摘要

A device and method for lifting, transporting, positioning and installing at least one marine structure (20), especially one or more windmills, with the help of a ballastable lifting vessel (1), comprising a lower pontoon foundation (2) with longitudinal pontoons (2c, 2b), and a transversal pontoon (2c), a number of columns (5) which are connected to the pontoon foundation (2) and which extend up-wards, i.e. towards and through the water surface. The device comprises at least one lifting support structure (10) arranged on the pontoon foundation (2) and which can be inclined towards the vessel's dock area(s), and the lifting/support structure (10) in the form of a tilting device (11) with an arm (13) which can be connected to the marine structure (20) and which can move and lock it in any desired position.
