Narrative
Shell/motiva called phillips 66 bartlesville control center and notified them of a leak on phillips 66 piping inside their texaco valve facility. The leak was venting propane to atmosphere. Phillips 66 pipeliner responded confirming the leak on phillips 66 filter unit. Shell/motiva fire department responded and sprayed water on the leak location until the lel levels dropped for safe ingress/egress to achieve isolation. The source was determined to be a failed nipple due to high cycle fatigue. The release volume was 1.01 bbls of propane. Initial thoughts were that the leak was due to a failed gasket and under the $50k. Once the area was safe and secured we were able to determine actual cause of the failed nipple. Determination at that time was that it could exceed the $50k threshold and an nrc call was made. The actual investigation isn't completed, once it is a supplemental/final report will be issued. -------------------------------------------------------------------------------------------------------------------------------- 07/10/2019 update: lab analysis results the pipe nipple cracked due to high-cycle fatigue initiating at the last engaged thread, most likely due to vibration in the equipment nearby. The metallurgical analysis revealed: the straight, non-crystallographic, and non-branching cracks confirmed failure due to fatigue. Beach marks and fine striations on the pipe fracture surface confirmed high cycle fatigue. The crack morphology ruled out stress-corrosion cracking and internal corrosion.
