A Multiperspective Model for Environmental Risk Assessment in Oil and Gas Industries

-

Abstract

The motivation of this article is the way of ranking hazards through ERA (Environmental Risk Assessment), espacially in O&G industries (Oil & Gas). The paper reviews the related literature, and proposes a flexible ERA model incorporating several risk measures, such as risk impact, risk vulnerabilityt, risk exposure, risk manageability, risk controllability, risk urgency, risk growth, risk probability, risk detection, risk timeframe, risk effect delay, risk awareness, and risk outrage. The model was applied in risk assessment of a storage room of hazardous chemicals in a real-world problem. The results showed that the most important hazard was explosion of the storage. After this major hazard, ranking are explosion, then toxic hazard and leackage.
