SUMMARY

This is the final report of the 'Dispersion and Explosion Characteristics of Large Vapour Clouds' Joint Industry Project. The project’s ultimate objectives were to understand vapour cloud development following large losses of primary containment, the characteristics of explosions involving large flat flammable vapour clouds and the explosion mechanisms that can give rise to very high overpressures over a large area as observed in the Buncefield incident. This has been done through large and medium scale experimental studies supplemented by numerical analysis.

The project report is divided into two volumes. Volume 1 provides an overview and a summary of the work undertaken, the results and the main findings. It draws from the content of Volume 2, which contains the final reports of the individual studies performed as part of the project.
