Abstract

This paper investigates the usefulness of the Hazard and Operability technique, (HAZOP) as a tool for predicting relevant accident scenarios by applying this technique, together with a specific design analysis technique, in a Dutch steelworks. Adaptation of the hazop guide words to the steelworks process functions enables the identification of possible production deviations in the newly built ladle arc furnace and in the transport to and from the furnace. The deviations, which are all related to disturbances in the production process, are clustered on a common consequence base and by assigning high and low incidence grades to the clusters, 13 accident scenarios can be formulated. Reviewing 16 months of experience with the ladle arc furnace shows that 58% of actual deviations can be brought under the defined production-related accident scenarios. Another 28% can be explained by introducing three additional maintenance-related accident scenarios.
