RR566 - Accident statistics for fixed offshore units on the UK Continental Shelf 1980-2005

In 2000, a project was undertaken by Det Norske Veritas (DNV) on behalf of the UK Health & Safety Executive (HSE) with the purpose of obtaining accident statistics for offshore floating units on the UK Continental Shelf (UKCS). In this respect, four databases holding information about incidents having occurred on floating units on the UKCS were interrogated. The survey revealed that that none of them had a complete recording of such incidents. Consequently, the event frequencies being obtained varied with the availability of sources.

There was no reason to believe that the situation and figures for fixed installations should be any different. Hence, it was proposed to initiate a series of projects, but addressing all types of risks to fixed units. It should be noted that fixed units in this project are defined as comprising all bottom-fixed structures, but excluding TLPs, FPSOs, FSUs and production jackups even though they are “fixed” during their production phase. The most recent project related to fixed units, Accident Statistics for Fixed 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 RR349.

This report and the work it describes were funded by the Health and Safety Executive (HSE). Its contents, including any opinions and/or conclusions expressed, are those of the authors alone and do not necessarily reflect HSE policy.
