Findings of Buncefield explosion mechanism project available on FABIG website

The final report of the joint industry project which studied the ‘Dispersion and Explosion Characteristics of Large Vapour Clouds’ is now available on the FABIG website from

The work was undertaken following the investigation into the 2005 Buncefield explosion incident, which resulted in a large explosion and a huge fire leading to tremendous damage to the outlying area.

The work has led to the development of a methodology for estimating the size and concentration of a gas cloud following an accidental release of fuel from a storage tank. It has also resulted in a simple method for estimating the overpressure in the areas surrounding the gas cloud in the event of detonation of the cloud. These can be used in hazard assessment and to inform decisions on land use planning. The research has also generated a vast amount of experimental data that is suitable for the development and validation of computer models. The final report is in 2 volumes.


SCI is a key player in research and development of design guidance for hydrocarbon explosion and fire hazards. SCI’s work following the Piper Alpha disaster of 1988 led to publication of the Interim Guidance Notes for the Design and Protection of Topside Structures against Explosion and Fire and the establishment of FABIG. SCI’s experience of managing large joint industry projects contributed to the decision to appoint them as project manager of this major joint industry project.
