Narrative
On 4/26/18, a pipeline rehab crew was excavating an dig location near mp 167.7 on the tcs tulsa to sheldon #3-12". The dig was located between a mainline gate valve and a road way. The inline inspection data indicated fittings were located on each side of the mainline gate valve. The fitting on the south side was located and exposed while performing the excavation. Since the anomaly was located south of the valve, no excavation activity was planned on the north side of the valve. The tracked excavator was staged on the north side of the mainline gate valve, with the excavator tracks perpendicular to the line to allow access to the excavation. At the time of excavation, soil conditions were wet. As the excavator was digging, the excavator slid on the soft soil and either displaced soil or made direct contact with the fitting on the north side of the valve causing the release. The vertical fitting was found to be comprised of multiple components and failed at the threaded fitting of one of the components. The chief inspector notified operations control and a code red was issued. Personnel were dispatched to close mainline gate valves and isolate the line section. Soil berms were placed in the roadway ditch to prevent the release from migrating. Emergency responders arrived and closed the highway. Vac trucks recovered free product from the area and impacted soil was excavated and properly disposed. 400 cubic yards of soil were hauled to the waste management non-hazardous landfill in tulsa, ok. The damaged fitting was removed from the pipeline and a thread-o-ring nipple was installed.
