Qualifying Hazards

Hazard Identification (HAZID) and Hazard and Operability (HAZOP) studies form the basis of any risk assessment and an important understanding of potential hazards, possible causes, an assessment of the effectiveness of any safeguards already in place, and identification of possible hazard and risk reduction measures.

Experience has shown that HAZID and HAZOP are best carried out in a team review format with an independent chair, responsible engineers and operational personnel, relevant specialists and key management.

Anatec has chaired many HAZIDs from offshore operations, including offshore construction activities, marine operations, new pipeline designs, decommissioning and novel applications such as a walk to work vessel operating in close proximity to a floating production, storage and offloading (FPSO) vessel.

Anatec has also chaired a number of HAZOPs, including subsea wells, manifolds, flowlines and risers, FPSO topsides process and utility systems, FPSO marine systems and steam boiler / power generation packages, and unusual HAZOPs such as of a flexible riser annulus vent monitoring system. Anatec has also chaired an "End to End" HAZOP to review an entire project's multiple HAZOP studies to identify any omissions or inconsistencies at interfaces.

Anatec has also reviewed and signed-off HAZOP action responses and collated HAZOP action close-out reports.

The HAZID and HAZOP methodology follows best practice including BS EN ISO 17776:2002: Petroleum and natural gas industries - Offshore production installations - Guidance on tools and techniques for hazard identification and risk assessment, and HAZOP - Guide to Best Practice, I Chem E, 2008.
