant findings and an indication of whether the item has been credited, should be made available to the next attending surveyor, prior to continuing or completing the survey. Thickness measurement and tank testing carried out should also be listed for the next surveyor. 2 Extent of the survey 2.1 Identification of compartments where an overall survey has been carried out.



2.2 Identification of locations, in each tank, where a close-up survey has been carried out, together with information of the means of access used. 2.3 Identification of locations, in each tank, where thickness measurement has been carried out. Note: As a minimum, the identification of location of close-up survey and thickness

measurement should include a confirmation with description of individual structural members corresponding to the extent of requirements stipulated in this part of Annex B based on type of periodical survey and the ship's age.

Where only partial survey is required, i.e. one web frame ring/one deck transverse, the identification should include location within each ballast tank and cargo hold by reference to frame numbers.

2.4 For areas in tanks where protective coating is found to be in good condition and the extent of close-up survey and/or thickness measurement has been specially considered, structures subject to special consideration should be identified. 2.5 Identification of tanks subject to tank testing. 2.6 Identification of piping systems on deck, including crude oil washing (COW) piping, and ballast piping within cargo and ballast tanks, pipe tunnels, cofferdams and void spaces where:

.1 examination including internal examination of piping with valves and fittings and thickness measurement, as relevant, has been carried out; and

.2 operational test to working pressure has been carried out.

3 Result of survey 3.1 Type, extent and condition of protective coating in each tank, as relevant (rated GOOD, FAIR or POOR), including identification of tanks fitted with anodes. 3.2 Structural condition of each compartment with information on the following, as

relevant:

.1 Identification of findings, such as:

.1.1 corrosion with description of location, type and extent;

.1.2 areas with substantial corrosion;

.1.3 cracks/fractures with description of location and extent;

.1.4 buckling with description of location and extent; and

.1.5 indents with description of location and extent.


Page 69


.2 Identification of compartments where no structural damages/defects are found. The report may be supplemented by sketches/photos.

.3 Thickness measurement report should be verified and signed by the

surveyor controlling the measurements on board.

.4 Evaluation result of longitudinal strength of the hull girder of oil tankers of 130 m in length and upwards and over 10 years of age. The following data should be included, as relevant:

.4.1 measured and as-built transverse sectional areas of deck and

bottom flanges;

.4.2 diminution of transverse sectional areas of deck and bottom flanges; and

.4.3 details of renewals or reinforcements carried out, as relevant

(see 4.2). 4 Actions taken with respect to findings 4.1 Whenever the attending surveyor is of the opinion that repairs are required, each item to be repaired should be identified in a numbered list. Whenever repairs are carried out, details of the repairs effected should be reported by making specific reference to relevant items in the numbered list. 4.2 Repairs carried out should be reported with identification of:

.1 compartment;

.2 structural member;

.3 repair method (i.e. renewal or modification), including:

.3.1 steel grades and scantlings (if different from the original);

.3.2 sketches/photos, as appropriate;

.4 repair extent; and

.5 non-destructive tests (NDT). 4.3 For repairs not completed at the time of survey, condition of class/recommendation should be imposed with a specific time limit for the repairs. In order to provide correct and proper information to the surveyor attending for survey of the repairs, condition of class/recommendation should be sufficiently detailed with identification of each item to be repaired. For identification of extensive repairs, reference may be given to the survey report.

ANNEX 11

GUIDELINES FOR TECHNICAL ASSESSMENT IN CONJUNCTION WITH

THE PLANNING OF ENHANCED SURVEYS FOR OIL TANKERS

Renewal survey 1 Introduction These Guidelines contain information and suggestions concerning technical assessments which may be of use in conjunction with the planning of renewal surveys of oil tankers. As indicated in 5.1.5, these Guidelines are a recommended tool which may be invoked at the discretion of an Administration, when considered necessary and appropriate, in conjunction with the preparation of the required survey programme. 2 Purpose and principles 2.1 Purpose The technical assessments described in these Guidelines should assist in identifying critical structural areas, nominating suspect areas and in focusing attention on structural elements or areas of structural elements which may be particularly susceptible to, or evidence a history of, wastage or damage. This information may be useful in nominating locations, areas and tanks for thickness measurement, close-up survey and tank testing. 2.2 Minimum requirements These Guidelines may not be used to reduce the requirements of annexes 1, 2 and 3 for close-up survey, thickness measurement and tank testing, respectively, which are, in all cases, to be complied with as a minimum. 2.3 Timing As with other aspects of survey planning, the technical assessments described in these Guidelines should be completed out by the owner or operator in co-operation with the Administration well in advance of the commencement of the renewal survey, i.e., prior to commencing the survey and normally at least 12 to 15 months before the survey's completion due date. 2.4 Aspects to be considered Technical assessments, which may include quantitative or qualitative evaluation of relative risks of possible deterioration, of the following aspects of a particular ship may be used as a basis for the nomination of tanks and areas for survey of:

.1 design features such as stress levels on various structural elements, design details and extent of use of high-tensile steel (HTS);


Page 97


.2 former history with respect to corrosion, cracking, buckling, indents and repairs for the particular ship as well as similar vessels, where available; and

.3 information with respect to types of cargo carried, use of different tanks

for cargo/ballast, protection of tanks and condition of coating, if any. Technical assessments of the relative risks of susceptibility to damage or deterioration of various structural elements and areas should be judged and decided on the basis of recognized principles and practices, such as may be found in references 1 and 2. 3 Technical assessment 3.1 General 3.1.1 There are three basic types of possible failure which may be the subject of a technical assessment in connection with the planning of surveys: corrosion, cracks and buckling. Contact damages are not normally covered by the survey plan since indents are usually noted in memoranda and assumed to be dealt with as a normal routine by surveyors. 3.1.2 Technical assessments performed in conjunction with the survey planning process should, in principle, be as shown schematically in figure 1 which depicts how technical assessments can be carried out in conjunction with the survey planning process. The approach is basically an evaluation of the risk, based on the knowledge and experience related to design and corrosion. 3.1.3 The design should be considered with respect to structural details which may be susceptible to buckling or cracking as a result of vibration, high stress levels or fatigue. 3.1.4 Corrosion is related to the ageing process and is closely connected with the quality of corrosion protection at newbuilding and subsequent maintenance during the service life. Corrosion may also lead to cracking and/or buckling. 3.2 Methods 3.2.1 Design details 3.2.1.1 Damage experience related to the ship in question and similar ships, where available, are the main source of information to be used in the process of planning. In addition, a selection of structural details from the design drawings should be included. Typical damage experience to be considered will consist of: .1.1 number, extent, location and frequency of cracks; and

.1.2 location of buckles. 3.2.1.2 This information may be found in the survey reports and/or the owner's files, including the results of the owner's own inspections. The defects should be analysed, noted and marked on sketches.



3.2.1.3 In addition, general experience should be utilized. For example, reference should be made to reference 1, which contains a catalogue of typical damages and proposed repair methods for various tanker structural details. 3.2.1.4 Such figures should be used together with a review of the main drawings, in order to compare with the actual structure and search for similar details which may be susceptible to damage. An example is shown in figure 2. In particular, chapter 3 of reference 1 deals with various aspects specific to double hull tankers, such as stress concentration locations, misalignment during construction, corrosion trends, fatigue considerations and areas requiring special attention, which should be considered in working out the survey planning. 3.2.1.5 The review of the main structural drawings, in addition to using the above-mentioned figures, should include checking for typical design details where cracking has been experienced. The factors contributing to damage should be carefully considered. 3.2.1.6 The use of HTS is an important factor. Details showing good service experience where ordinary, mild steel has been used may be more susceptible to damage when HTS, and its higher associated stresses, are utilized. There is extensive and, in general, good experience, with the use of HTS for longitudinal material in deck and bottom structures. Experience in other locations, where the dynamic stresses may be higher, is less favourable, e.g. side structures. 3.2.1.7 In this respect, stress calculations of typical and important components and details, in accordance with relevant methods, may prove useful and should be considered. 3.2.1.8 The selected areas of the structure identified during this process should be recorded and marked on the structural drawings to be included in the survey programme. 3.2.2 Corrosion 3.2.2.1 In order to evaluate relative corrosion risks, the following information is generally to be considered: .1.1 usage of tanks and spaces;

.1.2 condition of coatings; .1.3 condition of anodes; .1.4 cleaning procedures;

.1.5 previous corrosion damage; .1.6 ballast use and time for cargo tanks; .1.7 corrosion risk scheme (see reference 2, table 2.1); and .1.8 location of heated tanks.


Page 99


3.2.2.2 Reference 2 gives definitive examples which can be used for judging and describing coating condition, using typical pictures of conditions. 3.2.2.3 The evaluation of corrosion risks should be based on information in reference 2, together with the age of the ship and relevant information on the anticipated condition as derived from the information collected in order to prepare the survey programme. 3.2.2.4 The various tanks and spaces should be listed with the corrosion risks nominated accordingly. Special attention should be given to the areas where the double hull tanker is particularly exposed to corrosion. To this end, the specific aspects addressing corrosion in double hull tankers indicated in 3.4 (Corrosion trends) of reference 1 should be taken into account. 3.2.3 Locations for close-up survey and thickness measurement 3.2.3.1 On the basis of the table of corrosion risks and the evaluation of design experience, the locations for initial close-up survey and thickness measurement (sections) may be nominated. 3.2.3.2 The sections subject to thickness measurement should normally be nominated in tanks and spaces where corrosion risk is judged to be the highest. 3.2.3.3 The nomination of tanks and spaces for close-up survey should, initially, be based on highest corrosion risk and should always include ballast tanks. The principle for the selection should be that the extent is increased by age or where information is insufficient or unreliable.

ANNEX 12

CRITERIA FOR LONGITUDINAL STRENGTH OF HULL GIRDER FOR OIL TANKERS

1 General 1.1 These criteria should be used for the evaluation of the longitudinal strength of the ship�s hull girder as required by 8.1.2. 1.2 In order that the ship�s longitudinal strength to be evaluated can be recognized as valid, fillet welding between longitudinal internal members and hull envelopes should be in sound condition so as to keep the integrity of longitudinal internal members with hull envelopes. 2 Evaluation of longitudinal strength On oil tankers of 130 m in length and upwards and over 10 years of age, the longitudinal strength of the ship�s hull girder should be evaluated in compliance with the requirements of this annex on the basis of the thickness measured, renewed or reinforced, as appropriate, during the renewal survey of the Cargo Ship Safety Construction Certificate or Cargo Ship Safety Certificate (SC renewal survey). The condition of the hull girder for longitudinal strength evaluation should be determined in accordance with the methods specified in appendix 3. 2.1 Calculation of transverse sectional areas of deck and bottom flanges of hull

girder 2.1.1 The transverse sectional areas of deck flange (deck plating and deck longitudinals) and bottom flange (bottom shell plating and bottom longitudinals) of the ship�s hull girder should be calculated by using the thickness measured, renewed or reinforced, as appropriate, during the SC renewal survey. 2.1.2 If the diminution of sectional areas of either deck or bottom flange exceeds 10% of their respective as-built area (i.e., original sectional area when the ship was built), either one of the following measures should be taken:

.1 to renew or reinforce the deck or bottom flanges so that the actual sectional area is not less than 90% of the as-built area; or

.2 to calculate the actual section of moduli (Zact) of transverse section of the

ship�s hull girder by applying the calculation method specified in appendix 1, by using the thickness measured, renewed or reinforced, as appropriate, during the SC renewal survey.


Page 103


2.2 Requirements for transverse section modulus of hull girder 2.2.1 The actual section moduli of the transverse section of the ship�s hull girder, calculated in accordance with paragraph 2.1.2.2, should satisfy either of the following provisions, as applicable:

.1 for ships constructed on or after 1 July 2002, the actual section moduli (Zact) of the transverse section of the ship�s hull girder calculated in accordance with the requirements of paragraph 2.1.2.2 should be not less than the diminution limits determined by the Administration, taking into account the recommendations adopted by the Organization;*or

.2 for ships constructed before 1 July 2002, the actual section moduli (Zact) of

the transverse section of the ship�s hull girder calculated in accordance with the requirements of paragraph 2.1.2.2 should meet the criteria for minimum section modulus for ships in service required by the Administration or recognized classification society, provided that in no case Zact should be less than the diminution limit of the minimum section modulus (Zmc) as specified in appendix 2.

Appendix 1

Calculation criteria of section moduli of midship section of hull girder 1 When calculating the transverse section modulus of the ship�s hull girder, the sectional area of all continuous longitudinal strength members should be taken into account. 2 Large openings, i.e. openings exceeding 2.5 m in length or 1.2 m in breadth, and scallops, where scallop welding is applied, are always to be deducted from the sectional areas used in the section modulus calculation. 3 Smaller openings (manholes, lightening holes, single scallops in way of seams, etc.) need not be deducted, provided that the sum of their breadths or shadow area breadths in one transverse section does not reduce the section modulus at deck or bottom by more than 3% and provided that he height of lightening holes, draining holes and single scallops in longitudinals or longitudinal girders does not exceed 25% of the web depth, for scallops maximum 75 mm. 4 A deduction-free sum of smaller opening breadths in one transverse section in the bottom or deck area of 0.06 (B � Σb) (where B = breadth of ship, Σb = total breadth of large openings) may be considered equivalent to the above reduction in sectional modulus. 5 The shadow area will be obtained by drawing two tangent lines with an opening angle of 30°.

* Refer to resolution MSC.108(73) on Recommendation on compliance with the requirements of

paragraph 2.2.1.1 of annex 12 to annex B to resolution A.744(18).



6 The deck modulus is related to the moulded deck line at side. 7 The bottom modulus is related to the base line. 8 Continuous trunks and longitudinal hatch coamings should be included in the longitudinal sectional area provided they are effectively supported by longitudinal bulkheads or deep girders. The deck modulus is then to be calculated by dividing the moment of inertia by the following distance, provided this is greater than the distance to the deck line at side:

where: y = distance from neutral axis to top of continuous strength member; x = distance from top of continuous strength member to centreline of the ship; x and y to be measured to the point giving the largest value of yt . 9 Longitudinal girders between multi-hatchways will be considered by special calculations.

Appendix 2

Diminution limit of minimum longitudinal strength of ships in service

1 The diminution limit of the minimum section modulus (Zmc) of oil tankers in service is given by the following formula: Zmc = cL2 B (Cb + 0.7)k (cm3) where:

L = Length of ship. L is the distance, in metres, on the summer load waterline from the fore side of stem to the after side of the rudder post, or the centre of the rudder stock if there is no rudder post. L is not to be less than 96%, and need not be greater than 97%, of the extreme length on the summer load waterline. In ships with unusual stern and bow arrangement, the length L may be specially considered.

B = Greatest moulded breadth in metres.

k = 0.72 for high-tensile steel with yield stress of 355 N/mm2 and over. 2 Scantlings of all continuous longitudinal members of the ship�s hull girder based on the section modulus requirement in 1 above should be maintained within 0.4L amidships. However, in special cases, based on consideration of type of ship, hull form and loading conditions, the scantlings may be gradually reduced towards the end of 0.4L part, bearing in mind the desire not to inhibit the ship�s loading flexibility. 3 However, the above standard may not be applicable to ships of unusual type or design, e.g., for ships of unusual main proportions and/or weight distributions.

Appendix 3

Sampling method of thickness measurements for longitudinal strength evaluation and repair methods

1 Extent of longitudinal strength evaluation Longitudinal strength should be evaluated within 0.4L amidships for the extent of the hull girder length that contains tanks therein and within 0.5L amidships for adjacent tanks which may extend beyond 0.4L amidships, where tanks means ballast tanks and cargo tanks.

2 Sampling method of thickness measurement 2.1 Pursuant to the requirements of section 2.5, transverse sections should be chosen such that thickness measurements can be taken for as many different tanks in corrosive environments as possible, e.g. ballast tanks sharing a common plane boundary with cargo tanks fitted with heating coils, other ballast tanks, cargo tanks permitted to be filled with sea water and other cargo tanks. Ballast tanks sharing a common plane boundary with cargo tanks fitted with heating coils and cargo tanks permitted to be filled with sea water should be selected where present. 2.2 The minimum number of transverse sections to be sampled should be in accordance with annex 2. The transverse sections should be located where the largest thickness reductions are suspected to occur or are revealed from deck and bottom plating measurements prescribed in 2.3 and should be clear of areas which have been locally renewed or reinforced. 2.3 At least two points should be measured on each deck plate and/or bottom shell plate required to be measured within the cargo area in accordance with the requirements of annex 2. 2.4 Within 0.1D (where D is the ship�s moulded depth) of the deck and bottom at each transverse section to be measured in accordance with the requirements of annex 2, every longitudinal and girder should be measured on the web and face plate, and every plate should be measured at one point between longitudinals. 2.5 For longitudinal members other than those specified in 2.4 to be measured at each transverse section in accordance with the requirements of annex 2, every longitudinal and girder should be measured on the web and face plate, and every plate should be measured at least in one point per strake. 2.6 The thickness of each component should be determined by averaging all of the measurements taken in way of the transverse section on each component. 3 Additional measurements where the longitudinal strength is deficient 3.1 Where one or more of the transverse sections are found to be deficient in respect of the longitudinal strength requirements given in this annex, the number of transverse sections for thickness measurement should be increased such that each tank within the 0.5L amidships region has been sampled. Tank spaces that are partially within, but extend beyond, the 0.5L region, should be sampled. 3.2 Additional thickness measurements should also be performed on one transverse section forward and one aft of each repaired area to the extent necessary to ensure that the areas bordering the repaired section also comply with the requirements of the Guidelines. 4 Effective repair methods 4.1 The extent of renewal or reinforcement carried out to comply with this annex should be in accordance with 4.2.


Page 107


4.2 The minimum continuous length of a renewed or reinforced structural member should be not less than twice the spacing of the primary members in way. In addition, the thickness diminution in way of the butt joint of each joining member forward and aft of the replaced member (plates, stiffeners, girder webs and flanges, etc.) should not be within the substantial corrosion range (75% of the allowable diminution associated with each particular member). Where differences in thickness at the butt joint exceed 15% of the lower thickness, a transition taper should be provided. 4.3 Alternative repair methods involving the fitting of straps or structural member modification should be subject to special consideration. In considering the fitting of straps, it should be limited to the following conditions: .1 to restore and/or increase longitudinal strength;

.2 the thickness diminution of the deck or bottom plating to be reinforced should not be within the substantial corrosion range (75% of the allowable diminution associated with the deck plating);

.3 the alignment and arrangement, including the termination of the straps, is

in accordance with a standard recognized by the Administration;

.4 the straps are continuous over the entire 0.5L amidships length; and

.5 continuous fillet welding and full penetration welds are used at butt welding and, depending on the width of the strap, slot welds. The welding procedures applied should be acceptable to the Administration.

4.4 The existing structure adjacent to replacement areas and in conjunction with the fitted straps, etc. should be capable of withstanding the applied loads, taking into account the buckling resistance and the condition of welds between the longitudinal members and hull envelope plating.�

68 Paragraph 5.1.4 is deleted, and paragraphs 5.1.5 and 5.1.6 are renumbered as 5.1.4 and 5.1.5. 69 The following new paragraphs 5.2.1.1 to 5.2.1.3 are added after existing paragraph 5.2.1:

�5.2.1.1 In order to enable the attending surveyors to carry out the survey, provisions for proper and safe access should be agreed between the owner and the Administration. 5.2.1.2 Details of the means of access should be provided in the survey planning questionnaire. 5.2.1.3 In cases where the provisions of safety and required access are judged by the attending surveyors not to be adequate, the survey of the spaces involved should not proceed.�

70 Existing paragraphs 5.2.2 to 5.2.4 are replaced by the following:

�5.2.2 Tanks and spaces should be safe for access. Tanks and spaces should be gas free and properly ventilated. Prior to entering tank, void or enclosed space, it should be verified that the atmosphere in that space is free from hazardous gas and contains sufficient oxygen.

5.2.3 Tanks and spaces should be sufficiently clean and free from water, scale, dirt, oil residues, sediments etc., to reveal corrosion, deformation, fractures, damages or other structural deterioration as well as the condition of the coating. In particular this applies to areas which are subject to thickness measurements.�

5.2.4 Sufficient illumination should be provided to reveal corrosion, deformation, fractures, damages or other structural deterioration as well as the condition of the coating.�

71 The following new paragraphs 5.2.5 and 5.2.6 are added:

�5.2.5 The surveyor(s) should always be accompanied by at least one responsible person, assigned by the owner, experienced in tank and enclosed spaces inspection. In addition a backup team of at least two experienced persons should be stationed at the hatch opening of the tank or space that is being surveyed. The back-up team should continuously observe the work in the tank or space and should keep lifesaving and evacuation equipment ready for use.�

5.2.6 A communication system should be arranged between the survey party in the tank or space being examined, the responsible officer on deck and, as the case may be, the navigation bridge. The communication arrangements should be maintained throughout the survey.�

72 In existing paragraph 5.3.2, between the fourth and fifth sub-items, a new sub-item �portable ladders� is inserted. 73 The six sub-items in paragraph 5.3.2 are numbered from �.1� to �.6� and the five sub-items in paragraph 5.4.2 are numbered from �.1� to �.5�.



74 New paragraphs 5.4.3 to 5.4.5 are added as follows:

�5.4.3 Explosimeter, oxygen-meter, breathing apparatus, lifelines, riding belts with rope and hook and whistles together with instructions and guidance on their use should be made available during the survey. A safety check-list should be provided.

5.4.4 Adequate and safe lighting should be provided for the safe and efficient conduct of the survey.

5.4.5 Adequate protective clothing should be made available and used (e.g. safety helmet, gloves, safety shoes, etc) during the survey.�

75 The existing paragraph 5.5.3 is deleted and the existing paragraph 5.5.4 is renumbered as 5.5.3. 76 The following new paragraphs 5.5.4 to 5.5.7 are added:

�5.5.4 When rafts or boats will be used for close-up survey the following conditions should be observed:

.1 only rough duty, inflatable rafts or boats, having satisfactory residual

buoyancy and stability even if one chamber is ruptured, should be used; .2 the boat or raft should be tethered to the access ladder and an additional


.3 appropriate lifejackets should be available for all participants; .4 the surface of water in the tank should be calm (under all foreseeable

conditions the expected rise of water within the tank should not exceed 0.25 m) and the water level either stationary or falling. On no account should the level of the water be rising while the boat or raft is in use;

.5 the tank or space must contain clean ballast water only. Even a thin sheen

of oil on the water is not acceptable;

.6 at no time should the water level be allowed to be within 1 m of the deepest under deck web face flat so that the survey team is not isolated from a direct escape route to the tank hatch. Filling to levels above the deck transverses should only be contemplated if a deck access manhole is fitted and open in the bay being examined, so that an escape route for the survey party is available at all times. Other effective means of escape to the deck may be considered;

.7 if the tanks (or spaces) are connected by a common venting system, or

Inert Gas system, the tank in which the boat or raft should be used should be isolated to prevent a transfer of gas from other tanks (or spaces).

5.5.5 Rafts or boats alone may be allowed for inspection of the under deck areas for tanks or spaces if the depth of the webs is 1.5 m or less.


Page 113


5.5.6 If the depth of the webs is more than 1.5 m, rafts or boats alone may be allowed only:

.1 when the coating of the under deck structure is in GOOD condition and

there is no evidence of wastage; or

.2 if a permanent means of access is provided in each bay to allow safe entry and exit. This means of access should be direct from the deck via a vertical ladder with a small platform fitted approximately 2 m below the deck. Other effective means of escape to the deck may be considered.

If neither of the above conditions are met, then staging or other equivalent means should be provided for the survey of the under deck areas.

5.5.7 The use of rafts or boats alone in 5.5.5 and 5.5.6 does not preclude the use of boats or rafts to move about within a tank during a survey.�

77 The following new section 5.6 is added:

�5.6 Survey planning meeting

5.6.1 Proper preparation and close co-operation between the attending surveyor(s) and the owner�s representatives onboard prior to and during the survey are an essential part in the safe and efficient conduct of the survey. During the survey on board safety meetings should be held regularly.

5.6.2 Prior to commencement of any part of the renewal and intermediate survey, a survey planning meeting should be held between the attending surveyor(s), the owner�s representative in attendance, the thickness measurement company operator (as applicable) and the master of the ship for the purpose to ascertain that all the arrangements envisaged in the survey programme are in place, so as to ensure the safe and efficient conduct of the survey work to be carried out.


.1 schedule of the vessel (i.e. the voyage, docking and undocking

manoeuvres, periods alongside, cargo and ballast operations etc.);

.2 provisions and arrangements for thickness measurements (i.e. access, cleaning/de-scaling, illumination, ventilation, personal safety);



.5 extent of close-up survey and thickness measurement considering the

coating condition and suspect areas/areas of substantial corrosion;




.7 taking representative readings in general and where uneven

corrosion/pitting is found;

.8 mapping of areas of substantial corrosion;

.9 communication between attending surveyor(s) the thickness measurement company operator(s) and owner representative(s) concerning findings.�
