Abstract

Seismic hazard represents one of the possible triggering causes for NaTech accidents in refineries and production plants. The vulnerability of steel storage tanks was evaluated within the framework of a rapid risk assessment. This paper reports the results of the investigation. The outputs of the analysis are plotted on normalized axes and trends among the results are observed. Finally, a comparison between the criticalities and the fragility curves found in the literature is proposed
