Question 1

Your vessel's liferaft is fitted with a Hydrostatic Release Unit (HRU) and a painter designed to pull free and trigger inflation. What is the correct attachment point for the painter's end, and why does it matter?

Accepted Answer

The HRU's designated weak link, specifically, so the required pulling force is generated as the raft floats free — securing it to an unrelated strong point instead means the force needed to inflate the raft is never applied On Ben Thomas, the liferaft's painter had been secured to a strong point rather than the HRU's weak link. This meant that even once the HRU released the raft canister, the pulling force needed to extract and inflate the raft was never generated — the raft never inflated. This is a specific, verifiable rigging detail worth checking directly, not assuming from "the liferaft looks properly stowed."

Question 2

You're asked to test a deck crane grab after electrical repairs nearby. As the grab is hoisted, what should have happened first?

Accepted Answer

The area within the grab's swing radius should be cleared of personnel before the lift On the bulk carrier Fairfield Eagle, a crew member working nearby was struck and fatally injured when a grab being test-lifted after repairs swung unexpectedly. The investigation found the area should have been cleared and barriered before the test lift began.

Question 3

A toolbox talk held before a lifting operation should explicitly cover which of the following?

Accepted Answer

Who must remain clear of the exclusion zone while the lift takes place A toolbox talk exists to make sure everyone present understands the danger zones, the abort signal, and — critically — who must not be in the area while the lift happens. The RMIMA investigation into the Fairfield Eagle fatality found the toolbox talk had not made this clear.
