HAZOP Workshop

[2-Day Basic Training]


The Hazard and Operability (HAZOP) study is a structured, logical methodology for hazard identification and mitigation which was first used in 1960s by ICI UK. This methodology allows its user to identify all potential undesirable hazardous events and operational problems associated with the operation and activities in process facilities such as chemical plants, LNG plant, refinery, offshore platform and Floating Production Storage and Offloading vessels. HAZOP study is performed by a multi-disciplinary team, who reviews the technical documents about the facility and follows the HAZOP methodology to identify potential undesirable hazardous events and/or operational problems that could occur during normal operations.


  • Using the HAZOP guidewords, identify cause of deviations from normal operating conditions for a process system in a systematic manner;
  • Evaluate the consequence of any incident/accident to personnel safety, environmental pollution and damage to asset;
  • Evaluate the adequacy of the existing safeguards and control measures with respect to safety and operations to prevent or mitigate the consequences of hazards; and
  • Identify and recommend further control measures / safeguards to reduce the risk to as low as reasonably practicable (ALARP).


  • Understanding the HAZOP process steps and HAZOP Rules;
  • Identifying HAZOP Nodes from the Piping and Instrumentation Diagram;
  • Applying HAZOP Guidewords to identify cause of deviation from normal operating conditions for the identified nodes;
  • Determining the consequences of the deviation and identifying safeguards/control measures for the consequences;
  • Recording of HAZOP discussions in HAZOP Worksheets;
  • Preparing standard HAZOP report with the required supporting documents;
  • Preparation required from a HAZOP Chairman in organizing a HAZOP Workshop;
  • Roles and responsibilities of HAZOP Chairman to ensure smooth running of HAZOP session; and
  • Attributes and personnel skills required from HAZOP Chairman.
