Fire and Gas Mapping Study

Expand / Collapse

BC proposes a detailed fire and gas mapping study using advanced computational tools capable of accounting for complex geometries.

The methodology ensures the most cost-effective solution while maximizing detection coverage.

Flame detection and fire mapping

A tool and methodology with powerful ray-casting algorithms to accurately determine the obstructed Field Of View (FOV) of flame detectors is used. Using the data from thousands of rays cast from each detector, a full 3D representation of coverage areas is built, which can be visualized using contours or isovolumes.​

Gas detection and gas mapping

The proposed gas mapping analysis is a risk-based approach developed by conducting Computational Fluid Dynamics (CFD) simulations. The method requires the execution of the following three (3) tasks:

  • Leak frequencies are assigned to hazardous release scenarios as well as wind rose probability data. A matrix of simulations is generated by taking into account the combination of all cases with their associated frequencies and probabilities.

  • Risk-based visualizations are generated; e.g., analysis of exceedance of gas concentrations displayed with contours or isosurfaces.

  • Different layouts are generated with the aim to compare performance target and alarm settings.

Physical Barriers Sensitivity Analysis

Expand / Collapse

BC analyzes the effectiveness of passive protection layers intended to mitigate impacts once the hazardous Loss of Containment (LOC) scenario occurred. The sensitivity analysis accounts for complex geometries, and it is intended to:

  • Model shielding from hazards and/or consequences

  • Confirm which is the most cost-effective solution able to provide time for the response team to activate and for evacuation of personnel to a safe location.

Examples of passive protection layers are blast walls /fire walls, bunds/dikes, trees, building, flame/detonation arresters, etc.

Generic physical barriers to be considered are the following:

  • Toxic/Flammable Gas, barrier which is intended to physically reduce the impacts of toxic/flammable gas dispersions being located between the source term point and the target location to be protected.

  • Flame Protection, barrier which is intended to physically reduce the impacts of flame impingement being located between the source term point and the target location to be protected.

  • Flux Protection, barrier which is intended to physically reduce the impacts of harmful radiation from fires being located between the source term point and the target location to be protected.

  • Blast Protection, barrier which is intended to physically reduce the impacts of harmful overpressure/impulse from explosions being located between the source term point and the target location to be protected.
