Narrative
On 4/4/17, company personnel were working to align the surge tank reinjection pump at redfield station as some vibration had been identified during the line/station commissioning process. While this work was in progress the reinjection pump began to vibrate excessively which led to failure of the pump rotor discharge housing resulting in a release of approximately 2 bbls of crude oil before the unit could be manually shutdown. All released product was contained on the synthetic material lined containment area and immediately cleaned up. The excessive pump vibration was investigated and confirmed to have been caused by misalignment and hydraulics dynamics from pump discharge against a pressure head. The pump was replaced by the manufacturer and other same manufacturer and model pumps installed in the system were checked for similar circumstances. To reduce the probability of a repeat failure at this location and others with same manufacturer and model pump, the automatic start controls were removed so that pumps could only be operated manually and while at least one mainline unit is operating. This will ensure pressure head will be avoided, visual contact with pump is maintained and that pump could be shut down quickly to avoid failure if vibration began.
