PAINTING SPECIFICATION
1.
SCOPE
This specification covers the requirements for the selection of coating materials, surface preparation,
application procedures and inspection for protective coatings to be applied during construction and
installation of offshore installations and associated facilities.
2.
GENERAL PAINTING REQUIREMENTS
2.1.
General
Selection of coating systems and application procedures shall be made with due consideration to
conditions during fabrication, installation and service of the installation.
2.2.
Planning
All activities shall be fully incorporated in the fabrication plan.
Details of management, inspectors, operators, facilities, equipment and qualified procedures shall be
established and documented before commencing works.
Steel surfaces shall be blast cleaned and coated prior to installation.
2.3.
Unpainted Surfaces
The following items shall not be coated unless otherwise specified:

Aluminum,
titanium,
uninsulated
stainless
steel,
insulated
stainless
steel
heating/ventilation/air-conditioning ducts, chrome plated, nickel plated, copper, brass, lead,
plastic or similar;

Galvanized surfaces except for safety color coding

Jacketing materials on insulated surfaces
If stainless steel is connected to carbon steel, the stainless steel part shall be coated 50mm beyond
the weld zone onto the stainless steel. For piping and pressure vessels, the coating for the stainless
steel part shall not contain metallic zinc.
2.4.
Handling and Shipping of Coated Items
Coated items shall be carefully handled to avoid damage to coated surfaces. No handling shall be
performed before the coating system is cured to an acceptable level. Packing, handling and storage
facilities shall be of non-metallic type.
3.
SURFACE PREPARATION
3.1.
General
All surfaces to be abrasive blasted (using garnets or copper slags) shall be cleaned with an
appropriate detergent and/or solvent as necessary to remove all oil, grease, dirt or other foreign
material.
All sharp edges, weld areas shall be grinded or chipped as necessary to remove weld spatter, flux,
etc.
When the relative humidity is greater than 85% or when the metal temperature is less than 3oC above
dew point, no blasting shall be performed.
3.2.
Inspection and Testing Prior to Blasting Application
Check welded areas are free from undercuts, spatter, flux and other foreign material.

PAINTING SPECIFICATION
Check environment condition, use bacharach sling psychrometer for measurement of relative humidity
and dew point temperature and digital temperature gauge for measurement of surface metal
temperature.
Compressor shall be checked every 4 hours so that the compressed air is free from water and oil
using a white cloth for 60 seconds. If oil or water appears on the cloth, blow down the traps and
separators. Repeat until no further water and oil appear on cloth. Air at blasting nozzle shall not be
less than 6.2 barg.
Check quality of abrasive material, i.e. size and mesh, free from oil and water. Chloride content shall
not exceed 100 ppm.
For internal coating of vessels, all welds shall be ground off to a rounded smooth contour. Stripe
coating (using roller) of all welds and other irregular or hardly coated area is required.
All sharp edges/corners shall be removed or ground off to a 3mm smooth radius unless noted
otherwise.
3.3.
Inspection and Testing After Blasting Application
Check surface preparation visually, the surface cleanliness shall be in accordance with the specified
specification. ISO 8501-1 shall be used as pictorial comparator.
Check anchor pattern using surface profile comparator Elcometer 125 as per ISO 8503.
Inspection shall be carried out to check any incomplete blasting and surface cleanliness.
Paint shall be applied in the same day after inspection of surface preparation (maximum 4 hours).
4.
PAINTING / COATING APPLICATION
4.1.
General
Surface shall be clean, dust free and dry before coating application.
All outdoor coating shall be finished one hour prior to sundown or when metal surface temperatures
are at least 3oC above the dew point.
Paint shall not be applied when the relative humidity is greater than 85% or when surface temperature
is lower than 5oC.
All painting material shall be furnished from original manufacturer’s unopened container, shall be kept
covered and protected. Batch number and identification shall be part of painting record. The paint
material exceed the paint manufacturer’s shelf life shall be rejected.
For internal coating of vessel, all welds and other irregular or hardly coated area shall be painted first
using brush application.
All painting application shall be done strictly in
recommendation.
4.2.
accordance with paint
manufacturer’s
Inspection and Testing Prior to Painting Application
Check ambient and surface temperature.
Surface preparation cleanliness and anchor pattern shall be checked using surface comparator.
Check relative humidity and dew point.
4.3.
Inspection and Testing after Painting Application
Check DFT using Elcometer digital coating thickness gauge and number of locations as per SSPC.
Check paint surface are smooth continuous unbroken coating and free from sags, runs, spots, or
other defect.
