Question 1

You're hauling prawn gear and the net fouls on the seabed mid-turn, creating a sudden heeling moment. What determined whether Nancy Glen survived this exact scenario?

Accepted Answer

The vessel's remaining stability margin at the time — whether it could resist the heeling moment created by the fouled net A fouled net during a turn is a known, recurring hazard on prawn trawlers that an adequately stable vessel is built to survive. MAIB found Nancy Glen's residual stability had been reduced to the point where this routine event became unsurvivable.

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.
