QRA in UK

London-headquartered engineering consultancy with a long-running HAZOP/LOPA programme for Middle East operators — it states more than 750 project HAZOP/LOPA workshops for Saudi Aramco and more than 500 design reviews and HAZOPs for PDO — a fit for operators wanting facilitated baseline studies and revalidations of large refining, gas and petrochemical facilities.

A Netherlands-based independent Technical Safety Engineer and HAZOP facilitator who chairs and scribes HAZOP studies across offshore oil & gas and offshore renewables, including offshore substations — a fit for operators in the Netherlands, UK and wider North Sea region wanting an independent chair for offshore energy and energy-transition projects.

A London-based functional- and technical-safety consultancy that supplies both facilitator and scribe for HAZOP and CHAZOP studies, with TUV Rheinland certified Functional Safety Engineers, a fit for end users, EPCs and integrators wanting facilitation linked through to SIL classification and verification.

A UK process- and functional-safety consultancy weighted toward energy-transition projects — a fit when a HAZOP sits alongside hydrogen, carbon-capture, renewables or nuclear scope and needs the wider PHA suite (HAZID, LOPA, SIL, QRA) around it.

An employee-owned safety-engineering and risk-management consultancy with offices across the UK and Australia, offering HAZOP and facilitation alongside safety-case, functional-safety and QRA work — a fit for high-hazard operators in oil & gas, nuclear, defence and rail.

A UK technical-safety practice offering experienced HAZID, HAZOP, LOPA and SIL facilitators and secretaries with full study coordination and project management; its facilitator services have been audited and approved by a number of major oil & gas operators and EPC contractors.

Welsh electrical and functional-safety engineering firm whose TÜV-certified SIS engineers lead HAZID/HAZOP studies and integrate with client process-engineering teams, either standalone or as part of a QRA — a fit for UK process operators wanting HAZOP tied to safety-instrumented-system design.

A UK functional-safety specialist (IEC 61508 / 61511) whose HAZOP studies are led by several experienced, operator-approved HAZOP chairs and recorded in its own ProSET PHAComp software — a fit for onshore and offshore projects that need PHA joined up with SIL determination and verification.

A Nigerian process- and loss-prevention engineering firm based in Warri offering HAZOP/PHA facilitation alongside SIL, LOPA, HAZID and QRA work — one of the few options for operators wanting facilitation sourced from within the Niger Delta industrial belt.

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.
