Safety Instrumented Systems (SIS) for Process Industries Using IEC 61511 and IEC 61508 Course

Course Overview:

This course provides a thorough understanding of Safety Instrumented Systems (SIS) and their application to industrial processes with special emphasis on international standards such as IEC 61508 and ISA S84. Students enrolled in this course will obtain knowledge about basic safety instrumentation, hazard studies, risk mitigation and the creation of Safety Requirement Specification (SRS).

The course also includes SIS design, hardware and software engineering, SIS installation, commissioning, and maintenance practices. 

The course is appropriate for engineers, technicians and managers working in the process industries and provides the then knowledge and ability to design, implement and maintain high-reliability safety systems that provide functional safety and operational excellence.

Theoretical and practical aspects of functional safety systems are combined through interactive discussions, empirical case studies approaches, and best practice information.

Course Objectives:

Aim & Objectives competencies: Attendant trainees will be able to…

• Expand your practical knowledge in the application of safety instrumented systems (SIS) as applied to industrial processes
• Provide you with the knowledge of the latest standards dealing with each stage of the safety life cycle from the Initial evaluation of hazards to the detailed engineering and maintenance of safety instrumented systems
• Give you the ability to plan hazard and risk assessment studies, then design, implement and maintain the safety systems to ensure high reliability

Course Outlines:

Introduction

A review of the fundamentals in safety instrumentation focusing on a discussion on hazards and risks, safety systems engineering, and introduction to the IEC 61508 and ISA S84 standards.

A concluding review of the safety life cycle model and its phases.

Hazards and risk reduction

An examination of basic hazards, the chemical process, hazards studies, the IEC model, protection layers, risk reduction, and classification and the important concept of the safety integrity level (SIL).

Hazard studies

A review of the outline of methodologies for hazard studies.

Safety requirements specifications

A discussion and guide to preparing a safety requirement specification (SRS).

Technology choices and the conceptual design stage

An examination of how to get the concepts right for the specific application and choosing the right type of equipment for the job, not the particular vendor but at least the right architecture for the logic solver system and the right arrangement of sensors and actuators to give the quality of system required by the SRS.

Basic reliability analysis applied to safety systems

This discusses the task of measuring or evaluating the SIS design for its overall safety integrity.

Safety in field instruments and devices

This module examines the range of instrumentation design techniques that have accumulated in the industry through experience that began a long time before the days of PES and the high-performance logic solvers.

Engineering the safety system: HARDWARE

An examination of two aspects of engineering work for building an SIS. Firstly there is a look at some aspects of project engineering management and secondly some basic engineering practices.

Engineering the safety system: SOFTWARE

Guidance is provided here on how to deal with the application software stages of an SIS project with an examination of some of the basic concepts and requirements that have been introduced in recent years to try to overcome the major concerns that have arisen over the use of software in safety applications.

Overall planning:

IEC Phases 6, 7 and 8

A brief look at the planning boxes marked in on the IEC safety life cycle.

Installation and commissioning (IEC phase 12)

This module tracks the safety system from its building stage through factory acceptance testing, delivery and installation and into final testing for handover to the operating team.

Validation, operations, and management of change

(IEC phases 13, 14 and 15)

A discussion on validation, operations, and maintenance.

Justification for a safety instrumented system

In practice engineers and managers have to make choices on the type, quality, and costs of the safety solutions available within the constraints imposed by the essential safety requirements. This is discussed in detail in this module
