The whole trilling equipment is arranged to turn in a plane parallel to the plane of the brackets of the dredger's boom, and the drilling machine itself together with its drill- propulsion unit is arranged to turn in a plane perpen- dicular to said brackets plane. These turnings are preferentially effected by hydraulic power from the dredger.
