Abstract
A wind turbine includes a floating foundation having a plurality of buoyancy bodies, the buoyancy bodies being formed from a plurality of buoyancy body elements designed as hollow bodies, which are arranged adjacent to one another in a first plane concentrically around each central element extending from the floating foundation and are connected to said central element. Each buoyancy body element has a surface supported on the central element, a convex surface arranged opposite the central element, and two lateral surfaces each supported on a lateral surface of an adjacent buoyancy body element.

A wind turbine comprising
- a floating foundation having a plurality of buoyancy bodies, wherein
- the buoyancy bodies are formed from a plurality of buoyancy body elements in the form of hollow bodies, which buoyancy body elements are arranged next to one another in a first level concentrically around a relevant central element that extends from the floating foundation, and are connected to said central element, and
- each buoyancy body element has a surface supported on the central element, a convex surface arranged opposite the central element, and two side surfaces each supported on a side surface of an adjacent buoyancy body element, wherein an outer wall forming the convex surface has a greater wall thickness than walls forming the side surfaces.
A wind turbine comprising
- a floating foundation having a plurality of buoyancy bodies, wherein
- the buoyancy bodies are formed from a plurality of buoyancy body elements in the form of hollow bodies, which buoyancy body elements are arranged next to one another in a first level concentrically around a relevant central element that extends from the floating foundation, and are connected to said central element,
- each buoyancy body element has a surface supported on the central element, a convex surface arranged opposite the central element, and two side surfaces each supported on a side surface of an adjacent buoyancy body element, and
- at least one further level of buoyancy body elements arranged below the first level, which buoyancy body elements are arranged around a relevant central element and are connected to said central element, wherein the buoyancy body elements arranged in the further level are designed so as to have thicker walls than the buoyancy body elements arranged in the first level.
