Safety Integrity Level (SIL) Verification for the S84  / IEC 61511 Standard on Safety Instrumented Systems (SIS)

"I am armed and now dangerous."
- Scott Hansen, Invista

Course Description

ANSI/ISA S84.00.01-2004 / IEC 61511, Functional Safety: Safety Instrumented Systems for the Process Industry Sector requires that claimed Safety Integrity Levels (SILs) be verified by calculation. Calculation modeling methods are chosen based on the circumstances and include simplified equations, fault tree analysis and Markov modeling.

Factors that should be included in the modeling include:

  • Architecture

  • Technology

  • Field device configuration

  • Susceptibility to common cause failures

  • Component failure rates

  • Level of redundancy and voting

  • Proof tests and intervals

  • Diagnostics including reliability, test intervals and coverage

  • Repair times

  • Susceptibility to external influences

A detailed manual is provided for use as a reference after you have completed the course. Workshops are used to practice using the methods taught.

Target Audience

Process safety personnel, instrumentation engineers, reliability engineers and others who need to perform or understand SIL verification calculations.

Prerequisite

A degree in engineering or another technical discipline is required. Familiarity with control systems and experience in process safety is helpful.
