Abstract

Risk assessment of existing structures is mandatory to ensure appropriate operation of industrial and civil engineering systems. The need for a coherent and adapted methodology becomes more and more challenging in various engineering fields, knowing the large amount of equipment and their aging profiles, on the one hand, and the limitations for re-investment capacity, on the other hand. This paper provides an overview of the available risk assessment methodologies, which are classified into three categories: condition-based, risk-based and reliability-based approaches. Three industrial case studies are considered to compare the various methodologies, in order to identify their advantages and drawbacks. It becomes apparent that a unified approach for risk assessment has to be developed to fit the engineering requirements in terms of lifetime management of industrial systems.
