Modern HAZOP Process

As Hazard and Operability (HAZOP) studies are now recognised world-wide as being the qualitative risk assessment methodology of choice in the Process Industries, there will be additional focus on this specific aspect of Process Hazard Analysis.

 

Course Objectives of HAZOP Process

• Understand the concepts of Risk Assessment and Risk Management

• Understand the estimation and evaluation of risks - Qualitative, Semi-Quantitative and Quantified Risks

• Techniques for Hazard Identification and Analysis - Check-Lists, Risk Profiling, HAZOP, FMEA and Task-Based Risk Assessment

• Cause-Consequences Analysis - The Role of Fault Trees and Event Trees in Accident Prevention

• Understand the requirements of a Team Leader or Facilitator, scribe and team members during HAZOP studies
