After arrival at the discharge port, the ship’s crew were using the stores crane to deploy the gangway.
The operation involved lifting the gangway down from its stowage position to the main deck, disconnecting the crane, pushing the gangway under the boom conveyor, then re-connecting to the crane to lift outboard.
When raising the empty crane hook, to re-position the crane and re-connect the gangway, the crane wire parted, causing the crane hook to fall to the deck.
- When the crane wire was being hoisted, the winch stalled unexpectedly. The crew member lowered the hook briefly, then re-tried hoisting, when the wire parted.
- The crane wire had been fitted in 2020, and regularly maintained and inspected by the crew. The last inspection by the lifting gear contractor was in August 2021.
- The crane wire had not been overloaded.
- The investigation indicates that the crane wire may have been allowed to become slack at some time previously, leading to a riding turn on the drum.
- Good safety practices on board, and a high level of safety awareness of the crew meant no-one was under the hook as it fell.
