Safety Instrumented Systems & Emergency Shutdown

Functional process safety involves identifying potential hazardous events that can trigger a chain reaction that could lead to severe or catastrophic consequences. This training explains the requirements of the international standards IEC 61508 and IEC 61511 for functional safety instrumented system and covers the entire life-cycle of safety instrumented systems, from determining risk associated with control systems throughout the project phase. This also includes the separation of basic process control systems and safety instrumented systems (SIS), layers independent protection (LOPs), how to determine safety integrity levels (SILs), technology choices, and field device issues.

This IIPD Global Safety Instrumentation and Emergency Shutdown Systems training primarily focuses on establishing conceptual and detailed design requirements, hazard analysis techniques, safety requirements specification, and the commissioning, operating, and maintenance procedures.

This training will highlight:

• Hazard and Risk Reduction Studies
• Explaining Technology and Equipment Choices
• Safety Requirement Specifications for an SIS
• Selection of Field Devices (Sensors, Programmable Logic Controllers and Valves)
• Establishing Operation and Maintenance Procedures

Course Details

OBJECTIVES

This training is to acquaint instrumentation and control system engineers with the essentials of the IEC 61508 and IEC 61511 safety instrumented systems standards and, how they relate to the safety life cycle of developing and maintaining safety instrumented systems. The fundamental tools will enable delegates to evaluate, design, install, and maintain Safety Instrumented Systems (SISs) and determine their Safety Integrity Level (SILs) requirements.

At the end of this training, you will learn to:

• Understand the requirements of the international standards IEC 61598 and IEC 61511
• Apply the IEC 61508 Safety Instrumented System Development ‘Safety Life Cycle’ model
• Determine the Safety Integrity Level (SIL) using risk assessment methods
• Understand the specifications of emergency shutdown protection requirements
• Establish specification requirements for the sensor, programmable logic controller, and valves
• Follow Management of Change (MOC) procedures for control of future SIS changes
