Safety Instrumented Systems (SIS): Design, Implementation, and Lifecycle Management

Modern process industries—oil & gas, chemical, petrochemical, power, pharmaceuticals, and manufacturing—operate in increasingly complex and high-risk environments. Safety Instrumented Systems (SIS) play a critical role in preventing catastrophic incidents by automatically taking systems to a safe state when hazardous conditions arise.

This comprehensive online course on Safety Instrumented Systems (SIS) is designed to provide engineers, safety professionals, and technical managers with a practical, standards-based understanding of SIS design, implementation, operation, and lifecycle management in accordance with IEC 61511 and IEC 61508.

The course bridges the gap between theory and real-world application, guiding learners through the complete SIS lifecycle—from hazard identification and risk assessment to Safety Integrity Level (SIL) determination, system design, verification, validation, operation, maintenance, and auditing.

What You Will Learn

By the end of this course, participants will be able to:

• Understand the fundamental principles of functional safety and the role of SIS in process risk reduction
• Interpret and apply IEC 61511 and IEC 61508 requirements correctly
• Identify hazards using HAZID, HAZOP, and LOPA methodologies
• Determine Safety Integrity Levels (SIL) based on risk analysis

• Define and document Safety Instrumented Functions (SIFs)

• Design SIS architectures, including sensors, logic solvers, and final elements
• Perform SIL verification calculations (PFDavg concepts and architectural constraints)
• Understand proof testing, diagnostics, and common cause failures
• Manage SIS operation, maintenance, and modification (Management of Change – MOC)
• Conduct SIS audits, assessments, and performance monitoring
• Avoid common SIS design and implementation pitfalls seen in real plants
