Section 1 General requirements

1.1.1 The painting specification is to be submitted for approval, see Pt 8, Ch 1, 3.5 Coating systems 3.5.1.

1.1.2 Paints, varnishes and similar preparations having nitrocellulose or any other highly flammable base are not to be used in accommodation or machinery spaces or in other areas with an equal or higher fire-risk.

1.1.3 Where a coating is to be applied in accommodation spaces and areas of similar fire-risk, the coating is to have low flame spread characteristics, see Pt 8, Ch 1, 3.5 Coating systems 3.5.2

1.1.4 Paints or other similar coatings containing >10% aluminium by weight in dry film should not be used in positions where flammable vapours may accumulate, unless it has been shown by appropriate tests that the paint to be used does not increase the incendive sparking hazard.

1.1.5 Any sheathing or composition to protect decks is to be applied in such a manner that corrosion will not occur unseen beneath the covering.

1.1.6 Deck coatings or coverings used on decks forming the crown of spaces with a high fire-risk (such as helidecks, machinery and accommodation spaces) or which are within accommodation spaces, control rooms, emergency escape routes, etc. are to be of a type which will not readily ignite, see Pt 8, Ch 1, 3.5 Coating systems 3.5.2

1.1.7 Paints or other coatings are to be suitable for the intended purpose in the locations where they are to be used.

1.1.8 Coatings are to be applied to blast cleaned surfaces prepared to at least an equivalent of ISO 8501-1 Sa 2½. All resulting dust is to be removed from the surface prior to the application of any paint.

1.1.9 The selection, application and maintenance of coatings for dedicated sea-water ballast tanks (including pre-load tanks on self-elevating units), double-side skin spaces, etc. are also to comply with Resolution MSC.215(82) - Performance Standard for Protective Coatings for Dedicated Seawater Ballast Tanks in all Types of Ships and Double-Side Skin Spaces of Bulk Carriers - (Adopted on 8 December 2006) Performance Standards for Protective Coatings. All dedicated sea-water ballast tanks and double-side skin spaces are to comply with all of the requirements of the Resolution.

1.1.10 Maintenance of the protective coating systems is to be included in the unit's overall maintenance scheme.

1.1.11 The paint (and/or primer) used on the inner hull of some LNG containment systems (particularly membrane type) requires the use of a suitable paint system to provide adhesion of the containment system (via a curing mastic) to the inner hull, in accordance with the designer's specification, as approved by LR.
