Safety Case and Regulatory Assurance Services
We construct, challenge and defend technical safety arguments that regulators accept. Our work spans the full lifecycle, from modification and design substantiation through to independent assessment, legacy case remediation and regulatory submission strategy. The discipline is the same across every high-hazard sector; only the standards and acceptance criteria change.
Core engagements
- Independent Peer Review and Technical Assessment: An objective critical-friend review of engineering assumptions, safety cases and structural arguments before they reach a regulator.
- Fire, Explosion and Major Accident Hazard Assessment (Qualitative & Methodological): Qualitative HAZID, HAZOP, fault-tree and ALARP methodology for fire, explosion and major accident hazards, without CFD overhead.
- Modification and Design Substantiation: Discrete, rapid-turnaround safety arguments for plant modifications and engineering changes using documentation-driven logic.
