Question 1

MAIB SB1/2024 identified alternative arrangements to chain-over-static-pin at the derrick head. Which of the following was NOT one of them?

Accepted Answer

Hydraulic chain tensioning system with load monitoring The three real alternatives cited were wire-and-sheave, a swinging arm mechanism, and a secondary retention wire. A hydraulic tensioning system with load monitoring was not among them. The MAIB noted no reported failures of any of the genuine alternative arrangements in the period surrounding the Honeybourne III 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.
