3.4 General requirements
3.4.1 It is the responsibility of the coating inspector
to inspect whether the coatings of the shipyards are in compliance with IMO
PSPC standards. The responsibility of the classification society is to inspect
the product approval certificate of coatings, check the qualification of
coating inspectors, examine the technical coating documentation, sample and
monitor the examination carried out by the coating inspectors.
3.4.2 The PSPC coating standard is based on
specifications and requirements which intend to provide a target useful coating
life of 15 years, which is considered to be the time period, from initial
application over which the coating system is intended to remain in good
condition. The ability of the coating system to reach its target useful life
depends on the type of coating system, steel preparation, application and
coating inspection and maintenance. The actual useful life will vary, depending
on numerous variables, the ship’s coating application has significant influence
to the purpose it intends.
3.4.3 The coating system
applied in accordance with the relevant requirements of the PSPC upon the
request of the applicator, may be assigned with the following notations
respectively for the spaces to be coated after satisfactory survey:
(1) Dedicated seawater ballast
tanks (defined in 3.2) PSPC(B)
(mandatory by the Convention)
(2) Double-side skin spaces of bulk carriers (defined in
3.3) PSPC(D)
(mandatory by the Convention)

employed as the primary means for corrosion protection for PMAs that are not
integral to the ship structure. Hot dip galvanizing is to be performed in
accordance with ISO 1461:1999. The galvanized items are to be subsequently
coated to ISO 12944-5:2007 or the coating manufacturer’s recommendation. The
type of paint is to be selected considering its compatibility requirements with
the galvanized surface in accordance with the coating manufacturer’s
recommendation.
3.4.7 Where protective coating is applied as the sole
means of corrosion protection for PMAs that are not integral to the ship
structure, the requirements for specific spaces where these PMAs are fitted are
to be applied to the extent possible. In such cases, the protective coating is
to at least comply with the requirements for the job specification, coating
system (epoxy-based system) and total NDFT.
3.4.8 It is also recommended that supports for piping,
measuring devices, etc., are to be coated in
accordance with the provisions for non-integral items indicated in 4.4.2 and
4.4.3.

3.5.13 Inspection for ships in-service
3.5.13.1 The CTF is to be kept onboard the ship within
the ship’s life service and to be supplemented with relevant information 3
3.5.13.2 Maintenance, repair and local recoating are to
be recorded in CTF (including plate renewal).
3.5.13.3 Where overall recoating is carried out, it is to
be recorded in CTF in accordance with the requirements of new construction
survey.
3.6 PSPC coating standard
3.6.1 Coating manufacturer is to provide Technical Data
Sheet of protective coating system meeting the following requirements. Site
surveyor is to check the coating specification, Technical Data Sheet and
approval certificate. Shipyard is to carry out coating implementation and
coating protection in accordance with the verified coating specification,
Technical Data Sheet and coating procedures checked by the yard itself.
3.6.2 Design of coating system
3.6.2.1 The selection of the
coating system is to be considered by the parties involved with respect to the
service conditions and planned maintenance. Coating manufacturer is to have
products with documented satisfactory performance records and technical data
sheets. The following aspects, among other things are to be considered:
1) location of space relative to heated
surfaces;
2) frequency of ballasting and deballasting
operations;
3) required surface conditions; required
surface cleanliness and dryness; and
4) supplementary cathodic protections, if any
(where coating is supplemented by cathodic protection, the coating is to be
compatible with the cathodic protection system).
3.6.3 Selection of color of coating system
3.6.3.1 A multi-coat system
with each coat of contrasting color is recommended. The top coat is to be of a
light color in order to facilitate in-service inspection. Top coat of a coating
system for ballast tanks is to be of a light color, which reflects light to an
extent that a simple flash light (hand torch) will make inspection easy and
fast, normally light grey, buff, off-white, swimming pool blue/green etc.
easily distinguishable from rust.
3.6.4 Coating Application Specification
3.6.4.1 There are to be a minimum of two
stripe coats and two spray coats, except that the second stripe coat, by way of
welded seams only, may be reduced in scope where it is proven that the NDFT can
be met by the coats applied, in order to avoid unnecessary over-thickness. Any
reduction in scope of the second stripe coat is to be fully detailed in the
CTF.
3.6.4.2 Stripe coats are to be applied by
brush or roller. A roller can be used for drain hole, scallop, etc. but not for
edges and welds.
3.6.4.3 Each main coating layer is to be appropriately
cured before application of the next coat, in accordance with coating
manufacturer's recommendations. Surface contaminants such as rust, grease,
dust, salt, oil, etc., is to be removed prior to painting with proper method
according to the paint manufacturer's recommendation. Abrasive inclusions
embedded in the coating are to be removed. Job specifications are to be
compiled by shipyard in accordance with the recommendation from supplier,
including the dry-to-recoat time and walk-on time given by the manufacturer,
coating protection plan, scaffold setting up and pollution and damage control
for the constructing personnel.
3.6.5 Nominal total dry film thickness (NDFT)
3.6.5.1 NDFT is to reach the specified value of Technical
Data Sheet of coating. (NDFT 320 μm with 90/10 rule for epoxy-based coatings;
other systems to coating manufacturer’s specifications)
3.6.5.2 Maximum total dry film thickness is to meet the
manufacturer's detailed specifications. Care is to be taken to avoid increasing
the thickness in an exaggerated way. Thickness measuring instrument is to be
controlled. Thinner is to be limited to those types and quantities recommended
by the manufacturer.
3.6.6 Pre-preparation of steel plate
3.6.6.1 Steel plate is to reaches Sa 2? class with
profiles between 30-75 μm and salinity≤ 50 mg/m2 NaCl after the
primary surface preparation.
3.6.6.2 Blasting is not to be carried out when the
relative humidity is above 85% or the surface temperature of steel is less than
3°C above the dew point.
3.6.6.3 The cleanliness and roughness profile of the
steel surface are to be checked at the end of the surface preparation and
before the application of the primer, in accordance with the manufacturer's
recommendations and the salt on surface is also to be measured. (Grade
assessment of preparation of steel plates after overall cleaning is to be
carried out in compliance with ISO8501-1 or GB/T8923-1988, surface roughness in
compliance with ISO8503-1/2, soluble salts measurement in compliance with
ISO8502-9 or GB/T18570-9-2005. Conductivity measured is to be fully converted
to density of NaC1 of steel plate surface.)
3.6.6.4 Regarding of the difficulty to carry out the
inspection for shop primer coating equipment of automatic plants in compliance
with the requirements of PSPC 6.2, quality control is a more practical way to
meet PSPC requirements. According to requirements of PSPC, it is the
responsibility for the coating inspector to confirm that the quality control
procedures are in compliance with PSPC.
The quality control of coating equipment of shop primer
automatic plant includes the following procedures.
i. procedures
for management of the blasting grit, including measurement of salt and
contaminants;
ii. procedures recording the surface temperature of
steel, the relative humidity and the dew point;
iii. procedures for controlling and monitoring surface
cleanness, surface profile, oil, grease and dust and other contamination;
iv. procedures recording/measuring soluble salts;
v. procedures for verifying thickness and curing of the
shop primer conform to the values specified in the coating specifications.
3.6.6.5 hop primer is to apply the coating with zinc
containing inhibitor free zinc silicate based or equivalent.
3.6.7 Secondary surface preparation
3.6.7.1 Sa2? on damaged shop primer and welds.
3.6.7.2 If the compatibility of the shop primer and the
main coating to be applied is confirmed by CCS products approval certificate,
intact shop primer may be retained. The retained shop primer is to be cleaned
by sweep blasting, high-pressure water washing or equivalent method. Otherwise,
Sa 2 is to be achieved by removing at least 70% of intact shop primer. .
3.6.7.3 Before coating on main layer, the steel surface
is to be prepared so that the coating selected can achieve an even distribution
at the required NDFT and have an adequate adhesion by removing sharp edges,
grinding weld beads and removing weld spatter and any other surface
contaminants. Steel surface is to reach P2 grade specified in ISO8501-3. Free
edges of members are to be treated to a rounded radius of minimum 2 mm, or
subjected to three pass grinding or at least equivalent process before
painting. Where dedicated form-grinding tools are use, one pass grinding may be
treated as equivalent process.
3.6.7.4 Profile requirements: In case of full or partial
blasting 30-75 μm, otherwise as recommended by the coating manufacturer.
3.6.7.5 Dust Control: Dust quantity rating "1"
for dust size class "3", "4" or "5". Lower dust
size classes are to be removed if visible on the surface to be coated without
magnification. The dust distribution and size measurement are to be carried out
in accordance with ISO8502-3:1993 or GB/T 18570.3-2005. Lower dust size is the
size less than class “3” as the above measurement standards, and is to be
removed if visible to the eye when accumulated. Where it is addressed in the
coating inspection agreement, visual inspection may be accepted at premise of
consentience by the both parties.
3.6.7.6 Water soluble salts limit: ≤ 50 mg/m2 of sodium
chloride after blasting/ grinding. Soluble salts measurement is to be in
compliance with ISO8502-9:1998 or GB/T18570-9-2005. Conductivity measured is to
be fully converted to density of soluble salts of steel plate surface. The
interval of salt measurement and the handling of non-conformity are to be in
compliance with the stipulations of coating inspection agreement, the interval
is generally not to be less than one point for each block.
3.6.7.7 Others: Confirm that there is no oil, water,
mark, zinc powder primer, sootiness and other contaminants.
3.6.8 Surface treatment for erected welds zone
3.6.8.1 The erected welds zone means coating damage of
butt welds and fillet welds and their adjacent heated affect zones when the
block assembly is fitted after it is coated. The width of both sides for butt
welds is usually not more than 200mm (refer to the assembly code figure as
follows). For pre-welded fillet welds kept for erection, the width of each side
is not exceed 300mm and both sides are not exceed 100mm respectively (shown in
the following figure). The weld zone of hatch coaming and hull assembly of bulk
carrier is also belong to the erected welds zone.
3.6.8.2 Surface treatment after erection
1) Butts St 3 or better or Sa2? if applicable.
2) Other requirements are the same as requirements for
secondary surface preparation.
3.6.9 Treatment of coating damage
3.6.9.1 Damages up to 2% of total area: St3.
Contiguous damages over 25 m2 or over 2% of the total area of the
tank, Sa 2? is to be applied for areas of damage and surface treatment after
erection. Coating in overlap is to be feathered. For the rest, is required as
the same as the secondary surface preparation.
3.6.9.2 Damaged area of coating layer refers to the area
where the damage reaches the shop primer or steel surface (exposed steel
plate);
3.6.9.3 Contiguous damage refers to coating damages where
the individual damage is at a distance of not exceeding 100mm.
3.6.9.4 The percent of the damaged area is the ratio of
the damaged area needing repair to the total tank area in the stage of block
assembly/erection. Erection butt is excluded in the percent calculating.
3.6.9.5 The damaged area may be determined by the coating
inspectors assigned by ship owner, shipyard and coating manufacturer in the
agreement before commencement. While dispute arises, the method of scribing
matrix on the photos and calculating area may be used for large damage area and
direct measure of the length may be used for linear damage.
3.6.9.6 The damaged area of tight fillet weld refers to
fillet weld not carried out tightness testing and the bared plating not coated
at the both sides of weld during the block stage, it is not taken for the
coating damage calculation.
3.7 Miscellaneous
3.7.1 Adequate ventilation is necessary for the proper
drying and curing of coating. Ventilation is to maintained throughout the
application process and for a period after application is completed, as
recommended by the coating manufacturer.
3.7.2 Coating is to be applied under controlled humidity
and surface conditions, in accordance with the manufacturer's specifications.
In addition, coating is not to be applied when:
1) the relative humidity is above 85%; or
2) the surface temperature is less than 3°C above the dew
point.
3.7.3 Destructive testing is to be avoided during the
inspection.
3.7.4 Dry film thickness is to be measured after each
coat for quality control purpose and the total dry film thickness is to be
verified after completion of final coat, using appropriate thickness gauges.
Where dry film thickness measurement of former coat layer is carried out for
quality control, a representative position is to be selected and the
measurement result needs not to record in coating technical files. But
measurement control of dry film thickness is to be carried out in accordance
with the requirements for measurement of construction inspection procedures of
the shipyard.
3.7.5 Any defective areas, e.g., pin-holes, bubbles,
voids, etc., are to be marked up and repaired effected. All such repairs are to
be re-checked by coating inspector and documented.
3.7.6 Emphasis is to be placed on initiation of each
stage of surface preparation and coating application as improper work is
extremely difficult to correct later in the coating progress. Where defects and
omitting items of the accepted structure, welding and outfitting and less
defects on surface preparation and coating are found during the inspection,
coating inspector is to be informed.
3.7.7 During the coating inspection, large amount of
defects or serious defects of the surface preparation and coating are found,
the coating inspection is to be discussed immediately, a new repairing plan is
to be made and record in CTF. Where dispute raises for the inspection result
between ship owner, shipyard and coating manufacturer, it is to be settled in
accordance with the flowchart stipulated in CTF.
3.7.8 The proportion of sampling inspection may be once a
month. At least one inspection is to be performed at each of the three stages
of the PSPC implementation, including stage of steel plate preparation, block
stage, erection stage. And at least the items are to be sampled such as
salinity, profile, cleanliness, dust control, dry film thickness, environment
control of blasting/coating, coating log, and coating damage assessment after
erection. (Note: The proportion of sampling inspection for block assembly is 5%
total number of the PSPC coating blocks.

There are to be a minimum of
two stripe coats and two spray coats, except that the second stripe coat, by
way of welded seams only, may be reduced in scope where it is proven that the
NDFT can be met by the coats applied, in order to avoid unnecessary
over-thickness. Any reduction in scope of the second stripe coat is to be fully
detailed in the CTF.
Stripe coats are to be applied
by brush or roller. Stripe coats are to be applied as a coherent film showing
good film formation and no visible defects. The application method employed is
to insure that all areas that require stripe coating are properly coated by
brush or roller. A roller may be used for scallops, ratholes etc., but not for
edges and welds.
Stripe coats may be carried
out either before or after the painting.
5.8 Ambient conditions for painting have been defined
....................................... □
Adequate ventilation is
necessary for the proper drying and curing of coating. Ventilation
is to be maintained throughout the application process and for a period after
application is completed, as recommended by the coating manufacturer.
Coating is to be applied under
controlled humidity and surface conditions, in accordance with the
manufacturer's specifications. In addition, blasting and profile not be applied
when:
(1) the relative humidity is
above 85%; or
(2) the surface temperature is less than 3°C above the
dew point.
6 Repairing after erection
6.1 Damaged area has been defined
.................................................................. □
Damaged area means the area
where the damage is extended to the steel surface.
The adjacent coating damage means the coating damage with
the minimum distance less than 100mm between each damage area.
The damaged area proportion calculation is the ratio
between damaged area calculated at repairing and total area of the tanks after
the coated structure blocks are erected, not taking consideration of the erection
weld area.
6.2 Assessment and measurement methods for damaged areas
have been defined ... □
The calculation method for damaged area and final
technical decision method are to be defined. If there is no dispute,
diagrammatic method may be adopted (it may apply ASTM D610 or ISO 4628-3).
6.3 Erecting weld has been defined
.................................................................. □
Generally, the erecting weld area (including angle weld)
is located around the erecting weld with the tape-shaped areas not exceeding
200mm on both sides. The burnt damage on the opposite side due to erection is
also to be included in the erection weld area. Where it is the remained
non-welded angle weld due to butting of girders or frames between blocks, the
erection weld area is in the range of 100mm around the weld. If coating has not
applied during the block stage due to leakage testing is carried out for the
angle welds on the watertight bulkheads of the boundaries of tanks, such angle
weld may be included in the erection weld area ( it is permitted to be treated
to St 3, excluding the range of 2%).
6.4 Damage treatment has been defined
............................................................ □
Where the coating damaged area does not exceed 2% of
total coating area (the erection weld is not included), the damage area is
permitted to be St 3. Where it exceed 2% of total coating area, or the total
areas of adjacent coating damage exceed 25m2, the coating damage
area is at least to be Sa 2.5.
