Overview
Layers of Protection Analysis (LOPA) is a risk assessment method used to determine the likelihood of a scenario occurring based on existing safeguards in order to protect against identified hazard scenarios and to identify any potential shortfall in the risk reduction required to meet predetermined, risk-based criteria.
The Process Safety Leadership Group (PSLG) prepared specific guidance for the applications of LOPA to determine the required safety integrity level (SIL) for overfill protection of highly flammable fuel bulk storage tanks at sites like Buncefield, which was the location of a major incident in 2005.
This course will draw on that guidance, its relevance to LOPA assessment in general and examples of pitfalls identified during the assessment of many LOPA studies from the petrochemical industry.
The course is presented by a member of the PSLG LOPA working group that developed the LOPA guidance.
Learning outcomes
Delegates will be provided with information that will help them to:
- Know when to use LOPA or another more suitable method
- Know how to perform a basic LOPA
- Understand how to produce an effective LOPA, including preparation for detailed LOPA assessment and risk assessment requirements
- Be able to produce a meaningful LOPA study within their business
What the course will cover
The course will begin by putting LOPA in perspective, looking at its uses and its complexity, letting delegates know when to use LOPA and when to consider other methods such as a Quantitative Risk Assessment (QRA). Delegates will look at LOPA study prerequisites and preparation, target frequencies, input data sources and uncertainty. It will cover how to perform LOPA: LOPA rules and IEC 61511 requirements, scenarios, conditional modifiers, enabling events and independent protection/mitigation layers. Delegates will examine LOPA outcomes: regulator expectations and ALARP considerations along with human factors. There are interactive learning elements where delegates will look at example pitfalls associated with LOPA and also consider case study examples.
Who should attend?
The course is aimed at those engineers, managers and safety professionals who have a basic knowledge of risk assessment, possibly gained through Hazard and Operability (HAZOP) studies and Process Hazard Analysis (PHA) studies, and would like to have an understanding of the LOPA method, how to apply LOPA and the pitfalls commonly associated with this type of analysis.
