Question 1

BSU's investigation into the SEAHAKE rescue boat accident ruled out two obvious explanations before finding the real cause. What were they?

Accepted Answer

Incorrect operation by the crew, and externally visible material fatigue BSU explicitly ruled out operator error and visible fatigue first. The crew had followed procedure correctly and there was nothing to see from an external inspection — the defect was inside a sealed bearing housing. This is why BSU's own classification records no human-factors contribution to this accident.

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.
