Zakizade B., Davatgar E.B., 2025, Re-evaluating Security Barriers in Oil and Gas Facilities: Focus on Functionality, Reliability, and Robustness, Chemical Engineering Transactions, 116, 349-354.
Assessing security risks in critical infrastructure, such as oil and gas facilities, presents a complex challenge. Various methods have been developed to address these risks, often utilizing the concept of vulnerability. The American Petroleum Institute's API 780 method defines vulnerability based on internal and external safeguards, whereas other studies draw inspiration from safety barrier assessment principles expressing vulnerability as a function of protective layers. Building on Sklet's (2006) identification of functionality, reliability, and robustness as critical characteristics for effective safety barriers, this research explores these attributes in the context of security barriers at oil and gas facilities. The focus of this research is on how these characteristics are defined in security risk assessment and how security threats can potentially compromise them.
