Achieved SIL

Process Industries rely upon the performance of Safety Instrumented Functions (SIFs) to protect and maintain operating assets. Engineers and designers are required to calculate the probability of failure of these SIFs to be able to express this performance as a Safety Integrity Level (SIL).


ABB Consulting has created this two day course for engineers or designers who require more detailed training in the concepts and principles that underpin the IEC 61511 functional safety standard and its use for calculating the Safety Integrity Level of a proposed or existing safety instrumented function.


What the course wil cover:
The training course is structured around instruction and workshops that initially explain the underlying concepts of SIL calculation demonstrated on simple Safety Instrumented Functions, then progress through more complicated designs and techniques that are required for higher Safety Integrity Levels.

Following the course you will be able to:
− Understand the concepts underpinning SIL calculation
− Identify what information is essential before starting the SIL calculation
− Apply correct formulae for serial or parallel instrument configurations
− Derive instrument failure rates from commonly available sources
− The benefits and disadvantages of manufacturers certificates
− Appreciate the complexities of a ‘human in the loop’
− What checking and approval is needed for different Safety Integrity Levels
− Calculate the SIL
