The Overland Pass Pipeline (OPPL) is a 760-mile natural gas liquids (NGLs) pipeline extending from Wyoming to Kansas. Currently, it transports 140,000 barrels per day of NGLs. A 15-mile corridor in rural Wyoming runs parallel to a 235 kV overhead transmission system. The alignment of these two systems has the potential to lead to accelerated corrosion of the pipeline. Kleinfelder was contracted to perform an alternating current (AC) interference investigation and modeling for this corridor.
Kleinfelder’s experience in pipeline integrity management, proactive communication, and sophisticated modeling software resulted in a successful mitigation plan for the corridor. Utilizing an advanced software program and streamlined processes, Kleinfelder decreased turnaround time for analysis of findings from 60-90 days to within 45 days, despite location challenges.
