Oil fuel transfer pumps are not considered as oil fuel units.

Regulation II-2/9.3.1 Penetrations in fire-resistive divisions and prevention of heat transmission This regulation should be applied to all penetrations at the exterior boundaries of superstructures and deckhouses which, according to SOLAS regulation II-2/9.2.4.2.5, are required to be A-60 class insulated. Regulation II-2/10.7.1.4 Fixed gas fire-extinguishing systems for general cargo 1 Non-combustible cargoes, such as materials listed in paragraph 1 of Annex 2 to the FTP Code, need not be mentioned on exemption certificates issued under regulation II-2/10.7.1.4. 2 The document of compliance with regulation II-2/19 may not permit more cargoes than indicated in the list of cargoes attached to the exemption certificate issued under regulation II-2/10.7.1.4.
