Question 1

True or False: a multi-boat training exercise is adequately controlled as long as each individual crew is competent and briefed on their own manoeuvre.

Accepted Answer

False — without a designated controller with oversight of all participants, individually competent crews can still collide Individual competence and an individual brief are not the same as coordinated control. On the River Cleddau, each crew may well have understood their own intended manoeuvre — what was missing was anyone with visibility of both boats' plans at once, able to prevent them intersecting dangerously.

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.
