Narrative
At approximately 2:54am on september 11th, pump 651 at the oneok west winfree facility was automatically shut down by a gas detect alarm. A oneok operator arrived on site at approximately 3am to investigate. A visual and audible inspection accompanied with a personal gas monitor check found no hydrocarbons in the area. The pump was restarted at approximately 3:11am at which time the operator noticed a small release coming from a 1" nipple on the piping near the pump. The pump was immediately shut down blocking in the affected piping to the 1" nipple at which time the operator began flaring that section. After the piping was evacuated of hydrocarbons the 1" nipple was inspected and found to have a small crack in the threads which caused the release. The nipple was removed, replaced and the pump returned to service. Remediation measures: the affected nipple setup includes a 1" valve, 90, and check valve. It has been determined that the 90 and check valve can be removed to reduce additional stress on the nipple. We will also verify the system to ensure similar nipple setups are removed. In addition, affected personnel will be given refresher training on the trrc requirements for immediate telephonic notice for incidents or accidents on intrastate hazardous liquid pipelines reportable under 49 cfr sections 195.50 and 195.52 and 16 texas administrative code, chapter 8 update 1/9/2020 (marlon cockerell) oneok is in the process of making the remediation changes to the valve setup. Expected completion is 2/28/2020. Trrc has approved oneok's planned refresher training with a required completion date of 2/1/2020. As of this update all affected employees have completed the refresher training. Update 2/12/2020 (marlon cockerell) oneok pipeline received a letter from the trrc, dated 1/17/2020, accepting the completed refresher training.
