Narrative
During the aerial patrol of the oneok creek pipeline on 9/26/2018 the pilot observed what appeared to be ice over the pipeline on the downstream side of slick rd. Local oneok field operator was contacted by the pilot and dispatched to the location. Field operator identified ice, dead vegetation and vapors coming on the right-of-way directly above the pipeline. Pipeline control and operations supervisor were contacted and the pipeline was shut down and the location was isolated. Repair crews excavated the pipeline and discovered a pinhole leak. A plidco mechanical repair clamp was installed and the pipeline returned to service. Oneok's investigation determined the interference causing the leak resulted from a negative cable being installed to the casing, instead of the mainline, by a contractor in september of 2017. The cable was associated with a new ground bed that had been installed in june of 2017 with the rectifier at the location being energized in november of 2017. 12/21/2018 correction - corrected part b, question 10 to show accident occurred on pipeline right of way.
