Q: True or False: after the near-identical chain failure on Isla S in September 2022, Macduff Shellfish reported the incident to the MAIB and reviewed the chain-over-static-pin design as a fleet-wide risk.

False — the incident wasn't reported, and the arrangement itself was never reviewed as a design risk Macduff's internal investigation attributed the Isla S failure to 'an unidentified hairline crack,' issued guidance on inspection frequency, and moved on. The incident was never reported to the MAIB, and the chain-over-static-pin design itself was never reassessed — the same failure mode recurred fatally 13 months later.

Question 1

True or False: after the near-identical chain failure on Isla S in September 2022, Macduff Shellfish reported the incident to the MAIB and reviewed the chain-over-static-pin design as a fleet-wide risk.

Accepted Answer

False &mdash; the incident wasn't reported, and the arrangement itself was never reviewed as a design risk Macduff's internal investigation attributed the Isla S failure to 'an unidentified hairline crack,' issued guidance on inspection frequency, and moved on. The incident was never reported to the MAIB, and the chain-over-static-pin design itself was never reassessed — the same failure mode recurred fatally 13 months later.

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.
