Narrative
While performing a dig to repair an anomaly discovered on an in-line inspection assessment, a nustar maintenance employee noticed a hydrocarbon odor coming from the soil. Upon investigation, a pinhole leak was discovered. A type-b sleeve was installed to repair the leak. The failed segment of pipe will be removed and examined to determine the cause of the failure. Update- the leak occurred in a portion of the longitudinal seam which was malformed. Misalignment of the seam during the manufacturing process contributed to the malformation.
