Functional Safety Training

Picture1trd (2).png


In this training, Safety Instrumented System (SIS) engineering, Life Cycle and Validation and Verification calculations will be explained within the framework of IEC EN 61508 and IEC EN 61511 standards.

1) Why Do We Need Functional Safety?

        Reliability and Probability Theorems

        Key Features of Critical Systems

        V-Model Cycle (VDI 2206, 2004)

        Functional safety standards (IEC 61508, IEC 61511, IEC61511 ISA SP 84.01)

2) IEC 61882- "Hazard and operability studies (HAZOP studies) - Practice guide"

        Layer of Protection Analysis (LOPA)

3) SIS Design

        IEC 61508 - Risk Chart

        IEC 61508 and IEC 61511 - Security: How Do We Achieve High Reliability?

        IEC 61508 and IEC 61511 - Safety Lifecycle

        What is SIS, SIF, SIL?

4) What is Voting?

        What is Voting?

        Demand Mode (Demand Mode)

        Risk Reduction Factor (RRF)

        TI: Test Interval (proof)

5) SIS Validation and Verification Calculations

        Probability of Failure on Demand (PFD)

        Common Failure Mode (Beta Factor)

        Fault Types

        Hardware Fault Tolerance - (Hardware Fault Tolerance - HFT)

        Dangerous Fault Tolerance (DFT)

        Safe Fault Tolerance - (Safe Fault Tolerance- SFT)

        Failure Rate, Including Diagnosis and Diagnosis

        Safe Failure Fraction – SFF (Safe Failure Fraction)

        SIS verification

        Mean Time To Fail Spurious - MTTFS

        Spurious Trip Rate (STR)

6) Engineering and Design Applications

        Requirements of Protective Functions

        Device Selection - Comparison of Electronic and Mechanical Parts

        Device Selection-Proven-in-use by NAMUR (NE130)

        Fault Detection During Maintenance and Test-Operation

        Maintenance and Test-Maintenance Intervals

        Last Element

        Actuator Strength and Torque - Globe and Ball Valve

        Actuator Strength and Torque-Butterfly Valves

        Installation - Assembly and Piping

        Maintenance and Testing - Evidence Test/Service Life
