4.5.1 This Standard covers protective coating
requirements for steel structure within cargo oil tanks. It is noted
that there are other independent items that are fitted within the
cargo oil tanks and to which coatings are applied to provide protection
against corrosion.
4.5.2 It is recommended that this Standard is
applied, to the extent practicable, to those portions of means of
access provided for inspection within the areas specified in subsection
4.4 that are not integral to the ship structure, such as rails, independent
platforms, ladders, etc. Other equivalent methods of providing corrosion
protection for 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 stiffener depths for walkways, stringers, etc., are to fully comply
with this Standard when located within the coated areas.
4.5.3 It is also recommended that supports for
piping, measuring devices, etc., be coated as a minimum in accordance
with the non-integral items indicated in paragraph 4.5.2.
