The project, which began with Triangle Communications in Havre, Montana, as part of a broader regional fibre upgrade, quickly proved to be more complex than initially anticipated. The scope appeared straightforward on paper, but field conditions soon revealed their true nature. Spring runoff was the biggest challenge, with the river roaring and locating across it proving to be tough.
The crew needed to complete two crossings, each spanning hundreds of feet beneath the river, making traditional walkover locating an impossible task. With more than 500 feet separating entry and exit points, holding position long enough to gather accurate data simply wasn't feasible. Tracking from a boat was considered but quickly dismissed due to the strength of the current.
The team devised a different solution, utilizing a pulley system anchored to a nearby bridge to suspend a Subsite Marksman+ HDD locator roughly 60 feet above the river. From this elevated position, the locator maintained a clear signal path to the drill head moving beneath the riverbed. Operators controlled the locator from both banks, moving it across the span to monitor pitch, signal strength, and drill head location throughout the bore.
The setup required multiple attempts to secure the cable across the river, with wind, spray, and strong currents making it difficult to achieve proper tensioning. Once in place, however, the system provided the consistent locating data needed to guide the operation safely. The use of this elevated locating system demonstrates the importance of adaptability in drilling operations.
Crossing more than 600 feet under a river requires a high level of confidence in both the equipment and the crew. Having the right locating technology in place makes it possible to maintain control and visibility throughout the shot. This project showcases the capabilities of advanced HDD technology in navigating complex environments.
