Security risk and vulnerability assessment for critical installations

External acts of interference may cause severe accidents in critical installations, such as chemical clusters and process plants. The integration between safety and security is a critical and interdisciplinary issue; the research is aimed at developing innovative approaches for the risk and vulnerability assessment of chemical and process plants affected by external acts of interference.

Main activities:

  • Quantitative assessment of attractiveness and vulnerability of chemical facilities to external acts of interference;
  • Probabilistic risk analysis, implementation of integrated safety and security barriers;
  • Development of strategies for the mitigation of accident scenarios caused by external acts of interference;
  • Characterization of the impact of improvised explosives devices (IED).
