Britain’s Marine Accident Investigating Branch, MAIB, has identified a deck fitting overloaded due to unco-ordinated use of winches, a lift operation interrupted and the master’s concentration broken by the arrival of the vessel’s commercial agent and a lifting operation not identified as a key shipboard operation in the collapse of an A Frame on the floating sheerleg Cormorant. Consequently, no risk assessment had been carried out and there were no written procedures provided.

Says the MAIB report: “At 1001 on 7 March 2010, the 85 tonne ‘A’ frame on board the Netherlands registered floating sheerleg Cormorant collapsed on to the deck while being lifted into position. Substantial damage was caused to the wheelhouse, the ‘A’ frame and its supporting frames, and to deck fittings.
