Support structure floating in the open sea and connected to anchors by bracing means, for wind turbines, service stations or converter stations

Support structure (2) floating in the open sea and connected to anchors by bracing elements, for wind turbines (1), service stations or converter stations with

• a first component (3) arranged under water with first buoyant bodies (5) arranged at corner points of a polygon, extending perpendicular to a plane and serving as carriers of a second component (4) cutting through the surface of the water and second buoyant bodies (6) connecting the first buoyant bodies (5) with one another, arranged in a plane and having a tube-shaped design, wherein a nodal structure (7) with a multi-prong-shaped base area that connects at least two second buoyant bodies (6) with one another and at least one junction plate (8) in contact with the nodal structure (7), designed in the shape of a U and perpendicularly dividing the first buoyant body (5) in certain sections are arranged in the first buoyant body (5), and the nodal structure (7) is simultaneously the carrier for a tube-shaped support element (9) cutting through the surface of the water and is therefore, in connection with the junction plate (8), a node of the underwater support structure (3) that absorbs and channels along forces, and
• the second component (4) with tube-shaped support elements (9) cutting through the surface of the water on the first buoyant bodies (5), which are connected via support gear (10) to a foundation structure (11) for the wind turbine (1), the service station or the converter station.
