Narrative
On 09/05/2020 at 20:00 local time an enterprise technician was onsite at mcrae terminal when he noticed a leak on the p2 pipeline facility piping. The technician notified pipeline control to shutdown the line and close in all valves which stopped the leak. Upon investigation the source of the leak was found to be a half inch (1/2") failed threaded connection on a thermocouple that broke off the line during operations. Failure was determined to have been caused when a tool struck the probe from the thermowell and damaged the threads on the thermowell probe which was left on the pipe during the tool run. Approximately 200 gallons of diesel had leaked within the facility boundary. The damaged component was removed and a plug placed in the connector. No additional leaks were found and the line was returned to service at 22:04.
