What may be changing in Annex B of CSA Z662-2023?

CSA Z662 is the Canadian standard for oil and gas pipeline systems, with Annex B specifically focusing on how to perform risk assessments for pipelines. Annex B is currently under review by the Risk Management Task Force and will likely be undergoing significant changes in 2023 to include more guidance on performing risk assessments and quantitative risk criteria for both natural gas and liquid pipelines.

Task Force Chair Maher Nessim, and Task Force work group leaders Mark Stephens of C-FER Technologies and Shahani Kariyawasam of TransCanada, will be leading a work group session at the Banff Pipeline Workshop to discuss the development of the guidance and risk criteria, and how these changes will impact pipeline design and integrity management decisions. If you are interested in learning more about the potential upcoming changes to Annex B, the details of the work group session are as follows:
