Abstract
A method for producing an underwater foundation element in a bed of a body of water, in which a working platform for guiding a drilling tool is lowered to the bed of a body of water, so that a drill-hole is introduced into the bed of a body of water and a pile-shaped underwater foundation element is arranged in the drill-hole and anchored therein. A precise alignment is achieved in that on the pile-shaped underwater foundation element a measuring unit is fixed, through which positional data of the pile-shaped underwater foundation element are determined and in that depending on the determined positional data the position of the underwater foundation element is set by at least one positioning means on the working platform prior to anchoring. The measuring unit is arranged on an adjustment head.
