Design & Operation of a Safety Instrumented System (SIS) - Remote training


Who should attend?

  • Understand how a risk can be reduced by an instrumented safety barrier.
Public :
  • Engineers and technical staff involved in design of SIS.

Level : Proficiency

Course Content


      • Different safety instrumented systems: PSS, ESD, F&G, HIPS, ESP.
      • Links between the different SIS - Global architecture.
      • Control loop: basic knowledge; elements constituting a SIS.

      • Use of safety reviews (HAZOP & LOPA & HAZOP) to determine the need for a Safety Instrumented Function (SIF).
      • Concept of independent protective layers.
      • Use of a risk matrix to determine the level of SIL required for each RIS.

      • Role of functional analysis.
      • FIS allocation, cause and effect matrix, redundancy and common mode.
      • Typical design.
      • Simple SIL calculations. Analysis of supplier documentation.
      • SIL level and frequency of testing.

Learning Objectives

  • Upon completion of the course, participants will be able to:
  • determine the Safety Integrity Level (SIL) of a simple system,
  • identify the need to implement a Safety Instrumented System (SIS),
  • apply knowledge of the main topics of the IEC61511 standard methodology to design a SIS system.

Ways & Means

  • Step by step case study.
  • Study of SIS on mini processes test benches.
