Narrative
Line 3 was idled in water with corrosion inhibitor. The line has not been used for multiple years. It took a month after initial release for chevron, paramount pipelines and crimson to identify 3 lines in the area as the drawings showed conflicting ownership as well as all three lines being electrically bonded, mostly like to prevent cathodic protection interference. This made identifying the lines difficult. Once paramount pipeline took over ownership of the dig site, the release site was discovered and a temporary clamp placed on the pinhole leak. The was no external corrosion at the release site, which indicated an internal corrosion anomaly. The line was inspected by applus+ rtd. They performed ultrasonic thickness testing at 12 inch intervals in a 6 inch band. All indications point to localized internal corrosion due to a mix of water, crude and corrosion inhibitor which would result in microbiologically influence corrosion as no biocide was put in the line. The line will be repaired with a full encirclement b-sleeve, hydrotested to 675 psi and then maintenance pigged to remove all water. Lastly the line will be placed in nitrogen.
