Course description
Design SIL Achievement (T243)
A practical training 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 verifying the achieved Safety Integrity Level (SIL) of the proposed or existing Safety Instrumented Function (SIF).
Process Industries rely upon the performance of Safety Instrumented Functions (SIFs) to protect and maintain operating assets. Engineers and designers are required to verify if the designed process is safe and the SIFs meet the requirements for their SIL.
ABB has created this two day course for engineers and designers who require more detailed training in the concepts and principles that underpin the IEC 61511 functional safety standard and its use for verifying the Safety Integrity Level of a proposed or existing safety instrumented function.
The course is structured around instruction and workshops that initially explain the underlying concepts of safety device selection and verification for meeting the Target SIL requirements identified in the Safety Requirements Specification (SRS).
Upcoming start dates
Suitability - Who should attend?
The course is aimed at engineers and designers involved in SIF device selection and for verifying the performance of new or existing safety instrumented functions. The course features a number of workshops to enable delegates to practice using the formulae on ever increasing complex examples.
Outcome / Qualification etc.
Following the course you will be able to:
- Understand the concepts underpinning SIL achievement requirements
- Identify what information is essential before starting the calculation
- Apply correct formula PDFavg / PFH for serial or parallel instrument configurations
- Derive instrument failure rates from commonly available sources
- The benefits and disadvantages of manufacturers certificates
- What checking and approval is needed for different Safety Integrity Levels
- Verify the achieved SIL from a number of worked examples
Training Course Content
This Design SIL Achievement training course follows the following training agenda:
