A SIL Verification exercise to confirm the compliance of x2 Safety Instrumented Functions for a chemical project. Reviewing the compliance of the SIF components, checking that the correct hardware fault tolerance had been selected and generating the PFD calculations.

Project is to determine whether the Probability of Failure on Demand (PFD) for an installed SIS meets the target PFD of 0.1 presented in the LOPA review. The PFD calculated for the SIF was then incorporated into an update to the LOPA.

Project to carry out a Safety Instrumented Function (SIF) Safety Integrity Level (SIL) and Probability of Failure on Demand (PFD) Calculation Verification on four SIFs.

Project to investigate client's approach to HAZOP, LOPA and PFD Calculation where multiple SIFs protect a single hazard. Confirm whether approach CCF used is in line with current best practice.

Project to carry out SIL Verification and confirmation of PFD calculations for x22 SIF's.

An update to an earlier SIL verification and PFD calculation exercise.

For an oil storage facility, carrying out an exercise to confirm that the SIL requirement was correct (under review changed from SIL 1 to SIL 2), identify a replacement for non-compliant contractor and confirm the compliance of a non-certified galvanic isolator by way of a prior use analysis.

A "SIL Verification" exercise to confirm the compliance of x6 Safety Instrumented Functions for a Boiler package vendor. Reviewing the design against the SRS, confirming compliance of the SIF components, checking that the correct hardware fault tolerance had been selected and that the PFD calculations were correct.
