PREFACE Woodside Energy Ltd. (WEL) has developed a suite of Engineering and Technical Standards and Guidelines. It is intended that these reflect the most suitable engineering practices for use on all new WEL facilities as well as the modification of existing facilities. The application of the Standards is mandatory. The application of Guidelines is to support the implementation of the Standards. They are considered best practice, but are not mandatory. The Standards are based on the experience acquired by WEL personnel and contractors during WEL’s involvement with the design, construction, operation and maintenance of WEL processing units and facilities. Where appropriate, the Standards are based on or make reference to national and international standards and codes of practice. The objective of this publication is to ensure the overall integrity of engineering design and to achieve maximum technical and economic benefits through the standardisation of engineering and technical practices. The use by WEL contractors or manufacturers/suppliers of the Engineering and Technical Standards contained in this publication does not relieve them of any responsibility whatsoever for the quality of design, materials and workmanship that they have been engaged to provide. Where the standards to be used for a certain application are not provided for in this publication, WEL expects that the standards that are used will achieve the same level of integrity as reflected in this publication. If WEL contractors or manufacturers/suppliers have any doubt as to the relevant standard to use, then they must consult WEL, however they will remain responsible at all times for the use of the most appropriate standard. Specific requirements may be added as an addendum to these Standards and Guidelines for various projects. Project specific requirements must not depart from the requirements of the Engineering and Technical Standards contained in this publication. Where changes or additions to these Standards are required, they must be raised as a deviation and presented to the WEL Technical Authority for consideration. WEL grants the right to use these Standards and Guidelines to WEL’s consultants, contractors and suppliers who are contractually authorised to do so and to any tier of contractor to its consultants, contractors and suppliers who are contractually required to comply with them. DISCLAIMER WEL and its joint venture partners disclaim any liability of whatsoever nature for any damage (including injury or death) suffered by any company or person whomsoever as a result of or in connection with the use, application or implementation of any standard, combination of standards or any part thereof contained in this publication.

APPENDIX 1 – SUPERCEDED HISTORICAL STANDARDS.................................................. 60




1 INTRODUCTION 1.1 SCOPE

This standard covers organic/inorganic and thermal spray protective coatings as well as passive fire protection of all Woodside equipment and structures for both new construction and maintenance situations for both offshore and onshore. It includes the requirements with respect to protection against corrosion of both ferrous and non-ferrous materials. It covers facilities such as fixed leg production platforms, floating production, storage and offloading (FPSO) facilities and facilities on the coastline such as jetties, quays and onshore plant. This document supersedes those historical standards listed in Appendix 1 including previous versions of W9000SM001. The standard defines the minimum acceptable surface preparation, coating application and quality assurance and control for the application of surface coatings and is applicable for new construction, modifications and maintenance of WEL facilities. All paint and coating systems to be used shall meet the qualification requirements and the minimum coating system requirements as specified in this document. It is the responsibility of the Principal to carry out the review and acceptance of the project and quality plan in order to ensure that the painting work is executed in accordance with this specification To achieve long term service life of the protective coating system, it is essential that full attention shall be given to:

• Using qualified and fully tested coating systems

• The quality of surface preparation

• Application of the coating system.

• Quality assurance, quality control and the professional skill of painters are essential for this process.

For installations with a design life of 25 years or more, unmanned offshore installations and parts difficult to access for maintenance after installation, special ‘life time’ coatings such as thermal sprayed aluminium shall be considered in consultation with the Materials, Inspection & Corrosion Engineering discipline. TSA is generally recommended for primary and secondary structural steel. The application of TSA to tertiary steel and pressure vessels and piping would be on an as needs basis. For facility design lives less than 20 years conventional 3 coat systems comprising zinc rich primers, high build epoxy second coats and a gloss topcoat are recommended. These coatings are expected to require maintenance programmes commencing within 5 – 7 years of first application and on an on-going basis thereafter through to end of facility life. Topics of a general nature regarding painting and coating such as the supply of labour, equipment, personnel safety gear or the use of sub-contractors have not been included in this document. They should be included under the General Terms and Conditions of a contract.




The standard defines minimum application parameters and procedures for each specification. It is considered that specialist applicators and the paint supplier are familiar with these requirements. The surface preparation standards and coating film thickness presented are the minimum requirements acceptable to Woodside Energy Ltd. Woodside and other users recommend the systems and applicable coating products as detailed in Sections 8, 9 & 10 on the basis of laboratory trials and many years of in-service experience. They have provided cost effective corrosion protection. Alternative systems are permitted through the deviation process.

NOTE: Many coating systems require time to cure before being available for service. This period should be recognised when preparing delivery schedules.

1.2 EXCLUSIONS This specification is not applicable to:

• Subsea pipelines

• Subsea structures (wellheads, manifolds, PLEMs etc)

• Risers of offshore pipelines being coated with a special coating (e.g. Monel or Cu impregnated heat cured chloroprene rubber) except those parts of the riser above the special riser coating

• Temporary construction items for which only a zinc rich primer is to be applied

• Internal coatings of tubing, drill pipe or pipelines (including flow coatings)

• Fusion bonded powder coating

• Equipment and components with a service temperature below minus 170 oC and over 450 oC.

• Galvanised items except handrails and other items specifically specified to be painted

• Valve stems, flange faces and machined contact surfaces

• Stainless steel and non ferrous materials specifically specified without coatings

• Anodes

• Architectural finishes

• Rubber and special purpose linings

•

1.3 REGULATORY CONSIDERATIONS If international and/or regional regulations exist in which some of the requirements may be more stringent than in this Standard an assessment shall be made to determine which of the requirements are the more stringent and which combination of requirements will be acceptable as regards safety, environmental, economic and legal aspects. In all cases the Contractor shall inform the WEL Technical Authority.




1.4 DEFINITIONS The definitions below shall apply:

• The Contractor is the party that carries out all or part of the scoping, budgeting, procurement, access, surface preparation, coating application, quality control and touch ups as identified in this specification. The Principal may undertake all or part of the duties of the contractor.

• The Manufacturer/Supplier is the party that manufactures or supplies equipment, materials, coatings and services to perform the duties specified by the Contractor.

• The Principal is the party that initiates the project and ultimately pays for its design and construction. The Principal will generally specify the technical requirements. The Principal may also include an agent or consultant authorised to act for, and on behalf of, the Principal.

• The words shall / must / will indicate a mandatory requirement. • The word should indicates a recommended course of action. • The words may / can indicate one acceptable course of action. • WEL Technical Authority (TA) in this document refers to the Materials/Inspection/Corrosion

2 STANDARD 2.1 WARRANTY

Contractors, undertaking painting and/or coating work, which are to be carried out in accordance with this standard, shall guarantee the quality of their coating work. Before any painting or coating work commences, warranty period and coating condition shall be agreed with the Principal. Usually a warranty period of five (5) years or ten (10) years is required for special coatings such as thermally sprayed aluminium. The use of coating systems as described in this standard and approved by the Principal shall not affect the warranties to be agreed by the contract parties involved. If reference areas are proposed and agreed, they shall be in accordance with requirements as specified in ISO 12944-7 Clause 7 and ISO 12944-8 Table 1, No.1.13. Surfaces that have deteriorated beyond the acceptable level of breakdown within the warranty period shall be repaired by the Contractor and he/she shall bear the cost for materials, equipment, labour, onshore transport, onshore lodging and onshore storage necessary for the repair. Only surfaces that have suffered from mechanical damage or chemical spillage as a result of operational activities fall outside this warranty. Initial acceptance of any new coating work by the Principal will not relieve the Contractor of his obligations under this section until the final inspection has been carried out and acceptance of the completed work has been agreed in writing. A final inspection shall be carried by a party to be agreed between the Contractor and the Principal before expiry of the period of a warranty agreement regarding the coating work. In case of a dispute on the condition of the coating work that has been inspected, an agreed independent expertise body shall conduct a review inspection at the Contractor’s cost. Both the Principal and the Contractor shall accept the findings of the inspection by this independent consultant.

2.2 REVISIONS TO STANDARD As paint technology advances paint formulations and application techniques and procedures change. When such changes or other requested modifications affect this standard, single page revisions will be issued to all holders of a controlled copy. (NB Persons using uncontrolled copies should check the current status of their document). A complete review of this standard shall be carried out, as a minimum, at 5 years intervals.




2.3 DEVIATION FROM STANDARD Any change or variation to the requirements within this standard shall be submitted in writing to the TA for review and approval a minimum 2 weeks prior to any work commencing. This shall include substitution of other coating systems or colours not included in the standard or any change or relaxation to surface preparation, coating application, extent of application or quality control.

Scaffolding and staging shall be constructed so that operators are able to stand erect with body and arms free of obstruction and so that sufficient access is provided for coating process and quality control inspections. Care should be taken to maintain a clear and uncluttered work area to reduce the risk of falling or tripping or dislodging items from above deck work areas.




Safety harnesses, standby personnel and any other appropriate safety precautions must be used when applicable. Rope access may be used where appropriate and with the proper procedures.

3.2.12 Work Permits The appropriate work permit systems shall be followed. This may involve the use of Job Hazard Analyses (JHAs).

3.2.13 Selection of Coatings and Application Methods Woodside has a global responsibility for the protection of the environment and will use products and application methods that are environmentally ‘friendly’, providing they meet the minimum engineering requirements for achieving corrosion protection. The specifier must understand the systems and their relation to original condition, surface preparation, profile and sequence of coats.




4 SURFACE PREPARATION 4.1 GENERAL

All edges shall be ground to a minimum radius of 2 mm or otherwise agreed with the Principal and Flame cut areas should have been ground flush. Weld spatter shall have been ground flush. Cleaning of surfaces shall, as a general rule, be done by dry blast cleaning (hereafter referred to as blast cleaning) as outlined in AS 1627.4 to achieve a class 2 ½ (ISO 8501-1 Sa 2 ½). The surface profile and the anchor pattern shall be in accordance with the requirements of this Standard. Welds in immersion areas shall conform to NACE RP 0178-2003 Surface Condition C. Welds in non-immersion areas shall conform to NACE RP 0178-2003 Surface Condition D. Fabrication should be complete before surface preparation begins. However, surface preparation and application of the base layers of the specified coating system before assembly will be allowed. Prefabrication primers are allowed. However, after assembly these primers shall be removed by abrasive blast cleaning and the surface shall be blasted to the initial specified surface cleanliness unless otherwise agreed with the Principal. Alternative surface cleaning methods are only acceptable after written approval of the Principal. Alternative surface preparation such as power tool cleaning is not acceptable for areas difficult to access such as areas exposed to water, steelwork to be insulated or to be buried and internal surfaces of equipment and tanks. Stainless steel surfaces shall not be treated with carbon steel cleaning tools.

4.2 PRETREATMENT Salt contaminated surfaces (> 50 mg/m2 for atmospheric steel and > 25 mg/m2 for immersion zones) shall be washed down with a potable water jet wash ((e.g.7-28 MPa) to remove soluble surface contamination to below acceptable levels. Oil, grease, wax, dirt and other foreign matter shall be removed by cleaning and degreasing of metal surfaces in accordance with AS1627 Part 1 or approved equivalent international standard. All bolt holes shall be drilled and their edges ground to remove sharp edges and solvent cleaned prior to the commencement of blast cleaning. Solvent cleaning shall be carried out in accordance with AS1627 Part 1 (SSPC-SP1). All welded areas and appurtenances shall have welding flux removed from crevices prior to commencement of any surface preparation. Any weld undercut or other crevices not acceptable to the fabrication standard shall be reported and repaired. All weld spatter, temporary attachment points, surface defects etc shall be removed and ground flat.




Labels, marker plates, valve stems, flange faces, glass, mechanical seals, rubber gaskets and other sensitive areas shall be covered to prevent damage during the coating process. Protective materials shall be removed after coating is completed. Dust shall be removed by blowing with clean, dry, oil free air or by vacuum cleaner. For maintenance, firmly adherent coating systems may be left on the substrate providing their edges are suitably 'feathered'.

4.3 ABRASIVE BLAST CLEANING Applies to all surfaces listed and where appropriate within each system identified in sections 8 & 9.

4.3.1 Grades of Surface Finish

The recognised surface finish grades are summarised in the table below.

Table 4.1 Surface finish grades

Surface finish grade ISO/AS 1627.4 SSPC NACE White metal Sa 3 SP-5 1

Near-white metal Sa 2.5 SP-10 2 Sweep blast cleaning Sa 1 SP-7 4 Solvent cleaning - SP-1 - Power tool cleaning St 3 SP-3 Power tool cleaning to bare metal

- SP11 -

Water jetting - SP-12 5 Wet abrasive blasting - TR2 6G198 “Sweep” blasting may be approved to slightly roughen (5 – 10 micron profile) previously coated surfaces that have exceeded re-coat times. All loosely adhered coatings remaining after sweep blasting must be entirely removed prior to any coating operation. If maintenance or re-work is to be carried out adjacent to a coated surface, the dressed areas shall be re-blasted to provide adequate paint key. The blast cleaning shall carry over onto the secure surrounding coating for not less than 25mm all around and the edges shall be chamfered by a method approved by Woodside, following a written submission by the Contractor. All blasting residue (spent abrasive, dust, rust and paint) shall be gathered and disposed of in an approved environmentally acceptable manner.

4.3.2 Dry Abrasive Blast Cleaning Blast cleaning of carbon steel surfaces shall comply with AS1627 Part 4, Class 2.5 (or ISO 8501-1 approved equivalent international standard) at the time of coating unless otherwise nominated.




Blasting abrasive shall be dry, clean, free from contaminants and of a type and size adequate to give anchor pattern amplitude of 40 to 75 microns (or as specified). The abrasive conductivity as assessed by ISO 11127-6 shall be 25 mS/m maximum when used on carbon steel and 150 μS/m for stainless steel as per ISO 11127-7. For new construction work abrasive conductivity shall be verified daily and with each new batch of abrasives. For maintenance work the proposed frequency of the conductivity determination test shall be submitted in writing for Woodside Materials/Inspection Group’s approval.

4.3.3 Wet Abrasive Blast Cleaning Wet abrasive blasting may be permitted with prior approval from Woodside. Wet abrasive blasting shall be in accordance with AS1627 Part 4 Section 3.2. Water for wet abrasive blasting shall be fresh potable water. The cleaned surface should be washed off immediately after blast cleaning using fresh water. Only after written approval of the Principal, a suitable corrosion inhibitor such as mass fraction 0.3 % sodium nitrite with mass fraction 1.2 % ammonium phosphate may be used to prevent flash rusting. Chromate inhibitors shall not be used. However, the paint Manufacturer shall approve the use of an inhibitor or the removal of residues of the inhibitor before painting. The cleaned surface shall be dry at the time of painting. Particular care shall be taken to dry areas which are not self-draining, so that water collected is removed. Any existing protective coating shall be properly protected to prevent any possible damage.

4.4 ULTRA HIGH PRESSURE WATER CLEANING (MAINTENANCE ONLY) Where abrasive blast cleaning is deemed impractical or unsuitable by Woodside for maintenance/HSE purposes, and where the surface has been previously abrasive blast cleaned, ultra high pressure water cleaning may be substituted in consultation with Woodside. The ultra high pressure-cleaning unit shall be capable of a minimum operating pressure of 270 MPa and shall have a proven effective performance. Oil, grease, wax, dirt and other foreign matter shall be removed by cleaning and degreasing of metal surfaces in accordance with AS1627 Part 1 (or approved equivalent International standard) prior to ultra high pressure cleaning. Where black spots occur in pits or other surface defects, the surface shall be cleaned again at higher pressure to remove these defects caused by residual salts. Ultra high pressure water cleaning shall only be used where compatible coating systems are specified. The contractor shall provide evidence of a robust safety system for protection of operators and personnel in the vicinity of the unit. The minimum required standard of surface preparation is NACE No. 5 /SSPC-SP 12 WJ-2 with no more than a light flash rust for spot repair and WJ1 with a light flash rust for full strip and re-coat. An acceptable alternative is the International Paints Hydro blast standard with a HB 2 ½ L being the minimum acceptable standard.




4.5 OTHER CLEANING METHODS FOR CARBON STEEL SURFACES Where applicable, steel surfaces may be mechanically cleaned using power tools such as flap or disk sanders, etc. Care needs to be taken as these items can lead to polishing of the surface. Hand power tooling shall be restricted to small areas only following approval from the Principal. For maintenance painting this shall be further restricted to non-pressure containing components only. Should power tooling be necessary, power tool cleaning should be performed according to AS1627, Part 2, (or approved equivalent international standard) with a surface finish to ISO 8501-1, Grade St 3 or equivalent. Prior approval shall be obtained from Woodside Materials/Inspection Groups before any of these methods of surface preparation are used. If these methods are approved, inorganic zinc silicate primer, where specified, shall be substituted with epoxy zinc rich primer or a primer more surface tolerant.

4.6 GALVANISED STEEL SURFACES All spikes and dross shall be removed and all edges shall be free from lumps and runs. All galvanised surfaces that are to be additionally coated shall be solvent cleaned in accordance with section 4.2 and brush/sweep abrasive blast. A suitable etch primer may be used as an alternative to brush abrasive blasting. If for any reason the galvanised products have been allowed to weather prior to application of the topcoat, the surface shall be pre-cleaned in accordance with the following requirements. High-pressure water jet wash (17 to 28 MPa or 2500 to 4000 psi) and dry using dry compressed air. Solvent clean all surfaces in accordance with Section 4.2. Galvanised surfaces that are showing signs of red rust shall be prepared in accordance with the appropriate system for carbon steel.

4.7 ALUMINIUM & STAINLESS STEEL SURFACES All aluminium and stainless steel surfaces that are to be coated shall be cleaned in accordance with Section 4.2. Stainless steel surfaces are to be additionally abraded or sweep blasted using non-metallic abrasive to provide an effective keying surface. Any coating to be applied directly only stainless steel shall contain no more than 50 ppmv of leachable chlorides.

4.8 CONCRETE SURFACES Concrete surfaces to be coated shall be prepared in accordance with NACE RP 0892 and the coating manufacturer’s recommendations to ensure a suitable surface for over coating. Concrete cure shall be confirmed by an acceptable method (e.g. AS1012 Method of Testing Concrete). All concrete defects (e.g. honeycombs and spalling), laitance, physical damage, chemical damage and contamination shall be repaired/rectified using a method approved by the principal. Guidance can be found in NACE No 6/SSPC-SP13.




Surface preparation shall be in accordance with the most appropriate of the methods laid out in NACE No 6/SSPC-SP13. The proposed method shall be submitted to the Principal for acceptance, if accepted, a written acceptance will be issued to the Contractor. Acceptance criteria shall be as for severe service (significant exposure to traffic, chemicals and/or changes in temperature) as detailed in Table 1 NACE No.6/SSPC SP13 and reproduced below. Table 4.2: Acceptance Criteria for Concrete Surfaces after Surface Preparation

5 COATING APPLICATION 5.1 INTRODUCTION

The coating systems to be applied shall be as detailed in Section 8 & 9. It should be noted that both 'New Construction' and 'Maintenance' sections are included for most systems. Woodside approved coating materials are nominated in the coating system detail in Section 10. It is the project engineer’s responsibility in consultation with the TA to ensure that the coating systems selected from section 10 will meet the required operating conditions for the stated design life. The coating contractor in accordance with the Woodside deviations process may submit alternative products to those nominated in Section 10. This must receive package engineer (in consultation with Woodside TA or Woodside TA if maintenance work) approval prior to application and may include low temperature cure rapid recoat coatings where appropriate. Paints containing metallic zinc shall never be used on, oversprayed or dropped onto stainless steel pressure retaining components. Polysiloxane gloss topcoats may be a suitable alternative to the urethanes and acrylics that Woodside have extensive experience with for large static surfaces with little risk of impact damage. The use of Polysiloxane coatings may be submitted through the Woodside deviation process on a case by case basis where there is a suitable business case including extensive technical information to justify their use. The colour of the final coat shall be as nominated in Section 11 for offshore structures, vessels and equipment. Offshore pipework colour coding shall also be in accordance with Section 11. Onshore colour codes are presented in Section 12. Colours listed as “Practical Equivalents” to those in accordance with AS 2700 shall be acceptable. Pipe insulation cladding shall be left unpainted unless otherwise specified. Surfaces requiring temporary protection shall first be cleaned in accordance with Section 4.2 and then protected either by application of Shell Ensis Fluid SDC or equivalent for periods up to 6 months indoors, (1 month outdoors), or Shell Ensis Fluid HB or equivalent for periods up to 12 months indoors, (6 months outdoors).

5.2 APPLICATION - PROCEDURES CONSTRAINTS AND QUALITY CONTROL The paint manufacturer’s product data sheets and specifications for mixing, application and curing shall be considered an integral part of this standard. The Contractor shall be responsible for obtaining from the paint manufacturer or supplier the product and safety data sheets of each material. All coating systems shall be applied in accordance with this standard and the paint manufacturer's instructions and data sheets. Any conflicting requirements shall be brought to the attention of the Principal prior to the application of the coating. Coatings shall be free of dust, dry spray, oil, entrapped grit, grease and other contaminants before application of succeeding coats.




Coating application shall begin as soon as surfaces are prepared, inspected, and before surface deterioration occurs. Zinc rich primers shall be applied over abrasive blast cleaned carbon and low alloy steel surfaces only. Paints containing metallic zinc shall never be used, over sprayed or dropped on stainless steel pressure retaining components. To ensure that only correctly blasted surfaces are coated, a minimum of 100 mm around the edges of prepared areas shall be left uncoated, unless adjoining a coated surface. When adjoining a coated surface, the connection to the existing paint film shall be made as described in this section. In case an object is delivered by the Principal to the Contractor in order to be painted, the Principal shall inform the Contractor about the layers of coating which have already been applied and the Contractor shall complete the required system in accordance with this standard. No coating shall be applied within 50 mm to areas that need to be welded later. Crevices or pits that cannot be adequately coated shall, after blasting operations and prior to application of the final coating, be sealed with an approved caulking compound. Excess caulking compound shall be removed. Caulking compound must be approved in writing by the manufacturer of the coating material being applied and by the Principal. For quality assurance and control refer to Section 6.

5.2.1 Ambient Conditions Coatings shall not be applied:

• When surface temperatures are less than 3º C above the dew-point temperature of ambient air.

• During exposure to inclement weather conditions (e.g., fog, mist or rain).

• When relative humidity exceeds 85%.

• When the ambient temperature is below 10° C for zinc/epoxy/urethane systems. Note: Low temperature coatings may be allowed. Contractor shall submit proposed coatings for low temperature application to Principal for written approval prior to use.

• When other detrimental conditions exist (e.g., high winds or airborne dust). High winds shall be defined as winds in excess of 25 kilometres per hour (13.5 knots).

• If the coating manufacturer’s recommendations for temperature and humidity limitations differ from the above, written approval to proceed must be submitted from manufacturer.

• Contractor shall ensure adequate ventilation and airflow in all recesses of enclosed areas to allow removal of solvents and proper cure.




5.2.2 Mixing and Thinning The mixer and pot shall be thoroughly cleaned before mixing of new materials. All coating materials shall be mixed and thoroughly stirred in accordance with the instructions of the paint manufacturer. Sufficient agitation to maintain good mixing shall be applied until the product is used. If during mixing/stirring air is entrapped in the product, sufficient time should be allowed for air bubbles to escape before application. Only thinners as specified by the paint manufacturer shall be used. When the manufacturer’s specified pot life is reached or other indications of elapsed pot life such as thickening or film-build problems occur, the material shall be discarded. The paint manufacturer shall specify the type and amount of thinners that can be used and the contractor shall maintain an accurate record of the amount of thinner used.

5.2.3 Compatibility With Existing Coating Systems Before commencing any painting work, the compatibility with existing coating systems or layers shall be checked. The paint manufacturer shall be consulted. If there is any doubt about compatibility, the patch test in accordance with ASTM D 5064 shall be conducted to evaluate the interfacial adhesion. Coating layers should be over coated only with products made by the same manufacturer.

5.2.4 Over Coating Coatings shall be dried and cured in accordance with paint manufacturer’s recommendations, prior to over coating. Before over coating, over-runs, droppings and smears shall be removed and any coating damage or imperfection shall be repaired. Where the DFT does not meet the requirements of this Standard, corrective action shall be taken. When a zinc primer is specified in coating systems, these shall be over coated as soon as possible but only after sufficient cure if the primer is an inorganic zinc primer. The paint manufacturer’s maximum over coating times shall not be exceeded. Zinc salts that have formed during the intervening period shall be removed in accordance with the paint manufacturer's instructions prior to over coating.

5.2.5 Handling Very few of the coating systems in this standard will take rough handling or impact with a sharp object. The bulk of external corrosion on WEL assets is due to mechanical damage to coatings. After proper application of the coatings, components must be handled with due diligence.




5.3 APPLICATION METHODS Airless or pneumatic spray applications are the preferred methods of application. If spray painting is to be carried out, the following shall be taken into account:

• Spray painting may cause interference with other works and so approval from Woodside shall be obtained.

• The correct spray tips, air pressures etc, as recommended by the equipment supplier, shall be used.

• Spray guns shall be held perpendicular to the surface and at a distance required to deposit a continuous wet layer of coating. Arcing of the gun shall not be permitted.

• Conventional spray guns shall be held 150 to 300 mm from the surface. Airless spray guns shall be held at a distance such that the fan width does not exceed 300 mm.

• Each spray pass shall overlap the preceding pass by 50%. Visible streaking at the overlap shall not be acceptable. Large areas being coated with high build materials (nominal dry film thickness above 100 microns) shall receive passes in two (2) perpendicular directions.

Each coat shall be applied uniformly and completely over the entire surface. All runs and sags shall be brushed out immediately or the paint shall be removed and the surface resprayed. Brush application may be used under the following circumstances:

• When spraying for any reason, such as complex geometry, material or environmental considerations cannot properly coat areas.

• For the initial stripe coat of paint to all corners, edges, crevices, holes, welds or irregular surfaces prior to spray application.

• For “touch up" or repairs to localised damaged paint or areas of incorrectly applied paint.

Brushes shall be of a style and quality that will permit the proper application of paint. Brush applications should be done in two passes that are at right angles to each other so that a smooth coat, as near uniform in thickness as possible, is obtained. There should be no deep or detrimental brush marks. Paint shall be worked into all crevices and corners. Runs and sags shall be brushed out. During the application of each coat, all areas such as corners, edges, welds, small brackets, bolts, nuts, and interstices shall receive additional paint to ensure that these areas have at least the minimum specified dry film thickness and to ensure continuity of coating. Stripe coating shall provide a continuous coating film and shall not exceed the maximum dry film thickness specified for that material and shall be touch dry before over coating.




5.3.1 Repair/Reinstatement 5.3.1.1 Organic & Inorganic Coatings

Small areas of coatings, which require repair may be abraded to bare steel with sandpaper, hand file or rotating fibre discs. Coating materials may be applied to such repair areas using a brush. Coatings, not including inorganic zinc, which have to be over-coated and which have become contaminated with oil, grease, or other foreign material shall be cleaned with water soluble biodegradable cleaners and then water rinsed. Inorganic zinc primers lightly contaminated with oil, grease, or other foreign material shall have the contaminants removed using a biodegradable hot water detergent pressure wash. Heavily contaminated inorganic zinc silicate shall be removed and reinstated. Inorganic zinc surfaces must be thoroughly dry prior to over-coating, preferably by constant flow of dry ventilation over the surface for a minimum of four (4) hours after washing and before over-coating. The repair technique for coatings with dry film thickness below that specified shall depend upon the state of cure of the coating. Coatings that have exceeded the minimum recoat interval and have not exceeded the maximum recoat interval may be cleaned, as required, and over-coated with the same material. Coatings that have exceeded the maximum recoat interval shall be removed by blasting or at the discretion of the Principal quality control representative abrading the surface to provide an adequate key for overcoating. Principal will not accept additional costs for repair work. Inorganic zinc silicate (IZS) primer with dry film thickness (DFT) above that specified (as measured in accordance with AS 3894.3 Method B) shall be removed by blasting. For IZS coatings with DFT less than that specified but beyond the recoat interval may be overcoated with a compatible zinc rich epoxy to achieve the required DFT. The application of IZS coatings in humidities of < 50% shall require the use of either a water mist or wet hession covering the IZS coating within 1 hour of application but after the coating has dried sufficiently to be water insoluble to ensure full cure of the coating. Runs and sags shall be brushed out immediately or the coating shall be removed. When welding occurs after coating application, the coating shall be removed by spot-blasting 100 mm past the edge of the heat-affected coating. After welding, the surface shall be prepared in accordance with this standard and the paint shall be reinstated such that the finished coating complies with this standard. Coating defects or damage shall be reinstated such that the finished coating complies with this standard. All repair and reinstatement procedures shall be submitted to Woodside for approval, prior to commencement of the repair. The procedures shall take into consideration all surface preparation requirements to ensure that full substrate and inter-coat adhesion is achieved. Touch up of the zinc primer (inorganic zinc silicate or hot dipped galvanised) shall be with a zinc rich epoxy complying with AS3750 Part 9 Type 2.




All care shall be taken during the lifting, tie down and transport of coated items, to minimise damage. Repair of coating damage, occurring as a result of transport by the Contractor, shall be the responsibility of the Contractor.

5.3.1.2 Thermally Sprayed Aluminium Surfaces Areas of insufficient thickness of thermally sprayed aluminium (TSA) shall be rectified by further application of TSA, and before the seal coating application. Areas of damage or defective coating including sites of adhesion testing and areas of coating which fail to meet the requirements for adhesion shall be repaired as follows:

• Seal coat shall be removed by blast cleaning

• Damaged or defective TSA coating shall be removed by abrasive blasting

• Repair area shall be prepared by blast cleaning to AS 1627.4 class 2.5/ 3

• Small points of damage or defective coating shall be prepared for recoating by vacuum-blasting or power disking, subject to acceptance by Principal, if necessary to avoid damaging surrounding sound coating

• A 75mm margin of sound coating shall be feathered to a fine edge by vacuum blasting.

• TSA coating shall be re-instated in accordance with this standard.

5.4 COATING OF FLANGE BOLTS AND NUTS The back face of carbon steel flanges shall be primed only prior to assembly. Following assembly, the remainder of the system can be applied to the joint including the bolting. Stainless steel bolting should be left unpainted. Carbon steel bolting that requires tensioning with Hydro-tight equipment (studs over 1 3/8”) should be blasted and wrapped in Denso tape for preservation. Destec Hub identification markings should be masked and that area be top coated with urethane for easy viewing. Galvanised structural bolts should be treated with the same system as the structure.

6.2 SURFACE PREPARATION INSPECTION 6.2.1 Surface Profile

The surface profile shall be assessed by profile comparator standards in accordance with AS 3894.5 Method B. This shall be confirmed by other techniques (such as a calibrated depth micrometer or replica tape. This assessment shall be carried out at random locations over the prepared surface to provide an accurate assessment of the surface profile. The number and locations of determinations shall be as described in Table 6.2. Surface profile results shall be included in the Contractor's Coating Inspection Report if applicable to the specifications.

6.2.2 Surface Cleanliness Surface cleanliness shall be determined just prior to coating application by comparison to ISO 8501 or approved equivalent visual standards. Adequate light (500 Lux) shall be present for colour discrimination. For surfaces to be coated with TSA, residual surface dust levels shall be checked using the procedure detailed in ISO 8502-3 (Pressure sensitive tape method) with an acceptance criteria of 2 or less as per Figure 1 of that standard. Surfaces that fail the acceptance criteria shall be further cleaned of dust using clean, oil free dry air or industrial vacuum cleaner. The tapes for the final cleanliness achieved shall be included in the daily reports.

6.2.3 Ambient Conditions Prior to commencement of any coating application, the component temperature, ambient temperature, dew point and relative humidity shall be measured and recorded on the Contractor's Coating Inspection Report. A psychrometer shall be used at the location to determine the relative humidity.

6.3 COATING APPLICATION INSPECTION & TESTING 6.3.1 Dew Point, Air Humidity and Substrate Temperature

No coating work shall be carried out when the temperature of the surfaces is less than 3°C above dew point or the relative humidity of the air is greater than 85 % and the air or substrate temperature is below 10°C. For maintenance painting offshore a maximum relative humidity of the air of 90% is acceptable. Dew point determination shall be done in accordance with ISO 8502-4. No coatings shall be applied to surfaces exceeding a substrate temperature of 50°C. Higher substrate temperatures shall only be accepted if paint manufacturers have confirmed in writing that this application shall not affect the quality of the coating work.

6.3.2 General Coating Appearance The completed coating shall be free from defects such as runs, sags, pinholes, voids, bubbles, orange peel, grit, dust inclusions or other deleterious anomalies and be of good visual appearance. The topcoat shall completely cover the colour of the underlying layers.




6.3.3 Wet Film Thickness (WFT) Spot checks shall be carried out during the course of painting operation to ensure that film thickness is being maintained. These shall be performed according to the procedure described in AS 3894.3 Appendix C – WFT by comb gauge.

6.3.4 Dry Film Thickness (DFT) Coating dry film thickness (DFT) measurement method shall be in accordance with AS 3894.3 method B(Magnetic induction and Eddy current methods) or the equivalent SSPC PA2. For measurement of dry film thickness, the digital magnetic induction type gauges are preferred for magnetic substrates and the eddy current type gauges for non-magnetic substrates. The magnetic ‘banana’ type gauges shall not be used. DFT gauges shall be calibrated daily or when dropped or when subjected to extremes of heat and/or cold. The number of measurements shall be in accordance with Table 6.2 or SSPC SP2. Calibration shall be done in accordance with AS 3894.3 appendix D or SSPC SP2. For the acceptance of an inspected area the following criteria shall be fulfilled:

• The dry film thickness of the completed coating system shall be equal to or greater than the specified minimum end of the range of dry film thicknesses as detailed in section 8 & 9;

• The average of the dry film thickness of the individual coating layers shall be equal to or above the specified minimum dry film thickness in the range. No single spot measurement shall be less than 80% of the specified minimum thickness. For TSA a single minimum value of 180 microns shall be acceptable.

• The dry film thickness of the individual coating layers shall be maximum 1.2 x the maximum DFT shown in the range, except for areas such as corners where overlaps are difficult to avoid. For such areas a maximum of 1.5 x the maximum DFT shall be accepted.

Note 1: Where specified all piping and vessels, excluding uncoated stainless steel, should have an off-white (BS 5252 00A05, AS 2700 – Y35) continuous topcoat. The service shall be indicated by colour banding (must be colour stable) applied to the final painted surface. The colours for each service are indicated in the preceding table. Colour banding may be by painting or durable tape material. Direction of flow arrows shall also be applied to the final painted surface. For insulated lines, the identification and direction of flow arrows shall be applied to the outer surface of the insulation cladding. (N.B. Tape materials may not be suitable for harsh NW environment and may produce crevices).

Each colour band shall be approximately 150mm wide. Where two colour bands are required to indicate a service, a 400mm band of the first listed colour shall be applied with a secondary colour placed in the centre of the base colour band. Banding shall be applied at bulkheads, package and vessel termination points, pipe junctions and either side of each valve

Note 2: With prior approval from Woodside, small integrated packages (eg fire pumps/motors may be painted the colour of service).
