A Pune-based process-safety consultancy running the full PHA suite — HAZOP, HAZID, SIL, QRA and F&G mapping — across the project lifecycle, with a client footprint spanning the Middle East, Asia and Africa.

Indian EHS consultancy whose process-safety division facilitates HAZOP and other process-risk studies (PHA, LOPA, SIL, QRA, PSSR) with a multidisciplinary-team approach and refinery-sector clients — a fit for Indian operators wanting PHA facilitation within a broader safety practice.

Mumbai process- and chemical-engineering consultancy that conducts HAZOP studies and pressure-relief analysis as part of its process-safety work — a fit for Indian chemical and oil & gas operators who want HAZOP and PHA delivered alongside process-engineering support.

An oilfield engineering consultancy whose facilitators have chaired greenfield and brownfield PHA workshops for Gulf national oil companies — a fit for upstream and downstream operators wanting HAZOP facilitation embedded within a design-engineering house.

A Gujarat-based process safety firm that supplies its own HAZOP chairman and scribe and studies P&IDs across every stage of the plant life cycle, with a client base spanning Indian chemical, pharma and pesticide manufacturers and operators in the Middle East and Gulf — a fit for design-stage and revalidation HAZOPs on process plants in those sectors.

A North-India (Noida/Hyderabad) risk-management consultancy whose HAZOP studies are led by facilitators who pair design and process understanding with risk analysis — a fit for chemical, pharmaceutical and manufacturing operators wanting facilitator-led PHA alongside QRA and functional-safety support in one house.

A large environmental and engineering consultancy whose process-safety team has facilitated hundreds of PHAs — HAZOP, LOPA, FMEA and What-If — with remote or co-located facilitation, scribing, revalidation and QA/QC review, a fit for US and international operators wanting facilitation backed by a full PSM/RMP compliance practice.

A specialist risk-management consultancy (part of TUV Rheinland) with a large pool of client-approved HAZOP/PHA and LOPA chairs and proficient scribes, working from offices in the UK, Netherlands, Middle East (Doha, Dubai), Southeast Asia (Kuala Lumpur, Singapore) and North America — a fit for operators wanting facilitation from an established international bench across high-hazard industries.

One of the first Vietnamese-owned independent HSE consultancies, with a long published HAZOP project list for offshore operators and onshore plants — a fit for projects in Vietnam and the wider Mekong region needing local facilitators familiar with domestic operators and regulators.

Independent HAZOP/LOPA chairman working full-time as a facilitator since 2020, with a prior process-design career at Jacobs, Occidental and CCED Oman — a fit for operators who want a chair who has done the upstream design work, and for long-running facility revalidation HAZOPs measured in months rather than weeks.

Malaysian process safety house led by TÜV-certified functional safety engineers, pairing HAZOP facilitation with SIL work on offshore, FPSO/FLNG, and refinery assets.

Combines HAZOP facilitation with in-house, ISO/IEC 17025-accredited dust flammability and chemical reaction hazard (DSC/ARC) testing labs — useful when a study raises reactive- or explosion-hazard questions the team can't answer from the P&ID.

The global giant: multinationals standardizing HAZOP delivery across dozens of sites in different countries usually end up talking to DEKRA.
