Published 17 May 2012

Key issues:

  • Crewman fell overboard during cargo operations when using the pilot gate instead of the accommodation ladder to get onto the quay.
  • The pilot gate was not an authorised means of access alongside, but was a significant shortcut that was occasionally used by some of the crew.
  • The dangers of using the pilot gate increased as the vessel’s freeboard increased during cargo operations.
  • The deceased either slipped or lost his balance as he stepped from the ship to the quay.
