The conceptual stage is where the project’s risk profile is built and inherent safety flexibility is greatest — the FEL 2 package matures the fundamental safety decisions before that flexibility disappears.

• Preliminary Risk Register
• Technological Readiness Level Assessment Report
• Safety Engineering Implementation Plan
• Inherent Safety Review
• HAZID

FEED is where the design basis, key safety decisions and risk controls must reach the maturity EPC execution will be priced and committed on — the FEL 3 package carries the safety deliverables to that maturity.

• Process Safety Philosophy (Revised)
• Layout Safety Review (LSR1)
• Preliminary Flare Radiation and Dispersion Analysis
• HAC and Relevant Compliance Studies
• QRA/FRA
• Fire & Gas Conceptual Design (Philosophy, Mapping, C & E)
• Alarm Management Philosophy
• Functional Safety Management Plan
• Generic SIL Verification
• ToR and Project Based Philosophy Studies for All Safety Related Deliverables
• Functional Safety Assessment 1 (FSA1)
• Process Safety Requirements Specification (SRS)
• FEED Phase PHA (HAZOP, HAZID etc.)
• Target SIL Selection
• Updates of Consolidated Risk Register
• Passive Fire Protection Studies (Philosophy, Envelope, List of Equipment to be Fireproofed)
• Active Fire Fighting System Studies (System Concept, Preliminary Calculations, Technology and Equipment Selection)
• Data Sheet (DS) and Preliminary MR (Material Requisition)
