RECORD : 03 TEST METHOD : IDENTIFICATION OF FABRICATION DEFECTS STANDARD : ISO 8501-3 PURPOSE Coatings tend to draw thin and pull away from sharp edges and projections, leaving little or no coating to protect the underlying steel, thereby increasing the potential for coating failure. Other features which are difficult to properly cover and protect include crevices, weld porosity, skip weld and laminations. Thus, identifying surface defects would help to determine the necessary actions needed to be taken prior to abrasive blasting. APPARATUS VISUAL EXAMINATION PROCEDURE 1. Examine the surface defects prior to surface preparation. Identifying all the potential factors such as sharp edge, corner, weld porosity, weld smoke, weld spatter, skip weld and lamination that tends to create premature coating failure 2. Mark location of any surface imperfection and defects on the test panel as it will be easily identified for further treatment or action. FINDING AND ACCEPTANCE/REJECTION Sharp edge, rough weld, and weld smoke Norsok M501 Acceptance Criteria: Sharp edge must be ground smooth to at least 2.0 mm Rough weld must be ground smooth to remove any sharp protrusion Weld smoke must be cleaned properly to avoid coating adhesion failure CONCLUSION Test panel needs further treatment for SSPC-SP1 Solvent Cleaning and SSPC-SP2/SP3 Hand-/Power-Tools Cleaning prior to abrasive blasting.

RECORD : 13 TEST METHOD : MIXING AND AGITATING OF THE TWO-COMPONENT EPOXY STANDARD : SSPC-PA1 PURPOSE This procedure describes the proper mixing of part A and B in order to verify that the proper coating components and ratio are mixed accordingly. APPARATUS PNEUMATIC AGITATOR PROCEDURE When mixing multi-component coatings, it is important that materials are mixed in the correct ratio. Manufacturer's instructions should be followed with respect to induction period of pot-life requirements. Two-component coating must be mixed in the correct proportions and in the manner specified by the supplier to achieve optimum film properties. They are normally mixed as follows: 1. Stir the base component (Package A) with a clean paddle to disperse pigment lumps that may have settled (five minutes is usually adequate). 2. While continuing to stir, slowly add all of Package B (sometimes called the catalyst, co reactant, or curing agent), which is frequently unpigmented (the mixing container must be large enough to hold both components). 3. Agitate the two mixed components with a power stirrer until a smooth consistency is achieved. 4. Any mixed material remaining after the job is completed should be properly disposed. FINDING AND ACCEPTANCE/REJECTION Part A & B is mixed accurately in an appropriate manner as per mixing ratio stated in product technical data sheet. Norsok M501 Acceptance Criteria: Mixing, mix ratio, thinning, working pot life, drying and curing time, coating interval time, and method of application should be in accordance with the material’s technical data CONCLUSION Complied to Norsok M501 requirement

Stripe coating of edges, corners, rivets, welds, etc., is advantageous in preventing breakdown of coating on such edges in very corrosive surroundings. APPARATUS BRUSH PROCEDURE 1. All corners, crevices, welds, and sharp edges shall be stripe coated with the priming coating before the steel receives its first full prime coat of coating. 2. Such striping shall extend a minimum of one inch (2 cm) from the edge. The stripe coat shall set to touch before the full prime coat is applied. 3. The stripe coat shall not be permitted to dry for a period long enough to allow rusting of the unprimed steel. FINDING AND ACCEPTANCE/REJECTION Stripe coating is done in an appropriate manner to all welds, corners, behind angles, edges and areas that are not fully reachable by spray. Norsok M501 Acceptance Criteria: For each coat, a stripe coat shall be applied by brush to all welds, corners, behind angles, edges of beams etc. and areas not fully reachable by spray in order to obtain the specified coverage and thickness.

COATING MATERIALS

Manufacturer’s technical data sheet (see Interzone 954, page 3 of 4, product characteristics): For use in atmospheric service, a minimum dry film thickness of 350 microns is required in one coat when applied direct to steel. For water immersion, a minimum of 450 microns dry film thickness is recommended, however, Interzone 954 can also be used as a non-skid deck system, typical thickness will be between 500 – 1000 microns. Other information: Type of spray equipment used : Hasco 63:1 Tip size : 319 Input pressure to airless pump : 70 psi Atomizing pressure : 4410 psi % Thinner added : no thinning CONCLUSION No single spot measurement less than 80% of the specified thickness. Even some spot measurements observed for the 2nd coat are greater than 120% of the specified thickness, however, this kind of material, Interzone 954, can be applied up to 1000 microns. Thus, the thickness of test panel still satisfies to the requirements of Norsok M501.

RECORD : 18 TEST METHOD : HOLIDAY (DISCONTINUITY) STANDARD : NACE RP0188 PURPOSE Newly coated structures on which the coating integrity is important (particularly linings or coatings in immersion conditions) should be tested with a holiday detector to ensure coating film continuity. A holiday (sometimes called discontinuity) is a pinhole or other break in the film that permits the passage of moisture to the substrate. This allows substrate deterioration to begin. Holidays are not easily detected visually, and must be located with electrical instruments called holiday detector. APPARATUS ELCOMETER 236 DC HOLIDAY DETECTOR PROCEDURE 1. Place the probe on the test surface. Keep the probe in contact with the surface and move it over the work area at a speed of approximately one meter every four seconds, 0.25 m/s (10"/s). 2. The presence of one or more of the following indicates that there is a flaw in the coating: • A spark between the probe and the surface • ALARM flashes • The audible alarm sounds • The output voltage, indicated on the LCD display, drops substantially • The probe neon indicator glows 3. The probe should always touch the surface. Gaps between the probe and the coating can result in genuine flaws not being detected. FINDING AND ACCEPTANCE/REJECTION CPT test panel is totally free from holiday (negative) at 2.5 kV. (Note: for a coating thickness of 500 µm, NACE RP0188 recommended to use 2.5 kV or 2500 V, see following table, depicted in aforementioned standard page 04).

RECORD : 19 TEST METHOD : PULL-OFF ADHESION STANDARD : ISO 4624 / ASTM D4541 PURPOSE To measure the bond strength of applied coatings since adhesion is the key requirement in a corrosion resistant coating. Irrespective of most of its other properties, the coating with strong adhesion to the surface will retain its integrity much longer than the one with less adhesion with other strong characteristics. APPARATUS ELCOMETER 106 ADHESION TESTER ARALDITE GLUE PER STANDARD SPECIFICATION PROCEDURE 1. The surface of the dolly and the test area should be abraded and be free from oil, moisture and dust to ensure a good bond between the dolly face and the coating. 2. Prepare the surface of the dolly and the coating where the dolly is to be applied by roughening with an abrasive paper. Then de-grease these areas by using a suitable solvent to clean both surfaces. 3. Mix a small quantity of adhesive and apply an even film to the prepared surface of the dolly. Place the dolly onto the prepared test surface and apply pressure to squeeze out excess adhesive which should then be removed. Allow the adhesive to cure for the recommended time 4. After adhesive cures for a certain agreed period, cut around the base of the dolly very carefully using the dolly cutter. This is only necessary when lateral bonding in the coating is greater than adhesion, for example, elastomeric coatings. 5. Place the base support ring over the dolly ensuring that it lies flat on the surface. Slacken the handwheel or nut on the Adhesion Tester. Set the dragging indicator to zero (0) on the scale and engage the claw carefully with the dolly. 6. Hold the Adhesion Tester steady with one hand to prevent rotation and tighten the handwheel or nut slowly and evenly to apply an increasing force to the dolly and hence to the coating. 7. Continue until the coating fails and the dolly is removed from the surface, or until the specified test force is indicated. The pull-off force is read from the position of the dragging indicator after the test is complete. 8. Immediately after the test is complete and the pull-off force has been recorded, slacken the handwheel or nut to remove all the force from the unit. 9. To record the result, first inspect the face of the dolly. In most cases the coating will fully adhere to the dolly and the test can be claimed as 100% valid. In some cases, the coating will cover only part of the area of the dolly and a partial adhesion failure should be recorded. 10. If no coating is present on the dolly this must be recorded as a failure of the adhesive (or glue). This is normally due to incorrect or insufficient mixing of the component parts of the adhesive, or incompatibility of the adhesive and the coating. 11. Observing the test area will give additional information about the type of failure; adhesion and cohesion between different layers of the coating.
