IS 13234 (arc flash), IS 14489 (HAZOP guideline), OISD-STD-129 (process safety management), OISD-STD-144 (QRA), OISD-GDN-180 (HAZOP and LOPA framework), OISD-STD-116 (fire protection), PESO requirements for hazardous-area facilities, Factories Act 1948 with state-specific Rules, CEA Regulations 2010 and DGMS for mining.
Yes. Every HAZOP report, QRA, LOPA workshop output, SIL verification, safety audit and AMC deliverable carries a Chartered Engineer (CEng MIE India) signature from a full-time staff Chartered Engineer registered with the Institution of Engineers (India).
Recurring HAZOP refresh on the agreed cycle (typically 5 years per OISD-GDN-180), IS 13234 arc flash recertification every 5 years, PESO licence renewal support, OISD audit pack maintenance, Factories Inspectorate audit support, and LOPA / SIL re-verification where modifications occur. Optional incident investigation included.
PHAST and SAFETI for consequence and risk modelling. FRED for free-field thermal radiation. exSILentia for SIL determination and PFD verification. PHA-Pro and HAZOP Manager for HAZOP recording. Aligned to OISD-STD-144 and ISO 17776 frameworks.
Yes. Our safety study deliverables are structured to clear PESO (Petroleum and Explosives Safety Organisation), OISD (Oil Industry Safety Directorate), DGMS (Directorate General of Mines Safety) and Factories Inspectorate audits without supplementary documentation. CEIG and Electrical Inspectorate audit support included.
IS 13234 (aligned to IEEE 1584-2018) recommends arc flash review every 5 years or after major electrical modifications. Factories Inspectorates increasingly cite arc flash as part of routine safety audits. The 5-year AMC retainer covers IS 13234 recertification along with PESO renewals and Factories Act audit packs.
1 to 14 weeks depending on scope. HAZOP for a process unit: 1 to 3 weeks of workshop plus 4 weeks report. QRA for a refinery: 8 to 14 weeks. SIL determination workshop: 1 to 2 weeks. Safety audit: 1 to 2 weeks. AMC retainer: rolling 5-year engagement. Site mobilisation typically 72 hours from Hyderabad HQ.
Yes. Threat + barrier + consequence mapping for major accident hazards is delivered in BowTieXP or similar. Aligned to OISD-GDN-180 framework and integrated with HAZOP, LOPA and SIL findings. Plant safety case format on request.
