Design and Operation of a Safety Instrumented System (SIS)

Introduction

This training course ” Design and Operation of a Safety Instrumented System (SIS) ” has been designed to introduce participants to the design considerations and expose them to relevant information needed to properly select an SIS.

Participants will understanding the process in choosing the technology that fits to the plant and installation, testing of the SIS.

Safety Instrumented Systems (SIS) by definition is the instrumentation installed in a facility for the purpose of taking the process or specific piece of equipment in the process to a safe state. The SIS is designed to respond to plant emergency situations and generate the correct output before a hazardous event takes place. The SIS requires planning and is designed to the particular characteristics of the facility. SIS is designed to integrate plant shutdown systems such as the Emergency Shutdown Devices (ESD) and Plant Shutdown Devices (PSD) systems. Once the SIS requirements are determined, the appropriate technology is chosen and the SIS is installed and tested for functionality and operability. Once the facility is operating, the SIS must be maintained and checked at regular intervals.
