The UK Marine Accident Investigation Branch (MAIB) issued the report of its investigation of work undertaken in a dangerous enclosed/confined space and the consequent attempted rescue on board an offshore supply vessel resulting in the loss of three lives off the East Yorkshire coast on 23 September 2007. One crewmember entered the chain locker to do some work and collapsed. The crewmember standing by raised the alarm, entered the chain locker, and also collapsed. A third crewmember donned an Emergency Escape Breathing Device (EEBD) before entering the chain locker. The EEBD became dislodged and the third crewmember collapsed. All three died. There was a failure to recognize that the atmosphere in the chain locker could become oxygen-deficient over time and appropriate precautions were not taken.

Report No. 12/2008 (7/9/08). 

In addition Vanuatu's representative to MAIIF has been collecting information on confined space entry issues from other administrations.  These will be used to support a submission to IMO recommending actions be taken to deal with confined space entry.
