Appendix 1 Colour Identification for Jasmine Platforms The topcoat colour for structural steel, vessels, piping and equipment shall be as listed in the following table. The colour codes referenced in the following tables are from BS 4800. Note that PVC tapes shall not be used for colour banding purposes on stainless steel lines. All coated, non-insulated piping shall have a white (00 E 55) topcoat with painted colour coded banding as per the table below. Uncoated firewater lines shall be identified by painted on colour banding as per the following table. Appliances and flanges shall be coated red as per the table below. For piping under insulation reference shall be made to JA00-03-AD-00009. Insulated CRA piping (i.e. 316L SS, DSS, SDSS, etc) and carbon steel piping subject to a TSA coating system do not require the topcoat over the sealer and therefore the requirement for the white topcoat colour does not apply. Insulated CRA and carbon steel piping subject to a non-TSA coating system shall have the full coating system applied including the requirement for the white (00 E 55) topcoat.

This Specification supersedes all existing Specifications and revisions and shall be used on all COMPANY UK facilities. This Specification defines the requirements for surface preparation, application and inspection of coatings for new build and maintenance coating of structural steel, vessels, plant, equipment risers and piping used on all Company Installations. Exclusions: This Specification does not cover the following: 

Coating the internal surface of vessels (For internal linings, refer to the COMPANY Specialist.)



Coating of internal surface of accommodation modules



Protection of subsea pipelines

 Protection of package equipment This Specification addresses general requirements for new construction and maintenance coating including coating application, coating systems tables and colour coding. Where applicable, requirements specific for individual installations are covered by the supplementary sections. However, it shall be read and interpreted as a document and not on an individual section basis. This specification does not specify particular suppliers. All specifications are generic. It is the responsibility of the applicator to ensure compliance with this specification, assure compatibility of the products required to build the full coating system and the selection of coating manufacturer. The Company reserves the right to review and, if necessary, reject the coating manufacturer nominated. Coatings selected for New Construction by the Contractor shall provide a minimum of 15 years service before 1st major maintenance unless otherwise specified by the Company.-

GENERAL 2.1

Contractor Responsibilities 1

Rev 2 June 2009

The term Contractor means the Contractor directly responsible for ensuring the completion of the work. For onshore and offshore projects the Contractor may be the Company’s Engineering Services Contractor using a Nominated Coating Applicator. Alternatively it may be another Engineering Sub-Contractor or Equipment Manufacturer using a Sub - Contracted Coating Applicator. For offshore projects the Fabric Maintenance Services Contractor will be both Contractor and Applicator, or as a nominated sub-contractor of the Engineering Services Contractor. Any nominated sub-contractor shall be agreed with the Company. The use of a sub - contractor does not alleviate the Contractor of his responsibility for all requirements given in this specification including documentation The Contractor shall submit Work Packs or Documentation Packages incorporating Quality Plans covering all aspects of the coating works for review and approval before the commencement of work. A typical Quality Plan Data Sheet is included within this Specification for Contractor guidance. Specific queries on quality plans shall be referred to the Company Representative For small Projects, a Quality Plan may not be required. In such cases, the Company Representative will advise on Inspection requirements prior to work commencing. The Contractor shall be responsible for ensuring that all materials and equipment are provided to perform the work within the necessary timescale and to the required standard. Equipment required for coating application shall be fully maintained, calibrated and in good working order prior to commencement of work. Surface preparation and coating shall be performed by experienced and skilled labour, together with competent supervision. Competency shall be demonstrated through the National Vocational Qualifications, NACE or a recognised coating accreditation system.

Where required by this specification coating systems and coating operatives shall be prequalified Where items are coated at the Contractor, Sub-Contractor’s, or applicators premises, the finished coated item shall not be moved until the final coat has cured. The time required for curing shall be based on the Manufacturer’s Data Sheets which shall be incorporated in any time estimates given. Components which have been coated onshore shall be fitted with flange protectors and protection to pre-prepared weld butts. The Company reserves the right to appoint a 3rd party Coatings Inspector to witness all or part of the coating process. The Contractor shall raise all technical queries concerning coatings in writing to the Company Representative for approval or otherwise

Pre-application Activities Pressure equipment, piping, etc, which requires stress relief, welding or pressure testing shall not be coated until all such activities are satisfactorily completed, unless authorised to do so by the Company Representative. Where required coating systems not previously applied by the contractor shall be prequalified as required by this specification. The applicators nominated for coating application shall be similarly qualified for application of these systems.

Removal of minor defects (i.e. which can be removed by hand filing) shall be authorised by the Company Representative. However, no grinding of pressure components shall be performed without approval of the Company Materials and Corrosion Specialist. Where defects have been revealed during blast cleaning, and dressing has been performed, the dressed area shall be re-blasted to the specified standard. All welds shall be inspected and if necessary repaired prior to final blast cleaning of the area. Surface pores, cavities etc. shall be removed by suitable dressing or weld repair after consultation with COMPANY Materials and Corrosion Specialist. Any oil and grease contamination shall be removed in accordance with SSPC SP 1 solvent cleaning, prior to blasting operations.(see 4.2) Degreasing of austenitic steels shall only be carried out using halide free solvents. Where the pipework and/or vessels are in service, the requirements of procedure “Surface Preparation of Corroded Equipment” CPUK-INT-P-014” shall be adhered to. Any crevices created between structural members particularly stitch welded caused by two surfaces in intimate contact shall be brought to the attention of the Company Representative, who may authorise sealing by welding or by a mastic approved by the specific coating Manufacturer. All equipment and structure shall be fully protected from over blast, grit and dust contamination. Specific items to be protected are detailed in Section 2.3. The compressed air shall be free of water and oil. Adequate separators and traps shall be provided, installed in the coolest part of the system. All traps, separators and filters shall be cleaned regularly, i.e. daily or more frequently if required. Under no circumstances shall the temperature of the compressed air be allowed to exceed 110°C. Blasting nozzles shall be discarded and replaced when the internal nozzle diameter has increased through wear by more than 50% of the original diameter. Abrasive blast cleaning equipment shall be an intrinsically safe construction and equipped with a remote shut-off valve triggered by the release of a dead man's handle at the blasting nozzle.

4.2

When the presence of lead based coatings are suspected, samples shall be taken and sent for analysis. If the results of the tests show that the lead content is greater than 3.3% w/w the work area shall be graded as a lead hazard and the appropriate safety measures shall be put in place for both the personnel on the workface and the adjacent personnel. All material removed from the site shall be contained and disposed of as hazardous waste.

Treatment Prior to Surface Preparation Prior to surface preparation for coating, all surface contamination shall be removed. Heavy grease or oil deposits shall be scraped off or wiped off, using water soluble degreaser. The entire surface shall then be scrubbed with a nonflammable, proprietary oil emulsifying agent. This shall then be rinsed off, using potable water. Alternatively, pressurised hot water containing oil emulsifying agent may be used after approval by the Company Representative. Final wash down shall be with hot water only. All surfaces shall be allowed to dry before work proceeds. The presence of salt contamination shall be checked in accordance with the method presented in Section 4.3, Item 9. Where the test indicates that the salt contamination is greater than 50mg/m2, the surface shall be re washed. When a habitat is required for coating, water washing shall be performed at a stage where water can be drained easily from the area. A black light test shall be carried out to confirm the removal of grease and oil contamination from the surface to be blast cleaned. Weld splatter and any surface breaking defects shall be removed after consulting the structural engineer by grinding prior to surface preparation taking place. see section 4.1 item 2..

Rev 2 June 2009

Surface preparation by grit or slurry blasting shall not take place on surfaces which are wet or may become wet before application of primer; when RH is greater than 85%; or when the metal surface temperature is less than 3 deg. C above the dew point. Steel surfaces which are prepared by dry grit blasting will be blasted to ISO 85011, SA 2½, unless otherwise specified. Preparation grades shall be as detailed on the coating system tables within this Specification. The surface profile shall be as detailed by the manufacturers as requested in Section 3 item 6. Otherwise an angular profile of 50 to 75µm shall apply. For TSA coatings an angular surface profile of 75 to 100µm shall apply. Abrasives for blasting shall be selected, to give the surface amplitude specified. Metallic or expendable grit may be used. If expendable grit is used, it shall be free from dust, salts, silica and other impurities and shall only be used once. Re-usable abrasives shall be regularly checked and sieved, to remove debris and contamination. The Company Representative may specify expendable grit; if it is considered that re usable grit will impair performance. The pressure and flow rate of compressed air shall be sufficient to ensure efficient cleaning (minimum time and grit consumption), to the required standard. Strict adherence to pressure indicated in COMPANYS “Surface Preparation of Corroded Equipment” procedure CPUK-INT-P014.

Page 13 of 65


CPUK-INT-P-020

The Company Representative reserves the right to specify grit size, nozzle size and nozzle pressure, in cases where it considers optimum efficiency of blasting is not being achieved. The Contractor shall use angled blast nozzles where necessary, to successfully blast difficult areas. Blasting nozzles shall be discarded and replaced when the internal nozzle diameter has increased through wear by more than 50% of the original diameter. Abrasive blast cleaning equipment shall be an intrinsically safe construction and equipped with a remote shut-off valve triggered by the release of a dead man's handle at the blasting nozzle. A selection of angled nozzles shall be available at Company installations during major coating works. On completion of blast cleaning to the required standard, the substrate shall be cleaned thoroughly. Spent abrasive and dust residue shall be removed by brushing and vacuum cleaning, or blowing with clean dry compressed air. The cleaning shall be carried out in such a manner to ensure that no contamination of surrounding areas occurs during this process. The dust level on the blast cleaned surface shall achieve a minimum quantity rating of 3 in accordance with ISO 85023 Section 6 prior to the commencement of coating. For TSA coatings the dust level on the blast cleaned surface shall achieve a minimum quantity rating of 1. Checks on dust levels shall be made on each component and at least once per 100m2 of surface to be coated. Dust checks shall also be performed during the progress of work, a minimum of 3 times per day. Dust assessing tape shall be retained for review and attached to daily inspection reports. Coating application shall be performed, before deterioration of the prepared surface occurs and within 4 hours of completion of blast cleaning. Soluble salts: The maximum allowable total salt levels on grit blast cleaned surfaces are summarised in the Table, below;

The method for assessment of surface salt contamination shall be in accordance with ISO 8502-6 and ISO 8502-9. Special attention shall be given to areas of previous corrosion or to areas where water has become trapped and dried out. Checks on salt levels shall be made on each component and at least once per 100m2 of surface to be coated. Salt checks shall also be performed during the progress of work, a minimum of 3 times per day. 10

4. 4

During blasting, particular attention shall be paid to areas where corrosion/pitting is present. Such areas may contain high concentrations of soluble iron salts as a result of exposure in a marine atmosphere. Consequently a salt contamination check shall be carried out, as presented in Item 9, above. Coating systems applied over such contamination will suffer from a significant reduced performance. Pitted areas revealed after blasting, shall be tested for soluble iron salts, per the method stated in item 9. Where a concentration greater than the maximum valued given, these areas shall be washed with potable water until only a trace indication is present.

Wet blasting/UHP Water Jetting (maintenance coatings only) Wet Blasting using a grit/ water mix (slurry) shall be used to remove very heavy surface corrosion product or soluble salt contamination where dry blasting is not allowed. Only potable water shall be used for surface preparation. In such cases, a written procedure shall be submitted by the Contractor for approval by the Company Representative prior to commencement of such work, and included in the Work Pack. Steel surfaces prepared by slurry blasting do not look the same as those produced by dry abrasive blasting. Therefore slurry blasting tends to look dull, even before they flash rust. In addition steel with active corrosion pitting will show a

Rev 2 June 2009

Page 14 of 65


CPUK-INT-P-020

mottled appearance after blasting. Mottling occurs when the corrosion products are washed out of the pits leaving a brighter patch within the pits, with the surrounding area left a dull grey colour. The pattern is the reverse of that left by dry abrasive blasting where anodic pits are often dark due to corrosion products not being removed. Steel which has been prepared by slurry blasting dries off and will quickly change the appearance of the substrate. In the absence of a recognized visual standard the surface finish shall be equivalent to ISO-8501-1 SA 2½, the surface profile shall be in accordance with that specified for the coating system together with acceptable levels of flash rusting. In some instances, surface preparation may be carried out using Ultra High Pressure water blasting. The pressure of the water shall be at least 30,000psig and the jet directed through either a fan jet or a rotating nozzle dependant on the surface being prepared. The standard of surface preparation shall be generally in accordance with SSPC SP12. This standard shall only be used for surface cleanliness determination. Ultra High Pressure water blasting will only remove existing coatings, corrosion products and salt contamination from the surface to reveal either the original profile or provide a clean surface. 4.5

Power Tool Surface Preparation (maintenance coatings only) The use of Power tools shall be strictly in accordance with Surface Preparation of Corroded Equipment procedure, CPUK-INT-P014. Power tool cleaning, i.e. needle guns, rotating wire brush, discs, etc shall only be used when all other methods of surface preparation cannot be used prior to coating application to this standard and shall be agreed with the Company Specialist. 1

4. 6

Environmental constraints/limits for power tool cleaning shall be as detailed in Section 4.3.1. Initial preparation may be allowed when environmental conditions are unacceptable for those specified at the discretion of the Company Representative Steel surfaces shall be prepared to SSPC SP 11 preparation grade for all coating systems where power tool preparation is specified. Care shall be taken to ensure the substrate does not become polished After preparation to the required standard, the substrate shall be cleaned thoroughly by brushing and vacuum cleaning, or blowing with clean dry compressed air. Surrounding areas shall be protected, to prevent contamination. Areas which cannot be power tool cleaned shall be manually prepared by hand with the same requirements as power tool cleaning. The pressure and flow rate of compressed air shall be such that the recommended RPM of any air driven power tool is not exceeded. All disc wheels and accessories shall be correctly rated for the RPM of the tool.

Solvent Cleaning Where solvent cleaning of the substrate is required, for the removal of oil/grease, SSPC-SP1 “The Society for Protective Coatings Surface Preparation Specification” Solvent Cleaning shall apply. The use of solvents shall be in accordance with COMPANY HSE procedures. The preference is to use water soluble degreasers.

4. 7

Galvanised Surfaces The preferred method of surface preparation for new and aged (weathered) galvanising is by sweep blast cleaning, to remove all surface contamination and mechanically key the surface. Care must be taken to ensure the galvanising is not removed during sweep blasting.

4.8

Temporary Protection In exceptional circumstances, the Company Representative may require coating to provide temporary protection of equipment. In such cases, surface preparation may

CPUK-INT-P-020

The elapsed time within which a coating can be effectively applied after all components of the coating have been thoroughly mixed. A coating material intended to be applied as the first coat on an uncoated surface. The coating is specifically formulated to adhere to and protect the surface as well as to produce a suitable surface for subsequent coats. The time period during the drying and curing of a coating in which a subsequent coat can be applied successfully.

RH (Relative Humidity)

Percent water in air at a given air temperature.

Rust Creep

The penetration of a coating and the spread of delamination or corrosion from a scribe or holiday in the film.

Shelf Life

The manufacturer’s recommended maximum storage time for a given product under recommended storage conditions

Site

The location of coating operations approved by ConocoPhillips UK Limited

Splash Zone

The portion of a marine structure that is intermittently wetted by waves, wind-blown water spray, and tidal action. Brush applied coat to sharp edges, welds, etc., The stripe coat is intended to give those areas sufficient film build to resist corrosion. The surface area of a marine structure that is always covered with water and extends downward from the splash zone and includes that portion of the structure below the mud line. The irregular peak and valley profile on the surface of bare metal that results from abrasive blast cleaning or power tool cleaning.

Stripe Coat Submerged Zone Surface Profile Sweep Blasting

A light grit blast of a surface intended to remove all gross contamination and loosely adherent coatings, without removing all tightly adherent corrosion and adherent coatings.

Thinner

Liquid added to ease application of coating or adjust viscosity.

Vendor

The supplier of packaged equipment ready for installation.

WFT

The thickness of a coating measured immediately after application before any solvent has evaporated or drying has taken place. A general term used for inorganic zinc-rich coatings and organic zinc-rich coatings used as a primer.

APPENDIX 5 - SPECIFIC REQUIREMENTS FOR TSA APPLICATION Coating Materials The aluminium metal feed wire for thermal spraying shall be composed of 99.9% pure aluminium in accordance with BS2901 Part 4 Grade 1050A, Gov. Std 1B in Table 2 of BS 1475. The aluminium metal wire shall be supplied with product data sheets and quality control certificates, and shall be marked with the manufacturer's name, manufacturing standard, metal composition, weight and manufacture date. The materials for sealing the aluminium metal coating shall be suitable for the intended use and service conditions. Application TSA sprayers shall follow the approved tests outlined in ISO 14918

Adhesion Test Applicable to the TSA coating only During the TSA spray process, steel companion coupons shall be used to assess the adhesion to the steel substrate by means of pull-off test, according to ISO 16276-1,or ASTM D 4541. If the Company specifies the adhesion test to be conducted directly on the work piece, the adhesion strength to the substrate shall be measured according to ASTM D 4541 using a self-aligning adhesion tester or approved equivalent. All adhesion measurements shall be taken on unsealed TSA. The Hydraulic Adhesion Tester (HATEor PAT) Tester latest Model shall be used. Three dollies shall be bonded to each test plate, using TUFLOC cynoacryllic adhesive. Care shall be taken to ensure the adhesive completely seals the metal sprayed surface. The test surface shall be coated completely, to provide a 100% adhesive sandwich between dolly and test surface. The glue shall be left to cure for the recommended time at ambient air temperatures. At least three adhesion measurements shall be taken. If the pull-off adhesion test is done on the actual work piece, any damage shall be repaired according to the repair procedure, below. Measured adhesion values shall be corrected, as required, if curved test dolly surfaces are used. The minimum TSA adhesion strength shall be as specified in the Table below. If the bond strength is less than the minimum specified value, the degraded TSA shall be removed and reapplied. When the pull-off adhesion test is conducted on a production-coated component, the measurement shall be taken when the specified value is attained or the coating adhesion fails, whichever occurs first. Once the specified value is reached, the pressure from the tester shall be released, and the test dolly removed without damaging the TSC. Adhesion test areas shall be repaired if required, in accordance with repair methods detailed below. Measured adhesion values shall be corrected, as required, when curved test dolly surfaces are used.

2)

For pre-qualification, surface cleanliness shall be Sa 2½ .

Heated tongs shall be used to remove the test dollies from the aluminium coated test piece/surface. TSA Repair Method: If the TSA has been damaged and bare substrate metal may be exposed, the coating repair shall be repaired as follows; 1 – Solvent clean: All oil or grease contamination shall be removed by solvent cleaning. Solvents shall not cause detrimental effects on the substrate material and shall not leave any residue film on the substrate. Solvent cleaning may be accomplished by wiping, brushing or spray. Precautions shall be taken to protect any parts that may be affected by the solvents. Other necessary safety precautions shall also be taken when handling solvents. 2 – Scrape off loosely adherent paint/TSA: A paint scraper blade shall be pushed underneath the loose TSA to push and scrape away all loosely adherent paint and TSA until reaching a well-bonded TSA area. 3 – Abrasive blasting The surface to be repaired shall be abrasive blasted to a white metal finish with an anchor profile of more than 63 m. The blasting nozzle shall be kept perpendicular to the work surface. Angle blasting into the TSC-steel interface may separate the bonded TSC from the substrate. 4 – Feathering: A 5.0 cm to 7.5 cm border shall be feathered by angle blasting into the undamaged TSA area. 5 – Apply TSA: The TSA shall be applied in accordance with (4). Do not apply arc-spray TSC over flame-spray coatings because the greater energy of arc spraying may delaminate marginal flame sprayed coatings. 6 – Sealer and topcoat: Sealer and topcoat shall be applied in accordance with the System requirements. Coating repairs shall be re-inspected to ensure compliance with the requirements of this Specification. Where only the sealer or topcoat have been damaged, the surface shall be prepared by abrasion with #60 abrasive paper until a clean bright surface is evident. All edges of existing coatings shall be feathered. The appropriate sealer / topcoat system shall then be reapplied to the damaged areas.
