Narrative
While conducting an over flight, the marathon pipe line (mpl) technician and mpl contracted line flyer noticed a visible sheen at coordinates consistent with ssva #2 in sp88. A shaft seal failure on a 6" check valve for the lateral to sp 87d was releasing crude oil. The valve was evaluated by cameron valves and measurement on july 20, 2010. Valve was determined to have been in operation either without the environmental cover or with the environmental cover not tightened down completely. This resulted in the wearing of the extended shaft and galling in the radial seal area due to the intrusion of debris into the area between the shaft and the gland.
