Analysis of an existing fire detector system

A principal objective of a fire and gas system design is to reliably detect, alarm, and, if necessary, take automatic action to mitigate a fire hazard, combustible gas hazard, or toxic hazard.

The ability of the system to perform its intended safety actions in a demand condition is dependent on a number of factors associated with design, installation, site-specific operating conditions, and maintenance.

This article presents a case study of the analysis of an existing fire detector system in the Gulf of Mexico. The analysis demonstrates that better coverage could be obtained using fewer detectors and allowing the design to be changed, resulting in significantly lower maintenance costs while improving safety.

 

Take note

  • Fire protection systems require optimal fire detection systems.
  • With proper design, fire detection systems that use fewer detectors can be demonstrated to offer better coverage than many existing systems.
  • By employing risk based fire and gas system analysis, overall system design can be significantly improved.
