Narrative
On 11/29/2018 at 18:53 while lo01 was running in steady state elk city unit 2 shut down on suction pressure low low. The line was immediately shutdown and blocked in. The field, lead and supervisor were notified. Field dispatched to investigate. Release was confirmed by field personnel at app. 10:15. Notifications were made and emergency response activities initiated. Release was due to failure of the long seam. Pipe segment was cut out and replaced on 12-1-2018. Line was recommissioned and returned to service on 12-2-2018. Removed section of piping was sent to lab for metallurgical analysis. G5, item #4 "additional factors" is undetermined for now until the metallurgical analysis is complete. The report will be supplemented upon establishment of failure mode. 2019-02-04 - updated part g, section 5, questions 1, 2, 4 and 5a bases on receipt of draft metallurgical analysis results on 1-25-2019. Updated part e, question 9. Preliminary metallurgical analysis indicates the failure was due to operational pressure cycle fatigue growth that originated from an internal hook crack manufacturing defect. 2019-4-1 - updated part e, items 1 and 2 with more accurate pressure at the point and time of failure and mop at the point and time of failure, per PHMSA request.
