Course Description:

Attendees will learn how to perform Safety Integrity Level (SIL) Selection and Verification using the advanced capabilities of exSILentia® . This will help users determine the required risk reduction for each hazard scenario and the achieved risk reduction for each identified Safety Instrumented Function (SIF). The class will also cover interfacing with Process Hazard Analysis (PHA) results, documentation of the Safety Requirements Specification (SRS), and operational aspects such as proof testing.

Skills You Will Learn:

  • How to perform Safety Integrity Level (SIL) Selection and Verification using the advanced capabilities of exSILentia
  • Determine the required risk reduction for each hazard scenario and the achieved risk reduction for each identified Safety Instrumented Function (SIF)
  • Understand interfacing with Process Hazard Analysis results
  • Understand the documentation of the Safety Requirements Specification (SRS)
  • Understand operational aspects such as proof testing
  • Understand the impact of SIL verification parameters on the detailed design, implementation, and operation of the SIF

Course Topics:

Advanced features of exSILentia

  • Documenting IEC 61511 compliance
  • exSILentia structure (Projects, Safety Instrumented Functions)
  • Audit trail
  • SIL selection (SILect) (Specifying tolerable risk, Determining target SIL level)
  • SIF Safety Requirements Specification (SIF SRS)
  • SIL verification (SILver) (Determine Achieved SIL, SIL verification Details, SIF Parts/Group Options, selecting equipment from the SERH database, SIL verification support utilities)
  • Generating reports (Report option, Languages)
  • Software updates (Functionality Updates, Safety Equipment Reliability Handbook Updates)
  • SERH Viewer
  • PHA documentation (PHAX, PHA Import, Linking PHA items to SIFs and Alarms)
  • Alarm rationalization (SIL Alarm, Linking Alarms to IPLs)
  • Process and design safety requirements specification (Process SRS, Design SRS, Cause and Effect Matrix)
  • Proof test generator
  • Lifecycle cost estimator
  • Complete exSILentia SLC example
  • Complex SIL verifications
  • Conceptual Design – SIL verification exercise
