Complex systems and equipment are increasingly using electrical, electronic or programmable electronic systems to perform multiple functions, some of which have significant safety implications if they fail to be performed correctly. Functional safety is a formal discipline that analyses a system to identify: 

  • Safety Function Requirements - what safety functions are performed by the system
  • Safety Integrity Requirements - what degree of certainty is necessary that the safety function will be performed without a dangerous failure

A number of international and national functional safety standards exist that define the requirements for identifying, allocating, analysing and verifying safety integrity levels for functions. Regulators rely on these standards to help ensure all parties involved in delivering, operating and maintaining a complex system that performs safety functions, meet their legal duty of care to guard against negligence.

AMOG has been providing expert functional safety services to the Rail Sector across a number of asset and safety critical environments for more than a decade. AMOG's functional safety expertise includes:

  • Expert working knowledge of functional safety standards such as IEC/AS61508, EN50126, EN50128, and EN50129
  • SIL allocation using formal qualitative and quantitative techniques such as risk assessments, HAZOPs, and LOPA
  • Safety Requirements determination
  • Hardware SIL assessments and independent SIL verification using techniques such as Fault Tree Analysis and FMEDA to determine PFH/PFD
  • Systematic Integrity Assessments
  • Software SIL assessment and verification
  • Independent Functional Safety Assessments (FSA)

AMOG's extensive experience in functional safety engineering, highly qualified and dedicated team of professional functional safety engineers (Masters Qualified, TÜV FSE certified), and state-of-the-art software makes AMOG the smart choice for all of your functional safety needs.
