Safety analysis of critical infrastructure impacted by operation and climate-weather changes - theoretical backgrounds

Kołowrocki Krzysztof

Safety and Reliability of Systems and Processes

2021

Summer Safety and Reliability Seminar 2021

The methodology and general approach to critical infrastructure safety and resilience analysis is proposed. The principles of multistate approach to critical infrastructure safety analysis are introduced. There are introduced the notions of critical infrastructure basic safety indicators like, the critical infrastructure safety function, the critical infrastructure risk function and the critical infrastructure fragility curve. The critical infrastructure safety and resilience indicators are proposed to be obtained using probabilistic approach to modelling of operation threats and extreme weather hazard impacts on its assets safety. There are proposed safety and resilience indicators, crucial for operators and users of the critical infrastructure, defined as a complex system in its operating environment. The safety of a critical infrastructure free of any outside impacts is discussed and modelled. The safety indicators of this critical infrastructure are defined. The safety of critical infrastructure impacted by its operation process is considered. The critical infrastructure operation process and its parameters are defined and its characteristics are determined. The safety and resilience indicators of the critical infrastructure related to the operation process impact are proposed. The safety of critical infrastructure impacted by the climate-weather change process at its operating area is considered. The climate-weather change process at the critical infrastructure operating area and its parameters are defined and its characteristics are determined. The safety and resilience indicators of the critical infrastructure related to the climate-weather change process at its operating area impact are proposed. The safety of critical infrastructure impacted by its operation process and climate-weather change process at its operating area is considered. The critical infrastructure operation process related to climate-weather change process at its operating area and its parameters are defined and its characteristics are determined. The safety and resilience indicators of the critical infrastructure impacted by the operation process related to climate-weather change process are proposed. Real critical infrastructures and their assets impacted by their operation processes related to climate-weather change process at their operating area are suggested to be examined and their safety and resilience indicators are proposed to be determined by the proposed methods.

Chemical Spill Due to Extreme Sea Surges. Critical Infrastructure Chemical Accident (Spill) Consequences. Related to Climate-Weather Change

Bogalecka M., Kołowrocki K.

Journal of Polish Safety and Reliability Association

Vol. 9, No. 2

The paper contains the detailed description, preparatory work and necessary data for conduction of Case Study 2: Storm and Sea Surge at Baltic Sea Port, Scenario 2: Chemical Spill Due to Extreme Sea Surges – Critical Infrastructure Chemical Accident (Spill) Consequences Related to Climate-Weather Change in the scope of the EU-CIRCLE project. The general model of critical accident consequences was applied to chemical spill consequences generated by dynamic ship critical infrastructure network operating at the Baltic Sea waters. The approach to the prediction of critical infrastructure accident consequences is proposed. Moreover, the cost analysis of losses associated with the consequences of chemical spill, without and with considering the climate-weather impact, is proposed.
