Fire and gas detector mapping studies gives an objective analysis of detector layouts to support the design method and optimize the amount of detectors required to satisfy coverage targets.
Major oil corporations extended ‘ISA TR84.00.07 steering on the Effectiveness of fireside and Gas Detection’ to handle the logic question of “How several detectors is needed in dangerous facility & wherever to position it all?”
F&G mapping study ought to be conducted within the style stage to assure that the detector coverage targets square measure met and also the current F&G arrangement is effective to satisfy its supposed designed perform.
Moreover, throughout the traditional operation, the F&G mapping study ought to be performed once major changes or modifications square measure applied to the facilities. As a result, the study shall make sure whether or not this arrangement remained appropriate for continuous in operation. If it's not the case, a collection of recommendations shall be provided and regarded to enhance the FGS performance.
A 3D simulation software (e.g Detect 3D) is usually used to perform this F&G mapping study take into account the obstruction of equipment, structure. A F&G mapping study is especially supported by the comparison of detector coverage versus the coverage target.
Detector Geographic Coverage – is generally defined as the fraction of the geometric area of a defined monitored process area that would be detected by the detector considering the defined voting arrangement (if a release were to occur) in a given geographic location.
Detector (Scenario) Coverage – For each defined release scenario, a part of gas dispersion is outlined. Detector Scenario Coverage is defined as the fraction of the area that can be detected by the detector considering the defined voting arrangement in the area of gas dispersion.

A typical F&G mapping study is conducted as per the following steps:
