This study demonstrates the feasibility of using an extendable probe rod tool to install a diagnostic reference electrode coupon assembly at an existing cathodic protection test station. Traditional installation methods—such as mechanical excavation (with a backhoe or auger) and vacuum excavation (via wet-vac or air-hammer)—require multi-person crews, heavy equipment, permits, and extensive coordination. These methods are often costly, logistically complex, and pose safety and environmental concerns, especially in remote or sensitive areas. The proposed method offers a streamlined alternative. By using an extendable probe rod tool, a small-diameter pilot hole is driven to pipeline depth, allowing for precise insertion of a compact reference electrode coupon assembly. This approach eliminates the need for excavation and can be performed by a single technician with minimal preparation and surface disruption. The simplicity and efficiency of this method reduce both cost and time, while enabling immediate data acquisition critical for assessing cathodic protection effectiveness. Its portability and minimal environmental impact make it especially valuable for rapid deployment in locations where traditional methods are impractical. Ultimately, this technique supports more responsive and cost-effective monitoring and maintenance of cathodic protection systems. The probe rod installation method is protected under United States Patents 11,447,877; 11,807,945; and 12,043,906.
