MAIB Investigation Report

Ever Elite investigation report published 14 July 2010

Key issues:

  • A seaman drowned after falling from a suspended accommodation ladder when its hoist winch failed.
  • It was routine practice for seamen to stand on the accommodation ladder when the vessel was underway. This was unnecessary and a safe system of work had not been put in place. Fall prevention equipment was not used and the seaman was not wearing a lifejacket.
  • The hoist winch gearbox failed because it had been incorrectly reassembled. It had not been identified as lifting equipment and therefore had not been maintained in accordance with the UK's lifting equipment regulations.
  • The international standard for accommodation ladder winch design and construction does not reflect current best practice and its application would not necessarily have eliminated several single points of failure within the hoist system.
