Under 46 CFR §111.106-3, cargo transfer pumps and associated piping on a vessel carrying flammable cargo must be arranged in which manner?
- A. Cargo piping may pass through machinery spaces provided it is enclosed in a cofferdam for the full length of the passage
- ✓ Cargo pumping and piping systems must be arranged independently and must not be located in or pass through accommodation, service, or machinery spacesCorrect
- C. Cargo piping may share a common manifold with ballast piping provided the systems are valved off when not in use
- D. Submerged cargo pump motors may be installed in cargo tanks without further approval provided flashpoint exceeds 60 °C
Why B is correct
46 CFR §111.106-3(j) requires cargo pumping and piping systems to be arranged independently from all other systems, and cargo transfer pumps and piping must not be located in or pass through any accommodation, service, or machinery spaces. Option D is incorrect because §111.106-3(f) requires Commandant concept approval and MSC plan approval for submerged pump motors in tanks with flashpoints not exceeding 60 °C that do not meet §111.105-31(d).
