Course overview
[Placeholder — replace with real copy] This intensive four-day workshop equips engineers with the skills to lead effective HAZOP studies and conduct SIL determination using LOPA and Risk Graph methods. Highly practical in nature, delegates work through real P&ID case studies and apply IEC 61511 Layer of Protection Analysis. Ideal for process safety engineers, instrumentation engineers, and SIS practitioners seeking to validate or extend their competency.
Prerequisites
Delegates should have at least 2 years of experience in process engineering or a process safety-related discipline. Familiarity with P&IDs is essential.
Who should attend
Target group
Process safety engineers, instrumentation engineers, and HAZOP team leaders who need to lead studies, calibrate SIL determinations using LOPA / Risk Graph, and challenge consultants competently. Best taken after PS01 or with equivalent experience.
What you will learn
- 1Lead a HAZOP study from preparation through to report writing using industry-standard methodology
- 2Apply LOPA to determine SIL requirements for Safety Instrumented Functions
- 3Use the Risk Graph method as an alternative SIL determination technique
- 4Interpret and apply IEC 61511 requirements for SIL determination and verification
- 5Identify common HAZOP pitfalls and how to avoid them in real studies
