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.
This Service Hub is country-neutral. For India statutory CEng MIE deliverables or US PE-stamped deliverables, the country variants carry the full local stack.

For brownfield Gulf Coast refining majors in USA: process-safety engineering (HAZOP · QRA · LOPA · SIL) plus an Arc Flash AMC retainer that handles the 5-year recertification clock automatically.
From the Texas Gulf Coast to the Northern Virginia data-center corridor, the bundled risk + safety + AMC offer is what keeps the regulator audit cycle on schedule and the insurer at the table. The US Gulf Coast remains the densest concentration of brownfield refining, petrochem, and LNG capacity in the world. Add 14 GW of new data-center load committed by 2027 (Northern Virginia, Phoenix, Atlanta) and 50+ Tier-1 nuclear-adjacent OEM plants needing arc flash recertification on a 5-year clock under NFPA 70E 2024. New US refining capacity stopped being built in 1977. Petrochem expansion is brownfield debottlenecking. LNG capacity coming online uses existing brownfield port infrastructure. The 70E recertification clock and the data-center build-out are the two largest power-systems engineering markets in the country, and both are brownfield-first.
HAZOP follows IEC 61882; LOPA follows the AIChE CCPS guideline; SIL classification follows IEC 61511; QRA modelling uses the CCPS guidelines for consequence and frequency. Arc Flash AMC uses IEEE 1584-2018 against NFPA 70E 2024. Where the operator references NFPA 70E (Standard for Electrical Safety in the Workplace · 2024 edition) · IEEE 1584-2018 (Arc Flash Hazard Calculations) · NEC NFPA 70 · IEEE Color Books (399 Brown · 242 Buff · 141 Red · 142 Green · 493 Gold), the deliverable structure aligns; the methodology is invariant.
Frequency + consequence modelling for major hazard scenarios. Individual risk and societal risk contours where the operator boundary touches public land. The deliverable answers the regulator's "how safe is safe enough" question with a defensible number.
Independent protection layers documented; SIL requirements derived. The output feeds directly into the SIL assignment and the operator's safety-instrumented-function design or revalidation.
SIL classification per IEC 61511; SIL verification on the existing or proposed Safety Instrumented Functions using PFD and failure-rate data from the certified-equipment library. The deliverable closes the SIL-loop validation finding that most internal audits leave open.
Arc flash hazard calculation on the IEEE 1584-2018 method against NFPA 70E 2024. Labels printed in the USA-appropriate format. The arc flash baseline becomes the entry into the 5-year AMC retainer.
Annual walk-down + change-impact assessment + re-labelling on equipment changes + 5-year full recertification. The retainer turns the recertification cycle from a panicked sprint into a managed cadence. AMC contracts are signed for 3-, 5-, or 7-year terms.
Multi-disciplinary HAZOP led by a chartered facilitator. Deviation analysis at every node, cause-consequence-safeguard documented, recommendations ranked by priority. Where the USA regulator demands HAZOP at a specified cadence (a 5-year cycle is common), we structure the engagement to match the calendar.
Three US-Gulf-Coast and data-center engagements that show the working pattern:
a 350,000 BPD refinery with 138 kV intake and 1980s-vintage 4160 V switchgear lineups.
The engagement: Insurer FM Global demanded arc flash labels conforming to IEEE 1584-2018 (2002 method retired); incident energy on the FCC unit MCC exceeded 40 cal/cm² with existing fuse coordination.
a 12 MTPA LNG terminal with 13.8 kV electric-drive compressor train.
The engagement: Start-up coordination study identified misgraded relays on the cryogenic process boiler feed pump; cascading trip risk during first-fill resolved by adaptive setting groups.
a 60 MW Tier-IV hyperscale colocation with N+1 paralleled UPS.
The engagement: Uptime Institute Tier-IV concurrent maintainability proof required end-to-end arc flash study at every voltage level including 480 V PDU output; legacy 2014 study was on retired 1584-2002 method.
