The operation of many industrial processes, especially those in the oil & gas industries, involve inherent risk due to the presence of dangerous gases. Safety Instrumented Systems are specifically designed to protect personnel, equipment, and the environment by reducing the likelihood or the impact severity of an identified emergency event. Explosions and fires account for millions of dollars of losses in the oil & gas industries each year. Since a great potential for loss exists, it is common for industry to employ Safety Instrumented Systems to provide safe isolation of flammable or potentially toxic material in the event of a fire or accidental release of fluids.

This course will explain the basic concepts, definitions and commonly used terms in Safety Instrumented Systems and Emergency Shutdowm, and provide a basic understanding of related concepts.

The course content is designed to provide the participant with an understanding of how to implement the requirements of the Safety Instrumented System standards, to perform layers of protection analysis, to create a design to meet the safety integrity level (SIL), and to verify that the SIL has been achieved. It will also introduce the participant to the guidance contained in draft technical report, ISA TR84.00.04, which concerns implementation of ANSI/ISA 84.00.01-2004.

Learning Objectives

 Upon the successful completion of this course, each participant will be able to:

  • Apply the latest technologies in Safety Instrumented Systems and Emergency Shutdown Systems
  • Emphasize the safety instrumented system management responsibilities and interpret the applicable safety standards  such  as  IEC 61508, IEC 61511,  ANSI/ISA S84.01
  • Identify the phases of the safety life cycle and be able to determine the safety requirement specification
  • Apply the various process hazard analysis namely the fault tree analysis, event tree analysis & FMEA and be able to heighten awareness on HAZOP study
  • Use a system approach on safety instrumented systems including its function & level and improve SIL determination using the ALARP method, semi quantitative methods, safety layer matrix method, risk graph method & LOPA Method
  • Acquire knowledge on SIL verification & validation using a structured approach and be able to review & improve SIS documentation
  • Apply proof testing on SIS & ESD in process industry and be able to conduct diagnostic procedures & partial valve stroking
  • Perform the process of selecting sensors, final elements & logic solvers and learn safety software models including their application
  • Employ the operation & maintenance of SIS & ESD following the guidelines & procedures on planning & implementation
  • Recognize the importance of SMART Safety Instrumented Systems including the intelligent field devices, digital communications, smart logic solvers & complete loop solution & be able to implement SMART SIS
