Revolutionary Magnetic Guidance Systems Transform Directional Drilling Safety on Long Island
Long Island’s underground landscape resembles a complex maze of utilities accumulated over decades of infrastructure development. With decades of infrastructure development across Nassau and Suffolk Counties, the ground beneath our feet contains a complex web of water lines, sewer pipes, electrical cables, gas lines, and telecommunications equipment. In this congested environment, traditional drilling methods carry significant risks of costly utility strikes, but advanced magnetic guidance systems are revolutionizing how contractors navigate these underground networks with unprecedented precision.
The Challenge of Long Island’s Underground Networks
When you need new plumbing services, the last thing you want is a costly utility strike that could leave your neighborhood without power or water for days. The density of Long Island’s underground infrastructure presents unique challenges that require sophisticated navigation solutions. Properties are dense, roads are narrow, and nearly every residential block has a network of utilities running in multiple directions underground.
The risks extend beyond simple inconvenience. Cross bores between gas/electric lines and sewer lines create potentially dangerous situations where homeowners or plumbers could inadvertently sever lines while clearing blockages, causing injury or death. This reality underscores the critical importance of precise navigation technology in modern directional drilling operations.
How Magnetic Guidance Systems Work
Modern magnetic guidance systems represent a sophisticated fusion of multiple technologies designed to provide real-time positioning data during drilling operations. Sharewell’s Magnetic Guidance System (MGS) is a directional steering system that provides real time information for the Horizontal Directional Drilling Industry. The MGS provides the contractor with known positioning by producing immediate information on tool face, azimuth (horizontal angle) and inclination (vertical angle).
The technology addresses fundamental challenges that have plagued traditional guidance methods. In order to solve the problems of existing horizontal directional drilling (HDD) guidance methods, including low measurement accuracy, shallow positioning distance, discontinuous measurement data and great interference by magnetic field, a magnetic beacon-based horizontal directional drilling guidance and positioning method was proposed to achieve the position and attitude measurement of HDD.
Advanced systems utilize sophisticated measurement arrays that can eliminate environmental interference. Meanwhile, a measurement array based on the third-order magnetic gradient tensor was designed, which verifies through simulation that the method could eliminate the influence of the geomagnetic fields and achieve the position measurement.
Real-Time Navigation and Precision Control
The effectiveness of magnetic guidance systems lies in their ability to provide continuous, accurate positioning data throughout the drilling process. The transmitter sends signals with downhole information to a receiver carried by the locator walking the surface along the bore path, allowing the locator to determine drill bit location, depth, direction, progress speed, and steering face position to advise direction changes. Communication between the locator and rig operator ensures immediate adjustments when needed.
This real-time feedback enables operators to make precise course corrections, maintaining safe clearances from existing utilities. Modern HDD rigs use guidance systems that allow the operator to track the drill head’s position in real time as it bores underground. The level of accuracy is quite high — experienced operators can steer the drill along a planned path and hit a target point within inches.
Preventing Utility Strikes Through Advanced Technology
The integration of magnetic guidance systems with comprehensive utility locating protocols creates multiple layers of protection against utility strikes. Before any bore begins, we require utility marking through 811 (New York’s Dig Safely NY service) so all known underground utilities in the work area are located and flagged. We incorporate those locations into our bore path planning to maintain safe clearances. Our operators monitor the drill head’s position throughout the bore and adjust as needed.
The technology proves particularly valuable in Long Island’s challenging environment. Trenchless methods actually reduce the risk of utility strikes compared to open excavation because the drill path is controlled and precise. Traditional digging involves heavy equipment breaking ground across a wide area, which increases the chance of hitting something.

The Future of Safe Underground Construction
As Long Island’s underground infrastructure continues to grow more complex, magnetic guidance systems will become increasingly essential for safe, efficient directional drilling operations. The research results could improve the applicable range, real-time performance and positioning accuracy of trenchless horizontal directional drilling, thereby providing the theoretical basis for the automation of HDD guidance technology.
Recent advances show remarkable precision capabilities. The results show that the error is within 0.3° for the inclination angle, within 0.7° for the tool face angle, and within 1° for the azimuth angle. This indicates the accuracy and effectiveness of the position measurement algorithm based on the third-order magnetic gradient tensor and the attitude measurement algorithm with multi-source data fusion proposed in this paper.
For Long Island property owners, this technology represents more than just technical advancement—it means safer, faster utility installations with minimal disruption to daily life and existing infrastructure. As these systems continue to evolve, they promise to make Long Island’s underground construction projects both safer and more efficient than ever before.
