Flowing waters, roads, or rails can be crossed under with this method. Before any HDD project, a strategic, detailed map is prepared using the information collected from several boreholes to define which type of material will be crossed in every position. This predetermined drill path guides the directional drilling. More specifically, this is how HDD works: a special device is used to drill a small pilot borehole, which is enlarged until adequate size for the cable tube. Then, an empty protection tube is inserted to create a conduit for the wind farm cables, which are pulled through and connected afterward. Boreholes for the cables can be over 3200 feet long and, thanks to innovative technology, can be precisely controlled down to inches. To guide the drilling head, an electromagnetic wave transmitter is used to monitor its exact position every moment. Information, such as position, inclination, temperature, and other important indicators, are transmitted back to the operator. This signal can be read up to a depth of nearly 50 feet. HDD has been successfully used in connection of wind power plants and wind turbines, cabling from land to offshore wind power plants, and cabling from the wind turbines to distribution stations. Though wind farm turbines tower above the earth and sea, the unseen, buried cables are also a vital component of the energy collection and distribution process. Successful transmission of wind-farm-harnessed electricity to the main power grid, and ultimately, to businesses and homes, would not be possible without the unsung heroes of horizontal directional drilling.
