Operations performed on Floating Production Storage and Offloading (FPSO) units involve many hazards, and these operations are inherently dangerous. Therefore, it is vital to establish safe environments where operability and maintainability are ensured by these systems. On FPSO units, especially confined space entry and operations, include a variety of critical risks and threats. The study proposes to use the Principles (capabilities) of Resilience Engineering (RE) as a new perspective to control and reduce potential risks that occur during confined space entry and operations. Also, the performances of these abilities are determined. If these capacities were identified and extended, this would make the confined space activities more resilient and safer. The results of the study show the proactive ability and usefulness of the RE in enabling the avoidance, mitigation, recovery, and survival from threats.
