Our Expertise

With one of the largest UK teams of professionally qualified and accredited Chairmen, Theon has executed hundreds of HAZOPs for Oil and Gas projects worldwide. The projects have included onshore and offshore facilities including drilling operations, pipelines, platforms, FPSOs, Gas Oil Separation Plants, Onshore Terminals, utilities systems, chemical treatment facilities, tank farms, on/off loading facilities and specialist vendor packages.

Our HAZOP durations have ranged from half a day to four years. We have particular experience in executing complex multi-Billion Dollar projects with technical nuances such as high H2S, Wax, HPHT, remote desert locations and deep-water environments.

We can provide teams of HAZOP Chairmen managed by Theon, supported by Independent Process Engineers and Scribes working in parallel on large or fast track projects.

We cover all stages of projects from Concept, FEED, Detailed Design, design revalidation, pre-start up, and also subsequent modifications. Our Chairmen are approved by major blue-chip international operators.

Many of our HAZOP projects include HAZIDs, SIMOPs, SIL Assessments and LOPAs. We have experience in use of PHAPro, SIFPro and risk graph approach, and other proprietary packages to meet the client’s requirements.
