Risk + Safety + AMC

Permit-to-Work Systems

Q: How long does a typical HAZOP take?

A small unit (< 200 P&ID line items): 3-5 days workshop + 4-6 weeks reporting. A full refinery process unit: 2-4 weeks workshop + 8-10 weeks reporting. Cycle time depends heavily on P&ID readiness.

Q: What's the link to SIL and LOPA?

HAZOP identifies hazardous deviations + raises safeguard recommendations. Where safeguards are insufficient, SIL/LOPA quantifies the risk gap and sizes the Safety Instrumented System (SIS) needed to close it.

Q: Do you handle re-HAZOP only, or first-time HAZOP for new units?

Both. First-time HAZOP is typically done at 90% engineering design (before procurement). Re-HAZOP is done every 5 years and after any major MOC. Our chair pool covers both.

Q: Will you also handle the recommendation closure tracking?

Yes · we offer recommendation tracking as part of the 5-year Safety AMC retainer. Quarterly review of open items + escalation to plant safety committee. Critical for actually closing the recommendations, not just raising them.

Process hazard analysis · structured deviation review of every node.

Guideword-driven, node-by-node, deviation-by-deviation. HAZOP led by a CEng MIE India-qualified chair, supported by your operations and process engineering team. IEC 61882 compliant. Recommendations tracked to closure. The foundation for SIL and LOPA.

Why this matters

Why HAZOP can't be done from drawings alone · and why most third-party reports miss this

A good HAZOP requires more than a credentialled chair and a copy of IEC 61882. It requires P&IDs that match field reality (most don't), a knowledge of your operating procedures (most third-party chairs don't), and a discipline of capturing recommendations that survive into closure (most reports don't). Our HAZOP delivery is structurally different · we update the P&IDs first if needed, the chair reads the operating procedures before the workshop, recommendations track to closure with named owner and date. The output is not a 200-page PDF that gets filed; it's a recommendation register that drives real change.

Method

How we deliver Permit-to-Work Systems

CEng MIE India-signed deliverables · LiDAR-powered where applicable · digital twin handover ready · routes to the Risk + Safety + AMC practice lead within 24 hours.

Pre-workshop · P&ID + ops procedure review

P&IDs verified against field. Operating procedures, alarm rationalisation, SIS philosophy reviewed by HAZOP chair.

Workshop facilitation

Node-by-node, guideword-driven (more, less, none, reverse, as well as, part of, other than). Causes, consequences, safeguards captured. Recommendations raised.

Recommendation review

Each recommendation reviewed for actionability, owner, target date. Recommendations escalated to SIL / LOPA as appropriate.

Report + closure tracking

IEC 61882-compliant report. Recommendation register linked to your action tracking system (PHA-Pro, Plant Doctor, your CMMS).

Sign-off + governance

CEng MIE-signed. Re-HAZOP triggered by MOC, every 5 years per standard, or on any significant incident.

Standards + compliance

Built to the standards your auditors quote

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).
