Review of unidentified ignition sources of unplanned flammable releases – Comparison of Offshore and Onshore data
This Report was prepared to compare the frequency of ignition of unplanned and uncontrolled releases of flammable gases, liquids and vapours from onshore sources, with those from offshore releases, and to estimate the proportion of undefined ignition sources from major accidents. The offshore releases were analysed in previous Report FS/04/13 Offshore ignition probability arguments by Dr. AM Thyer of Fire Section at HSL Buxton. The probability of ignition has also been modelled by an spreadsheet, prepared by AEA Technology Ltd at the request of the U.K. Offshore Operators Association (UKOOA). This has been reported elsewhere as the Ignition Probability Review and Model Development Report (2003). This model has a quite extensive interaction between contributing factors which demonstrates the difficulty in clearly identifying ignition sources from incidents which have occurred.
