Narrative
Dcp midstream continued mitigative measures on the rb-1 pipeline due to the release on the pecos river. The cause of that failure was determined by the third party engineering firm, stress engineering, to be induced stray current corrosion (ac and dc). As a result dcp's efforts were focused on evaluating and mitigating stray currents on the entire pipeline. Dcp midstream therefore ran an ili tool on the entire lateral and received all anomalies greater than 59% from the vendor. On 10/6/2016, during efforts to repair an anomaly located about 1 mile west of the pecos river, a pin hole leak was discovered. The pipeline was therefore taken out of service after the pin hole leak discovery and dcp midstream immediately initiated actions to repair the leak. Dcp midstream installed stopples on the pinhole leak and the damaged pipe was cut out and replaced with new pipeline. All repairs were completed and the pipeline was returned to full service on 10/12/2016.
