Performance-Based Fire and Gas Mapping Software
Fire and gas system design has historically been a challenge. The design of systems was based on inconsistent rules of thumb that resulted in widely varying requirements for similar facilities. In an effort to formalize and standardize the process for designing fire and gas systems, industry experts, including the pioneers at Kenexis, developed the ISA 84.00.07 Technical Report. This built on the performance-based quantitative approaches of the IEC 61511 standard, including safety integrity level (SIL) and added requirements specific to fire and gas detection arrays, notably coverage requirements.
Since the release of this technical report, most sophisticated process industry companies have incorporated the concept of achieving quantitative coverage targets into their fire and gas design processes. With the advent of fire and gas mapping for coverage targets using sophisticated computerized tools, such as Kenexis Effigy™, process safety has taken a step forward.
As part of the original team of experts that developed the techniques described in the ISA 84.00.07 Technical Report, Kenexis was charged with developing the software that would perform calculations based on the metrics that the technical report defined. Through several years of research and extensive validation, Kenexis developed an unparalleled software solution that performs coverage calculations with a degree of sophistication and accuracy unrivaled by any other software or method.
