24″ Crude Oil Transmission Pipeline Cathodic Protection Design and Commissioning

Coffman provided design, construction support, and commissioning services for an impressed current cathodic protection (CP) system to protect a new 140-mile long, 24” diameter crude oil transmission pipeline, pump station, and remote valve sites throughout Wyoming and Colorado.

The cathodic protection test station design included two-wire test stations, foreign crossing test stations, and junction boxes. The impressed current cathodic protection design included multiple rectifiers energizing deep anode groundbeds, remote monitoring units, bonding provisions, and electrical isolation consulting. Construction support services included on-call and field support during the installation of test stations, impressed current CP systems, and AC mitigation systems. Commissioning services included CP surveys, system balancing, evaluation of stray current, remote monitoring unit configuration, and a comprehensive final report.
