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).

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:

SIL as part of functional safety

  • Why do we need functional safety and safety instrumented systems?
  • Functional safety standards; IEC61511 and IEC61508
  • ‘Three Steps’ to SIL; SIL Determination, Achieved SIL, Operations and Maintenance

Setting the target SIL

  • Risk and risk reduction
  • Reminder of hazard identification and SIL determination

Safety requirement specification

  • Information to be specified to design group or external company

Designing for SIL

  • The calculated failure measure (PFDavg / PFH)
  • SIF architectural constraints on hardware safety integrity (Route 1H, 2H and IEC61511 requirements)S
  • IF systematic safety integrity requirements (Route 1s, 2s and 3s) prior use and proven in use concept
  • Requirements for system behaviour on detection of a fault
  • SIF bypassing
  • SIS operator / maintenance interface and communication interface requirements

SIL Verification Calculations

  • Reliability and availability
  • PFDavg calculations 
  • IEC 61511 requirements for reliability data quality
  • Common cause effect on the calculated measure
  • SIF subsystem redundant architectures - comparison and calculation formulas
  • Proof test concept
  • The effect of proof test effectiveness
  • Partial testing

SIL device selection

  • Basic design requirements from safety standards
  • Required information from a device manufacturer for safety-related device
  • IEC 61508 certification process
  • Other options of compliance - prior use and proven in use
  • What can be found in the certificate
  • Certification limitation
  • FMEDA reports
  • Quality and Functional safety management systems for the suppliers
  • A device safety manual


This Design SIL Achievement training course is priced at £1,220 +VAT per delegate.
