TECHNICAL REPORT

1 INTRODUCTION Ballast tanks are generally known to be susceptible to coating degradation and corrosion attacks. Relevant tests have therefore been developed for classification of ballast tank coatings. The coating system Jotacote Universal applied to sweep blasted zinc silicate shop primed substrate has been tested in accordance with the procedures for these tests.

An overview of the procedure is given in Appendix A.

2 SCOPE OF WORK The following work and tests have been performed: • Identification of the coating system • Film thickness measurements and pin hole detection on panels before testing • 180 days testing in condensation chamber • 180 days testing in wave tank • Evaluation of results after testing, including blister detection (when applicable), undercutting

from scribe, adhesion and coating flexibility • Evaluation of cathodic protection during testing (wave tank)

3 WORK CARRIED OUT PRIOR TO EXPOSURE

3.1 Identification The coating system was identified by infrared scanning (by means of a Perkin Elmer FTIR Spectrometer Paragon 1000), by determination of specific gravity (according to ISO 2811–1 /2/ by means of a Erichsen Mod. 290/1 Pyknometer) and by determination of volatile/non-volatile content (according to ISO 3251 /3/).

3.2 Application 3.2.1 Procedure Two coats (specified dry film thickness 150 µm per coat) of Jotacote Universal were applied to the sweep blasted zinc silicate shop primed panels.

The applicability was evaluated by visual examination with regard to application easiness and application pattern.

3.2.2 Coding The panels were coded as shown in Figure B-1, Appendix B.

3.3 Dry film thickness The dry film thickness measurements were carried out by means of an Elcometer 456 dry film thickness unit before testing.

TECHNICAL REPORT

3.4 Pin hole detection Pin hole detection was performed on the coated test panels before testing. The detection was carried out by means of an Elcometer 269 Pinhole detector at 90 volts.

4 EXPOSURE CONDITIONS The testing was carried out according to DNV procedure, Testing and classification of ballast tank coatings (revision 2, 2002) /1/. A summary of the procedure is given in Appendix A.

5 TESTS CARRIED OUT AFTER EXPOSURE Evaluation of blisters and rust, adhesion, undercutting from scribe and flexibility was carried out according to Appendix A, § 5.

6 TEST RESULTS The results of the product identification are given in Table 1.

The application data are given in Appendix B, while the results of the examination of the coated test panels schematically are given in Table 2 and more detailed in Appendix C. Pictures of the panels after exposure are enclosed as Appendix D.

7 CONCLUSION Based on the requirements given in the DNV procedure - Testing and classification of ballast tank coatings - revision 2, 2002 and the results from the testing, Jotacote Universal coating from Jotun A/S applied to zinc silicates shop primed substrate has been given the classification B1 in a classification system from B1 to B6, in which B1 is the superior grade.

TESTING OF BALLAST TANK COATINGS - OVERVIEW OF TEST PROCEDURE

1 TEST PANELS • Cold-rolled 3 mm thick steel, grit blasted to Sa 2,5, according to ISO 8501-1:1988 (Swedish

Standard SIS 055900). Painted on the reverse side. • Substrate alternatives:

1. No further treatment 2. Pre-rusted and steel wire brushed / high pressure washed

The panels are pre-rusted in a salt fog chamber. The panels correspond to Rust grade C in ISO 8501-1:1988 after pre-rusting. The panels are then high pressure washed (50-100 bar and 13 ltr freshwater/min) and steel wire brushed to St3 according to the above mentioned standard.

3. Pre-rusted and hydro jetted The panels are pre-rusted in a salt fog chamber. The panels correspond to Rust grade C in ISO 8501-1:1988 after pre-rusting. The panels are then hydro jetted at 2000 bar (30 000 p.s.i.) and quickly dried to avoid flash rust.

4. Moist The panels have a 300 µm WFT Coaltar epoxy applied in a width of approximately 60 mm in the middle of the test panels. The panels are pre-rusted in a salt fog chamber. The surface of the blast cleaned areas of the test panels correspond to Rust Grade C in ISO 8501-1 after pre-rusting. The panels are washed with fresh water at 100 bar. One blast cleaned and pre rusted area is washed only, while the other is wire brushed to St 2 according to ISO 8501-1:1988 (Swedish Standard SIS 055900) after washing. Immediately before application of the test coating the panels are first dipped in distilled water and then stippled with a wet and wrung cotton cloth

5. Shot blasted and shop primed A zinc shop primer with low zinc content is applied to a dry film thickness of 15 - 20 µm, measured on a plane steel panel according to ISO 2808:1991. The shop primed test panels are then exposed to outdoor marine atmosphere for 14 days. Prior to application of the test coating, the shop primed surface is washed with tap water and dried.

• Application of test coating according to the coating producer’s data sheets. • Curing at 18-24 °C and a relative humidity between 40 % and 60 % for 2 weeks before

exposure-testing.

2 TEST METHODS

2.1 Ballast wave tank test In accordance with the DNV procedure, Testing and Classification of Coatings.

Exposure cycles: 2 weeks in seawater with wave movements followed by 1 week with high relative humidity (some seawater left in the bottom of the tank) to a total exposure time as given in § 3.

3 EXPOSURE TIME BALLAST WAVE TANK TEST AND CONDENSATION CHAMBER TEST

• 180 days for coatings applied to blast cleaned panels and shop primed panels.

• 120 days for coatings applied to pre-rusted and hydro jetted panels. • 60 days for coatings applied to pre-rusted and then wire brushed panels and pre-rusted

and then wire brushed, moist panels.

4 PHYSICAL TESTING AFTER EXPOSURE • Flexibility testing.

• Adhesion testing.

5 EVALUATION AND CLASSIFICATION OF COATINGS The evaluation is based on visual examination of blistering, rusting and undercutting from scribe. In addition adhesion and flexibility are determined. The following standards are used:

• ISO 4628 - 1982, parts 1, 2 and 3 • ISO 4624 - 2002 • ASTM D522 – 2001, method B.

The classification is given in Tables 1 and 2. Table 1 Classification of Semi-Hard Coatings

Semi-Hard Coatings classification

Area rusted Area blistered

Class C1 Ri 0 to Ri 1 (0 - 0.05 %) on all panels. Density 0 - 1

Class C2 Ri 2 to Ri 3 (0.5 - 1 %) on top and side wave tank panels, other panels maximum Ri 2 (0.5 %)

Density 2 - 3

Class C3 Ri 3 to Ri 4 (1 - 8 %) on top and side wave tank panels, other panels maximum Ri 3 (1 %)

Density 3 - 4

Class C4 Ri 4 to Ri 5 (8 – 50 %) on top and side wave tank panels, other panels maximum Ri 4 (8 %)

Density 4 - 5

Class C5 Ri 5 (40/50 %) on all panels Density 5

Class C6 More than 50 % of area rusted on all panels Density 5

Note: If under-rusting is revealed, the classification will be affected accordingly.

The diameter of the mandrels used is 260 mm, 150 mm, 75 mm and 40 mm

Exposure time: 120 days (Total time 180 days. Each cycle consists of 2 weeks seawater immersion and 1 week exposure in air (See Appendix A))

Utilisation factor: 0.8

Consumption rate for Zn-anodes: 11.3 kg/A year 1) The cathodic disbondment is at present not used in the classification of the coating system. The parameter is being evaluated for inclusion in an upcoming revision 03, and is reported for future reference. 2) During 2002 (due to implementation of revision 02 of the test procedure, Appendix A) a holiday (8 mm diameter) was introduced to ballast tank coat panels with CP, as a part of the development of the test. This causes a higher current demand, as compared to previous measurements where no holiday was created in the coat.
