FAC-2009-CW690260


C0109 WAV


Rev. No.: B



3.1 Painting Qualification Test

Prior to mobilization and commencement of all project painting operation, the painting qualification

test will be carried out which will include surface preparation, mixing, application and inspection.

This will be done in the presence of designated COMPANY representative on site.

All surface preparation and painting test will be made under simulated site condition if done in the

workshop environment. All inspection such as visual examination, cleanliness and film thickness

tests shall be performed strictly to the COMPANYs specification.

3.2 Accepted Brand

Only specified painting system from painting system data sheets shall be used, unless alternates

are reviewed by CONTRACTOR and COMPANY duly notified in writing.

The CONTRACTOR shall only use paints which comply with Federal, State and Local air pollution

regulation

The Iamsub paint which is the COMPANY approved alternate coating system for the riser flange

weld area shall be applied as per manufacturer specifications whenever it is used.

The latest issue of the paint manufacturers product data sheets, application instructions and

Material Safety data sheets shall be available at the painting site and complied with during paintingoperations.

3.3 Material Storage and Handling

Painting materials shall be stored and handled in accordance with the manufacturers instructions

Materials shall be delivered to the place of application in unopened, original containers bearing a

legible product designation, batch number, expiry date, shelf life, date of manufacture and colour

codes applicable to the project specification.

The specified paint; primers, intermediate and topcoat together with their associated thinners shall

be stored in cool dry environments free from heat, heat sources, segregated away for all nakedflames, welding sparks and maintained at room temperature.

Painted items shall be protected from damage by use of non abrasive supports during storage.

Coated surfaces shall be protected from damage during lifting or handling by use of soft packing

between slings where possible. Where damage to painted surface is unavoidable these areas shall

be clearly identified and repaired in accordance with painting and touch up specified in this

procedure

3.4 Release of Fabricated items for Painting


9/62


FAC-2009-CW690260


C0109 WAV


Rev. No.: B



After fabrication and inspection is completed, the fabricated item that has passed all shop

inspection and released by the Quality department shall be considered ready for painting.

All fabricated items shall proceed to blasting and painting operations after all fabrication shop

preparations have been completed. The tag indicating the number of fabricated spool shall be used

for identification, where ever possible all spool number shall be marked on the internal surface or

spool ends before final release for site identification.

3.5 Pre-Surface Preparation

Prior to commencing surface preparation the QC inspector shall ensure that blasting operations donot destroy the traceability numbers or tags. Any material that is found to be untraceable either

before or after blasting and painting operations shall be immediately segregated for separate

identification.

Visual inspection shall be done on the steel surface to detect the presence of oil, grease, wax, dirt

and other foreign matter. If detected solvent cleaning as per SSPC SP1 shall be complied with prior

to any tool or abrasive cleaning. The degreased surface shall be further washed with fresh water to

remove all traces of degreaser chemicals.

All items that are exposed to marine environment will be washed down with potable fresh water to

remove any salt contamination. This procedure shall also be performed on all metal surfaces thatdo not require painting.

Raised face of weld neck flange shall be protected by covering with masking tape and grease.

All weld spatter and residual flux shall be entirely removed. Excessively rough welding, sharp

edges and corners shall be ground relatively smooth prior to abrasive blast cleaning

Blasting shall not be permitted when steel surface is less than 3 degree centigrade above dew

point.

3.6 Surface Preparation

The surface preparation shall be as detailed in section 4.0 COMPANY specification (COM-SU-

2.02-A) on Materials and application of painting and protective coatings (see Attachment D)

loose paint shall be removed and feather edged. All surface irregularities and contamination shall

be removed.

If the surface being prepared lies adjacent to a sound surface which is to be repaired, the surface

preparation shall overlap the coated surface by at least 25mm.The remainder of existing coated surface shall be properly protected with shields or screens to

prevent any possible damage to the coating.

Area with inadequate coating thickness shall be thoroughly cleaned and if necessary abraded.

Additional coat shall be applied blending in with the final coating on adjoining areas.

3.9 Finish Colour

The finish painting colour shall be as detailed in Table 1 and 2 of section 7.2 of COMPANY

primer before welding.

2. This can be done by masking prior to coating or by grinding or sandblasting before welding.

3. The coating-free area shall extend a minimum of two inches (5.08 cm) from the weld bevel.

4. Non-inorganic zinc preconstruction primers shall be removed by blasting to bare metal prior to

application of the required paint system.

5. Supplier shall not apply successive coats over any non-inorganic zinc preconstruction primers

in order to avoid undermining the protection provided by inorganic zinc primers.

3.6 Weld-Through Pr imers

1. Weld-through primers shall not be used unless welding qualification tests show no detrimental

effects, such as unacceptable porosity or mechanical properties.

2. The use of weld-through primers must be reviewed by the Purchaser in writing prior to their
