Abstract (en)

[origin: EP2407629A1] The apparatus has a drilling device with a support frame having a fastening device for fastening the drilling device opposite to a jacket tube, and drilling tools i.e. drill buckets, rotatably driven by a telescopic linkage using a drilling drive arranged in the frame. An emptying station (20) is attached to an upper end of the jacket tube, and the frame is fastened at the station, where the station has an unloading device (25) for removing the tools from drill cuttings. The unloading device is adjusted for retaining the drill cuttings and discharging the drill cuttings from the station. An independent claim is also included for a method for drilling a hole inside a jacket tube.
