Narrative
Pipeline operator excavated pipeline to examine dents indicated by an in-line inspection (caliper) tool in an area where there had been no indications of damage in the past from previous in-line inspection runs. A small leak was found before reaching the top of the pipe. The line was shut down and then stoppled upstream of the area of damage and was shut down downstream with an existing line valve. The line was fully excavated exposing latent third party damage from a contractor using a backhoe/trackhoe. The line had been dented and gouged in two places with one of the gouges splitting open causing a small leak on the line. The damaged area of the line was cut out and a new spool piece was welded in place.
