14.2.1 Steel Construction: Vessels which have
the machinery space boundaries constructed of steel, require no additional
fire protection. However, surfaces on the opposite side of the machinery
space should only be coated with finishes which have a Class 1 surface
spread of flame rating when tested in accordance with Standards Annex 13.
14.2.2 Fibre Reinforced Plastic (FRP) Construction:
Machinery space boundaries should prevent the passage of smoke and
flame for 15 minutes, when tested in accordance with the procedure
shown in Annex 9. Fire resistance of FRP
may be achieved by the use of woven roving glass layers or additives
(which must be added strictly in accordance with the manufacturer's
requirements) to the resin. Intumescent polyester, epoxy, vinylester
or phenolic resin surface coatings may also be used; however, solvent
borne intumescent paints are not acceptable. The Certifying Authority
may waive the requirement for the test described in Annex 9 ( Fire Test) if the construction complies with an ISO
or equivalent standard to give at least the same level of protection.
14.2.3 Aluminium and Wood Construction: Machinery
space boundaries should have an equivalent level of fire protection
when compared to FRP construction.
14.2.4 Where insulation is fitted to provide an
equivalent level of fire protection to that required in Section 14.2.2
or 14.2.3 the insulation need not be fitted lower than 300 mm below
the waterline. (It should be noted that insulation approved by the
Administration as satisfying the requirements of an A or B Class division
for the construction material, and division scantlings, will exceed
these requirements.)
