This report reviews the status of tanker offtake on the UKCS for the period 1998 to August 2004. It is an update on a previous report (www.hse.gov.uk/research/rrhtm/rr111.htm), which covered the period 1998 to 2001.
Incidents involving shuttle tankers had previously been studied in the IMCA, JIP Report M150 Quantified Frequency of Shuttle Tanker Collision During Offtake Operations (Ref. 1) and this report uses a similar approach.
The report provides an overview of the data collected, a calculation of the hours of exposure and the frequencies of incident types. The report concludes that during the period under consideration there was a 74% reduction in the frequency of collision between a shuttle tanker and an FPSO/FSU. Nevertheless there is clearly under-reporting of the near miss information and blurring of the lines between normal operational procedures and emergency procedures on some vessels with respect to emergency disconnection.
