With horizontal directional drilling technology from Herrenknecht, pipelines can be installed rapidly, economically, and with minimized impact on the environment and existing infrastructure. Answering the trend of the pipeline industry towards longer and larger crossings, Herrenknecht´s HDD range has been expanded by new features and technologies such as downhole tooling, the Pipe Thruster as a mobile power reserve, and high-torque Rig versions. Mud handling systems, and breakout units complete Herrenknecht´s HDD portfolio, as well as future-oriented Hybrid and Electro Rig versions and advanced digitalization.
