Under 46 CFR §111.106-3, cargo transfer pumps and associated piping — including fill, discharge, vent, and sounding piping — are subject to which routing restriction?
- A. They must be located in or routed through dedicated cofferdams only
- ✓ They must not be located in or pass through any accommodation, service, or machinery spacesCorrect
- C. They must be separated from other systems by explosion-proof bulkheads but may pass through machinery spaces
- D. They must be routed through the least hazardous location practicable, which may include machinery spaces if no alternative exists
Why B is correct
46 CFR §111.106-3(j) requires that cargo pumping and piping systems be arranged independently from all other systems and expressly prohibits cargo transfer pumps and piping — including fill, discharge, vent, and sounding piping — from being located in or passing through any accommodation, service, or machinery spaces. The cofferdam requirement in §111.106-3(i) is a separate, additional requirement.
