HAZOP Consultants for Power, energy & renewables in North America

An Alberta multi-discipline engineering consultancy listing PHA and HAZOP facilitation within its process-engineering practice, a fit for operators wanting hazard-study facilitation from a firm that also carries the process design work.

An executive and project consultancy for the mining, energy and infrastructure sectors offering independent, third-party HAZOP review facilitation, a fit for project owners wanting a neutral facilitator to lead HAZOP and design reviews across the project lifecycle.

A Houston fire, risk and process safety consultancy offering process hazard analysis facilitation alongside fire and explosion modelling, a fit for oil, gas, LNG and power operators wanting HAZOP/PHA facilitation combined with consequence modelling, LOPA and SIL work.

A Newfoundland engineering consultancy that supplies expert leadership, facilitation and software for HAZID, HAZOP, PHA, LOPA and scenario-based risk assessments, a fit for onshore and offshore energy, mining and utilities operators in Atlantic Canada wanting facilitation alongside technical and process-safety engineering.

A California-based process safety and environmental boutique offering HAZOP/LOPA facilitation with strong US regulatory coverage (EPA RMP, OSHA PSM, CalARP) — a fit for domestic operators needing PHA delivered inside a compliance program.

A principal-led Colorado process-engineering practice offering HAZOP and PHA facilitation and documentation as part of senior, PE-stamped support for regulated industrial projects — a fit for owners and EPCs needing on-demand process-safety facilitation.

A US process-safety consultancy whose FidelisCore team provides experienced, independent PHA facilitators for HAZOP, What-If and LOPA studies across refining, petrochemical, hydrogen and LNG operations — a fit for OSHA PSM-covered operators needing initial PHAs, five-year revalidations or MOC-triggered studies led by an independent chair.

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.

A US process-safety consultancy focused on PHA/HAZOP facilitation and SIL/LOPA verification for petroleum and energy operators, offering either a combined lead-and-scribe facilitator or a separate scribe, and fluent in PHA-Pro and PHAWorks documentation.

A Canadian process-safety boutique focused on chairing and facilitating PHA sessions — HAZOP, HAZAN, HAZID, What-If, LOPA and SIL — that travels to client sites worldwide, with a sideline in PHA methodology and PHA-Pro software training for oil & gas, chemical, petrochemical and mining operators.

Bogotá-based process-risk consultancy delivering HAZOP studies in Spanish across Latin America, with a US office in Florida and its own PHA and bow-tie software — a local-language option for Colombian and wider Latin American chemical, petrochemical and oil & gas operators, and the directory's first Colombian firm.

Calgary process- and functional-safety boutique whose named principals hold CFSE and TÜV Rheinland functional safety credentials — a fit for Canadian and US operators wanting PHA facilitation joined up with SIS/SIL lifecycle, alarm management and fire & gas work under CSA Z767 and IEC 61511.

Calgary-based facilitator that has run thousands of HAZOPs for Canadian and international oil & gas operators, documenting studies live in PHA-Pro — a fit for greenfield and revalidation studies across energy, power and process assets.

The explosion- and dust-hazard specialist and developer of the FLACS CFD software — its HAZOP teams pair facilitation with deep consequence modelling, strong when the study touches gas or dust explosion risk or energy-transition fuels like hydrogen, LNG, ammonia and CCUS.

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.

Boutique PHA specialist that will assemble the full study team — facilitator, scribe, and subject-matter experts — rather than just parachuting in a chair.

The data-driven outlier: pairs PHA facilitation with analytics run over thousands of past studies, so your HAZOP gets benchmarked rather than filed.

Instrumented-safeguards specialists — a good chair when the study's real question is whether the interlocks and fire-and-gas coverage actually close the risk gap.

Global scale with offshore and marine depth — a frequent choice for FPSO, terminal, and offshore-platform HAZOP/HAZID campaigns.

The classification-society pedigree plus early depth in hydrogen and new-energy safety — relevant as HAZOP demand shifts toward energy-transition projects.

Houston-based with genuine international reach — a frequent facilitator for Middle East mega-project HAZOP campaigns.
