Narrative
On april 25, 2015 tank 3512 and 3513 had tank mixer seal failures (one mixer per tank). The seal failures resulted in 10 bbls of crude oil (wti) being released from the two tanks. The crude oil was released to the tank dike containment and tanks remained out of service until repairs could be completed. Jensen mixers international performed an analysis of the seal failures and determined the cause of the failure to be solid material from the crude entered the seal and causing abrasion. Along with the abrasion, potentially upon restart of the mixers, the foreign material created enough friction that caused a failure of the carbon components. The seals were replaced with bronze/tungsten components to improve wear and prevent future failures.
