Narrative
At 8:00 pm on december 13, 2011,center point energy called the control center notifying them of a gas odor at hwy 3 and brookglen drive in houston, tx.The control center called the operations on call person to respond. Local operations personnel discovered an lel around a 10 foot area of the intersection of highway 3 and brookglen drive. Emergency response procedures were initiated and at the request of the tpc plant, a controlled shutdown was coordinated which allowed them to get another supplier online before the pipeline was shut down and isolated. A portable flare was brought out to flare down the pipeline. The pipeline was purged and inerted with nitrogen by approximately 10:00 pm on december 14, 2011. Excavation of the release site was started on december 15, 2011 and the damaged section of pipe was identified in the afternoon located approximately 20 feet inside the casing under brookglen drive. It was decided to repair the pipeline by excavating both ends of the casing and replacing the entire pipe section inside it. The installation of the certified replacement pipe was completed on december 18, 2011 and the pipeline was returned to service on december 20, 2011. No further remediation or repairs are necessary. Analysis of the damaged area of the pipe determined the cause to be external corrosion due to being shorted to the casing. During excavation it was discovered that the vent pipe was detached from the casing resulting in a bad cp reading. New casing vents were installed on both sides of the casing. Supplemental report filed to correct part c, question 1. April 17, 2015 update included pipe manufacturer.
