LOPA and HAZOP cannot be compared directly, as these two are different techniques with different goals. LOPA complements HAZOP or other hazard identification methodologies. 

  • HAZOP is ideally suited for brainstorming or uncovering what could go wrong and at identifying potential accident scenarios; a HAZOP team can also qualita- tively judge the risk of a scenario.

  • LOPA allows the analyst to take a predefined scenario and estimate the risk of the scenario in a consistent and simplified manner.
