By the time detailed design starts, 80% of the safety-relevant design decisions are locked in. FEED is where we earn our keep.
FEED establishes the P&IDs, the instrumentation philosophy, the relief system approach, the control narrative, and the safeguard strategy. All of these lock in during FEED — and changing them after FEED is expensive. SafeGuard Projects embeds into FEED as the process safety voice.
Many projects schedule their first HAZOP at the IFC P&ID stage. By then, the HAZOP can document hazards but can rarely fix them economically. A FEED-stage HAZOP on developing P&IDs costs less and changes more.
P&ID-level HAZOP on developing P&IDs. Issue-by-issue review as P&IDs advance. Action register maintained through FEED phase. Re-HAZOP of significantly revised nodes.
Layer of protection analysis for HAZOP-identified scenarios. SIL targets assigned per IEC 61511. SIS conceptual design review. Proof test interval recommendations.
Safety instrumented system (SIS) philosophy. Alarm philosophy development (IEC 62682 compliant). Relief system philosophy. Fire and gas system philosophy.
PSI compilation: chemical data, P&IDs, equipment design data, relief design basis. PSM §(d) compliance documentation. Maintained throughout FEED as design advances.
Vapor dispersion for toxic and flammable releases. Fire and explosion modeling for facility layout decisions. Blast overpressure for occupied building siting. Setback distance recommendations.
All 14 PSM elements mapped to FEED, detailed engineering, and startup milestones. Gap analysis against 29 CFR 1910.119. Timeline for program element completion.
This is the moment. Let's talk about what your P&IDs need before they're issued for construction.
