Incident Narrative

ON JANUARY 13, 2020 AT 7:35AM, STAKEHOLDER CRUDE OIL MANAGER, ARRIVED AT THE SAN ANDRES CG TERMINAL LOCATED AT 2554 CR 195, DENVER CITY, TEXAS. SHORTLY AFTER CRUDE OIL MANAGER ARRIVED, HE DISCOVERED TRANSFER PUMP NUMBER 1 WAS LEAKING CRUDE. PUMP WAS ALREADY SHUT DOWN AS PART OF NORMAL OPERATIONS, THE PUMPS AUTOMATICALLY SHUT DOWN ONCE THE DAILY DELIVERY ARE MET. CRUDE OIL MANAGER SHUT THE VALVES ISOLATING TRANSFER PUMP NUMBER 1. ONCE THE PUMP WAS ISOLATED CRUDE OIL MANAGER NOTIFIED HIS CORPORATE OFFICE THAT TRANSFER PUMP NUMBER 1 HAD LEAKED WHILE OPERATING. CRUDE OIL MANAGER THEN CALLED STAKEHOLDERS CONSTRUCTION MANAGER, TO ASSIST IN THE REMEDIATION OF THE SITE. A VAC TRUCK WAS DISPATCHED TO THE SITE TO RECOVER STANDING CRUDE OIL. AFTER ALL THE STANDING CRUDE WAS RECOVERED, A BACKHOE CONSOLIDATED THE CONTAMINATED SOIL INTO ONE LOCATION ON THE SITE. E-TECH ENVIRONMENTAL TECHNICIAN WAS ON SITE TO PERFORM AN ASSESSMENT OF THE SITE TO EVALUATED WHAT WAS NEEDED TO COMPLETE THE REMEDIATION. E-TECH WILL COMPLETE THE REMEDIATION ON OR AROUND FEBRUARY 7, 2020. THE PUMP MECHANIC WAS ON SITE AFTER THE SITE WAS MADE SAFE AND ACCESSIBLE TO START A ROOT CAUSE ANALYSIS. THE PUMP MECHANIC FOUND THE MAIN SEAL TO BE LEAKING AND THE CRUDE OIL MANAGER DECIDED TO SEND THE PUMP ROTATING ASSEMBLY TO THE SHOP FOR FURTHER ANALYSIS AS THE MAIN BEARINGS HAD FAILED. AFTER THE ANALYSIS OF THE ROTATING ASSEMBLY IT WAS DETERMINED THAT THE MAIN BEARING HAD A COMPLETE FAILURE. TRANSFER PUMP NUMBER 1 WAS INSTALLED ON 7/18/2019, AT THE TIME OF THE ROTATING ASSEMBLY ANALYSIS IT WAS DISCOVERED THAT THE ROTATING ASSEMBLY WAS NOT AN OEM PART FROM THE PUMP MANUFACTURE AND MISALIGNMENT OF THE AFTERMARKET ROTATING ASSEMBLY MAY HAVE CONTRIBUTED TO THE MAIN SEAL FAILURE. THE EXACT CAUSE OF THE BEARING FAILURE COULD NOT BE DETERMINED DURING THE ROTATING ASSEMBLY ANALYSIS. THE MAIN SEAL FAILED DUE TO THE VIBRATION FROM THE BEARING FAILURE ON THE ROTATING ASSEMBLY. THERE IS A TOTAL OF THREE TRANSFER PUMPS SIMILAR TO TRANSFER PUMP NUMBER 1 IN SERVICE ON STAKEHOLDERS TERMINAL. TO PREVENT FUTURE RE-OCCURRENCE OF THE SAME TYPE OF FAILURE STAKEHOLDER WILL NO LONGER ACCEPT ANY AFTERMARKET PARTS TO BE INSTALLED ON THEIR PUMPS. THE THREE SIMILAR PUMPS WERE INSPECTED TO ENSURE THAT THEY ALL HAD ORIGINAL MANUFACTURE ROTATING ASSEMBLY'S INSTALLED.
