About the session
This talk describes the approach we took to resolve a log jam in a cogen power plant development project in Australia. The importance of the following aspects is emphasized, and practical solutions discussed:
* A clear, agreed and detailed Functional Safety Management Plan
* Documented, auditable justification of the decisions made in the SIL determination activity
* Resolution of disputes based on data and evidence, not gut feelings or personal experience alone
* Demonstrable, documented verification of each lifecycle phase.
Industry increasingly relies upon safety systems to maintain and protect operating assets.
Systems comprised of electrical or electronic elements have been widely used to perform safety functions in most application sectors.
The oil and gas industry, nuclear plants, and transport sector, to name but a few, all rely heavily on functional safety.
The functional safety compliance requirements of IEC 61508 and IEC 61511 and other standards covering safety-related systems are increasingly being specified in procurement specifications in a wide range of sectors and increasingly diverse applications.
The standards are also being used not just for functional safety but also for asset protection.
Allied to the need to have adequate levels of functional safety to meet safety / environment risks is the need to ensure that safety-related systems are properly protected against cyber-attacks. The latter is becoming increasingly important, hence a Workshop on Cyber Security for Safety Critical Systems this year.
