Semi-quantitative risk evaluation of safeguard adequacy.
HAZOP identifies the deviation. LOPA quantifies whether the existing safeguards reduce the risk to tolerable. Where they don't · the gap is the Safety Integrity Level (SIL) required for the Safety Instrumented System. IEC 61511 compliant. The foundation for SIS design.
A HAZOP finding · 'high temperature in reactor R-101 leads to runaway exotherm' · doesn't automatically tell you whether the existing high-temperature trip is adequate. LOPA closes the gap. It assigns initiating event frequency, credits each independent protection layer (BPCS, alarms with operator response, mechanical relief, SIS), and arrives at a residual frequency that is either tolerable or not. If not, the residual frequency gap is the SIL required for the SIS. This semi-quantitative bridge between qualitative HAZOP and engineered SIS is what IEC 61511 mandates · we deliver it to the standard.
CEng MIE India-signed deliverables · LiDAR-powered where applicable · digital twin handover ready · routes to the Risk + Safety + AMC practice lead within 24 hours.
High-severity HAZOP findings extracted as LOPA scenarios. Initiating event + consequence + existing safeguards documented.
Industry-typical frequencies (CCPS, OREDA, your own incident history) assigned. Validated against operating experience.
Each IPL credited per IEC 61511 rules · BPCS (1 only), alarms with operator response (1 if procedure documented + tested), mechanical relief, SIS layers.
Residual frequency computed. Compared to your corporate / regulatory tolerable risk criteria. Gap quantifies SIL requirement.
SIL 0 / 1 / 2 / 3 allocated per scenario. CEng MIE-signed. Feeds directly into SIS specification.
Reports reference the international and national standards your regulators, F500 audit teams, and corporate process safety leads cite. Every deliverable signed by a Chartered Engineer (CEng MIE India).
Three anonymised engagements from our verified roster · quantified outcomes, no client names disclosed without written permission.
127 LOPA scenarios. 14 required SIS (mostly SIL 2). SIS gap closed in next turnaround.

A GCC pharma campus engaged the 5-year AMC retainer covering annual HAZOP refresh, arc flash recalculation under load growth, SIL recertification, OISD-equivalent safety audit support, and on-call Chartered Engineer access for incident response.
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.
IEC 61511 (process sector) + IEC 61508 (electronic / electrical / programmable electronic safety systems). LOPA is the primary SIL determination methodology, with risk graph as a screening tool. Fault tree analysis for SIL-3 systems and above.
Yes. OISD-118 (process plant safety), OISD-145 (Hazard Identification and Risk Analysis), OISD-153 (emergency response), PESO Petroleum Rules 2002, OSHA 1910.119 PSM, EPA RMP, and Factories Act statutory inspections are all in scope. Audit support is the most-used line item in the 5-year AMC retainer.
Single-unit HAZOP: 3 to 5 weeks. Full plant HAZOP refresh: 6 to 10 weeks. Arc flash study: 4 to 8 weeks. QRA: 6 to 10 weeks. LOPA + SIL: 4 to 6 weeks. Safety audit: 2 to 4 weeks. 5-year AMC retainer: 60 months with quarterly cadence reviews.
Yes. The 5-year AMC retainer is a fixed annual fee covering all routine deliverables (HAZOP refresh, arc flash recalc, SIL recert, audit support). Out-of-scope incident response or brownfield modification PSSR work is invoiced separately at retainer-discounted day rates.
Yes. The practice runs an integrated bench. HAZOP, QRA, LOPA and SIL on the process side. Arc flash, short-circuit, protection coordination and NFPA 70E / IS 13234 on the electrical side. Same Chartered Engineer leadership across both for refineries, pharma and data centres where the two regimes overlap.
