What routine maintenance and testing does PSCRB training emphasise for lifeboat engines, beyond the broader vessel's general engine maintenance regime?

A. Lifeboat engines should never be started except during an actual emergency, to preserve fuel and engine life

B. Regular starting and running of the lifeboat engine (as part of scheduled drills, per SOLAS requirements) to confirm it starts reliably and runs correctly, since an engine that has not been tested in months may fail at the exact moment it is needed most, despite looking fine in storage

C. Lifeboat engines require no separate testing from the general vessel maintenance schedule and can be assumed reliable indefinitely

D. Engine testing is solely the responsibility of shore-based maintenance contractors during scheduled dry-dock periods

A. PSCRB is required for every seafarer regardless of muster list role, with no distinction from PST

B. PSCRB only covers liferafts, while PST covers lifeboats — the two trainings simply split equipment types

C. PST gives every seafarer the basic personal survival skills needed to use equipment and survive once in a liferaft, while PSCRB is a separate, more advanced certificate required for crew specifically designated on the muster list to launch, command, or operate lifeboats and rescue boats — including davit operation, engine handling, and craft manoeuvring

D. PSCRB and PST cover identical content and are simply two names for the same training

A. Occupants should stand and hold the gunwale for stability during the lowering process

B. The area below and around the lifeboat is clear of obstructions and personnel not involved in launching; the falls (wires) are correctly led and free to run; the brake mechanism is functioning; occupants are seated and braced correctly; and there is clear communication established between the person controlling the davit and anyone in the boat

C. No pre-launch checks are necessary as long as the davit mechanism appears undamaged on visual inspection

D. Only the lifeboat's engine needs checking before launch; the davit and fall mechanisms are assumed reliable without inspection
