All surfaces shall be surveyed by Owner's, Builder's and paint manufacturer's surveyors before starting painting, between each paint coat and after finishing painting. The Owner's and paint manufacturer's representatives shall have the right to inspect and report on the standard of surface preparation and quality of coatings at all stages of application, and to request corrective measures should deviations from either the specification or good practice be discovered. The surface preparation and painting work of the sub-contracted machinery, equipment and piping shall be carried out in accordance with this specification and in agreement with and under control of the Builder. Halul Offshore Services Company L.L.C Page 39

40 Paint and coating guarantee A paint coating guarantee of 36months from delivery date on shall be given by the Builder for all painting works. Blisters, peeling off from substrate or between coats, loss of adhesion, cracking or flaking shall be considered as defects for all paint guarantees, even if they are not associated with visible corrosion. All paint guarantees shall include the supply of materials, surface preparation, paint application and all associated costs and expenses. Surface Preparation. General Abrasive blasting materials used for surface preparation shall be cleaned, hard angular, PH neutral, dry, paint manufacturer pre-approved, and shall have a chloride level of not more than 20 ppm and a conductivity of less than 100 µsiemens/cm (ASTM D49-40). Before application of any coatings, all surfaces to be coated shall be cleaned by applicable means from visible salts and other contamination such as but not limited to dust, moisture, fats, oils, soap solution, white deposits, soot from welding and cutting, chalk marks, marking paints and other foreign materials. Before pressure testing of tanks and compartments butt and seam welds shall be surface prepared and coated with shop primer for rust prevention. Any paint damage shall be made good at each coating stage before the application of further coats. Primary surface preparation All surfaces of steel plates and sections shall have mill scale and rust removed prior to use by means of shot/grit/quartz/sand/copper slag blasting to a bright metal (Sa 2.5) finish. After blasting plates shall be primer coated immediately with one coat of 20 microns shop primer. During fabrication the primer coat shall be touched up where damaged by mechanical means or by welding. The surface preparation work of the subcontracted machinery, equipment and piping shall be carried out in accordance with this specification and in agreement with and under control of the Builder. Secondary surface preparation Before the first paint coat is applied in ballast, freshwater, foam and detergent tanks, all sharp edges must be ground smooth with 3C edge preparation. In other areas 1C edge preparation shall be applied for all sharp edges. Burr caused by gas cutting shall be removed from all cut edges of structural members. Welding slag and spatter clinging to surfaces on and around welding beads shall be removed by hand scraper and/or disc sander. Sharp peaks shall be ground flush. Gas-burnt areas and other damaged parts of shop primer and weld seams shall be shot-blasted or mechanically cleaned to SIS St 2 or 3 and touched-up with zinc epoxy shop primer for rust prevention. When the extent of the rusted or damaged portion of a plate caused by welding, burning, etc. exceeds 40% of the plate area or if the Shop primer is broken down more than 50 % or Shop primer prescribed protection duration (as per Paint Data Sheet) is exceeded, sweep-blasting should be used for the surface preparation. Furthermore, it should be understood that when shop-primed surfaces are corroded to such an extent that they cannot be adequately made rust free by sweep-blasting, full re-blasting shall be applied. Furthermore, if areas are poorly prepared or not painted to an acceptable standard of finish, the specified over coating is interval exceeded or the adhesion of subsequent coats is jeopardized, then re-blasting in parts or in whole shall be performed. In normal circumstances, secondary surface preparation grades shall be applied as follows: Area: Preparation Grade: Halul Offshore Services Company L.L.C Page 40

41 Shell bottom and topside SA 2.0 Weather decks SA 2.0 Deckhouse exterior St 2 Deckhouse and ER interior St 2 Ballast, fresh water detergent and foam St 3 / SA 2.0 tanks Lube oil, bilge, dirty oil tanks St 2 Fuel oil tanks St 1 Others St 2 For this surface preparation grit/ sand blasting or power tooling by disc grinder shall generally be applied. The use of powered wire brushes shall be minimised. Before over coating all surfaces shall be cleaned of oil, moisture, dust and other foreign materials with thinner, freshwater, wire brush, or compressed. 336 Paint Application. Conditions for paint application No painting shall be carried out under adverse weather conditions such as rain, fog, snow or under freezing conditions. The dew point of air shall be at least 3 C below the steel surface temperature and the relative humidity shall not exceed 85% during paint application. Air humidity shall be controlled during application and shall be within the accepted limits of the applied paints. The manufacturers application recommendations shall be obtained. No paint application shall take place if the chloride contamination level exceeds 3µg/cm 2. Application methods Painting work shall be performed by airless spray as far as possible. Roller and brush shall be used only for touch-ups, minor repairs and markings. All tanks and in weather exposed areas one (1) stripe coat shall be applied prior to each full coat. The stripe coating shall be applied to all weld seams, edges, corners, rear ends of bulbs, fittings, and other locations not accessible or suitable for spray gun application. Stripe coatings shall be applied by brush. All steel structure areas where components are attached by screws and bolts shall be stripe coated before the components are fitted. During dry-docking before sea trials the underwater shell shall be high pressure water washed and fresh water cleaned before the application of the last anti-fouling coat. Salt measurement shall be performed before paint application. All defects shall be repaired before the application of the final anti-fouling coat. The water used for cleaning shall be clean, contamination free and have a conductivity of less than 300 µs/cm. Coating Quality Criteria. Painted visible surfaces shall be free of sags and runs. The dry film thickness shall be measured after each coat to confirm adequate thickness. The underwater hull paint thickness shall be checked and recorded before and after the application of anti-fouling paint. No limitation shall be made on the location and number of points for paint thickness measurements. The dry film thickness (DFT) of the paint coats shall be measured by digital equipment. In ballast, freshwater, foam and detergent tanks 100% of the specified DFT shall be achieved at a minimum of 90% of the measured points, at the remaining 10% of the measured points at least 90% of the specified DFT shall be achieved (90/10 acceptance criteria).
