Introduction:

A HAZOP workshop is a structured and systematic review of a process or operation, using a guideword-based methodology to identify potential hazards and operability issues arising from deviations from the design intent.
The study is conducted by a multidisciplinary team and facilitated by an experienced HAZOP leader, ensuring that all credible process deviations (e.g., no flow, high pressure, low temperature) are thoroughly examined. The review is typically performed using P&IDs and other design documents to assess how process parameters may deviate and impact safety, reliability, and performance.

Purpose:

• Identify potential hazards and operability issues resulting from process deviations
• Analyze causes and consequences of deviations from design intent
• Evaluate the adequacy of existing safeguards and control measures
• Recommend additional measures to reduce risk to ALARP
• Improve process safety, operability, and maintainability
• Provide a structured basis for further studies (e.g., SIL/LOPA, QRA)
• Support compliance with international standards and company requirements

Outcomes

• Identification of hazards and operability issues arising from process deviations
• Assessment of causes, consequences, and existing safeguards
• Risk ranking of scenarios to prioritize critical issues
• Actionable recommendations to reduce risks to ALARP
• Basis for SIL/LOPA and design improvements
