Pipeline operator had a called internal anomaly, that had to be investigated. The pipeline was in a inland drinking water reservoir with 7 feet of mud cover and 19 feet of water with 5 ½” concrete coating. We had the task of connecting portable barges together, load crane, deep water caisson along with many other pieces of equipment needed to expose pipe. Once pipe was exposed concrete was removed, pipe was then sand blasted. NDE then performed evaluation of defect, once evaluation was complete repair method was to install type B sleeve, pipe was then coated and site was then backfilled to previous cover.
