ABSTRACT
Risk communication and information exchange have become more challenging in today’s complex projects, which involves different stakeholders in different roles. Unstructured data communication and flaws in knowledge exchange may lead to erroneous risk perception and evaluation. The role of risk analysis has become more critical in this perspective. This paper proposes a new way to enrich risk analysis with the help of knowledge of systems engineering. Focus is given to establish a Failure Mode, Effect and Criticality Analysis (FMECA) model using models from systems engineering which are more systematic compared to models used in tradition approach. A reference case study is analyzed, which is inspired from the subsea laboratory at the Department of Mechanical and Industrial Engineering (MTP) at the Norwegian University of Science and Technology (NTNU). The investigation focuses on the series of relevant risks for the subsea gas boosting section in offshore Oil & Gas installations. Results from the present study are discussed with emphasize on three aspects: (1) cross-system effects, (2) reasonable and reachable risk reduction measures and (3) multiple system dimension. We acknowledge that the proposed method based on system thinking can be used to construct system behavior model, which in turn could be used in FMECA development to gain better understanding of risks and to improve the overall performance of system.
