RR684 - Structural integrity management framework for fixed jacket structures

With many offshore installations in the UK sector of the North Sea now reaching or exceeding their original anticipated design life, there is a particular need to evaluate approaches to structural integrity management by offshore operators to ascertain their adequacy in managing aging structures. In addition to this, a significant proportion of the aging structures are now operated by duty holders who are relatively new to the UKCS, and may not be following recognised good practice for structural integrity management.

A pilot study by HSE, undertaken during 1995-1996 and the results of the KP3 audit programme have highlighted the varying approaches to structural integrity management by duty holders, in terms of both the methods used and their effectiveness.

The objective of the study presented in this document is to develop a comprehensive framework for the structural integrity management (SIM) of fixed jacket structures reflecting the Health and Safety Executive Offshore Division's technical policy. This framework is a medium for communicating what HSE regards as good industry practice and thereby to stimulate duty holders' continual performance improvement.

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 author alone and do not necessarily reflect HSE policy.
