PERFORMANCE STANDARD FOR PROTECTIVE COATINGS FOR DEDICATED SEAWATER BALLAST TANKS IN ALL TYPES OF SHIPS

AND DOUBLE-SIDE SKIN SPACES OF BULK CARRIERS

1 PURPOSE

This Standard provides technical requirements for protective coatings in dedicated seawater ballast tanks of all type of ships of not less than 500 gross tonnage and double-side skin spaces arranged in bulk carriers of 150 m in length and upward1 for which the building contract is placed, the keels of which are laid or which are delivered on or after the dates referred to in SOLAS regulation II-1/3-2 as adopted by resolution MSC.216(82).

2 DEFINITIONS

For the purpose of this Standard, the following definitions apply: 2.1 Ballast tanks are those as defined in resolutions A.798(19) and A.744(18). 2.2 Dew point is the temperature at which air is saturated with moisture. 2.3 DFT is dry film thickness. 2.4 Dust is loose particle matter present on a surface prepared for painting, arising from blast-cleaning or other surface preparation processes, or resulting from the action of the environment. 2.5 Edge grinding is the treatment of edge before secondary surface preparation. 2.6 GOOD condition is the condition with minor spot rusting as defined in resolution A.744(18). 2.7 Hard coating is a coating that chemically converts during its curing process or a non-convertible air drying coating which may be used for maintenance purposes. Can be either inorganic or organic. 2.8 NDFT is the nominal dry film thickness. 90/10 practice means that 90% of all thickness measurements shall be greater than or equal to NDFT and none of the remaining 10% measurements shall be below 0.9 x NDFT. 2.9 Primer coat is the first coat of the coating system applied in the shipyard after shop primer application. 2.10 Shop-primer is the prefabrication primer coating applied to steel plates, often in automatic plants (and before the first coat of a coating system). 2.11 Stripe coating is painting of edges, welds, hard to reach areas, etc., to ensure good paint adhesion and proper paint thickness in critical areas. 2.12 Target useful life is the target value, in years, of the durability for which the coating system is designed. 2.13 Technical Data Sheet is paint manufacturers Product Data Sheet which contains detailed technical instruction and information relevant to the coating and its application.

3 GENERAL PRINCIPLES

3.1 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. All these aspects contribute to the good performance of the coating system. 3.2 Inspection of surface preparation and coating processes shall be agreed upon between the shipowner, the shipyard and the coating manufacturer and presented to the Administration for

27

review. The Administration may, if it so requires, participate in the agreement process. Clear evidence of these inspections shall be reported and be included in the Coating Technical File (CTF) (see paragraph 3.4). 3.3 When considering the Standard provided in section 4, the following is to be taken into account:

.1 it is essential that specifications, procedures and the various different steps in the coating application process (including, but not limited to, surface preparation) are strictly applied by the shipbuilder in order to prevent premature decay and/or deterioration of the coating system;

4 COATING STANDARD

4.1 Performance standard This 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 actual useful life will vary, depending on numerous variables including actual conditions encountered in service.

4.2 Standard application Protective coatings for dedicated seawater ballast tanks of all ship types and double-side skin spaces arranged in bulk carriers of 150 m in length and upward shall at least comply with the requirements in this Standard.

4.3 Special application 4.3.1 This Standard covers protective coating requirements for the ship steel structure. It is noted

that other independent items are fitted within the tanks to which coatings are applied to provide protection against corrosion.

4.3.2 It is recommended that this Standard is applied, to the extent possible, to those portions of permanent means of access provided for inspection not integral to the ship structure, such as rails, independent platforms, ladders, etc. Other equivalent methods of providing corrosion protection for the non-integral items may also be used, provided they do not impair the performance of the coatings of the surrounding structure. Access arrangements that are integral to the ship structure, such as increased stiffener depths for walkways, stringers, etc., are to fully comply with this Standard.

4.3.3 It is also recommended that supports for piping, measuring devices, etc., be coated in accordance with the non-integral items indicated in paragraph 4.3.2.

4.4 Basic coating requirements 4.4.1 The requirements for protective coating systems to be applied at ship construction for

29

dedicated seawater ballast tanks of all ship types and double-side skin spaces arranged in bulk carriers of 150 m in length and upward meeting the performance standard specified in paragraph 4.1 are listed in table 1.

4.4.2 Coating manufacturers shall provide a specification of the protective coating system to satisfy the requirements of table 1.

4.4.3 The Administration shall verify the Technical Data Sheet and Statement of Compliance or Type Approval Certificate for the protective coating system.

4.4.4 The shipyard shall apply the protective coating in accordance with the verified Technical Data Sheet and its own verified application procedures.

2.5 edges 2007/1/31

PSPC 2.5 reads: Edge grinding is the treatment of edge before secondary surface preparation.

Edges mean all sharp edges (non-radiused or with a radius less than 2 mm). Which includes both thermally and mechanically edges. All sharp edges (non - radiused or radius less than 2mm) are subject to edge grinding. All edges with the exception of the natural rounded edges of sections (or profiled steel bars) are subject to two stripe coats.
