Narrative
During a weather-related power outage, a nustar employee discovered a crude oil leak at nustar's wichita falls pump station while preparing the station for restart. A 3/4-inch steel cooling tubing separated from the station's unit no. 2 outboard bearing. A pressure spike within the unit no. 2 suction piping, caused by the failure of a pump station check valve, contributed to the failure of the tubing fitting. The tubing fitting has been removed and sent to a laboratory for analysis. The tubing fitting and check valve have been replaced. Update - the failure was due to incomplete installation of the tubing in the fitting. Fitting ferrules were inadequately seated on the tubing.
