Location
TX
Narrative
Shell pipeline was notified by a third party of oil on the right of way. The source of the oil was determined to be a crack in a girth weld. While the evidence on site did not allow the cause to be definitively determined, it is speculated that mechanical stress on the weld contributed to the failure and that there may have been a pre-existing weld defect that originated during construction of the pipeline. The pipeline was repaired by installation of a type b steel sleeve. 5/13/2013 supplemented with pipe data as requested by PHMSA.
