When a davit-launched raft is lowered from a MODU, upon becoming waterborne, the raft is released by __________.
• Davit-launched life raft release mechanisms used on MODUs (Mobile Offshore Drilling Units) • Difference between automatic off‑load release and manual on‑load release • What happens at the moment the raft becomes waterborne and the strain comes off the falls/hook
• Think about what is supposed to happen automatically once the raft is fully in the water and no longer carrying its own weight on the hook. • Ask yourself whether the crew should have to do a deliberate manual action at that exact moment, or if the design is intended to free the raft automatically when the load comes off. • Visualize the sequence: embark passengers, lower on davit, raft touches water, weight comes off the hook—what system or effect actually makes the hook open?
• Verify which option describes an automatic off‑load release that works when the raft is waterborne and the load is removed. • Check which choices clearly require an extra manual action at the critical moment rather than an automatic function built into the hook. • Confirm from training materials that davit‑launched rafts on MODUs are designed so they will release safely when waterborne without relying on precise crew timing.
