  • a buoyancy body for floating support of a buoyant structure, wherein the buoyancy body is essentially designed in the form of a cylinder or regular prism. Accordingly, the buoyancy body has a base surface and a top surface, which are aligned essentially perpendicular to an axis of symmetry of the buoyancy body. A lateral surface of the buoyancy body, which encloses the axis of symmetry, is arranged between the base surface and the top surface.
  • Recesses are formed in the top surface in order to be able to positively accommodate a node point of a substantially flat, truss-like base structure perpendicular to an axis of symmetry of the buoyancy body, fixing elements being provided for fixing the truss-like base structure in the direction of the symmetry axis, so that the Buoyancy body can be firmly fixed to the node point in all 6 degrees of freedom.
  • the truss-like base structure is thus fixed by inserting it into the recesses of the buoyancy body according to the invention in the plane perpendicular to the axis of symmetry of the buoyancy body (and parallel to the deck surface) and is therefore fixed in 3 degrees of freedom.
  • These defined degrees of freedom include a translational movement perpendicular to the axis of symmetry of the buoyancy body and a rotation about the axis of symmetry of the buoyancy body.
  • the fixing means additionally fixes the position of the base structure in the direction of the axis of symmetry, thereby preventing a translational movement in the direction of the axis of symmetry as well as a rotation in one of the two remaining directions of rotation.

  • Two buoyancy bodies arranged one above the other in the direction of their axes of symmetry can be fixed in a plane perpendicular to the axis of symmetry by the base structure lying between them.
  • part of the base area of the buoyancy bodies can be designed to be complementary to their top surface, so that two buoyancy bodies can be arranged one above the other in a rotationally secure manner in the direction around the axis of symmetry, even if no frame-like base structure is arranged between the buoyancy bodies .

  • the torsional rigidity of the base structure is increased by the diagonal bracing using the tension connectors. This reduces the load to which sensitive components that are supported by the base structure are exposed, and damage that could be caused by deformations of the base structure to the sensitive components, such as photovoltaic panels, can be reduced.
