Enbridge Pipelines Inc. has reported to the National Energy Board about cracks identified in its new Southern Lights LSr pipeline between Cromer, Manitoba and Gretna, Manitoba.
During construction of the NPS 20 Line 65 Cromer (CM) to Gretna (GF) section of the LSr Project, two hydrotest releases occurred. The first release occurred at construction KP 17+303 when a long seam defect failed. The second release was a pinhole leak that occurred at construction KP 54+348, also caused by a long seam defect. These two joints of pipe were removed. Enbridge's study attributes the cracks to isolated events of power drop during welding.
