5.6 Flammable Atmospheres (Area Classification)

The Client will advise area classifications for both plant design and construction/ maintenance periods. Some classification may preclude use of certain paint compositions.

The classification for construction or maintenance periods will affect the minimum rating permissible for the Contractor's electrical equipment.

The Contractor shall provide all necessary data for the proposed paint systems and solvents in order to permit area classifications to be determined for the duration of the painting works.

5.7 Precautions in Cleaning and Application of Paints

Specific precautions shall be taken to avoid the build-up of flammable atmospheres from cleaning solvents or paints in confined spaces. These shall include attention to weather protection, ventilation and type of lighting used.

Work shall be carried out to company and client procedures and take account of all applicable HSE regulations and statutory requirements.

5.8 Personnel/ Items to be provided by the Contractor

The Contractor shall supply all necessary personnel, equipment, painting, inspection and recording instruments, including (unless specified otherwise) the following:

-• Evaluation of all hazards and provision of proposals to meet HSE requirements; • Skilled, experienced and competent personnel/ supervision (taking account of work

scheduling, transportation and accommodation requirements);

• Product data and materials safety data sheets, including valid COSHH assessment; • Provision and maintenance of plant, equipment and tools including those listed below; • Scaffolding, staging, cradles, etc.;

• Surface preparation equipment; grinders, blasting equipment, vacuum cleaners etc.; • Paint and thinners;

• Paint mixing equipment, spraying equipment (including air compressors and generators) rollers, brushes solvents and clean rags.

(8)

6.0 PREPARATION FOR COATING

Prior to commencing any coating application surfaces shall be free of irregularities, millscale and rust and surface contaminants.

6.1 Surface Irregularities

Surface irregularities shall be removed/ made smooth prior to surface preparation. Irregularities include:

-• Sharp or rough edges and burrs; • Surface laminations and laps; • Weld spatter, and slag.

Such irregularities, which appear after surface preparation by blast cleaning, shall be similarly treated. If grinding is necessary it shall be subject to AMEC approval and checking of remaining wall thickness.

6.2 Surface Contaminants

Steel that has been exposed to a salt laden atmosphere shall be tested for the presence of salts using the potassium ferricyanide test in accordance with BS 5493 Appendix G. Salts shall be removed by washing.

Cleaning to remove oil and grease shall be carried out using proprietary emulsifying agents and then washing with clean water. The surface shall be allowed to dry before proceeding with further preparation and painting.

6.3 Blast Cleaning

Open dry grit blasting is required in general for new construction.

Open dry grit blasting is not acceptable to Maintenance Operations as it produces large amounts of dust and grit, which contaminate a large area surrounding the location where grit blasting is being used. This can be controlled by use of the Vacublast system.

Although, power tool cleaning may be more suitable in certain areas, it produces a poorly prepared surface, hence the coating applied over it can be expected to fail in 18 months to 3 years.

The surface preparation method to be used for maintenance coating is precision wet abrasive blasting. The advantages of wet abrasive blasting are as follows:

• Removes most surface contaminates including millscale and profiles the steel surface; • Other trades can work safely in close proximity;

• Virtually dust free; • Environmentally friendly;

• Intrinsically safe and can be used in Zone 1 and 2 locations; • Extended coating life expectancy.

Disadvantages of wet abrasive blasting are as follows: • Grit and water are used, though low quantities of each;

• Grit has to be removed from site to avoid blocking open drains;

• Sheeting and light enclosures are necessary to prevent slight grit spread;

• Confined spaces and overhead working are difficult due to splash-back effect and poor operation visibility.

(9)

7.0 SELECTION OF COATING MATERIAL SUPPLIER

Materials for coatings shall be selected based on the following: • Prior long-term good experience;

• Compliance with Health and Safety criteria specific to the location and Platform; • Qualification to NORSOK M-501;

Spools are to be designed to contain no more than one bend/ elbow.

Internal flange weld roots must be ground flush and the flange/ bore edge radiused to 5.0 mm (equal to the rubber coating thickness).

Spool dimensions must be adjusted to allow for 5.0 mm thick ebonite rubber to be applied to flange faces. Seawater - 5.0 mm thick neoprene, Shore A Hardness 65 ± 5.

Produced Water - 5.0 mm thick abrasion resistant natural rubber, Shore A Hardness 45 ± 5. Maximum operating temperature of this rubber is 85°C. Higher operating temperatures necessitate use of neoprene which does not have such good abrasion resistance.

Flange faces shall be lined with ebonite with a thickness of 5 mm and Shore D Hardness 70 ± 5 This is relatively incompressible and still requires that a suitable flat rubber gasket is used for rubber lined flange faces. All rubber coatings shall be cured by applying the vulcanising process in a steam autoclave.

12.0 COLOUR SCHEDULE 12.1 General

Unless stated otherwise, British Standard colours referred to are to BS 4800-1989.

All equipment, pipework, valves flanges and fittings are to be painted throughout the entire length, including in flange bolt holes in accordance with ground colour specified.

Working pressures and arrows indicating direction of flow should be shown on ground colour, preferably in black (or white where contrast is required) near to junctions, valves and vessels.

12.2 Pipework Identification

Colour banding maybe by painting or by using a durable adhesive PVC tape, which must be suitable for external weathering. The tape should be applied in accordance with manufacturer’s instructions. Banding shall be applied at:

• Bulkheads, deck and other penetrations, major changes of direction • Package and vessel termination points, pipe junctions

• Positions such that banding sets are normally visible and no greater than 7m apart.

The primary colour (outside) banding shall be placed directly adjacent to and on each side of, the secondary colour (inside) band. Width of bands shall be 150mm. A flow direction arrow in black shall be located on the pipe downstream of the colour bands on pipe-work. Arrows shall be 150 - 200 mm long x 25mm wide at the base of the band head and at the tail.

Stainless steel pipework and pipework coated with thermal spray aluminium shall have service indicated by colour banding alone, unless otherwise specified.

Insulated piping shall have service indicated by colour banding alone over the cladding.

Colour banding shall be in accordance with the following table and if required with BS 1710:1984 and amendment No 1-1989.

12.3 Piping System Colour Schedule

Piping shall be painted white in accordance with BS4800 00E55. For corrosion resistant alloys where protective coating is not required, and for thermally sprayed aluminium surfaces, the material shall be left self-coloured. All piping shall be identified by service using colour bands in accordance with table 1. These colours shall normally be applied by coloured adhesive plastic tape markings rather than by painting, and such markings shall as a minimum be placed at all bulkhead and deck penetrations, either side of every valve, at each tee or branch connection. In order to avoid any requirement for separate marking of flow direction with arrows and for individual service names, the colour marking tapes may incorporate flow arrows and service names if desired.
