Narrative
On may 4, 2020, at approximately 9:00 pm the control center notified the white cliff oklahoma area manager of an lel alarm on pump 1 at deer creek station near lamont oklahoma. The control center then shutdown and isolated the station remotely using movs and the station was placed in bypass mode. The area manager called out a pipeline operator to investigate the lel alarm. The pipeliner arrived on location at approximately 9:50 pm to discover an ice ball and vapor cloud located near the top of the check valve on the 12-inch piping near pump 1. The operator notified his manager of the air release. Lels were monitored throughout the facility and a risk assessment was completed. The personnel on site worked to isolate the station pump piping further by closing the upstream valve on the receiver trap and downstream valve of the launch trap. Starting at 11:45 pm the pipeliner began sending ngl from the pump piping to the maintenance flare to reduce pressure on the piping and reduce vapor release. The flare was ignited at 1:00 am on may 5, 2020, was manned, and continued operation until 7:00 am may 6, 2020. At 7:30 am on may 6, 2020 the flare down was complete and the station piping was displaced with nitrogen to allow for the bonnet of the check valve to be inspected. It was determined that the o-ring had failed due to improper installation. The o-ring was removed and replaced. The bonnet of the check valve was torqued to specifications and the station was flooded with ngl and returned to normal operation at approximately 4:30 pm on may 6, 2020.
