Cause of Problem: Corrosion

On October 12, 2012 at approximately 13:04 hours, a leak was discovered on a six inch fuel gas line located in a pipe rack near the CUS blend drum. The leak resulted in a release of Isobutane and Propane from the process gas piping. The leak was caused by internal corrosion.

Notes/Remedial Actions

Immediately upon discovery of the leak, Motiva operation responded by isolating the six inch fuel gas piping at both ends. Additionally, this section of piping was despressured and taken out of service to stop the leak. The line was then prepared for maintenance inspection. The leak was caused by internal corrosion, and x-ray results revealed pitting at the leak point. On October 16, 2012 Motiva installed an engineered box over the leak point to permanently repair the piping. No mention of any pounds or gallons.
