Escape, Evacuation Rescue Analysis (EERA) for Drilling Platform

Escape Evacuation Rescue Analysis (EERA) was carried out for an offshore drilling platform as part of a field development project to evaluate the effectiveness of emergency response systems under credible major accident scenarios.

This EERA study focuses on ensuring that all personnel can safely escape from hazardous areas, reach protected muster locations, and be evacuated from the installation within acceptable time limits, even under severe emergency conditions.

Project Overview

• Facility: Drilling Platform
• Study Type: Escape, Evacuation & Rescue Analysis (EERA)
• Objective: Evaluate emergency evacuation, escape, and rescue effectiveness

Why EERA is Critical for Offshore Safety

Escape, Evacuation and Rescue Analysis (EERA) is a key component of offshore safety engineering. It ensures that facilities are designed and operated to protect personnel during events such as fire, explosion, or toxic gas release.

An effective EERA study helps:

• Minimize risk to personnel
• Improve emergency response planning
• Ensure compliance with international safety standards
• Enhance overall facility safety and preparedness

Objectives of the EERA Study

The primary objective of this EERA assessment is to verify that the platform’s emergency systems can achieve the following:

• Rapid detection of incidents and alarm initiation
• Safe escape from incident locations to muster areas
• Availability of protected and accessible muster stations
• Efficient evacuation from the offshore installation
• Reliable rescue and recovery arrangements
• Temporary Refuge (TR) integrity to support personnel until evacuation

Methodology

A structured, scenario-based approach was adopted to perform the Escape, Evacuation & Rescue Analysis.

Identification of Major Accident Hazards (MAHs)

The following credible emergency scenarios were evaluated:

• Jet fire scenarios
• Pool fire incidents
• Flammable gas releases (LFL conditions)
• Toxic gas release scenarios

Goal Based Assessment

Each identified hazard scenario was assessed against key EERA performance goals to evaluate potential impacts on:

• Escape routes and access paths
• Muster area safety and accessibility
• Evacuation systems and arrangements
• Rescue and recovery strategies
• Temporary Refuge survivability

Escape & Evacuation Analysis

The escape and evacuation assessment included:

• Travel distance analysis from work areas to muster stations
• Availability and redundancy of escape routes
• Impact of heat radiation, smoke, and gas dispersion
• Adequacy of escape route design, signage, and lighting

Mustering Analysis

The mustering assessment evaluated:

• Capacity of muster areas versus maximum personnel onboard (POB)
• Protection against fire, smoke, and hazardous gas exposure
• Accessibility from all operational areas
• Suitability of muster areas to function as Temporary Refuge

Evacuation & Rescue Assessment

The evacuation and rescue systems were analyzed based on:

• Availability and capacity of lifeboats and life rafts
• Redundancy and reliability of evacuation systems
• Emergency launching arrangements under adverse conditions
• Rescue and recovery philosophy

Time Based Evacuation Analysis

A detailed time-based analysis was conducted to ensure that:

• Emergency detection and alarm systems respond promptly
• Personnel can safely reach muster areas within defined time
• Mustering and preparation are completed efficiently
• Full evacuation can be achieved within acceptable limits

Evacuation timelines were benchmarked against hazard escalation scenarios to confirm safety margins.

Codes & Standards

The EERA study was conducted in accordance with internationally recognized guidelines and standards:

• DNV Guidelines for Offshore Quantitative Risk Assessment
• SOLAS (Safety of Life at Sea) Convention
• NFPA 101 – Life Safety Code
• API RP 14J – Design and Hazard Analysis for Offshore Facilities
• Human Factors Engineering Standards (Workspace Design)

Key Findings

The EERA study demonstrates that:

• Emergency detection, escape, and evacuation objectives are largely achieved
• Escape route impairment may occur in certain fire and gas scenarios; however, alternate routes are available
• Muster areas have sufficient capacity and protection for maximum personnel onboard
• Evacuation systems provide adequate redundancy and reliability
• Personnel can be safely evacuated within acceptable time limits

Identified improvement areas were addressed with recommendations to further enhance emergency preparedness and personnel safety.
