Narrative
On 7/31/2019 at approximately 10:42 am, local operations employees were cleaning up from a previous maintenance activity they were performing on the sasol-na1-tx-6" ethane line at the lone star ngl facility when they heard a leak coming from the door of the pig trap. Local operations immediately called the lone star outside operator who immediately turned on local fire monitors around the area of the pig trap to suppress the ethane vapors, and the emergency response procedures were initiated. All internal and external notifications were made. The pig trap was removed, blinded, and shipped to dnv to further investigate the cause of the release on the threaded pig trap door. The root cause of the incident was determined to be equipment failure. The results of the analysis indicate that the leak occurred due to the failure of an o-ring. The o-ring failed as a result of mechanical damage in the form of pinching that occurred during installation.
