Underwater drilling arrangement for introducing a foundation element into a bed of a body of water comprising:

• a submersible working platform for placement onto the bed of a body of water,
• several ground contact elements, which are arranged in an adjustable manner on the working platform for aligning the working platform on the bed of a body of water, and
• at least one guide pipe arranged on the working platform, which is designed to receive and guide a drilling tool driven by a drill drive, wherein
• the guide pipe is supported in a longitudinally displaceable and rotatable manner on the working platform,
• on the working platform a guide pipe drive is provided for driving the guide pipe in a rotating manner;
• and
• the guide pipe drive has at least one collet drive with a collet, which embraces and clamps the guide pipe, whereby the collet can be twisted around a predetermined angle of twist via at least one twist cylinder arranged transversely to the pipe axis.
