LOPAWorkshop

A 3-day Workshop designed for those who wish to develop their understanding and skills when leading, participating in or verifying a LOPA study, with the option to complete two case studies after the Workshop to attain =Method Certification in LOPA Study.

Course Content

    Introduction to LOPA

  1. Determine when a LOPA is required
  2. How to perform a LOPA
  3. What happens after the LOPA
  4. Alignment with IEC 61511

    Elements of LOPA

  1. Defining the hazardous scenario
  2. Understanding tolerable risk criteria 
  3. Understanding initiating events and assigning a frequency 
  4. Defining Independent Protection Layers 
  5. Assigning Conditional modifiers to initiating events (Enabling Events)
  6. Determining SIL and PFD

    Hazard and Risk Assessment and Functional Safety

  1. LOPA is part of a process, not an end in itself
  2. The legal and regulatory background to Hazard and Risk Assessment (and LOPA)
  3. H&RA (and LOPA) in the functional safety lifecycle
  4. Hazard Identification prior to LOPA 

    LOPA 

  1. Define the scenario
  2. Assign severity and target frequency
  3. Initiating events and frequency 
  4. Enabling events / Conditional Modifiers
  5. Independent Protection Layers
  6. Output Results (SIL, PFD) 

    LOPA techniques

  1. LOPA maths
  2. Developing scenarios
  3. The LOPA team
  4. Tolerable and individual risk
  5. Cost benefit analysis and ALARP
  6. Data sources for failure rates
  7. Human error failure rates
  8. Alarms as IPLs
  9. Common cause failures
  10. Documenting the LOPA

    What follows the LOPA

  1. Verification of the LOPA
  2. The Safety Requirement Specification (SRS)
  3. Stage 1 Functional Safety Assessment
  4. The functional safety lifecycle (design, install, commission, validate, operate, maintain, repair)
  5. Monitoring the assumptions of the LOPA during operations

Who should attend

Anyone who is leading, participating in or verifying a LOPA study.

After this Workshop

After this Workshop you will be able to

What you will get

Case Studies

For an additional fee, candidates can attain Certification in LOPA Study, through the submission of two case studies, using the techniques and templates from the Workshop. These are designed to give delegates the confidence and competence to undertake simple LOPA Studies in this aspect of Process Safety. You will be appointed with a tutor to help in this process with =Method Certification in LOPA awarded on successful completion of the case studies and your CPD hours increased accordingly. Certification is valid for 5 years.
