Tief4 consortium

Amprion commissioned the Tief4 consortium to carry out early onshore construction works for the DolWin4 offshore grid connection, starting with installation of a cable protection pipe system into which the power cables would later be pulled. The scope included pre-welding of pipe strings and installation using both closed construction methods (primarily horizontal directional drilling) and open construction methods along the onshore route toward the converter station in Lingen.
