The vendor coated items shall be assessed of its suitability for exposure against offshore or marine environment. Where vendor applied coating needs upgrading, the Company shall be notified for disposition of the suitable coating products/coating system to be applied on vendor applied coatings.Damages to vendor coated items shall be repaired in compliance with the Companysrequirements.PACKING AND STORAGEAll paint and coating materials shall be furnished in the manufacturer's unopened containers, which shall be identifiable and protected. Batch number and date of manufacture shall be clearly marked on the containers. The recommended shelf life and the "use by date" shall be clearly identified.All materials shall be stored out of direct sunlight in well ventilated areas and away from heat sources, In addition manufacturer's recommendation guideline in storage of coating materials shall be attached to.VISUAL CHECKINGPrior to paint work, the paint shall be visually checked confirming that the paint is in suitable condition for application. MIXINGAll components shall be thoroughly mixed by mechanical means. This mixing shall be done in clean containers, free from traces of grease, other paint or contaminants. Multi-component coatings, such as inorganic zinc, epoxy and polyurethane shall have the components accurately measured under the manufacturer direction. THINNINGThinning ratio of the materials will conform to the limits recommended by the manufacturer. Only manufacturer's specified thinner shall be used. POT LIFEThe coating manufacturer's recommended pot life shall not be exceeded. When this limit is reached, the spray pot shall be emptied and cleaned, and new material shall be mixed. GENERAL APPLICATIONAPPLICATIONPainting shall be carried out by airless spray and/or conventional air spray according to the manufacturer recommendation. Environmental Conditions Coatings shall not be applied when any of the following conditions exist: Wet surfaces, damp, moisture surfaces Relative humidity exceeds the manufacturer's recommendations or 85% Steel surface temperature is less than 3C above the dew point Ambient or surface temperature is above or below the manufacturer's recommended temperature for application or is greater than 40 C. The high temperature location where is not allowed to shut down for long time for blasting and re-coating. Therefore, the blasting and painting job shall be implemented online. If this is the case, the normal marine paint could not be used. So, CLJOC shall choose the suitable coating such as BELZONA-5851 for application on line.DUSTEvery possible precaution shall be taken to eliminate dust before and during painting process. Cleaning down immediately before apply coating is recommended by manufacturer following long periods between coats and following inclement weather. Cleaning down may be done by chloride free fresh water spraying, sanding paper or by other approved methods.PRIMER COATINGBlast cleaned surfaces shall be coated with one complete application of primer as soon as is practically possible, but in no case later than 4 hours after blasting provide the surface condition is SSPC-SP10 at the time of coating application. UHP water jetted surfaces shall be coated with one complete application of primer after dry surfaces up. Acceptable flash-rust degree before application: maximum M (atmospheric exposure) / M, preferably L (immersion). Please refer to ISO 8501-4.DRYNESSIn a proper state of cure prior to the application of successivecoats, materials shall be considered dry for next coating when manufacturer's technical representative has accepted the coat and the additional coat can be applied without the development of any detrimental film irregularities, such as lifting or loss of adhesion of the undercoat. The drying times as specified in the manufacturer's data sheets, will be observed at all times. RE-COATINGThe maximum and minimum re-coating interval specified in the manufacturer's data sheets, will be observed before successive coats are applied. The only exception to this may be after the application of a mist coat where the recommended re-coat interval may be reduced in accordance with the coating manufacturer's recommendations. Any thin spots or area missed in the application shall be recoated and permitted to dry before the next coat is applied. All areas such as external corners and edges, welds, bolts, nut and interstices (excluding galvanized surface) shall receive a "stripe" coat prior to application of the specified coat (excluding the inorganic zinc silicate primer) to ensure these areas have at least the minimum specified film thickness as to ensure continuity of the coating. The "stripe" coat shall be allowed to become touch dry prior to coating with the specified coat. When successive coats of the same product have been specified, alternate color shall be applied to ensure contrast for complete coating coverage and control of thickness during application. Tinting may be permitted when allowed by the Paint Manufacturer provided the tinting materials are not detrimental to the service performance of the coating or when the tinting of the final coat is not acceptable. MASKINGAll nameplates, manufacturer's identification tags, machined surface, finish flange faces, control valves, electric fixtures etc, shall be masked to prevent coating contamination. Special consideration shall be given to protect high alloy stainless steel such as 316L, 825 and duplex stainless steel surfaces so that overspray from coating does not contaminate the surfaces. STRIPE COATING TO ALL SHARP EDGES, CORNERS, WELDS, INTERSTICES ETC...All difficult to reach areas edges, corners, welding seam, interstices areas, etc.(excluding galvanized surface) shall be stripe coated prior to spray coating application of the specified coat (excluding the inorganic zinc silicate primer) to ensure these are have at least the minimum specified thickness as to ensure continuity of the coating. The stripe coat shall be allowed to become touch dry prior to coating with specified coat.SPRAY APPLICATIONOPERATORSOperators shall be skilled in the proper application technique for each coating. APPLICATIONPaint shall be applied in a uniform layer, with the gun held perpendicular to the surface being painted and with 50% overlap on the previous pass. EQUIPMENT CLEANINGSpray guns including spray tips, air caps, fluid tips, hoses and pressure pots shall be cleaned with suitable equipment cleaner recommended by the Paint Manufacturer before adding in new coating material. COMPRESSED AIROperation pressure shall comply with the recommendation of the coating manufacturer. Separate regulators shall be used to adjust the pressure and each regulator shall be provided with a pressure gauge operating properly at all times. Adequate moisture traps shall be on the air supply line of the compressor and other location as deemed necessary. Compressed air supply used for blasting cleaning shall be free from water and oil. A test in accordance with ASTM D 4285 shall be conducted to determine the presence of oil or water in compressed air used. BRUSH AND ROLLER APPLICATIONCoating shall be applied with a brush only at corners weld seam (Used only one type) after obtaining Cuu Long JOC approval. Brushes, maximum 150mm wide, shall be of the type, style and quality that will enable proper application of coating materials. Paint shall be worked into all crevices and corners, and runs shall be brushed out in order to eliminate air pockets, solvent bubbles or voids. REPAIR / TOUCH UP OF DAMAGECoatings damaged by fit up, cutting, heating, welding and mechanical works shall be cleaned and prepared by spot abrasive blasting to the specified SSPC-SP12or Wa2.5 near white metal blast cleaning and required anchor profile. Power tool cleaning must be achieved minimum Rz = 25microns and shall only be carried out with prior company approval. All damaged areas, before and after erection, shall be repaired using the original full paint system.Where paint has been damaged or is loosely adhering, the paint shall be re-blasted and applied the original full paint system. The surface to be repaired shall be feathered back progressively by fine sand paper, revealing each coat applied and will show sufficient of each coat to permitting satisfactory keying in of each repair coating applied. If repair to the coating of vendor supplied equipment is necessary it shall be carried out in accordance with the vendor's recommendations and after Company approval. All galvanizing damaged in fabrication, erection, assembly, handling welding and by other or other operations shall be repaired by spot blast cleaning and apply Company approved zinc primer. Where the repaired damaged galvanizing is part of full-coated galvanized item, the repaired area shall receive full coats of the same coating system applied to that galvanized item.INSPECTION / QUALITY CONTROL0. INSPECTIONTo ensure the quality control and painting inspection requirements are maintained during painting operations, inspection will be carried out by the paint manufacturer's representative in accordance with the requirements of this procedure. 0. VISUAL INSPECTIONIndividual coats and completed coating shall be visually inspected for appearance. Coating shall be free from excessive sagging, dry spray, pinholes, blisters and other types of coating application defects and shall be free of any coating damages. 0. FILM THICKNESSMEASUREMENTDuring coating application, the wet film thickness shall be spot- checked using a clean wet film gauge. The dry film thickness of each coat shall be measured using a coating thickness gauge such as Elcometer E-456 or equivalent. DRY FILM THICKNESS (DFT) VALUE.Five separate spot measurements, average of three readings, spaced evenly over each 10 square meter area to be measured for each coat. The average of five spot measurements for each such 10 square meters area shall not be less than the specified thickness.The minimum acceptable thickness at any single reading shall be not be less than 80% of the specified thickness. The averaged of the three (3) readings shall constitute one spot measurement where the thickness shall be equivalent or above the specified DFT. The thickness of each coat shall be determined prior to the application of subsequent coats in accordance with SSPC PA-2. The acceptable range of DFT shall refer to painting system as required in company specification. Thickness measurement of coatings on curved surfaces such as pipes, valve bodies shall be done using curve probe to the DFT Gauge and calibrated using certified foils/shims on the same curve surface to be checked. Pipe supports with usual geometry shall be inspected for the coating integrity and coating thickness measured with extended length and/or angle probe. Controls DFT with Inorganic Zinc silicate for prevent mud cracking. TEMPERATURE AND RELATIVE HUMIDITYTemperature and relative humidity shall be measured by means of a temperature gauge and a hygrometer using a humidity gauge such as Elcometer E-319, 116C, 114 Readings shall be taken prior to the commencement of blasting and/or painting and at regular intervals, if changes in climatic conditions occur. All gauges and recorders shall be calibrated and certified prior to testing. Gauges, which are of doubtful accuracy, shall not be used. SAFETYHydroblast cleaning uses high pressures. Extreme caution should be exercised with the equipment.Instruction and training of operators about correct use and equipment operation is essential.Surfaces, other than metal, can be damaged with high pressure water and should be protected from effects of the high pressure water blast.Blasting operator shall be equipped with rain suit, suitable long-sleeved protective clothing preferably coverall, safety boots, air-fed full face blasting helmet/hood, dust respirator, leather gloves and safety goggles.
