Consequence modelling of the hydrocarbon fire at Longford, Australia, 25 September 1998
On 25 September 1998, the Esso gas processing and crude oil stabilization plant at Longford, Victoria, Australia, suffered a loss of containment on a reboiler for a rich oil demethanizer. The release of hydrocarbon formed a vapour cloud, which subsequently ignited. The fire caused 2 fatalities and 8 injuries, and led to a series of escalating fires and explosions. The plant was shut down, causing massive disruption to gas supplies throughout Victoria for 2 weeks. The paper describes a mathematical model of the progression of the accident, prepared by DNV as part of the investigation by the Longford Royal Commission. The model covers the nature of the hydrocarbon, the rate of release, its dispersion through the plant, the ignition, and the subsequent fire and escalation. The model used the consequence assessment program PHAST, with necessary parameters derived from ambient data and tuned to match available evidence from the witnesses to the accident. The paper describes the treatment of uncertainties about many of the input parameters, and shows that the model gave good agreement with nearly all the witness observations. The combination of witness evidence with consequence modelling allows a better understanding of the full course of events than either would alone.
