Boat's hook not quite hooked

摘要

A ferry was at dock for the evening and a technician was on board to troubleshoot a problem with the rescue boat davit. To allow the technician to access the accumulator chamber of the davit the rescue boat was lowered to the water and the fall slightly slackened. The rescue boat, uncrewea, remained floating in the water while the technician charged the hydraulic accumulator with nitrogen, which took about 20 minutes. During this time the fall was slack, the lifting shackle and the hook resting on :he rescue boat. Once the davit accumulator had been charged, a crew member raised the rescue boat from the water using the davit while an engineer and the technician stood by and observed. From their positions on deck 6, the witnesses could see the rescue boat as it was being raised; however, they could not see how the hook and the lifting shackle were positioned.
