Question 1

In the week before the grounding, the Crystal Stream skipper had roughly 24 hours' rest across six days, and just over four hours in the 24 hours before the accident &mdash; well below the minimum rest requirements in working time regulations for fishermen. What if you, as skipper, felt "okay" at the start of a lone night watch despite a similar pattern of short rest over recent days? What does this case suggest about that feeling?

Accepted Answer

Feeling okay in the moment is not reliable once rest has been this low for this long &mdash; cumulative fatigue erodes judgement, including the judgement about whether you are too tired to be on watch alone, so the actual rest figures over the last 24 hours and the last several days matter more than how you feel right now The MAIB's finding was not that the skipper made one poor decision at midnight &mdash; it was that, by then, his capacity to stay awake had already been compromised by days of insufficient rest, well below the minimum required by working time regulations for fishermen. The report's lesson is that "feeling fine" is exactly the kind of self-assessment that severe cumulative fatigue degrades; tracking and acting on actual rest figures &mdash; not how alert you feel &mdash; is what should determine whether a lone night watch is safe to stand.

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.
