(Ref. 32). Higher substrate temperatures shall only be accepted if the

Manufacturer has confirmed in writing that this application will not affect the

performance of the coating work.

8.7 Holding Primers

A holding or temporary protective primer may be applied to prepared metal

surfaces to facilitate shop or site handling procedures. Such primers shall in no

way replace the function or film thickness of any part of the specified coating

system. Overcoating of zinc epoxy or acrylic based holding primers will not be

permitted by the COMPANY. These primers shall be completely removed by blast

cleaning prior to application of specified primer / first coat. Sweep blasting of

inorganic zinc shop primers may be allowed where CONTRACTOR can

demonstrate to COMPANY'S satisfaction, by submission of supporting test data

based on long term cyclic testing, that there is no reduction in system adhesion

or performance. CONTRACTOR shall also demonstrate that sufficient controls

are in place to ensure adequate cleanliness and condition of the aged primer

before overcoating.

Alternative surface cleaning is only acceptable after written approval of the

COMPANY.

In all cases, areas of localised breakdown, and weld areas or damaged areas

shall be cleaned to the full specified standard.

In areas where cathodic protection will be applied, the full coating system

including the holding primer shall be tested for cathodic disbondment in

accordance with ASTM G8 (Ref. 8) or ASTM G42 (Ref. 9).

8.8 Coating thickness

The coating systems are detailed in Annex A "Coating Systems Summary Sheets"

and the nominal dry film thickness (DFT) is given for each coat. The DFT of any

coat shall not be greater than 40 % above nor 10 % below the nominal value

specified. The exception to this is for Thermally Sprayed Aluminium (TSA) where

the minimum overall thickness shall be 200 μm. The DFT shall be measured in

accordance with SSPC-PA 2 (Ref. 33).

The minimum dry film thickness (MDFT) is the acceptance thickness for the total

applied coating system, based on a 95 % probability of this value being exceeded

by any individual measurement. In practice, this requires statistical records to

be maintained of thickness measurements.

Spot checks shall be carried out during the course of the painting operation to

ensure that film wet film thickness (WFT) is being maintained. These shall be

performed according to the procedure described in ISO 2808, Method No. 1A -

comb gauge (Ref. 34).

8.9 Multi coat systems

Sequential coats shall be contrasting colours so that each stage of the work can

be readily identified and their film thickness determined.

Intervals between coats shall be kept to the minimum complying with the

coating SUPPLIER’s recommendations at the prevailing temperature in order to

avoid contamination between coats. Any contamination between coats shall be

removed.

Zinc silicate and zinc rich epoxy primers shall be tie-coated or over-coated

within a maximum of seven (7) days unless specific approval has been given by

the COMPANY to extend this period.

In the event of specified maximum recoating intervals being exceeded, or for

the application of additional coats to existing weathered coatings, the COMPANY

shall be informed and the Manufacturer’s recommendations for surface

preparation shall be fully described. This may involve sweep blasting, or water

or solvent washing before top coating or such other measure as approved by the

COMPANY.

8.10 Weld areas

No coating, except "weldable" grades of zinc based holding primers, shall be

applied within a minimum of 50 mm or edges / areas prepared for welding. The

zinc based holding primer shall be a grade which is approved by a certifying

authority such as Lloyds Register or equivalent as not being detrimental to the

resultant weld.

The following procedure shall be followed with regard to welding, where zinc

silicate or zinc rich epoxy and tie coat are used:

Intended weld area shall be masked after blast cleaning and before priming,

as stated in Section 6.6;

After the application and curing of the primer, an additional 50 mm on each

side of the primed surface, immediately adjoining the weld area, shall be

masked. The tie coat shall be applied within the stipulated 7 days;

When ready to weld, the first tape shall be removed from the base steel

exposing the weld area;

On completion of welding, the area shall be mechanically cleaned to

remove weld contamination and debris; thereafter the remaining masking

tape shall be removed and the weld area pencil blasted, extending this to

sweep blast the 50 mm of primed surface before proceeding with priming

and coating;

Any masking tape used shall be removed as soon as possible to avoid damage

to the surface underneath.

8.11 Carbon/stainless steel joints

Where carbon steel is welded to stainless steel, the joint shall be coated with

the coating system specified for the stainless steel with a minimum overlap of

50 mm onto the carbon steel. However, the nominal dry film thickness (NDFT)

requirements for the connected carbon steel shall be applicable.

8.12 Protection of applied coatings

Applied coatings shall be adequately protected and the temperature and

humidity controlled in accordance with Manufacturer’s recommendations to

ensure that all coatings are correctly dried and cured.

8.13 Protection of coated contact points

At contact points such as where piping rests directly on a support (e.g. a saddle

or beam), there is a potential for severe corrosion. Therefore coated surfaces

which will be in contact with other surfaces shall be protected with non-

metallic inserts or shims such as Teflon straps or preformed self-adhesive shims,

usually made from fibre reinforced plastic.

Shims should have a limited contact area and high impact strength, and retain

their properties over sustained load and offshore exposure conditions. A

corrosion resistant U-bolt coated with a protective non-metallic material should

complete the pipe clamps.

Where clamps are not used, shims made from creep resistant plastic materials

such as acrylonitrile butadiene styrene (ABS) are available. These can be

adhesive bonded to the underside of the pipe.

The selected system for protection shall be agreed with the COMPANY. Such

protection shall be applied when coatings are fully cured.

9 REPAIRS

9.1 General

Repair of defective areas shall be accomplished in the same manner as the

original coating in regard to surface preparation prior to recoating, unless

alternative and equivalent methods are defined within this specification, or

agreed by the COMPANY.

Epoxy coatings which have aged to the point where further application may give

rise to intercoat adhesion problems, shall be sweep blasted after cleaning prior

to further coating. Approval for this work shall be obtained from the COMPANY.

9.2 Insufficient Thickness

In the event that a completely coated surface is found to have insufficient

coating thickness, this surface may, subject to specific COMPANY approval,

receive an additional coat or coats until the specific thickness is achieved. The

COMPANY may alternatively require the surface to be blast cleaned and

recoated. Surfaces to receive additional coating shall be properly cleaned of all

foreign matter or contaminants and prepared as recommended by the

Manufacturer.

9.3 Excess Thickness

In the event that a coated surface is found to have excessive thickness, it shall

be brought to COMPANY's attention who will decide on the appropriate action to

be taken. Acceptance by COMPANY of excessive thickness will be considered

only if the measured thickness is confirmed by the Manufacturer in writing as

not being detrimental to the satisfactory service life and performance of the

coating system and if testing demonstrates that there is no loss in system or

intercoat adhesion.

9.4 Film Defects

Defects such as misses, incorrect colour, gloss level and poor hiding power shall

be repaired by applying additional coating as required.

Defects such as poor finish, texture, sagging, runs, dry spray and over-spray

shall be removed by abrading the film to remove the defect and then applying

additional coating as required.

Defects such as poor adhesion, pinholes, holidays and cracking shall be

completely removed by blast cleaning to substrate and reapplying the complete

system.

Damaged areas, defects in the coating system such as over-runs, drips and

smears that have to be removed or areas with inadequate DFT shall be re-

cleaned. The re-cleaning shall carry over on to the secure surrounding coating

for not less than 250 mm all round and the edges shall be feathered (over a

width of at least 70 mm). After surface cleaning the specified coating system or

the required layers of the specified coating shall be re-applied. Any additional

coats shall blend in with the final coating on adjoining areas. Manufacturers

shall be consulted if the existing coating requires abrading before over-coating

to obtain good bonding.

9.5 Repairs To Zinc Coated Surfaces

Where repairs are required to zinc rich epoxy primer or galvanized surfaces,

either with or without topcoats, the following procedure shall be followed:

Blast clean surface using grit to preparation grade Sa 2½ in accordance with

ISO 8504-2 (Ref. 11);

Apply 70 µm DFT zinc-rich two-pack epoxy primer in two coats;

Apply topcoats as required to achieve original system thickness.

Overcoating may be permitted before complete curing of the zinc rich epoxy

provided that all volatile material has evaporated.

It shall be noted that the above procedure is for repairs only. Under no

circumstances shall this procedure be used in place of original priming to

specification or galvanized surfaces.

Surface preparation by any other method than blast cleaning shall only be

permitted with the written approval of the COMPANY.

COMPANY may require that CONTRACTOR completely removes and re-apply the

full coating system where the extent of repairs is considered to be excessive.

Inorganic zinc silicate shall not be overcoated by itself. Insufficient coating

thickness shall be reblasted and recoated.

Repair to damaged galvanizing when the extent of damage exceeds 40 mm2,

shall be subject to COMPANY approval.

9.6 Coating Under Intumescent Fireproofing

All coating which is applied under fireproofing shall be approved by the

intumescent fireproofing material SUPPLIER prior to application.

All steel to be fireproofed, plus a continuous band of steel of minimum width

300 mm away from it, shall be primed and over-coated with a system which has
