Question 1

A jockey seat on your commercial RIB is designed for two occupants, but only one passenger is seated on it as you head into rougher-than-expected water. What's the risk?

Accepted Answer

The rearmost occupant normally provides lumbar support to the forward one; a lone occupant has no lateral or lumbar support in the highest-force position on the vessel In the real incident, the passenger was alone in a twin jockey seat with no lumbar support, seated at the bow where vertical motion and peak impact forces are highest. When the vessel slammed into a wave, she reseated with her spine misaligned to the force — fracturing her T12 vertebra.

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.
