Narrative
On april 20, 2015 an explorer pipeline employee identified product seeping from a one-inch threaded pipe connection off the unit number 1 pump seal flush line at the springfield, mo pump station. The employee notified the explorer pipeline control center, who shut down the pipeline and isolated the pump station from the mainline. The source of the release was confirmed to be a crack in the threaded connection of a one-inch piping associated with the pump seal flush. A failure analysis was conducted on the one-inch threaded pipe connection by a third party and explorers engineering department. It was determined long term cycling of the one-inch piping from vibration at the springfield, mo pump station was the direct cause. Three-quarter inch stainless steel tubing and swagelok connections along with pump mounted bracing are being installed to replace the piping to reduce the residual vibration. Any impacted soil from the release was testing, and approximately 14 cubic yards of soil was removed.
