Narrative
Approximately 15 bbls of crude oil were released from the mechanical seal on tank mixer 202656 c. The mixer was isolated as well as locked and tagged out. The manufacturer is performing failure analysis in addition to plains conducting seal failure analysis in order to verify the root cause. A supplemental report will be submitted once the results are received. Supplemental narrative: mixer 202656c had high vibration caused by a large clearance between inboard bearing sleeve and shaft. A new sleeve (or bearing assembly) was installed and a new mechanical seal, under warranty. Stronger set screws were also installed on the inboard sleeve to shaft connection. Vibration was deemed acceptable after repair.
