Quantitative consequence + frequency analysis for plot plan and siting decisions.
Where do you locate the new control room relative to the cracker? What's the safe separation between the LNG tank and the road? Is the existing fire-water capacity adequate for the worst case? QRA quantifies it · consequence modelling, dispersion analysis, individual + societal risk contours. F&EI, PHAST, FLACS as the engine. Decision-grade evidence.
HAZOP and LOPA tell you whether process safeguards are adequate. QRA tells you what happens when they fail · the dispersion footprint of an LNG release, the thermal radiation contour of a jet fire, the overpressure profile of a VCE. These results drive plot plan decisions (control room siting, building separation, mustering point location), siting decisions (LNG terminal next to residential? Refinery boundary clearance?), and capex justification (fire-water capacity, blast-resistant building envelope). QRA is the decision-grade quantitative tool that makes these conversations evidence-based.

Client name withheld · representative of multiple engagements in this category
Annual HAZOP refresh, arc flash recalculation when load grows above 8% or topology changes, SIL recertification at year 3, OISD / PESO / OSHA audit support, on-call Chartered Engineer access for incident response (24-hour SLA), and pre-startup safety review chairing for any in-period brownfield modification.
IEEE 1584-2018 for arc flash incident energy calculation, NFPA 70E (2024) for the workplace electrical safety requirements and warning label format, IS 13234 for India statutory equivalent, and IEC 61482 for arc-rated PPE selection. Calculations validated against the ETAP power system model.
Yes. India HAZOPs chaired by a staff CEng MIE India. US OSHA PSM Process Hazard Analyses chaired through the Houston entity by a PE-credentialed safety lead. International (GCC + EU + AUS) engagements chaired by a CEng who carries the equivalent local recognition.
