6.1 Preliminary Works

6.1.1 Prior to commencement of any blasting work on either new or previously painted

surfaces all Greases, oils, and dirt’s and any other contamination shall be removed in accordance with the requirements of SSPC-SP 1. Any or all of the following methods may be used :

a. Steam cleaning with or without Alkaline cleaners. b. High pressure fresh water wash with or without emulsifying agent.

Any emulsifying agents or chemical products utilised for degreasing and cleaning works shall be materials registered or approved by the UK, Dept. of Trade and Industry Offshore Chemical Notification Scheme. The registered category (1,2,3,4,5) shall given the maximum allowable open disposal limit over the contract scope of work. On completion of the degreasing/cleaning, all surfaces shall be high pressure fresh water washed (3000 psi)

6.1.2 The surface shall be allowed to dry before proceeding with further preparation and/or

painting.

6.1.3 Following washing down, the chloride level on the washed surface immediately prior to paint applications shall be only 0.7 µg/cm2 (microgram per square centimeter) above that value of the fresh wash water when measured with a Salt Contamination Meter approved by ADMA-OPCO. However, in no circumstances shall this value exceed 1.8 µg/cm2. Repeated highpressure wash down is required until the desired salt level is obtained. If the supply of fresh wash water salt level is above 1.1 µg/cm2 the water shall not be used and must be rejected. ISO 8502 – 6 may also be used to determine critical levels.

6.1.4 Washing down using airless spray equipment is not an acceptable alternative to high

pressure water jetting. 6.1.5 All weld areas and appurtenances are to be given special attention to remove surface

irregularities including weld spatter, weld fluxes, rough capping, undercut and slag prior to commencement of abrasive blasting.

6.1.6 Surface laminations, underlying mill scale and laps not removed during fabrication

shall be removed and made smooth by grinding using mechanical power tools. Also all sharp and rough edges shall be smoothed or radiused to 2 mm contour.





6.1.7 All irregularities which become apparent after surface preparation by abrasive

blasting/cleaning shall be similarly treated as described in Clause 6.1.5 to 6.1.6 above. 6.1.8 All the works referred to in Clause 6.1.5 through 6.1.7 above shall be carried out under

close supervision of ADMA-OPCO Inspection Authority.

6.2.1 General

a. Abrasive blasting operations, ventilation and safety requirements shall be in accordance with ANSI Z9.1.

b. When specified, surface preparation by abrasive blasting or power/hand tools

shall not be conducted when the temperature of the surface is less than 3oC (5oF) above the ambient dew point of the surrounding air and/or when the relative humidity of the air is greater than 85 %.

6.2.2 Surface Quality

a. Steel surfaces shall be prepared by abrasive blasting to ISO 8501-1 and

reference shall be made to the contained photographic illustrations to ensure the specified standard is met. The grade of surface finish or deviances from this situation will be dictated in the relevant paint specification.

b. In circumstances where abrasive blasting cannot be carried out, surface preparation shall be conducted by mechanical means to obtain a surface quality equivalent to St3 of ISO 8501-1 following ADMA-OPCO approval. Where an alternative paint system is required to suit such quality of surface preparation, relevant details will be provided by ADMA-OPCO, on request.





6.2.3 Abrasive Materials

a. The Contractor shall carry out all the necessary tests, inspection and

experimental trials to ensure that the abrasive materials fully meet the Manufacturer Specification and ADMA-OPCO requirements stipulated herein.

b. If however, the abrasive materials supplied by the Contractor are unable to

14.1.3 Individual characteristics of different services within the common group are

distinguished by a secondary Colour. 14.1.4 Any pipework originally painted (background Colour coded) along its entire length

with one of the basic Colours, an aluminum contrast band shall be used as an additional outer most Colour to distinguish between the decorative Colour and the basic Colour identification of this particular pipework.

14.2 Application of the Pipeline Identification Colours

14.2.1 Colour Identification Band Lay-out

The Colour identifying all pipeline contents within ADMA-OPCO facilities are listed in Appendix-B. The Colour coding shall consist of three bands, the outside Colour bands shall be the basic identification Colour for a particular family of commodity, and the central band shall represent the secondary Colour allocated for characterizing further the type of fluid within this major family or group (See Appendix-C Fig. 1)

14.2.2 Contrasting Bands

The protective or background Colour code of the pipe shall not account for the basic identification Colours. If the decorative Colour interacts with the basic Colour, a strip of aluminum band (50 mm) wide shall be applied at the outer edges of the basic Colours (See Appendix- C Fig. 2).

14.2.3 Surface Preparation

Prior to the application of Colour identification bands, directional flow arrows, contrasting band and line numbers, all surfaces must be degreased, detergent washed with 5% biprox or equivalent, high pressure fresh water washed and allowed to dry. Section 6 of this Manual shall be followed to satisfy the preliminary work requirements. It may be necessary to slightly abrade the surface using fire emery paper prior to the application of the identification Colours.





14.2.4 Marking Lines in Close Proximity

In instances where a run of multiple lines exist e.g. pipe racks or major pipe supports, the Colour identification, flow direction arrows and line numbers shall be positioned directly in line with one another on individual pipes and shall be easily visible.

14.2.5 Safety Related Pipework

Pipework related to safety, such as fire protection, firewater, foam piping, etc. when specified for Colour coding should be entirely coated from origin to all extremities in Red (04 E 53).

14.3 Materials

The application of the Colour identification shall be employed using approved Polyurethane paint applied over a contrasting high build undercoat matching British Colour Standard BS 4800. The former materials shall be chosen from ADMA-OPCO Approved Paint products.
