Question 1 of 27070

If auxiliary machinery vital to the main propulsion system is not provided with independent duplicate systems, which of the systems listed would satisfy regulations if serviced by two pumps? (46 CFR)

🔍 Key Concepts

• 46 CFR requirements for duplicate or standby pumps on vital systems • What is considered vital to propulsion versus important but not strictly required in duplicate • Differences between condensate, lube oil service, and fuel oil service systems on a steam or motor vessel

💭 Think About

• For each listed system, ask: if this pump fails underway, can I safely continue propulsion, or must I slow/stop immediately? • Which system does 46 CFR specifically require to have at least two pumps, one of which may be driven from the main unit? • Does the regulation treat all three systems the same way, or is there one that clearly has a stricter redundancy requirement for safety of propulsion?

✅ Before You Answer

• Look up the exact 46 CFR section on propulsion and auxiliary machinery redundancy (Subchapter F – Marine Engineering). • Confirm which system is explicitly named in the CFR as needing two pumps when not otherwise duplicated. • Verify whether the regulation groups these systems together or specifies only one of them in the “two pump” requirement.
