An able seaman on bulk carrier Coresky OL (IMO 9692741) died when a cable snapped after too much tension was applied, causing securing equipment to recoil, an investigation has found. The vessel was loading logs in Gisborne at the Eastland Port, New Zealand. on the night of April 3rd, the New Zealand Transport Accident Investigation Commission said in its final report on the accident, released on June 23rd.
The incident occurred after the crew used a crane to tension a wire rope to help secure a load of logs to the ship’s deck.
Chief Investigator of Accidents Aaron Holman said that the crew of the bulk carrier were using a crane to tension a wire rope to secure a load of logs to the ship’s deck. The wire rope had been “zig-zagged like a single bootlace over the cargo” through several pulleys secured by foot wires running up the sides of the cargo, with two able seamen standing near the wire rope to monitor the tension being applied by the crane.
A foot wire parted after the heaving stopped, causing the securing equipment to recoil. Part of the equipment then struck and fatally injured one of the able seamen.
The load applied by the crane, along with the configuration of the pulleys used to tension the securing wires, caused the wire to snap, Holman said.
The vessel’s crew did not have enough information on the hazards associated with wires under tension, and the cargo securing manual did not provide guidance on a safe system of work for cargo securing operations.
“The manual was silent on this because the operator’s safety management system didn’t include a safety assessment for cargo securing operations,” said Holman.
Coresky OL’s operator, the Shih Wei Navigation Co. Ltd. of Taiwan, has been recommended to carry out a comprehensive safety assessment for vessels carrying deck log cargo.
