Risk influence frameworks for activity-related risk analysis during operation: A literature review

Experience gained in the petroleum activities have showed that major accident risk is inherent in daily activities. Risk influence methodology is perceived as a good candidate to model the activity-related risk, as a key input to operational planning decisions. The paper reviews and summarizes 11 risk influence frameworks that integrate organizational and human factors in a structured way. The intention was to evaluate how these frameworks and identified risk influencing factors (RIFs) can be used for activity-related risk analysis. The main conclusion is that it is not necessary to model explicitly RIFs for activity consequence risk - the effect that performing an activity will have on the risk level after the activity has been completed. Operational management RIFs, direct organizational RIFs, personal risk influencing factors, task characteristics RIFs, technical system RIFs, and environmental RIFs are relevant for activity performance risk - the risk associated with performing the action. Operational management RIFs influence planning, which is important to identification of interactions while estimating period risk - the risk for a plant or facility over a period.
