Artificial Intelligence – The rise of the machines
Assuring the safe operation of artificial intelligence systems.
An introduction to functional safety assurance
If you’ve ever wondered what’s meant by the term functional safety assurance, you’re not alone. Simply put, functional safety assurance is the process by which we ensure that safety-related systems do what we need them to do, when we need them to do it, so that risk is maintained at tolerable levels. But what does this mean in practice?
Cyber-security meets functional safety
The cyber-threat to industrial control systems is very real, as demonstrated by high profile attacks in recent years.
Introduction to PSA
Probabilistic Safety Assessment (PSA) provides an integrated and structured safety analysis for a nuclear facility that combines consideration of engineering design and operational features in a consistent framework. This established and systematic technique identifies all significant fault sequences which can lead to a radiological release and assesses their contribution to risk, on a best-estimate basis.
Introduction to QRA
Risk is defined as the combination of the probability of an event and the consequences of the event, but how do you go about undertaking a full Quantitative Risk Assessment (QRA) for an offshore oil and gas facility or an onshore petrochemical plant?
An introduction to safety-critical software
Software is often used to implement the functionality of safety systems because it can be designed to handle complex functionality, is accurate and repeatable, and can be cheaper than hardware solutions. However, there are many examples of safety systems which have failed due to software related faults.
