Abstract:Growing scientific evidence suggests that risks caused by critical infrastructure (CI) failure will increase worldwide due to more frequent and intensive extreme weather events (EWEs) induced by climate change. Those risks are difficult to estimate due to the increasing complexity and interconnectedness of CIs and because information sharing regarding the vulnerabilities of the different CIs is limited. This paper proposes a methodology for risk analysis of systems of interdependent CIs to EWEs and climate change, as developed and carried out for the Port of Rotterdam area in the Netherlands. The case study includes multiple CIs that belong to different sectors and can be affected at the same time by an initiating EWE. Therefore, the methodology proposed supports the assessment of common cause failures that cascade across CIs and sectors, based on a simple, user-friendly approach that can be used by CI owners and operators. From the case study it became clear that the severity of cascading effects is strongly influenced by the states of operation of the different CIs during and after the initiating EWE and that there is a need to raise stakeholders’ awareness of systemic risks.
