Painting General Requirements for
New Construction
GP 56-02-02
Scope
1) The purpose of this Global Practice (GP) is to define the minimum requirements for selection,
application, and quality control for coatings applied to new construction facilities and structures, both
onshore and offshore. It is a combination of the previous versions of the prior onshore and offshore
coating GPs. Maintenance painting and coating for field managed modification projects is covered
separately in GP 56-02-11.
2) For Midstream applications only, GP 19-04-01 is used for internal coatings and GP 19-77-03 for
underground tanks/separators.
3) The appendices provide references to specific coatings for piping, equipment, and structures based on
service and environment.
4) Tanks of bolted construction, as well as tanks and vessels constructed of nonmetallic materials are
outside the scope of this GP.
5) Buried or immersed pipelines are covered separately in GP 56-02-01.

DEC 2018
Equipment
1) Coating shall be applied using only equipment recommended by Coating Manufacturer's PDS. The
equipment shall be clean and regularly serviced in line with the equipment manufacturer's requirements
and must perform within the equipment manufacturer's tolerances.
2) Spray tips shall be regularly inspected to ensure that they meet the specification stated on the
published Coating Manufacturer's datasheet. Spray tips shall not be modified or remanufactured to
meet these requirements and shall be as supplied by the equipment manufacturer. Tips worn beyond
the stated specification shall be immediately discarded.
3) With the exception of stripe coats, conventional or airless spray is the preferred application method
for liquid coatings. Stripe coats shall be applied by brush only with the coating thoroughly worked in
around edges. See Section 9.3.7 for details.
4) Paint brushes and rollers shall be compatible with the coating material and only used if an approved
application method in Manufacturer's PDS. Application shall be interrupted if there is visual
evidence of bristles or roller lint contaminating freshly applied coating. Brushes/rollers shall be
replaced. If the problem persists, then Coating Manufacturer shall be consulted for recommendations
as to the appropriate equipment.
5) Heating, air-conditioning, or dehumidification equipment may be required to meet the requirements
of this GP (refer to Section 7 for details) and to achieve the agreed-upon schedule.
9.3.4.
Surface Damage/Imperfections
1) Runs, sags, voids, drips, overspray, loss of adhesion, blistering, peeling, mudcracking, inadequate
cure, or rusting of the substrate shall not be permitted.
2) Where shop coating has been damaged in transit or where damage has occurred to field coats, the
following shall apply:
a) All damaged and loosely adhering coating shall be removed and the surface thoroughly cleaned.
b) Edges of the breaks shall be feathered and the designated number of prime, intermediate, and
finish coats applied. The requirements of Section 11 of this GP shall apply when making repairs.
c) The finish coat for repairs shall match the original color and gloss.
3) Damaged coatings shall be retouched before succeeding coats are applied.
9.3.5.
Color
1) The specific topcoat color for a given surface should be as indicated in Appendix A of this GP unless
otherwise identified in the project specific documentation.
2) Contractor shall bring to the attention of Company if the proposed color scheme contravenes local
regulatory requirements at the point of project installation.
3) The color of successive coats shall vary slightly from the color of preceding coats to permit easy
identification without affecting finish color.
9.3.6.
Stainless Steels
1) Paints containing low melting point metal pigments such as lead, cadmium, or zinc shall not be used
to overcoat stainless steel materials. Such paints shall not be applied in proximity to stainless steel
where the stainless steel could be contaminated.

[A] Color designations are per RAL Classic Color System. All colors are subject to project
approval and may be revised or modified to match existing colors, and as such should not
require a specification deviation.
Note not used.
Surfaces using an epoxy passive fireproofing (PFP) shall utilize System Z, or the system
recommended by the PFP Manufacturer. See GP 70-01-05 for guidance on placement and types
of PFP.
Note not used.
Individual components of skid-mounted units shall be coated as noted for each item listed in this
schedule or as allowed by Note 23.
Faying surfaces of painted steel members designed for high-strength bolting in friction-type
joints shall be primed only. The primer shall be certified by Coating Manufacturer to have been
rated by testing to provide the slip class required by the structural design (Class A or B). Do not
paint galvanized faying surfaces.
Paint used for shop marking and materials identification shall be compatible with subsequent
finish coats.
Identification numbers shall be placed on all plant equipment (e.g., pipe, vessels, pumps,
exchangers, etc.) and shall correspond to the Piping and Instrumentation Drawing (P&ID)
numbers. Lettering or stenciling shall be a minimum of 50 mm (2 in.) high and shall be of a
contrasting color. Incoming and exiting line service shall be identified in a similar manner; 25
mm (1 in.) or smaller lettering is acceptable. Stencil color shall be distinctly different color from
background paint and should be consistent throughout the facility. For Midstream tank
applications, refer to Appendix D for detailed tank labeling requirements.
The following requirements apply to the exterior of storage tanks for Upstream:
(a) On tank roofs that are painted white, an area 1.6 m (5 ft) in diameter surrounding gauging
hatches shall be painted black with the urethane finish for the system listed in Table B–1.
(b) Storage tanks shall be inscribed with the date of painting and/or cleaning. Letters 25 mm (1
in.) high, with 3 mm (0.12 in) stroke characters and numerals, shall be painted on the tank with
the red urethane finish for the systems listed in Table B–1.
(c) Inscriptions shall be as follows:
(i) "SHELL PAINT (date)" shall be painted on the shell 200 mm (8 in.) above the edge of the
manhole cover closest to the product inlet and outlet nozzles. The inscription shall straddle
the vertical centerline of the manhole.
(ii) "ROOF PAINTED (date)" shall be painted 25 mm (1 in.) above the inscription given in
Item (i.)
(iii) "CLEANED (date)" shall be painted on the manhole cover 150 mm (6 in.) above the
centerline.
(iv) "INTERIOR LINED (date)" shall be painted 25 mm (1 in.) above the inscription given in
Item (ii.) The date in each inscription shall consist of the month and year only, in that
order, and both shall be indicated in numbers (e.g., "7-02" for July 2002.)
(d) See Note 8. An identification number shall be painted on each tank in a location readily
visible to plant operators. For Midstream tank applications, refer to Appendix D for detailed
tank labeling requirements.
(10)
Do not paint stainless instrument and control tubing.
(11)
See GP 66-01-03 for details.

[A] If an economic evaluation determines that the cathodic protection system alone is more cost
effective, then the coating system may be deleted with Company approval.
(13)
Surface preparation and coating for subsea insulated equipment shall be as qualified by subsea
insulation supplier, and shall conform to NORSOK M-501 system 9 or equivalent. See GP 6508-01 for details.
(14)
Apply broadcast-type skid-resistant coating material in two stages. Broadcast skid resistant
#30–#40 Aluminum Oxide Grit into surface of wet second coat of Epoxy. Sweep up excessive
grit when dry. Using roller, apply "Epoxy Finish" to seal over grit.
(15)
Apply TSA in accordance with GP 56-02-08. In those instances where an option is allowed in
Table B–1, System D is preferred. However, the alternative coating system may be used if
design life is less than 15 years or economic analysis proves the alternative system to be more
economical during the life cycle.
(16)
Refer to GP 29-01-03 for stainless steel operating temperature limits. Upstream stainless steels
include 304/316/300 Series Austenitic Stainless Steel, 22Cr Duplex, 25Cr Super Duplex, and
6Mo Super Austenitic. Stainless steel shall not be coated with zinc pigmented or zinc-rich
coatings including TSZ, epoxy zinc, IOZ, etc.
(17)
Coating system A shall not be used where surfaces may be exposed to mechanical ice removal
or the use of deicing salts – System C must be used.
(18)
Note not used.
(19)
The extent of coating is as follows:
Sheet Piles—All surfaces both sides except the interlocking groove.
Pipe Piles—Exterior surface only from top of pile to at least 3 m (10 ft) below the mud line.
Additional coating length may be required to achieve cathodic protection for the pile structure
and/or adjacent structure.
(20)
If lined, stencil "Lined Vessel – No Hot Work" in characters at least 8 cm (3 in.) high on side of
tank or, for ballast tanks, on deck. This caution should be within 1 m (3 ft) of each personnel
entry hatch.
(21)
Commence blasting and coating work only after completion of all "hot work," both within the
tank and on exterior surfaces of substrates that will be coated on their interiors.
(22)
For tanks in hydrocarbon service, coat entire tank bottom and at least 1 m (3 ft) of sides or
expected high water level if greater and surfaces where water is expected to condense. Tanks in
other services shall be 100% internally coated.
(23)
[A] Manufacturer’s system shall have surface preparation of SP10 minimum, and DFT 250
micron (10 mil) minimum. If manufacturer’s system does not meet these minimum
requirements, with Company approval, refinish components and equipment delivered with
Vendor's standard factory finish with System "L."
(24)
Color does not require an exact match to a specific color chip. Use Coating Manufacturer's
standard version for this color in the specified product.
(25)
[R] Where practicable, alternate methods to insulation for providing personnel protection should
be considered (e.g., cages.)
(26)
Only for buried piping within battery limits. For pipelines, refer to GP 56-02-01.

Modifications
Date: 07/06
This Version reflects a document that has been changed throughout. The
overall objective of these changes is to:
(1) Include new standards that codify practices and procedures
previously described less precisely in the text.
(2) Identify contemporary coating products expressly indicated by their
Coating Manufacturers as appropriate for use in conjunction with this
GP. All Coating Manufacturers were given an opportunity to review this
version to ensure their understanding of the context/service in which
their products would be used.
(3) Incorporate details once relegated to notes by relocated to the text.
(4) Provide details that reflect lessons learned. In particular, the
topsides/onshore primer now includes organic zinc-rich epoxy rather
than being solely reliant on ethyl silicate inorganic zinc. Rub tests are
prescribed to ensure IZ is properly cured prior to overcoating and to
confirm that prior coats of an epoxy lining will be receptive to
overcoating (i.e., are demonstrably within their maximum recoat times).
(5) Add details, including sketches, to optimize tie-in and repair details.
Individuals interested in performing a side-by-side comparison between
this version and the prior version (1.1) can obtain a copy of that version
from the EMEPS editorial staff.

Description
*
Assigned to paragraphs that require the Owner's Engineer to provide additional information or
make a decision.
A
Assigned to paragraphs that require approval from the Owner's Engineer before the work may
proceed or the design is finalized.
C
Assigned to paragraphs whose primary purpose is reduced costs. Reduced cost in this context
refers to initial investment cost and does not include life cycle cost considerations. Life cycle cost
considerations are captured under reliability, maintainability, or operability purpose codes.
E
Assigned to paragraphs whose primary purpose is driven by environmental considerations.
Environmental considerations typically include specifications intended to protect against
emissions/leakage to the air, water, and/or soil. Deviations from the specifications contained in
such paragraphs require formal review and approval according to local environmental policy.
I
Assigned to paragraphs that provide only clarifying information, such as Scope statements,
definitions of terms, etc.
M
Assigned to paragraphs whose primary purpose is to provide for maintainability of equipment or
systems. Maintainability provisions are those that facilitate the performance of maintenance on
equipment/systems either during downtimes or during onstream operations.
O
Assigned to paragraphs whose primary purpose is to assure operability of equipment or systems.
Operability is the ability of the equipment/system to perform satisfactorily even though conditions
are off-design, such as during start-ups, process swings, subcomponent malfunction, etc.
R
Assigned to paragraphs whose primary purpose is to improve or assure the reliability of equipment
or systems. Reliability is a measure of the ability of equipment/systems to operate without
malfunction or failure between planned maintenance interventions.
S
Assigned to paragraphs containing specifications/guidance where the primary purpose is the
avoidance of incidents impacting personnel safety, process safety, and the public in general and/or
involving responses to emergency situations. Any deviation from the specifications contained in
such designated paragraphs requires formal review and approval according to local safety policy.
Personnel Safety:
Refers to the prevention of incident-related personnel injuries or illness, e.g.,
burns, cuts, abrasions, inhalation of or exposure to dangerous substances,
etc., that could result in medical treatment, restricted work, lost-time
incidents, or fatalities.
Process Safety:
Refers to the prevention and control of process releases, fires, and/or
explosions that could result in damage to equipment, process disruption, or
personnel injury or illness.
Purpose Code Hierarchy: Purpose Codes assigned to a numbered item apply to all associated subitems.
Purpose codes assigned to an individual subitem apply only to that subitem.
