This technique evaluates risks by orders of magnitude of the selected accident scenarios and builds on the information developed in qualitative hazard evaluation.

OBJECTIVES

• Understanding LOPA methodology
• How to execute the detailed steps of the LOPA method for scenario analysis
• How to identify enabling conditions and conditional modifiers
• Closing the risk gap
• Managing LOPA documentation, updates, revalidations and follow-up

MATERI

• Introduction to LOPA
• Developing LOPA Scenarios
• Estimating the Consequence of the Scenario
• Estimating the Likelihood of the Selected Initiating Event
• Estimating the Probability of Failure of Independent Protection Layers
• Calculating the Risk
• Judging the Risk
