(41k) Applying Layer of Protection Analysis to Select the Most Robust and Cost Effective Mitigation Strategy

Analyzing process safety risks and applying appropriate mitigations is critical to inherently safer design and maintaining an asset throughout its lifetime. While many tools exist, adopting a “Layer of Protection Analysis” or LOPA framework is a simplified, semi-quantitative method that defines risk as a function of the frequency and consequence of an incident scenario.

Process safety and budgetary concerns are occasionally at odds; utilizing a LOPA framework can be a powerful tool to balance these two concerns and implement the plan that both provides ample process protection and is cost effective.

In this presentation, we will analyze a case study of how LOPA may be applied to a reboiler system to select the most effective tools to mitigate risk to an acceptable level.
