Narrative
On november 5, 2019 at 10:35 cst an explorer pipeline employee was removing 0.25-inch stainless steel tubing that was buried approximately 18-inch underground as part of a station integrity improvement project. The valve and compression fitting were visible, but they were contained inside a metal encasement that was approximately 18 inches below grade. Approximately 4 feet of buried stainless-steel tubing extended 90 degrees underground from the metal encasement. In conjunction with integrity management facility improvements, during a tubing removal process, force was applied to remove underground stainless-steel tubing and a crack was experienced in the valves 0.75 to 0.25 reducer threaded fitting. Testing confirmed the fitting was seized due to incorrect installation from a previous operator, but unknown to the employee. To avert future potential risks related to this incident, explorer pipeline is incorporating tubing removal as an operator qualification (oq) covered tasks. A revised procedure is currently undergoing a final review in the management of change (moc) process.
