Narrative
On 8/29/2012 a rehab crew was investigating an anomaly on the eldorado-coffeyville blue line at am92. The nde technician was finishing up and noticed bubbling on the pipe on a girth weld. The leak was very small and not detectable utilizing a haz-gas monitor. The contract operations representative immediately shutdown the work and closed the permits and notified the area operations supervisor at 1355, and then notified pipeline control of the pinhole leak. Field investigation and photographic documentation of the site determined the pinhole is not associated with the target anomaly or other close anomalies. Additionally, examination of other anomalies on the pipeline identified no other leaking pinhole anomalies. A plidco clamp was installed as a temporary repair measure. A secondary review of ultrasonic nde data confirmed the cause of the release was a pinhole weld defect. The pipe was cut out on 8/28/2013 and sent for metallurgical analysis. Metallurgical analysis concluded the leak was the result of a pre-existing defect in the girth weld presumably produced during construction of the pipeline. This leak was the result of a welding suck-back that was unrepaired, along with an off-center weld cap. Note: regarding part c 3.G year of manufacture: the date of the pipe manufacture is unknown, however, due to limitations with the PHMSA form not allowing an unknown value, the year of manufacture is estimated based on the year installed.
