Rules and Regulations for the Classification of aFloating Offshore Installation at a Fixed Location

Introduction

The Rules are published as a complete set, individual Parts are,however, available on request. A comprehensive List of Contentsis placed at the beginning of each Part.

Numbering and Cross-References

A decimal notation system has been adopted throughout. Fivesets of digits cover the divisions, i.e. Part, Chapter, Section, sub-Section and paragraph. The textual cross-referencing within thetext is as follows, although the right hand digits may be addedor omitted depending on the degree of precision required: (a) In same Chapter, e.g. see 2.1.3 (i.e. down to paragraph).(b) In same Part but different Chapter, e.g. see Ch 3,2.1 (i.e.

down to sub-Section).(c) In another Part, e.g. see Pt 2, Ch 1,3 (i.e. down to Section).

The cross-referencing for Figures and Tables is as follows:(a) In same Chapter, e.g. as shown in Fig 2.3.5 (i.e. Chapter,

Section and Figure Number). (b) In same Part but different Chapter, e.g. as shown in Fig. 2.3.5

in Chapter 2.(c) In another Part, e.g. see Table 2.7.1 in Pt 3, Ch 2.

Rules updating

The Rules are generally published regularly and changed througha system of Notices. Subscribers are forwarded copies of suchNotices when the Rules change.

Current changes to Rules that appeared in Notices are shownwith a black rule alongside the amended paragraph on the lefthand side. A solid black rule indicates amendments and a dotted black rule indicates corrigenda. A dot-dash line indicateschanges necessitated by International Conventions, Code ofPractice or IACS Unified Requirements.

Rules programs

LR has developed calculation software for floating offshoreinstallations. For details of this software please contact LR.

Direct calculations

The Rules require direct calculations to be submitted for specific parts of the unit structure or arrangements and these willbe assessed in relation to LRs own direct calculation procedures. They may also be required for units of unusual form,proportion or speed, or for special restricted service and as sup-porting documentation for arrangements or scantlings alterna-tive to those required by the Rules.

UPDATE NOTES

1. The April 2008 version of these Rules and Regulations incorporates those changes contained in the Notices to the May 1999 version.

2. Changes approved by the Board and the General Committee in 2007/2008.

3. Editorial amendments have also been incorporated.

4. The April 2008 version of these Rules and Regulations supersedes the May 1999 version.

CLASSIFICATION

The following explanatory note is offered to assist those concerned in the application of these Rules and Regulations.

Explanatory Note

Unit classification may be regarded as the development and worldwide implementation of published Rules and Regulations which,in conjunction with proper care and conduct on the part of the Owner and operator, will provide for:

1. the structural strength of (and where necessary the watertight integrity of) all essential parts of the hull and itsappendages;

2. the safety and reliability of the propulsion and steering systems; and

3. the effectiveness of those other features and auxiliary systems which have been built into the unit in order to establishand maintain basic conditions on board whereby appropriate cargoes and personnel can be safely carried whilst the unitis at sea, at anchor, or moored in harbour.

Lloyd's Register (LR) maintains these provisions by way of the periodical visits by its Surveyors to the unit as defined in theRegulations in order to ascertain that the vessel currently complies with those Rules and Regulations. Should significant defectsbecome apparent or damages be sustained between the relevant visits by the Surveyors, the Owner and operator are required toinform LR without delay. Similarly any modification which would affect Class must receive prior approval by LR.

A unit is said to be in Class when the Rules and Regulations which pertain to it have, in the opinion of LR, been complied with, orwhen special dispensation from compliance has been granted by LR.

It should be appreciated that, in general, classification Rules and Regulations do not cover such matters as the unit's floatationalstability, life-saving appliances, pollution prevention arrangements, and structural fire protection, detection and extinctionarrangements where these are covered by the International Convention for the Safety of Life at Sea, 1974, its Protocol of 1978,and the amendments thereto, nor do they protect personnel on board from dangers connected with their own actions ormovement around the unit. This is because the handling of these aspects is the prerogative of the National Authority with whichthe unit is registered. A great many of these authorities, however, delegate such responsibilities to the Classification Societies whothen undertake them in accordance with agreed procedures.

Section 7

7.1 The Committee has power to adopt, and publish as deemed necessary, Rules relating to classification and has (in relation thereto) provided the following:(a) Except in the case of a special directive by the Committee, no new Regulation or alteration to any existing Regulation relat-

ing to character of classification or to class notations is to be applied to existing ships.(b) Except in the case of a special directive by the Committee, or where changes necessitated by mandatory implementation of

International Conventions, Codes or Unified Requirements adopted by the International Association of Classification Societiesare concerned, no new Rule or alteration in any existing Rule is to be applied compulsorily after the date on which the contractbetween the ship builder and ship owner for construction of the ship has been signed, nor within six months of its adoption.The date of contract for construction of a ship is the date on which the contract to build the ship is signed between theprospective ship owner and the ship builder. This date and the construction number (i.e hull numbers) of all the vesselsincluded in the contract are to be declared to the Committee by the party applying for the assignment of class to a newbuild-ing. The date of contract for construction of a series of sister ships, including specified optional ships for which the optionis ultimately exercised, is the date on which the contract to build the series is signed between the prospective ship owner andthe ship builder. In this section a series of sister ships is a series of ships built to the same approved plans for classificationpurposes, under a single contract for construction. The optional ships will be considered part of the same series of sisterships if the option is exercised not later than 1 year after the contract to build the series was signed. If a contract for construc-tion is later amended to include additional ships or additional options, the date of contract for construction for such shipsis the date on which the amendment to the contract is signed between the prospective ship owner and the ship builder. Theamendment to the contract is to be considered as a new contract. If a contract for construction is amended to change theship type, the date of contract for construction of this modified vessel, or vessels, is the date on which the revised contractor new contract is signed between the Owner, or Owners, and the shipbuilder. Where it is desired to use existing approvedship or machinery plans for a new contract, written application is to be made to the Committee.NOTESister ships may have minor design alterations provided that such alterations do not affect matters related to classification.

(c) All reports of survey are to be made by Surveyors authorised by LR to survey and report (hereinafter referred as the Surveyors)according to the form prescribed, and submitted for the consideration of the Committee, or its Sub-Committee ofClassification, but the character assigned by the latter is to be subject to confirmation by the Committee or by the Chairmanacting on behalf of the Committee.

(d) Information contained in the reports of classification and statutory surveys will be made available to the relevant owner,National Administration, Port State Administration, P&I Club, hull underwriter and, if authorized in writing by that owner, toany other person or organization.

(e) Information relating to the status of classification and statutory surveys and suspensions/withdrawals of class together withany associated conditions of class will be made available as required by applicable legislation or court order.

(f) Notwithstanding the general duty of confidentiality owed by LR to its clients, LR will participate fully in the IACS Early WarningSystem which requires each IACS member to provide its fellow IACS members with information on serious hull structuraland engineering systems failures, including the name of the ship and its IMO number, to enable such useful information tobe shared and utilised to facilitate the proper working of the IACS Early Warning System (which is aimed at enabling (i) sisteror similar ships to avoid similar problems and (ii) the shipping industry generally to learn from failures and mistakes).

(g) A Classification Executive consisting of senior members of LRs Classification Department staff shall carry out whatever dutiesthat may be within the function of the Sub-Committee of Classification that the Sub-Committee of Classification assigns to it.

Section 8

8.1 No Lloyds Register Group employee is permitted under any circumstances, to accept, directly or indirectly, from anyperson, firm or company, with whom the work of the employee brings the employee into contact, any present, bonus, enter-tainment or honorarium of any sort whatsoever which is of more than nominal value or which might be construed to exceedcustomary courtesy extended in accordance with accepted ethical business standards.

Section 9

9.1 The Committee has power to:(a) determine the amounts to be charged for the services provided by LR or for any of its publications;(b) withhold or, if already granted, to suspend or withdraw any class (or to withhold any certificate or report in any other case),

in the event of non-payment of any fee.

Section 10

10.1 In this section:(i) Services means the services provided by LR; and(ii) Contract means the contract for supply of the Services; and(iii) the LR Group includes LR, its affiliates and subsidiaries, and the officers, directors, employees, representatives and agents

of any of them, individually or collectively.

10.2 LRs services do not assess compliance with any standard other than the applicable LR Rules, international conventions,and other standards agreed in writing by LR and the Client.

10.3 In providing Services, information or advice, the LR Group does not warrant the accuracy of any information or advicesupplied. Except as set out herein, the LR Group will not be liable for any loss, damage or expense sustained by any person andcaused by any act, omission, error, negligence or strict liability of any of the LR Group or caused by any inaccuracy in any information or advice given in any way by or on behalf of the LR Group even if held to amount to a breach of warranty.Nevertheless, if the Client uses LR's Services or relies on any information or advice given by or on behalf of the LR Group and as aresult suffers loss, damage or expense that is proved to have been caused by any negligent act, omission or error of the LR Groupor any negligent inaccuracy in information or advice given by or on behalf of the LR Group, then LR will pay compensation to theClient for its proved loss up to but not exceeding the amount of the fee (if any) charged for that particular service, information oradvice.

10.4 Notwithstanding the previous clause, the LR Group will not be liable for any loss of profit, loss of contract, loss of useror any indirect or consequential loss, damage or expense sustained by any person caused by any act, omission or error or causedby any inaccuracy in any information or advice given in any way by or on behalf of the LR Group even if held to amount to abreach of warranty.

10.5 LRs omission or failure to carry out or observe any stipulation, condition, or obligation to be performed under theContract will not give rise to any claim against LR or be deemed to be a breach of contract if the failure or omission arises fromcauses beyond LRs reasonable control.

10.6 Any dispute about the Services or the Contract is subject to the exclusive jurisdiction of the English courts and will begoverned by English law.

1.1.2 A floating offshore installation operating at a fixedgeographic location and built in accordance with LloydsRegisters (hereinafter referred to as LR) Rules andRegulations or in accordance with requirements equivalentthereto, will be assigned a class on the ClassDirect Livewebsite and will continue to be classed so long as they arefound, upon examination at the prescribed surveys, to bemaintained in accordance with the requirements of the Rules.Classification will be conditional upon compliance with LRsrequirements for materials, structure, machinery, equipmentand other safety considerations.

1.1.3 The basic LR class notation for the installationwould normally include: Description of the installation, facilities provided

and field location. Structure and marine systems. Positional mooring system. Propulsion (where applicable)Process facilities are not required to be classed, however, anoptional class notation PPPF (process plant facility) can beassigned at the request of the owner (see 2.4.9). Detaileddesign, procurement, construction, site integration andcommissioning activities regarding topsides facilities aretypically subjected to certification by LR to recognisednational and international codes, or equivalent engineeringstandards. Alternatively, the topsides could be subject toverification to an agreed written scheme. These facilities willbe installed on a vessel with a LR classed hull, marine systemsand mooring system. Certification or verification of thetopsides facilities is the minimum requirement for assignmentof an LR class notation for a complete floating offshoreinstallation. Other optional class notations are also given inSection 2.

Classification Regulations

1.1.4 Installations designed and constructed to standardsother than the Rule requirements will be considered forclassification subject to the alternative standards beingconsidered by LR to give an equivalent level of safety to theRule requirements. It is essential that in such cases LR isinformed of the Owners proposals at an early stage in orderthat a basis for acceptance of the standards may be agreed.

1.1.5 As an option, the Owner may request LR toconsider performance standards determined by riskassessment as the basis for design, construction, andinspection/maintenance. Guidelines for classification of anoffshore installation using risk assessment to determineperformance standards are provided in Part 1A. Definitions ofrisk assessment terms are also given in Part 1A. Performancestandards determined by risk assessment may be accepted byLR as the alternative basis for classification, provided that: LR approval is obtained at all key stages detailed in Part

1A; and LR verifies that all elements which are critical to the

safety and integrity of the installation meet their requiredperformance standards, as outlined in Part 1A.

Where a Formal Safety Assessment or Safety Case is preparedas a requirement of a National Administration or of theOwner, the Owner may request LR to consider the results as abasis for determining the performance standards to be usedfor classification. In such cases, the Formal Safety Assessmentor Safety Case will be reviewed by LR to confirm that itconsiders all hazards to the safety and integrity of theinstallation which are relevant to classification. The Guidelinesin Part 1A will then apply.

1.1.6 The Committee, in addition to requiringcompliance with LRs Rules, or other agreed performancestandards, may require to be satisfied that units are suitablefor geographical or other limits or conditions of the servicecontemplated.

1.1.7 Although the specified design environmentalcriteria on which classification is based is the responsibility ofthe Owner, assessment of an installations suitability forservice at a particular offshore location will be undertakenand agreed by LR.

1.1.8 Loading conditions and any other preparationsrequired to permit a unit (whether self-propelled or not) witha class notation specifying some service limitation toundertake a sea-going voyage, either from port of buildingto an offshore location or from one location to another, areto be in accordance with arrangements agreed by LR prior tothe voyage.

1.1.9 Any damage, defect, breakdown or grounding,which could invalidate the conditions for which class hasbeen assigned, is to be reported to LR without delay.

1.1.10 The Owner is solely responsible for the operation ofthe unit. The Rules are framed on the understanding that theunit wil l be properly loaded and operated, and theenvironmental conditions are no more severe than thoseagreed for the design basis and approval, without prioragreement of LR.

1.1.16 Where an on-board computer system havinglongitudinal strength computation capability, which isrequired by the Rules, is provided on a new unit or newlyinstalled on an existing unit, then the system is to be certifiedin respect of longitudinal strength in accordance with LRsApproval of Longitudinal Strength and Stability CalculationPrograms.

1.1.17 Where an onboard computer system having stability computation capability is provided on a new unit,then the system is to be certified in respect of stability aspectsin accordance with LR's document entitled, Approval ofLongitudinal Strength and Stability Calculation Programs.When provided, an onboard computer system having stabilitycomputation capability is to carry out the calculations andchecks necessary to assess compliance with all the stabilityrequirements applicable to the unit on which it is installed.

1.1.18 Self-elevating units as defined in Section 2 willnormally be assigned class in accordance with LRs Rules andRegulations for the Classification of Mobile Offshore Units(hereinafter referred to as the Rules for Mobile OffshoreUnits), but when the unit is intended to operate permanentlyat a fixed location for its service life class may be assigned inaccordance with these Rules.

1.1.19 When a unit fitted with a conventional rudder is tooperate at a fixed location, it is the Owners responsibility toensure that suitable arrangements are provided to preventdamage to the steering gear and propelling machinery.Special consideration will be given by LR to the requirementsfor the steering gear and propelling machinery, see Pt 4, Ch11 and Pt 5, Ch 18 and Ch 5.

1974 and its Protocol of 1978, International Convention for the Prevention of Pollution

from Ships, 1973, as modified by the Protocol of 1978relating thereto,

and applicable Amendments thereto, the Committee requiresthe applicable Convention Certificates to be issued by aNational Administration, or by LR, or by an IACS Memberwhen so authorized. Safety Management Certificates inaccordance with the provisions of the International SafetyManagement Code (ISM Code) may be issued by an organization complying with IMO Resolution A.739(18) andauthorized by the National Administration with which theunit is registered. Cargo Ship Radio Certificates may be issuedby an organization authorized by the National Administrationwith which the unit is registered. In the case of dual classedunits, Convention Certificates may be issued by the otherSociety with which the unit is classed provided this isrecognized in a formal Dual Class Agreement with LR andprovided the other Society is also authorized by the NationalAdministration. In the event of a National Administrationwithdrawing any units Convention Certificate (referred to inthis Section) then the committee may suspend the units class.However if a unit is removed from the NationalAdministrations Registry then the committee will suspend theunits class. In the event of ISM Code certification beingwithdrawn from a unit or Operator then the Committee willsuspend the units class.

1.1.14 For units which are outside the scope of applicationof the 2001 MODU Code and/or the internationalConventions referred to in 1.1.13 above, then compliancewith any prescribed standards of the applicable Coastal StateAuthority is to be demonstrated by the issue of appropriatecertification by that Coastal State Authority or LR where soauthorized.

1.1.15 Where National Administrations have no prescribedstandards for units which are outside of the scope of

1.2.2 In many instances these rules require that particularcomponents, systems and equipment etc. must also complywith applicable sections of the Rules for Ships. Every effort hasbeen made to avoid potential conflicting requirements,however, where such a conflict becomes apparent therequirements of these Rules shall take precedence.

1.3 Advisory services

1.3.1 The Rules do not cover certain technicalcharacteristics, such as stability, trim, hull vibration, etc., butthe Committee is willing to advise on such matters althoughit cannot assume responsibility for them.

1.3.2 Where a unit is so badly damaged that class has tobe suspended, LR is prepared to assist the Owner with adviceif requested.

1.4 Legislative verification

1.4.1 LR has been authorized by a number of NationalAdministrations to carry out verification of offshore units andinstallations in accordance with statutory Regulations. Fulldetails will be supplied to Owners and other interested partieson request. (See also 2.7 and 2.8.3).

If, as a result of such survey, the structure,equipment and machinery be reported in all respects freefrom deterioration, the subsequent Special Survey andComplete Survey of the machinery will date from the time ofsuch examination.

3.3 Existing installations

3.3.1 Classification of units not built under survey. Therequirements of the Committee for the classification of unitswhich have not been built under LRs Survey are indicated inCh 3,19. Special consideration will be given to unitstransferring class to LR from another recognized ClassificationSociety.

3.3.2 Reclassification. When reclassification or classreinstatement is desired for an installation for which the classpreviously assigned by LR has been withdrawn or suspended,the Committee will direct that a survey appropriate to the ageof the installation and the circumstances of the case, becarried out by LRs Surveyors. If, at such survey, theinstallation is found to be or is placed in a good and efficientcondition in accordance with the requirements of the Rulesand Regulations, the Committee will be prepared to considerreinstatement of the original class or the assignment of suchother class as may be deemed necessary.

3.3.3 The Committee reserves the right to decline anapplication for classification or reclassification where the priorhistory or condition of the installation indicates this to beappropriate.

3.4 Damages, repairs and alterations

3.4.1 All repairs to hull/structure, equipment, machineryand drilling/process plant which may be required in order thatan installation may retain its class, see 1.1.9, are to be carriedout to the satisfaction of LRs Surveyors. Alternatively, theCommittee may agree, in exceptional cases that qualitycontrol can be enforced by the Owner or repairer, on site, inwhich case the repairs are to be surveyed by LRs Surveyors atthe earliest opportunity thereafter.

3.4.2 When at any survey the Surveyors consider repairsto be immediately necessary, either as a result of damage, orwear and tear, they are to communicate theirrecommendations at once to the Owner, or hisrepresentative. When such recommendations are notcomplied with, immediate notification is to be given to theCommittee by the Surveyors.

3.4.3 When at any survey it is found that any damage,defect or breakdown (see 1.1.9) is of such a nature that doesnot require immediate permanent repair, but is sufficientlyserious to require rectification by a prescribed date in order tomaintain class, a suitable condition of class is to be imposedby the Surveyors and recommended to the Committee forconsideration.

3.4.4 If a unit which is classed with LR as an installation isdamaged to such an extent as to necessitate towage whilstin a damaged condition to a suitable repair facility, it shall bethe Owners responsibility to notify LR at the first practicableopportunity.

3.4.5 Plans and particulars of any proposed alterations tothe approved scantlings and arrangements of hull/structure,equipment, machinery or drilling/process plant are to besubmitted for approval, and such alterations are to be carriedout to the satisfaction of LRs Surveyors.

3.5 Existing installations Periodical Surveys

3.5.1 Annual Surveys are to be held on all installationswithin three months, before or after each anniversary of thecompletion, commissioning or Special Survey in accordancewith the requirements given in Chapter 3. The date of thelast Annual Survey will be recorded on the ClassDirect Livewebsite.

3.5.2 Intermediate Surveys are to be held on allinstallations instead of the second or third Annual Surveyafter completion, commissioning or Special Survey inaccordance with the requirements given in Ch 3,3. TheIntermediate Survey maybe commenced at the second AnnualSurvey and progressed with completion at the third AnnualSurvey. The date of the last Intermediate Survey will berecorded on the ClassDirect Live website.

3.5.3 The Owner should notify LR whenever a unit whichis classed as an installation can be examined in dry-dock.Units are to be examined in dry-dock in accordance with Ch3,4. The Committee will accept In-water Surveys in lieu ofDocking Surveys on installations assigned an OOIWS (In-waterSurvey) notation, see Ch 3,4.3. The frequency of DockingSurveys and In-water Surveys are to be in accordance with3.5.4.

3.5.4 The underwater parts of an installation are to beexamined in dry-dock or by an In-water Survey at intervals of21/2 years but the survey may be held within six months eitherside of the due date provided the maximum period betweenDockings Surveys or In-water Surveys in lieu of DockingSurveys and the Special Survey required by 3.5.9 does notexceed three years.

3.5.5 One of the two Docking Surveys or In-waterSurveys in lieu of Docking Surveys required in each five yearperiod is to coincide with the Special Survey, see 3.5.9.Consideration may be given in exceptional circumstances toan extension of this interval not exceeding three monthsbeyond the due date. In this context exceptionalcircumstances means unavailability of dry-docking facilities,repair facilities, essential materials, equipment or spare partsor delays incurred by action taken to avoid severe weatherconditions.

3.5.6 The date of the last examination in dry-dock or In-water Survey will be recorded in the Survey Records.

3.5.7 Attention is to be given to all relevant statutoryrequirements of the Coastal State Authority in the area wherethe installation is to operate and/or the Authority in the

country in which the installation is registered.

3.5.8 When LR is to carry out verification on behalf of aNational Administration, classification surveys required by theRules, will, where practicable, be combined, and aligned, withthe surveys required by the National Administration.

3.5.9 All installations classed with LR are also to besubjected to Special Surveys in accordance with therequirements given in Chapter 3,5. These surveys becomedue at five-yearly intervals, the first one five years from thedate of build or date of Special Survey for Classification asrecorded on the ClassDirect Live website, and thereafter fiveyears from the date recorded for the previous Special Surveys,see also 3.2.11. Consideration may be given at the discretionof the Committee to any exceptional circumstances justifyingan extension of the hull classification to a maximum of threemonths beyond the fifth year. If an extension is agreed thenext period of hull classification will start from the date of theSpecial Survey before the extension was granted. A definitionof exceptional circumstances is given in 3.5.5.

3.5.10 Special surveys may be commenced at the fourthAnnual Survey after completion, commissioning, or previousSpecial Survey, and be progressed during the succeeding yearwith a view to completion by the due date of the SpecialSurvey.

3.5.11 Special Surveys which are commenced prior to theirdue date are not to extend over a period greater than 15 months, if such work is to be credited towards the SpecialSurvey. Where the Special Survey is completed more thanthree months before the due date, the new record of SpecialSurvey will be the final date of survey. In all other cases thedate recorded will be the fifth anniversary.

3.5.12 At the request of an Owner, the Committee mayagree that the Special Survey of the hull/structure is carriedout on the Continuous Survey basis, where all compartmentsof the hull are to be opened for survey and testing, inrotation, with an interval of five years between consecutiveexaminations of each part. In general, approximately onefifth of the Special Survey is to be completed each year andall the requirements of the particular Special Survey of thehull/structure must be completed by the end of the five yearcycle. If the examination during Continuous Survey revealsany defects, further parts are to be opened up and examinedas considered necessary by the Surveyor. For examination ofitems listed in Ch 3,2.2.13, 2.6 and Ch 3,3.2.3, 3.2.4, 3.2.6,3.2.8, 3.2.9 and 3.2.11 the intervals for inspection willrequire to be specially agreed. Units which have satisfactorilycompleted the cycle will have the date of completion enteredin the Survey Records which will not be later than five yearsfrom the last assigned date of complete Survey of thehull/structure. The agreement for surveys to be carried outon Continuous Survey basis may be withdrawn at thediscretion of the Committee.

3.5.13 The Owner is to prepare a planned surveyprogramme for the inspection of the hull/structure after eachSpecial Survey before the next Annual Survey is due. Thesurvey programme is to cover the requirements for AnnualSurveys, Intermediate Surveys, Special Periodical Surveys,Special Continuous Surveys, Docking Surveys and In-waterSurveys in lieu of Docking Surveys and is to be submitted to

LR for review. A copy is to be kept on board and madeavailable to the Surveyor. The programme should includeplans, etc., for identifying the areas to be surveyed, the extentof hull cleaning, locations for non-destructive examination(including NDE methods), nomenclature, and methods for therecording of any damage or deterioration found. Theplanned survey programme, as agreed by LR, will be subjectto revision if found to be necessary at subsequent surveys orwhen required by the Surveyor. See Ch 3,1.6.

3.5.14 The requirements for survey and the schedule ofsurveyable items may be amended when any variation inservice duties, usage or change in type notation areproposed, by agreement between the Owner and theCommittee.

3.5.15 Machinery is to be subjected to the surveys detailedin Chapter 3, Sections 6 to 12, see also Section 20.

3.5.16 Drilling/process plants, riser systems, safety andcommunication systems and hazardous areas are to besubjected to the surveys detailed in Chapter 3, Sections 13 to16.

3.5.17 Complete Surveys of machinery and drilling/process plants and riser systems become due at five yearlyintervals, the first one from the date of build or date of firstclassification as recorded on the ClassDirect Live website andthereafter five years from the date recorded in the Surveyrecords for the previous complete survey. Consideration canbe given at the discretion of the Committee to anyexceptional circumstances justifying an extension ofmachinery class to a maximum of three months beyond thefifth year. If an extension is agreed to, the next period ofmachinery class will start from the due date of CompleteSurvey of machinery before extension was granted. Surveyswhich are commenced prior to their due date are not toextend over a period greater than 12 months, except with theprior approval of the Committee. Where the complete surveyis completed more than three months before the due date,the new date recorded will be the final date of survey. In allother cases the date recorded will be the fifth anniversary.

3.5.18 Upon application by an Owner, the Committeemay agree to the extension of the survey requirements formain engines, which, by the nature of the units normalservice, do not attain the number of
