Bund overtopping - the consequences following catastrophic failure of large volume liquid storage vessels

Abstract

A review has been carried out of the consequences of catastrophic failure of large volume liquid storages leading to ''instantaneous'' release of the vessel contents. Theoretical and practical work reported in the literature indicate that secondary containments may not be able to cope with the sudden release of large amounts of material. The SRD computer code GASP was used to predict the areas of spread and vaporisation rates from pools of flammable/toxic liquids resulting from failures of vessels containing liquids (petrol) and refrigerated liquefied gases (methane, propane and chlorine). The areas of spread of the pools were defined in terms of (a) all material retained by the bund, (b) 50% of material overtopping the bund, and (c) unrestricted spread of the pool. The SRD computer codes DENZ and CRUNCH were used to predict the downwind concentration of the dispersing gas clouds. The efficacy of well designed secondary containment is shown by the much smaller distances at which hazardous concentrations of the vapour clouds would be expected when all the released material is retained by the bund.
