Course Overview

The Safety Instrumented Systems (SIS) Training Course provides a comprehensive and practical framework for understanding, designing, operating, maintaining, testing, and managing safety instrumented systems in industrial and process environments. The course focuses on the role of safety instrumented systems in reducing operational risk by detecting hazardous conditions and initiating predefined protective actions when normal process control systems are unable to maintain the process within safe operating limits. The program examines the architecture, functionality, lifecycle, and management requirements of safety instrumented systems and their relationship with process control systems, field instrumentation, shutdown systems, alarms, and other independent protection layers. Participants will develop a clear understanding of how safety instrumented functions are identified, specified, designed, implemented, verified, validated, operated, tested, and maintained throughout the system lifecycle. A strong technical emphasis is placed on safety instrumented functions, safety requirements, safety integrity, sensors, logic solvers, final elements, redundancy, diagnostics, proof testing, bypass management, failure analysis, and system availability. The course also explores how engineering decisions and maintenance practices influence the ability of an SIS to perform its intended protective function when required. Through practical industrial scenarios, technical exercises, and structured workshops, participants will develop the ability to assess SIS architectures, review safety requirements, analyze potential failures, evaluate testing and maintenance strategies, and identify opportunities to improve system reliability and functional safety performance. The course is particularly relevant to high-hazard environments where reliable protective systems are essential to controlling process risks and supporting safe operations.

Learning Objectives

  • Analyze the purpose, architecture, and operating principles of Safety Instrumented Systems during the course.
  • Evaluate the relationship between Safety Instrumented Systems, process control systems, alarms, and independent protection layers.
  • Identify Safety Instrumented Functions and translate process hazards into appropriate safety requirements.
  • Assess the functional requirements of sensors, logic solvers, and final control elements within an SIS.
  • Apply principles for developing and reviewing Safety Requirements Specifications.
  • Evaluate safety integrity requirements and their influence on SIS architecture and design.
  • Analyze failure modes, diagnostic capabilities, redundancy, and common cause considerations affecting SIS performance.
  • Develop effective approaches for proof testing, inspection, maintenance, bypass management, and system lifecycle control.
  • Evaluate SIS performance, reliability, testing results, and maintenance practices to identify potential weaknesses.
  • Develop an actionable improvement plan for the management, operation, maintenance, and lifecycle assurance of safety instrumented systems.

Who Should Attend

The Safety Instrumented Systems (SIS) Training Course is designed for engineers and professionals working in functional safety, process safety, instrumentation and control, automation, electrical engineering, operations, maintenance, reliability, and industrial risk management. It is particularly relevant to instrumentation engineers, control engineers, automation engineers, process safety engineers, functional safety engineers, electrical engineers, reliability engineers, maintenance engineers, process engineers, and technical specialists responsible for safety-related systems. The course is also suitable for engineering managers, process safety managers, operations managers, maintenance managers, reliability managers, project managers, asset managers, technical authorities, HSE professionals, auditors, and senior decision makers involved in the design, approval, operation, maintenance, testing, or assurance of safety instrumented systems. It is highly relevant to government entities, ministries, oil and gas organizations, refineries, petrochemical facilities, chemical plants, energy companies, utilities, manufacturing facilities, and other high-hazard industrial operations.
