RR567 - Accident statistics for floating offshore units on the UK Continental Shelf 1980-2005

In 1999, during a project undertaken by DNV on behalf of the UK Health & Safety Executive (HSE), four databases holding information about UK Continental Shelf (UKCS) semi-submersible flooding incidents were interrogated. The survey revealed that that none of them had a complete recording of such incidents. In addition, it was identified that there were incidents which were not recorded in any of these sources. Consequently, the event frequencies being obtained varied with the availability of sources. There was no reason to believe that the situation and figures for other types of events on floating units should be any different. Hence, it was proposed to initiate a series of projects, but addressing all types of risks to floating units. The most recent one, Accident Statistics for Floating Offshore Units on the UK Continental Shelf 1980 – 2003, was completed in 2005. This current project updates the data of the previous project by two further years, 2004 and 2005. This report supersedes Research Report RR353.
