Abstract (en)
[origin: WO2015172818A1] The invention relates to an underwater drilling device and a method for obtaining and analysing soil samples of the bed of a body of water. An underwater drilling device with a base frame is lowered in a body of water and placed on the bed of a body of water. With a drilling drive that is mounted on the base frame and able to move vertically, a drill string consisting of at least one tubular drill string element is drilled into the bed of the body of water in a first drilling step, wherein a core sample is accommodated in a holder in the tubular drill string element. The holder with the core sample is stored in a storage location of a second storage region on the base frame. Subsequently, at least one further drilling step is carried out with a further drill string element. By means of at least one sensor device arranged on a base frame in a surrounding area of the drilling axis, at least one physical and/or chemical property of the core sample is determined. The data thus determined is saved in a data processing device together with data relating to the storage location of the core sample in the second storage region.
