Design & Operation of a Safety Instrumented System (SIS)

3 days SEC/SIS-E
Level
Proficiency
Audience
  • Engineers and technical staff involved in design, operation and maintenance of SIS.
Purpose
  • Ensure that design, operation and maintenance of a SIS will meet the expected risk reduction.
Learning Objectives
  • To specify the expected risk reduction factor.
  • To understand the Safety Integrity Level (SIL) concept.
  • To use the IEC 61511 methodology for design and operation.
Prerequisite
  • Basic knowledge in safety and instrumentation.
Ways and means
  • Step by step case study.
  • Case studies occurred in industrial plants.
  • Proactive teaching methodologies and numerous exercises.

SIS AND INDUSTRIAL RISK MANAGEMENT 0.75 day
  • Identification of required Safety Instrumented Function (SIF) with Safety Reviews (LOPA & HAZOP).
  • Concept of Independent Protection Layer (IPL).
  • Determination of required Safety Integrity Level (SIL) using a Risk Matrix.
SIS DESIGN 1.5 days
  • Functional Specification: SIF allocation, cause/effect matrix, functional analysis, redundancies and fault tolerance requirements according to SIL.
  • System Specification: Safety Programmable Logic Controller (S-PLC), Man Machine Interface (MMI).
  • Software specification: voting, maintenance bypasses and sensor signal analysis. Actuators discrepancy management.
  • Hardware specification: recommended technologies for sensors and actuators.
  • SIS Validation: required documents; Factory and Site Acceptance Tests (FAT - SAT).
SIS OPERATION 0.75 day
  • Management of bypasses and changes.
  • Definition, implementation and optimization of inspection and test program.
MINI-PROJECT
  • Step by step application of IEC methodology to a small process unit:
  • risk and IPL analysis
  • SIS specification
  • test definition including periodicity
  • test procedure validation.
