Layers of Protection Analysis (LOPA) for Process Safety Management

Venue : KUWAIT
Start Date : 12/10/2025
End Date : 16/10/2025

COURSE OBJECTIVES:

• When and how to use LOPA
• How to identify which scenarios from a HAZOP or other qualitative analysis could benefit from LOPA
• How to systematically create risk scenarios for new processes or for existing processes under change
• How to establish risk acceptance (risk tolerance) criteria for use within your company (this is also called development of ALARP criteria) and how to depict this in a Risk Matrix or in a formula
• How to calculate “as-is” risk for a cause-consequence pair:
  • How to estimate the frequency of the initiating event
  • How to determine the consequence for the scenario (unmitigated)
  • Understand what is meant by “independence” and “uniqueness” with respect to the safeguard layers (IPLs)
• How to calculate the value of each IPL
• How to determine the risk of a LOPA scenario and how to determine how much further risk reduction (if any) is necessary
• 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 for safety instrumented systems)
• How to document LOPA
• 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 the added cost and unproductive sophistication that often occurs when they instead quantify risk using QRA methods such as fault tree and event tree analysis

WHO SHOULD ATTEND?
