Fire and explosion structural integrity assessment


This document describes the fire and explosion structural integrity inspection and intervention activity.

It involves inspection activity in the duty holder (DH) office and offshore inspection. In order to gain sufficient confidence in ALARP arguments, it is envisaged that a starting point for data input will be the safety case and  hydrocarbon releases.

Appendix 1 provides a template to assess the continuing acceptability of structural integrity (SI) to resist the fire and explosion hazard and the maintenance and repair of relevant safety critical elements (SCE’s). The template has been modified to suit the specific nature of this activity, focusing on design, assessment, as well as in-situ maintenance of SCE’s.


The major emphasis is to provide assurance of life cycle integrity. Therefore, with regards to the management of fire and explosion risks, these interventions aim to review:

The basis of this activity will be to focus on key installations that carry a higher than average fire/explosion risk. Data obtained from the hydrocarbon releases database for attended installations will be a used as a guide for these interventions.

Intended outcomes

There are several intended outcomes of the interventions::


Deliverables will be as follows:

Supporting information

Appendix 2 gives a detailed technical background document and supporting references for this work. The background document must be read and understood by all inspectors to enable the question set (appendix 1) and reports to be properly executed.

Research and technical support needs

There have been many projects on fire and explosion, mainly in the area of hazard quantification. However a few projects on structural response do exist and given in the research and development web pages.
