Purpose
The CSA Z662:19 Standard Oil and gas pipeline systems is currently being reviewed by a CSA task force comprised of industry stakeholders, with proposed changes for Risk Assessment guidance targeted for incorporation in the 2023 Standard. Annex B of the Standard (Guidelines for risk assessment of pipeline systems) has a variety of proposed changes that are in progress. These include but are not limited to the following: 

  • Provide clarity on the distinguishing factors between quantitative vs. qualitative and objective vs. subjective risk estimation methods and measures;
  • Provide guidance on specific quantitative Safety Risk acceptance criteria for both Individual Risk and Societal Risk;
  • Provide guidance on specific quantitative Environmental Risk acceptance criteria;
  • Incorporate as Low as Reasonably Practicable (ALARP) concepts into risk assessments; and,
  • Provide guidance on how individuals might establish their own risk acceptance criteria or apply risk acceptance criteria to more qualitative approaches.

A high level overview of the proposed changes will be presented, then a couple of operators will who have tested out the proposed criteria will be sharing their experience and learnings. An integral part of any risk management is data and data quality. While different operators might have risk models of various advancement levels, one of the common industry challenges is data management and governance. The second part of this session will focus on the challenges associated with data quality evaluation; this can include process maturity, defining data quality and its impact on risk results, identification and prioritization of gaps and ultimately development of risk optimized action plans addressing these data challenges.

Who Should Attend?
This session should be attended by professionals and contractors that conduct/provide risk assessment and management services.
