The calculation is performed using a SIS-TECH proprietary software tool, SIL Solver ®, or Isograph FaultTree+, depending on the complexity of the safety function.ĭatabases: The SIS-TECH proprietary database provides failure rate data and other reliability parameters. Software: Fault tree analysis is used to calculate the PFDavg and the spurious trip rate of each safety function.

Methodology: Verification is performed by modeling each SIF using fault tree analysis, which is a highly adaptable logic diagram based technique. Spurious trips have a significant impact on production and cost, so our design and verification process also analyzes the spurious operation rate and optimizes the design to achieve the best overall lifecycle cost. The Safety Integrity Level (SIL) or the average probability to fail on demand (PFDavg) of each safety instrumented function (SIF) is calculated to verify that each SIF achieves the risk reduction allocated during the hazards identification and risk analysis.
