Session: Quantitative Risk Assessment Methods Beyond Hazard and Operability (HAZOP) Analysis

While many hazards can be identified during a Hazard and Operability (HAZOP) analysis, some may be too complex to evaluate with this methodology. Some scenarios may fall into the high consequence, low frequency category, and others may be high consequence, high frequency. How do we analyze these high-consequence hazards? Is there a quantitative method better suited to assess the risk? QRA, LOPA, or other? This session will focus on practical applications and examples of methodologies, beyond a HAZOP, that have been successful.
