MSC 82/24/Add.1 ANNEX 1 Page 2 ANNEX 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 technic
10、al 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 upwards1 for which the building contract is placed, the keels of which are laid or which ar
11、e 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 the Guidelines for the selection, application and maintenance of
12、 corrosion prevention systems of dedicated seawater ballast tanks (resolution A.798(19) and the Guidelines on the enhanced programme of inspections during surveys of bulk carriers and oil tankers (resolution A.744(18), as amended). 2.2 Dew point is the temperature at which air is saturated with mois
13、ture. 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
14、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. It can be either inorgan
15、ic or organic. 2.8 NDFT is the nominal dry film thickness. A 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 t
16、he shipyard after shop-primer application. 1 This Standard applies only to dedicated seawater ballast tanks in all types of ships and double-side skin spaces in bulk carriers which are constructed of steel. MSC 82/24/Add.1 ANNEX 1 Page 3 2.10 Shop-primer is the prefabrication primer coating applied
17、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, o
18、f 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 reac
19、h 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
20、the shipowner, the shipyard and the coating manufacturer and presented to the Administration2 for 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 3.
21、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 t
22、he shipbuilder in order to prevent premature decay and/or deterioration of the coating system; .2 the coating performance can be improved by adopting measures at the ship design stage such as reducing scallops, using rolled profiles, avoiding complex geometric configurations and ensuring that the st
23、ructural configuration permits easy access for tools and to facilitate cleaning, drainage and drying of the space to be coated; and .3 the coating performance standard provided in this document is based on experience from manufacturers, shipyards and ship operators; it is not intended to exclude sui
24、table alternative coating systems, providing a performance at least equivalent to that specified in this Standard is demonstrated. Acceptance criteria for alternative systems are provided in section 8. 2 In accordance with SOLAS regulation I/6, for the purposes of this Standard, the Administration m
25、ay entrust a recognized organization acting on its behalf to determine compliance with the provisions of this Standard.

35、D 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 act
36、ual 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 upwards shal
37、l at least comply with the requirements in this Standard. 4.3 Special application 4.3.1 This Standard covers protective coating requirements for the ships steel structure. It is noted that other independent items are fitted within the tanks to which coatings are applied to provide protection against
38、 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 ships structure, such as rails, independent platforms, ladders, etc. Other equivalent methods of providing corrosion _
