Report on Trends in Shuttle Tanker Incidents 1998-2001

This report reviews the status of tanker offtake on the UKCS as of 1997/8 from a report produced at this time (Ref 1) and uses this approach to analyse data from 1998 to 2001.

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 there has been a 59% reduction in the expected frequency of collision between a shuttle tanker and an FPSO/FSU.

Nevertheless there is clearly underreporting and blurring of the lines between normal operational procedures and emergency procedures on some vessels with respect to emergency disconnection.
