Question 1

Why is your wash (wake) a genuine environmental and safety consideration when passing moored boats, riverbanks, or shallow anchorages at speed?

Accepted Answer

Excessive wash can cause riverbank erosion, disturb nesting birds and other wildlife, and cause moored or anchored boats to surge against their lines or each other — slowing down through sensitive or crowded areas is a simple, standard courtesy and precaution A wake that seems unremarkable from the helm can be a real problem to a moored boat surging on its lines, a riverbank losing material to repeated wash, or ground-nesting birds disturbed off a nest — slowing down through anchorages, moorings, and sensitive banks is a low-cost, high-value habit that avoids all three at once.

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.
