A framework for NaTech seismic risk assessment in industrial plants
Abstract
In industrial districts, NaTech events are the causes of relevant accidents. The effects of the release of hazardous substances, the costs involved for rescue and chemical reclamation of ground and groundwater and the economical loss for the company may be enormous if one of such natural and technological events would happen. In order to identify those industrial items for which the seismic risk is high, a new approach based on a census data sheet and multi-criteria analysis taking into account both structural behaviour and industrial hazard is presented. The paper focuses the attention on the vulnerability analysis on refinery items, such as oil storage tanks and reactors/distillation towers.
