Hazard Studies & Risk Assessment

Escape, Evacuation & Rescue Analysis (EERA)

Quantified evacuation feasibility for offshore, onshore, and high-rise facilities

What this study delivers

Escape, Evacuation &
Rescue Analysis (EERA)

EERA quantifies the feasibility and timing of personnel escape, evacuation, and rescue under credible major accident scenarios. Particularly critical for offshore installations, EERA validates routes, equipment, and timing against the developing hazard envelope.

Escape, Evacuation & Rescue Analysis (EERA) — Overview
Study execution

How the study is executed

A structured, facilitated process — from scope definition through close-out — producing defensible, actionable outputs.

Offshore EERA Scope & Regulatory Brief

Define EERA scope per PFEER (Prevention of Fire and Explosion, and Emergency Response, Regulations 1995 — UK), NORSOK Z-013, SOLAS / IMO MODU code; align with HSE Offshore Safety Case and CCPS Offshore guidance.

DSHA & Escape Route Audit

Identify Design and Safety-related Hazardous Activities (DSHA) and credible-worst-case events; audit escape routes for redundancy (minimum 2 routes), survivability (PFP rating, smoke control), and accessibility (mobility-impaired, injured).

TR (Temporary Refuge) Performance Standards

Establish TR performance standards per PFEER — smoke / toxic gas integrity (overpressure ventilation), thermal integrity (PFP rating), structural integrity (blast resistance), endurance (typically 1-2 hours per scenario).

Evacuation System Assessment

Assess evacuation systems — primary (TEMPSC lifeboats per SOLAS, free-fall lifeboats per MODU code), secondary (life rafts, sea-jump), tertiary (helicopter); specify launch / retrieval testing per PFEER.

Rescue & Recovery Capability

Assess rescue capability — Standby Vessel per OPITO (UK), Fast Rescue Craft (FRC), helicopter SAR coverage; specify recovery to safe haven (typically <2 hours) and medical capability (TR + onshore receiving hospital).

EERA Documentation & Drill Validation

Compile EERA report with hazard scenarios, TR performance, evacuation system assessment, rescue capability; specify drill programme per PFEER Regulation 16; align with Offshore Safety Case and HSE inspection.

Why it matters

Outcomes of Escape, Evacuation & Rescue Analysis (EERA)

Offshore EERA Survivability Assurance
  • Validates personnel can escape credible scenarios
  • Identifies route bottlenecks and equipment gaps
  • Reinforces TR survivability under fire/explosion
  • Improves rescue planning realism
PFEER / SOLAS / IMO EERA Defence
  • Satisfies NORSOK S-001 and UK PFEER
  • Supports IMO LSA Code compliance
  • Documents EERA for safety case
  • Maps to API RP 14J for offshore
TR & Evacuation System Reliability
  • Drives realistic evacuation drill design
  • Improves crew familiarisation
  • Supports standby vessel positioning
  • Tightens emergency response timing
EERA-Driven Capex Targeting Value
  • Targets LSA upgrades to identified gaps
  • Reduces over-specification of unused equipment
  • Avoids regulatory non-compliance findings
  • Supports insurance underwriting dialogue
