Narrative
The dfw pipeline was being swept with nitrogen as part of a final abandonment. The pipeline had been reported as purged by the previous operator and had not been operated in 20+ years, but some liquids were encountered. While pushing the pig with nitrogen, it was observed that pressure no longer could be increased once the pigs has passed valve 4. The purge was shutdown, line blocked in and field personnel dispatched to walk the line. The leak was located about 3/4 miles east of block valve no. 4. Upon excavation it was identified that the line had suffered a previous external strike. That damage had been repaired with a skinner type pipe clamp, which was the source of the failure. The clamp utilized is not considered to be an approved repair clamp and was replaced in order to complete the purge. The purge of the line has subsequently been completed and the line abandoned.
