HDD boring

The abbreviation HDD stands for horizontal directional drilling. This is a trenchless drilling method that allows underground drilling without disturbing the infrastructure above the ground. Digging trenches is not necessary with HDD boring. As a result, the landscape is preserved, traffic does not experience disruption and there is less contaminated excavated soil.

Besides the low level of disturbance to the landscape above the ground, HDD boring has other advantages. For example, this drilling technique is characterized by its ability to perform long underground drilling trajectories of up to several kilometers. HDD boring also makes it possible to circumvent underground obstacles, such as sewer pipes, cables and other pipelines. And that's important as our underground infrastructure becomes increasingly crowded and complicated.

To perform HDD boring even more accurately, Brownline has developed a steering tool based on gyro technology: the Drillguide Gyro Steering Tool. This tool determines the position of the drill head in real-time during drilling, which is called measurement-while-drilling (MWD).

The information about the position of the drill head is combined with the drilled distance to calculate the displacement of the drill head using our in-house developed algorithms. These insights are analyzed by a professional surveyor, who can adjust the drill head over the desired drilling path. Watch the video below for an example of a drilling project using our Drillguide Gyro Steering Tool.

The Drilllguide Gyro Steering Tool is the basis for our steering services. To complement this advanced tool, we have developed a number of add-on modules that enable HDD boring in various situations. For long and complex drilling, our Radar Intersect and GPS Track add-ons provide the solution. In addition, the UXOscope module allows HDD boring in high-risk areas with unexploded bombs.
