Training Layer of Protection Analysis (LOPA)

Recommended prerequisites: Attendees of this training layer of protection analysis should have strong technical skills and prior training in qualitative hazard evaluation techniques

Are proposed or existing combinations of safeguards enough to prevent an accident or mitigate the consequences? Do you perceive that doing a fully quantitative risk assessment (QRA) would be over-working the problem? Then Layer of Protection Analysis (LOPA) is the new tool you need to learn. LOPA combines both qualitative and quantitative elements of hazard evaluation and risk assessment to analyze and judge the adequacy of existing or proposed safeguards against process deviations and accident scenarios. A key to the success of LOPA is its rules for judging if protection layers are truly independent. Because of these rules, LOPA helps the analysts make consistent judgments of if the risk of scenarios are “as low as reasonably practical (ALARP)”.

 What You Will Learn on this Training Layer of Protection Analysis :

  • When and how to use LOPA and How to systematically create risk scenarios
  • How to establish risk acceptance (risk tolerance) criteria for use within your company (this is also called development of ALARP criteria)
  • How to calculate “as-is” risk for a cause-consequence pair:
  • Estimate the frequency of the initiating event and estimate consequence
  • What is meant by “independence” and “uniqueness” with respect to IPLs
  • How to use LOPA to determine the Safety Integrity Level (SIL) necessary for an instrument IPL (to comply with the requirements of IEC 61508/61511)
  • How other companies worldwide use LOPA to:
  • Decide which PHA/HAZOP recommendations to reject and which to accept
  • Focus limited resources within mechanical integrity departments and operations on what is critical to manage risk to ALARP
  • Avoid wasting resources on quantifying risk using QRA methods
  • Perform specialized risk modeling for facility siting questions

Who Should Attend?

This Training Layer of Protection Analysys course is designed for experienced PHA/HAZOP leaders. Other individuals with a strong technical background (such as engineers and scientists) may attend: Managers of Operations, Safety; Project Managers; Engineers – Process, Safety, and Mechanical; PSM Coordinators and Managers

Training Layer of Protection Analysis Outline

Introduction to LOPA

  • Learning objectives and goals of using the LOPA technique
