In summation, the invention is a design to connect float modules (2) to each other and/or to assembly units and/or to the superstructure. In a preferred embodiment, the invention is applied for pontoons (1) constructed of concrete float modules (2), where prismatic float modules (2) minimally include a monolithic upper plate (3), side walls (4) and/or frame units (6) arranged along the edges (5) of the float module (2) and float modules (2) are fixed to each other by means of longitudinal tension units (15) led through said float modules (2). For tension units (15), boreholes (8) are created in the side walls (4) or the frame units (6) of the float module (2) minimum at the edges (5) of the upper plate of the prism, intersecting the prism and running parallel with the edges (5). In particular cases, directional recesses (14) are created around the exit holes (9) of boreholes (8) with skew axes (Tx, Ty, Tz), running in different directions and meeting in the corners of float modules (2). Into the directional recesses (14) between the float modules (2), resilient directional spacers (16) are inserted. Directional spacers (16) have boreholes that contain the relevant tension units (15). In present invention, at least the surfaces with the boreholes (8) for the tension units (15) are equipped with rigid corner elements (11) at the corners of the float module (2) where the impact resistance and compressive strength of the material of the corner elements (11) exceed those of the material of the float module (2); boreholes (13) are created for the exit holes (9) in the corner elements (11); the directional recesses (14) sunk into corner elements (11) are shaped as truncated cones tapering inwards and the envelope of directional spacers (16) has the same shape as that of the directional recess (14), two truncated cones with their bases facing each other.

A wind turbine platform configured to float in a body of water and support a wind turbine thereon includes a buoyant hull platform. A wind turbine tower is centrally mounted on the hull platform and a wind turbine is mounted to the wind turbine tower. An anchor is connected to the hull platform and to the seabed, and a weight-adjustable mass is suspended from the hull platform.
