Name
WG 2 Session C - A Risk-Consistent Safety Class System
Date & Time
Monday, April 12, 2021, 1:00 PM - 2:30 PM
Maher Nessim Kim Maddin Scott Ironside
Description

Building on the tutorial on Safety Class Systems, this session will provide a panel discussion on a whole new approach to class location changes for potential future editions of CSA Z662. Six pipeline safety classes have been defined and an approach to assign a safety class to any individual pipeline has been developed. To ensure risk consistency, the safety class assignment is based on the line attributes that control failure consequences, including diameter, pressure and population density for gas pipelines, and diameter and site sensitivity for LVP liquid pipelines.

  • Overview of Safety Class Systems
    • Brief highlight on the principles of safety classes and how this system aligns with hoop stress safety factors and other methodologies such as currently described in CSA Z662 Annex C and Annex O (Maher Nessim - CFER)
    • Q&A/Panel Discussion
  • Industry perspective on Safety Class Systems
    • Discussion on impact to industry (Kim Maddin - TC Energy, Scott Ironside - Enbridge)
    • Q&A/Panel Discussion
  • Full panel discussion
