RP2.3-05 ALARP decision making

Executive Summary

The pipeline sector puts significant effort in to managing the potential for high consequence, low frequency accidents. For transmission pipelines, the framework for these activities is set out in AS/NZS 2885 Part 6 Pipeline Safety Management. The requirements guide important decisions and significant expenditure.

New requirements were developed in 2014 to 2018 and included in the current version of the standard issued in 2018, in particular requirements about recognition of high consequence events and formal demonstration that risk is as low as reasonably practicable (ALARP). The scope of this research is to investigate the experience of industry in implementing these requirements with a view to determining how safety decision making could be further improved, particularly in the context of future fuels. Outputs informed by the research could be considered in the next revision of the standard or may take the form of additional guidance / tools outside the formal Standards Australia documentation.
