Narrative
An operator conducting his afternoon rounds found crude oil leaking from the mixer on tank 125. The mixer was running when the operator found it and he immediately shut the mixer off and notified the shift supervisor. When the mixer was shut off the leak stopped. A containment device was placed below the mixer and the mixer has remained off since nov 10 cmr personal determined that the cause of leak on the mixer was due to a mechanical seal failure. The tank product level, in the tank, has been in the process of being lowered so the mechanical seal on the mixer can be replaced. Repairs will be completed by the end of the year. A total of less than ten gallons of crude oil leaked from the mixer. Update: on 12/22/2015 the mechanical seal was replaced. On 12/30/2015 the tank was taken out of crude service. As well, please note that current breakout tanks have mixers with compression packing instead of mechanical seals with an isolation device allowing for easier maintenance to be performed.
