Narrative
Oneok pipeline control center received a gas detect alarm at the oneok red river pump station at approximately 3:03 am on september 23rd, 2017. The pump station shutdown once the gas detect activated. Pipeline control contacted the local area representative and dispatched him to the site. Upon arrival the oneok employee identified an ice ball on the side of some 1/2" stainless steel tubing used as a seal flush line on the pump. The tubing was isolated and removed and replaced with new tubing. Once the ice ball had thawed it was determined the tubing wall had cracked on the side of a bend. Tubing had been in place since the pump station had been commissioned (2007). All of the stainless steel tubing in the pump station and no other indications of cracks were identified. Once the tubing had been replaces and the gas detection alarms were reset the station was returned to normal operation.
