HEMPEL

2.0 INTRODUCTION

The objective of the following Standard is to outline the information that is required for the supervision of aballast tank coating job. There are stages common to all tank coating jobs at which certain inspectionprocedures must be carried out.

The Standard is intended for guidance purposes and may be supplemented by experience. Slight deviationsfrom this Standard will be necessary depending on the actual Specification (local adjustments). However, itmust be understood that deviations should be for the benefit of the coating system involved, and any suchdeviations must be included in the individual working specification.

For HEMPEL's Coating Advisers on site the contents of this Standard will furthermore be supplemented byHEMPEL's Coating Adviser's Handbook/HEMPEL'S Coating Reference Handbook, which is more detailed insome respects plus Hempel's Photo Reference for Steel Surfaces Cleaned by Jetting.

Note:

1) Unless otherwise agreed, the Subcontractor/Shipyard must perform its own qualityassurance/quality control (QA/QC) service, including adequate reporting. HEMPEL's Coating Advisershould not be called for inspection until after Subcontractor's/Shipyard's inspection service hasapproved the surface in question. Attendance of HEMPEL's representative(s) does not relieve thesubcontractor/the shipyard from his/their responsibilities.

2) The Subcontractor/Shipyard has the full responsibility of observing all ruling safety regulations for allwork done by Subcontractor's/Shipyard's employees.

2.1 SHOPPRIMING AND STEEL WORK

2.1.1 Before starting the job

At large job, especially full refurbishments, a pre-job conference with all relevant parties should take placedetailing the inspection job to follow (see also Section 1.0.2 in HEMPEL's Technical Standard for BallastTank Coating Work).

2.1.2 Shoppriming

In case of newbuildings/new steel, special guidelines for control of shoppriming have to be followed. (Pleasesee the "Shopprimer Handbook", Inspection Report and Checklist for Shopprimer Lines).

2.1.3 Steelwork and steel surface condition

All steelwork, whether in raw steel condition or in shopprimed condition, must be checked for the followingdepending on ballast tank coating systems types I, II or III specified (furthermore, see Section 1.1.1, Part 1).

a. Weld spatter (for system type III to be removed by grinding, discing or chipping. Loose spatters to beremoved in any case).

b. Plate laminations removed by grinding (or re-welded if necessary).

c. Sharply profiled weld undercuts repaired or marked for extra stripe coating.

Part 2




HEMPEL

d. Rough hand welds or any rough machine welds to be ground to produce a smoothly contouredsurface or marked for extra stripe coating.

e. Sharp edges broken or rounded (system types II & III). Protruding sharp edges/burrs to bechamfered (system type I).

f. Welding lugs and brackets removed and ground smooth. The same applies for lifting pieces if theseare not permanently installed.

g. Porosities of welds to be remedied/marked for filling.

h. Welding smoke: Fresh welds to be controlled for alkaline deposits. A pH-paper is soaked withdistilled and pressed to the surface for 30 seconds. If pH is 9 or higher, it is recommended to washthe surface. Check at a distance of 2-8 cm or more from the welding seam. Especially undersideabove a weld may be contaminated by smoke. Besides pH check, the Bresle Method may be used -please see next page.

j. Absence of oil and grease is controlled by visual means, possibly combined with the " on goose"test or the "chalk mark test" - see the Coating Reference Handbook.

The following additional method may be employed for detecting of any oil or grease:

Hydrocarbon test with isopropanol:

1 m² of the surface is washed with cotton-wool and hydrocarbon free isopropanol.After each washing the isopronanol is transferred from the cotton-wool into a beaker bypressing.Filtrate the contents of the beaker.Mix in a test tube the filtrate with 2-3 times as much distilled water.The mixture is shaken and must be allowed to stand for approx. 20 minutes.If the sample in the test tube is cloudy, the surface is contaminated with grease and/or oil.Make a blank mixture of the isopropanol with distilled water as reference. Instead of isopropanol a hydrocarbon free acetone may be used.

k. Soluble salts:

If steel is suspected of being contaminated with chlorides or other water soluble substances awashing test is performed according to the following procedure:

i) Select random test areas. Especially areas where white-rusted zinc shopprimer or blackdeposits after plasma cutting bath are observed should be selected.

ii) Test the selected areas by the BRESLE METHOD. Reference is made to the CoatingReference Handbook.

The shipyard has the full responsibility of executing and checking the steel work.

2.2 EQUIPMENT AND CONDITIONS

2.2.1 Staging/scaffolding and accessibility

An integral part of most tank coating work is the staging or scaffolding. Certain basic requirements shouldbe checked - the shipyard/contractor has the responsibility of fulfilling the safety requirements.

2.2.1.1 Check that all contact between the steel and tubular scaffolding is point contact only, i.e. spadeends should be fitted.

2.2.1.2 All steelwork is to be accessible for blasting and painting operations, i.e. staging boards mustnot prevent access for abrasive blasting, cleaning, and subsequent paint application.

2.2.1.3 Corrugated bulkheads must be staged to give adequate access to recessed areas so thatsurface preparation, paint application, and inspection can be carried out safely.

2.2.1.4 All tubular staging poles to be plugged or capped to prevent ingress of blasting medium.

2.2.1.5 All staging must be capable of being cleaned satisfactorily.

Furthermore, see Section 1.1.2 of Part 1.

2.2.2 Lighting

General lighting is considered sufficient if it allows the reading of a text like the present at a distance of 30cm/1 ft.

2.2.3 Ventilation, dehumidification and steel temperature

An important part of any tank coating work is the air conditioning and the steel temperature inside thetanks.

The air condition in a tank can be altered quite effectively and quickly by using ventilation anddehumidification equipment. A change in steel temperature, however, can take days and with vessels in thewater it cannot usually be done at all for the area which is immersed. Therefore, to obtain a quick change inconditions either the volume of dry air going into a tank is increased or the water content of the samevolume of incoming air is decreased (may be of relevance during the abrasive blasting or during cleaningbefore painting).

In the general case it is important to have dry, condensation free conditions before and during paintapplication - as well as sufficient humidity after application of ethyl zinc silicate - and check on theconditions in the tank or tanks should be made at every opportunity, certainly every time there is aninspection. As a minimum the conditions in the tank must be checked 2-3 times per 24 hours, earlymorning, noon and evening/night during the surface preparation, 1-2 times per 24 hours during drying andcuring. No condensation must be allowed on painted surfaces between coats or until the coating system hasdried/cured sufficiently to resist humidity.

To avoid re-rusting before paint application relative humidities should be as described in Part 1, Section1.1.4.

Part 2




HEMPEL

Condensation will occur on surfaces with temperatures below the dew point of the air adjacent to thatsurface. At steel temperatures below the dew point the air is saturated with water vapour and condensationconsequently occurs. To avoid condensation during/after painting the steel temperature should bemaintained at least 3°C above the dew point of the air in the tank and the relative humidity must be kept aslow as possible, below 50% and preferably at approx 40%. The lower the relative humidity, the lower the riskof condensation.

Steel temperature has a very marked effect on drying times and the curing rate of tank coatings.

During drying the tanks must be ventilated with an adequate supply of clean air to assist removal of solventvapours from the tank coating and the tank. (In case of water-based zinc silicates, special measures are tobe taken, reference is made to the Application Instructions for HEMPEL'S GALVOSIL 15620).

2.3 SURFACE PREPARATION

2.3.1 Abrasive blast cleaning/blast sweeping

In all paint systems the performance is dependant on the quality and type of surface preparation. If thesurface preparation is below specification, a reduction in service life can usually be expected.

2.3.1.1 Before the Subcontractor commences abrasive blasting, the Coating Adviser and the contractormust agree on the standard of blasting and any surface profile required.

2.3.1.2 Each delivery of abrasive material must be checked for conformity in accordance with Hempel'sinstructions Coating Reference Handbook.

2.3.1.3 Immediately before blasting the ambient conditions in the tank should be checked. Conditionsshould be such that the steel temperature is 3°C above the dew point of the air in the tank andthe relative humidity should be below 50%, preferably around 40% (see Section 1.1.4). Thesereadings are to be checked above and below the waterline, where applicable, and at the top,centre and bottom of the tank.

With all tank coating work a minimum steel temperature for application and curing of paint willapply. If at the commencement of blasting the steel temperature is below that minimum, thenthe Subcontractor/Shipyard must be informed that although conditions are suitable forabrasive blasting they may not be suitable for painting.

Ambient conditions should also be rechecked at the completion of the blasting shift and ifpossible at the mid-shift break. All readings to be logged and any necessary recommendationsmust be made to the Subcontractor/Shipyard in writing.

Existing equipment that allows continuous monitoring of thermometers and hygrometers storingmeasured values on graphs or by other means may be used.

2.3.1.4 At the completion of the abrasive blasting, a rough cleaning operation is normally done, afterwhich the surface is inspected. The following checks and tests should be carried out and theresults recorded accordingly.

Note: Because of insufficient rough cleaning, abrasives and especially dust may be hideinsufficiently blast-cleaned areas of the tank. Such places will then show up after final cleaning.

Part 2




HEMPEL

2.3.1.4.1 Visual AppearanceTo comply with the visual standard designated in the specification. A small mirroris normally used for checking areas not accessible for direct visual observation.

2.3.1.4.2 Surface Profile Measurements, if relevantTo be randomly spot-checked. This is done most conveniently together with thespot-checking of the visual appearance, however, a minimum of 5 spot-checkswith the Comparator should be done per tank or per area in question.

2.3.1.4.3 Soluble salts: detection of such will mostly be relevant for repair work. Mustfollow the rules as described above under Section 2.1.3, k.

If salt contamination occurs and the steel surface is pit-corroded, the onlyeffective remedy is fresh water washing followed by a new abrasive blasting! -alternatively water jetting. If the steel is free from pits, experience shows thatrepeated dry abrasive blasting can remove salts.

If points 2.3.1.4.1, 2.3.1.4.2 and 2.3.1.4.3 are up to standard, final cleaning of the blastedarea may be carried out.

2.3.1.5 During the inspection after final cleaning of the tank the degree of cleaning of the steel surfacemust be according to the specification.

Furthermore, it must be checked that all abrasives and dust have been removed from the steelsurface. All staging boards must be clean and free from dust, and all staging pipes must besimilarly cleaned. The steel surface must finally be vacuum-cleaned free from dust. A tape-testfor control of de-dusting may be used in accordance with ISO 8502-3:1991.

2.3.1.6 Checks of ambient climate must be done at the following points of time during the abrasiveblasting and cleaning operations.

1. Immediately before abrasive blasting

2. During the mid-shift break if possible

3. At the inspection after the rough cleaning

4. At the completion of the final cleaning inspection.

2-3 hours before this inspection the power of ventilation should be brought to the samelevel as would be maintained during the painting and drying period.

The condition should be checked at the top, centre and bottom of the tank and at anyareas where the steelwork may be colder than the rest of the tank due to influence fromoutside, e.g. above and below waterline.

Part 2




HEMPEL

The following readings should be taken:dry bulb temperature }wet bulb temperature } alternatively a calibrated capacitative RH-meter relative humidity } may be used.steel temperature }

Dew point temperature to be calculated.

If any areas are approaching the dew point or the relative humidity is approaching 50%,the contractor/shipyard should be informed to ensure that the conditions are improved.After acceptance of abrasive blasting and cleaning, painting should begin as soon aspossible. If painting does not commence within 4 hours of the final cleaning inspection,recheck the tank conditions.

2.3.2 Water Jetting

Relevant primarily for big repair jobs/full refurbishment. Many of the inspection routines described above(2.1.3 to 2.3.1) will also apply to the job of controlling water jetting.

The most relevant grades of cleaning, visually and non-visually controlled as per the joint standard (NACENo. 5/SSPC-SP12 - mentioned in chapter 1.2.7) - will be:

WJ-2: Ultra high pressure water jet cleaning to a uniform matte finish with at least 95% of the surface areabeing free of all previously existing visible residues, and the remaining 5% containing only randomlydispersed stains of rust, coatings, and foreign matter.

SC-2: A SC-2 surface has less than 7 µg/cm² chloride contaminants, less than 10 µg/cm² of solubleferrous ion levels, and/or less than 17 µg/cm² sulfate contaminants as verified by field or laboratoryanalysis using reliable, reproducible test equipment.

It is noted that HEMPEL consider the contamination with soluble salts in general and our acceptancelevel covers the "worst case", chloride contamination as detected by the "Bresle Method".

After finalizing the water jetting, it is very important that no dry "sludge" as well as no loose powdery rust isto be found on the surface. An acceptable degree of new rust is FR-2 according to Hempel's PhotoReference for Steel Surfaces Cleaned by Water Jetting.

The best way to remove dry sludge is a high pressure hot water (steam) cleaning shortly after ultra jetting - ifnecessary. The "steam cleaning" will also remove powdery new rust and leave a rather warm surfaceassisting drying out.

If the surface appears with new powdery rust, but free of other contaminants, a light brushing with steel wirebrushes may solve the problem.

2.4 APPLICATION

2.4.1 Storage of Paints

Check that the correct type and quantity of paint has been delivered on site and that it is adequately storedor protected under cover away from possible water contamination and from extremes of temperature. Ifnecessary, the paint must be conditioned before taken into use.

2.4.2 Paint Application

Before application of any paint the Coating Adviser must in principle check the following:

2.4.2.1 That the Shipyard/Subcontractor has suitable application equipment including a full range ofspray tips for the coating system to be used. He must also check that the sprayer has a wetfilm gauge for checking wet film thickness during application.

2.4.2.2 That Shipyard/Subcontractor has dehumidified air, ventilation and heating equipment tomaintain the steel in a dry condition at a temperature above the specified minimum at all timesduring the paint application and subsequent curing.

2.4.2.3 That the area for mixing the paint and set up of spray pumps/pots has adequate cover (amodified 20' container can be suitable).

That all paints are mixed satisfactorily in accordance with the mixing procedure for the paint inquestion. Mixing of components should be done with a low-speed mechanical mixer.

2.4.2.4 That all paints are stored/conditioned at a temperature above approx 15°C, below 30°C priorto painting.

2.4.2.5 If more than 4 hours have elapsed since the tank was accepted for painting, it must bechecked that the tank conditions are such that the steel surface is still in suitable condition forpainting.

2.4.2.6 The amount of paint to be used in the tank should be calculated based on practical coveragesand the tank area. At random stages during the paint application, the Coating Adviser shouldvisit the spray set-up and check that the paint is being mixed and used correctly and at thecorrect temperature. At the completion of the spraying operation the amount of paint actuallyused per tank must be recorded.

After the drying, but before curing of the paint, the Coating Adviser must inspect all areas inthe tanks, taking special care to inspect areas that are not readily accessible for spraying, e.g.plate edges, backs of bars, scallops, cut outs and welds etc. He must check that:

a. The whole surface has been covered.

b. The paint film is of the correct colour, gloss and appearance indicating that it has beenmixed and applied correctly.

c. The dry film thickness is within the specified limits and free of visible porosities orimproper film formation for each coat.

Part 2




HEMPEL

It is especially important that the first coat is applied to secure full film formation leading tooptimum wetting and thereby adhesion to the substrate.

Note wellFilm thicknesses below the specified limits will not protect adequately and should be broughtup to the specification standard. Similarly, film thicknesses in great excess of the specifiedlimits can be detrimental to the service life of the coating. Areas with film thicknesses in greatexcess of the limits laid down in the specification are subject to an exception form. It isabsolutely essential that the Shipyard, the Subcontractor and the Owners' representative aremade fully aware of this and that the film should be within the stipulated, correct dry filmthickness limitations.

In normal cases, it will be necessary to carry out a stripe coating operation before and/or afterthe spray coat on such areas as welds, edges of cut outs, edges of scallops, plate edges andbacks of bars. This stripe coating is done to ensure that the specified thickness of paint withinthe practical limits is achieved on areas that are difficult to spray coat satisfactorily. TheCoating Adviser must check that the stripe coating is done and areas designated for stripe coatare covered 100%. All stripe coating is preferably to be done by brush. However, stripe coatingby spray with small, narrow angled nozzles may replace brush application - except for cut outsand irregularities in welds such as deep undercuts and holes.

Depending on the surface condition of the steel work, type of free edges, quality of welds(undercuts, welding pearls, etc. included) more than one stripe coat will be relevant.

During the coating procedure the following must be controlled:

(i) That the ventilation and/or air-conditioning equipment is kept running during the wholepaint application programme and for a specified period after completion to maintain theconditions necessary to obtain proper film formation and curing. In this respect theconditions must be documented in the tanks 1-2 times per 24 hours.

(ii) That anyone entering a tank which is in the process of being coated must wear clean softsoled shoes to prevent scoring or scuffing or contamination of the blast cleaned/coatedsurfaces.

(iii) That Shipyard/Subcontractor keeps the deck free from blasting material and debris in thevicinity of tanks being painted.

(iv) That openings for tank cleaning machines are adequately covered to prevent ingress ofdirt or water.

(v) That rain shelters are built over tank accesses.

2.5 FINAL ACCEPTANCE

2.5.1 Visual appearance

The paint film must be free from holidays, excessive runs (sags), contaminants or other visible defects .

Dirt, paint flakes (for instance from hoses) and similar must be removed by light scraping - or sanding - andfollowed by proper touch up. Special attention must be given to the lower parts of the tank as concerns thispoint.

In certain cases, sagging may be so "uniform" that no defects are seen on the vertical surfaces whereas a"pool" of paint is found on the horizontal part beneath the area. Such "pools" of paint must always beremoved. Make it a routine to spot-check for these kinds of possible defects too.

Generally all sags not ending on a horizontal surface may be left as removal often creates more damagethan is made good by touch-up afterwards.

If cracks in the paint film are found, these are to be spot-repaired.

All visible mechanical damage of the paint film must be repaired.

Anodes must NOT be painted and anodes are to have very tight contact to the steel. If bolted keep thebolting zone free of paint by taping off.

2.5.2 Measurements of dry film thickness

For measuring of dry film thickness, electronic gauges of a good quality must be used.

Calibration of gauges must take place within the thickness region which is to be controlled. Smooth steelpanels (thicker than 2 mm) are used as substrate for the calibration.

For the final control of the total dry film thickness of the system the following should be observed:

In principle, each measurement should consist of three (3) gauge readings. The three (3) gauge readingshave to be taken within a continuous area of 50 cm². Discard any unusually high or low gauge reading whichcannot be repeated consistently. Take the average of the three gauge readings as the "spot measurement".However, in practice it is impossible (with available equipment) to do so. Instead, single gauge readings areused as the "spot measurement".

Number of spot measurements will depend on the size of the unit.

1. Divide the control area into the following main categories:

a) Open surfaces, smallest dimensions >150 mm.b) Narrow surfaces, smallest dimensions <150 mm.

Each category to be controlled and approved separately in accordance with the 80-20 rule.

2. Based on ms or running m, respectively, the number of "spot-measurements" is seen from thefollowing table.

Part 2




HEMPEL

The sampling should be carried out at random.

Sub-categories of the tank surfaces will be:

- bulkheads } with or- deck } without- bottom } stiffeners- web frames- longitudinals, upper sides- longitudinals, under sides- bottom frames (if made with facebars, remember undersides of these)- brackets, knees and other small stiffeners

Using the above described rule for number of spot measurements plus dividing the tank into thementioned "sub-categories" of elements will give full statistical basis for safe acceptance orrejection of the film thicknesses applied.

In practise, localized areas with too low (or too high) thicknesses will be marked for repair.

Use of dry film gauges is described in ISO 2178, ISO 2808 and in SSPC-PA 2.

2.5.3 Control for adhesive/cohesive properties

The applied paint film is furthermore controlled spotwise for intercoat adhesion, adhesion to the substrateand as well as cohesive forces within the coating.

Being a destructive test it is done a few places only, mostly to check that no negative "external" factorshave influenced the performance:

- Sudden drops in temperature may create separation of components giving a slippery surface layer.

- Conditions of poor ventilation may have the same effect (often worsened if combined with lowtemperatures).

Part 2




HEMPEL

- Condensation may have occurred on a paint film not yet able to resist water completely.

The test is to be made in a few places per tank/per ballast tank section only.

Select places where the most unfavourable conditions of application (temperature, ventilation, filmthicknesses) are judged to have taken place.

If possible, go for areas near to places which will need later spot-repair in any case. Otherwise, it will be thesole duty of the coating adviser to repair the spots when carrying out control.

Preferably, the method should be the pull-off method by pneumatic equipment (according to ISO 4624) orsimilar equipment giving the most reproducible results.

Results to be included in the ballast tank coating report.

The pull-off testing can be supplemented with simple testing by cutting with a knife. A fast and goodqualitative method in the hands of an experienced coating adviser, but checked spots will still need repair.

2.5.4 Control for bare spots/holidays and for mechanical damage

The normal procedure for checking for bare spots/pinholes is through filling the tank(s) completely withfresh, natural sea water. The sea water should be left in the tank(s) for a minimum of 24 hrs. before thetank(s) is/are drained. If water filling is impossible, very thorough wash down is to be used instead. Closethe tank for a period of minimum 3 days. All internal areas are then to be checked for bare spots/pinholesand if such are found, repairs must be carried out after proper wash with fresh water.

Control for bare spots will typically be for System Type III, in certain cases Type II as well.

2.6 REMOVAL OF STAGING OR SCAFFOLDING

Normally staging is removed after the upper areas have been painted according to the specification andaccepted by all parties concerned. On no account must staging be removed until the tank has passed thecontrol. During the removal of staging it is inevitable that damage will occur. Destaging damage is alwaysdifficult to see from the tank bottom. Consequently, a systematic repair and touch up should be carried outduring dismantling of stagings. Start from the upper part and finish repair - note especially the fittings -before the next level of stagings is removed.

Mechanical damage/bare spots observed after dismantling of stagings should whenever possible berepaired using aluminium ladders or a bosun's chair as a mean of access.

2.7 REPORTING AND DOCUMENTATION

All stages of the tank coating work must be logged and systematically recorded. It is essential that allinformation relating to the work is passed on to all relevant parties as soon as possible.

For the purpose of documentation inspection forms and painting logs must be completed with the requesteddata.

Part 2




HEMPEL

It is important that the information requested on possible Daily Report Forms (major repairs) is given as wellas general progress reports on the job. Any problem encountered during the day should also be recorded; forexample paint problems or complaints, ventilation or dehumidification problems.

Exception Reports

An Exception Report Form must be issued for any deviation from the specification which is not suitablyrectified. Subcontractor, Shipyard and Owners representatives must be notified of any deviation from theSpecification. The method of rectification must be established by all parties concerned and approved ordisapproved by HEMPEL. If rectification is approved by HEMPEL, an Excemption Form remains issued, but itmust be stated on it that the rectification was approved by HEMPEL. If the rectification is not approved byHEMPEL, and work still goes ahead, an Excemption Form must be issued which states the reason whysuitable HEMPEL rectification was not carried out. Excemption Forms are to be signed by representatives ofall parties and copies retained by each party.
