Introduction

A 3D Fire & Gas Mapping Study is a performance-based assessment used to evaluate and optimize the placement and effectiveness of fire and gas detection systems within complex Oil & Gas facilities.
Utilizing advanced 3D modelling and, where required, CFD-based dispersion and fire simulations, the study assesses detector coverage against credible hazard scenarios—ensuring that flammable gas, toxic releases, and fire events are reliably detected under realistic conditions.

Purpose

• Evaluate detection coverage for flammable gas, toxic gas, and fire scenarios
• Verify compliance with company standards and industry guidelines (e.g., coverage targets, voting logic)
• Identify gaps or blind spots in detector placement due to congestion or layout constraints
• Optimize detector locations and types (point, open-path, flame detectors)
• Support performance-based design using realistic dispersion and fire scenarios
• Enhance early detection capability to enable timely mitigation and shutdown

Outcomes

• Quantified detection coverage (e.g., % coverage for 1ooN / 2ooN scenarios)
• Identification of detection gaps and congested-area limitations
• Optimized detector layout and positioning in a 3D environment
• Recommendations for additional or relocated detectors
• Support for compliance with company and international standards
• Integration with dispersion studies and Fire & Gas philosophy
• 3D visualizations and structured report ensuring clarity and audit readiness
