Standards and Recommended Practices require periodic updating so they represent current technology and industry practices. Canadian Standards Association (CSA) Z662 “Oil and Gas Pipeline Systems” contains Annex E that covers software-based leak detection for liquid hydrocarbon pipelines. The CSA Technical Committee determined that is was time to update Annex E. A Task Force of industry experts and regulators met over a period of 18 month to draft a new Annex E. This paper outlines some of the significant features of the new Annex and where possible does a comparison with the similar section in American Petroleum Institute’s API 1130 which covers recommended practice for software based leak detection in the US. A pipeline operator should consider using both Annex E and API 1130 in the implementation and use of a software-based leak detection system. The CSA Task Force did not want to copy and modify API 1130 to provide a new Annex E, so both documents provide necessary information.

Provide Background Information

State-of-the-art Engineering Critical Assessment (ECA) employs the methodology of the Failure Assessment Diagram (FAD) for stress-based design. Current versions of FADs used in leading standards are reviewed and applied to girth weld flaws in pipelines. The intent of the work is to provide background information as a contribution to a proposed upgrade of the Canadian Standards Association standard Z662, “Oil and gas pipeline systems”.

The need to develop an accurate, autonomous, and economical pipeline mapping system capable of use within a wide range of pipeline sizes, configurations, operating pressures and specific uses was accomplished, resulting in the manufacture of a series of unique inertial-based smart probes. This paper reviews the innovative technology developed to identify, map and plan for the management and integrity of pipeline assets through use of the smart probe technology. Today’s owners and operators of the world’s pipeline infrastructure are faced with competitive pressures and regulatory constraints which are creating increasingly stringent demands to manage our pipeline assets in an efficient and responsible manner. Billions of dollars will be spent over the next 20 years to rehabilitate the world’s infrastructure and oil and gas pipeline systems. “Out of sight – out of mind” no longer applies. Now, more than ever, pipeline owners and operators need solid information to plan for the challenges of tomorrow.
