F.S. ENG. New Update of SIS-IEC 61511 ED. 2


F.S. ENG. New Update of SIS-IEC 61511 ED. 2

Professional Development: 

One classroom day providing ACM Facility Safety attendance diploma to use as indication of current up to date knowledge concerning Functional Safety standard for Safety Instrumented Systems, IEC 61511:2016, Ed. 2

Course Benefits: 

This training course will provide participants with the ability to understand the implications and changes to the IEC 61511 international standard. Offers F.S. Engineers, maintenance personnel, operations, and supervisors the important information in the new standard IEC 61511:2016, Ed. 2; thereby increasing their expertise. It will also provide engineers dealing with Management of Change the ability to speak the same language as the operators of the facilities.

Course Overview: 

The informative one day session is designed to summarize and highlight the changes within Edition 2 of IEC 61511:2016. The session offers F.S. Engineers, or industry practitioners, who additionally possess significant work experience in the field of functional safety, the ability to keep updated with the new standard IEC 61511:2016, Ed. 2 increasing their expertise.

Modifications to IEC 61511, 2nd edition, include:

  • Digital (cyber) security
  • Regular functional safety audits (FSA)
  • Competency requirements
  • Requirements for safety requirement specifications (SRS)
  • Process safety time (PST)
  • Specific requirements added for managing a SIF
  • More emphasis that failure rates used during the reliability calculations
  • Systematic and random failures
  • Safety Manuals
Who Should Attend: 

This session is well suited to engineers and technologists who aim to follow the best engineering practices with regard to the application of Safety Instrumented Systems in the process industry, including:

  • Risk professionals responsible for establishing corporate tolerable risk targets
  • Managers / Team Leaders responsible for determining SIS design standards
  • Engineers and technicians responsible for ensuring that SIS have been designed to appropriately mitigate the level of risk identified
  • Project Managers who need to understand the concepts and principles of IEC 61508 & 61511
  • Engineers involved in any aspect of the SIS Safety Lifecycle
  • Original Equipment Manufacturers, OEMs, such as manufacturers for Boilers, Compressors, Furnaces, Burner systems, Flare systems, etc.
Course Outline: 

The session main scope is as follows:
