GE Oil & Gas Inspects Section of TransCanada’s Keystone Pipeline

Posted on April 6, 2009

GE Oil & Gas' PII Pipeline Solutions group is completing its largest pipeline inspection project by helping TransCanada evaluate the condition of an 864-kilometer (537 mile) portion of a natural gas pipeline in Canada. This part of the pipeline, which covers a span equivalent to the distance between Paris and Berlin, needed to be inspected prior to being converted to carry crude oil as part of the Keystone Oil Pipeline.

TransCanada is converting its 34-inch, Mainline gas pipeline between Burstall, Saskatchewan and Carman, Manitoba as part of TransCanada and ConocoPhillips’ joint Keystone Oil Pipeline project. The initiative will allow crude oil to be transported to U.S. Midwest markets at Wood River and Patoka, Illinois and to Cushing, Oklahoma.

To ensure optimal availability of the converted pipeline, TransCanada first had to make sure it was free of stress corrosion cracking (SCC) that could potentially lead to leaks. Between October 2008 and March 2009, GE’s field team performed crack-detection inspection runs in three segments of the natural gas pipeline of 294, 315 and 255 kilometers in length, respectively.

"GE was selected by TransCanada because we were the only company with both the experience in using ultrasonic tools for crack detection and the resources to manage this critical project’s scope and technical requirements, particularly the need to deploy multiple tools over such a vast distance,” said John Bucci, general manager for GE Oil & Gas’ PII Pipeline Solutions business.
