Bow-Tie analysis in Europe

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.

Small UK/US technical-safety and engineering-modelling consultancy that pairs HAZOP facilitation with in-house consequence and reliability modelling — a fit for upstream oil and gas and CO2 projects needing PHAs for OSHA PSM alongside safety cases, SIL allocation and quantitative follow-on work.

A UK multi-disciplinary engineering, risk and compliance provider offering HAZID, HAZOP and FMEA facilitation, a fit for high-risk industrial sites wanting a senior-led team for process and electrical HAZOP studies alongside DSEAR and ATEX support.

A Cyprus-based specialist consultancy in process safety, major hazards and HSE for the energy sector, offering HAZOP/HAZID facilitation alongside QRA, safety-case development and barrier management, a fit for offshore and onshore operators needing regulator-ready major-hazard deliverables.

A Dutch HSEQ and process-safety consultancy whose specialists lead group hazard-identification studies — HAZOP, HAZID, LOPA, bow-tie, SIL and FMECA — for the oil, gas, chemical, tank-storage and wind sectors.

A France-based engineering house serving oil & gas operators (with Algerian operations) that assigns HAZID, HAZOP and SIL facilitators, backed by QRA and bow-tie analysis and its EPC365 safety-management platform.

Spanish process-safety boutique offering HAZOP studies in Spanish and English alongside SIL and LOPA work to IEC 61508/61511 — a fit for Iberian and international oil & gas, chemical and pharmaceutical operators wanting PHA that feeds into functional safety.

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.
