Abstract
One of the main triggering causes of industrial accidents is associated with the occurrence of natural events, like earthquakes, floods, tsunamis, hurricanes, or lightning storms. These phenomena can lead to structural damage to the industrial facilities causing the release of hazardous substances contained within them, initiating a chain of unpredictable cascading effects, potentially involving pool fire, blasts, or dispersion of toxic cloud. The study of the effects of the impact of natural phenomena on industrial facilities is the evaluation of the NaTech risk assessment. The term NaTech has been coined to describe such natural-hazard-triggered technological accidents. The thesis presents a multi-hazard NaTech risk assessment for a petrochemical plant of an anchored storage tank farm exposed to earthquakes and tsunamis. This hypothetical waterfront liquefied petroleum gas tank farm is situated at a coastal Italian site supposed as case study. Advanced probabilistic seismic hazard analysis and tsunami fragility functions for anchored storage tanks are developed, in this thesis, to contribute to a risk assessment that is not always easy to carry out. These two contributions are added to existing literature about probabilistic tsunami hazard analysis and seismic fragility curves, in order to integrate the hazard and vulnerability results for seismic and tsunami action and to provide the rates of the tank failure, where failure is intended as structural damage able to cause release of contents. The results of the work of the thesis can be used to perform loss and consequence analysis looking at a wider context of multi-risk that takes into consideration the interaction between two natural phenomena.
