Keystone Pipeline Oil Spill Repair and Investigation

under repair and investigation

The Keystone Pipeline experienced a rupture caused by a fatigue crack along the pipe's manufactured long-seam weld, resulting in an oil spill in North Dakota. The spill released approximately 3,500 barrels of oil onto farmland. The pipeline was shut down, the failed section was excavated and replaced, and cleanup operations were conducted. The pipeline was restarted after a six-day shutdown with reduced operating pressures and continuous monitoring. Investigations and remedial evaluations are ongoing to ensure pipeline integrity.
