Question 1

As skipper of an open-hold vessel, you're forecast a fresh-to-strong wind. What does CHRISTELLE MIKAEL's loss demonstrate about the actual risk of a sudden, unstable weather front, compared to a steady forecast wind increase?

Accepted Answer

An unstable front can cause wind speed to roughly triple in under 15 minutes, with wave heights potentially double the forecast significant height — a much faster deterioration than a steady increase In CHRISTELLE MIKAEL's case, wind speed went from 15 to 40-50 knots in under 15 minutes as a cold, unstable front crossed the coast — confirmed independently by two weather stations. BEAmer's conclusion specifically notes that gusts can exceed the mean wind by 40% and wave heights can reach twice the significant height in these conditions, particularly dangerous in a reef-strewn area near low water.

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.
