Abstract
A method for constructing a wind turbine concrete floater including a central connector from which radial arms extend, the central connector carrying a central stability tower, and each arm carrying an outer stability tower. The method includes prefabricating the arms, central connector and at least parts of the stability towers, pre-assembling the central connector with one arm to form a primary pre-assembly, mounting temporary flotation devices onto the arms to provide additional buoyancy to them, floating the primary preassembly and floating the other arms of the floater, and assembling offshore said primary preassembly with said other arms.

A method for constructing a wind turbine concrete floater comprising a central connector from which radial arms extend, the central connector carrying a central stability tower, and each arm carrying an outer stability tower, the method comprising:
- prefabricating the arms, central connector and at least parts of the stability towers,
- pre-assembling the central connector with one arm to form a primary pre-assembly,
- mounting temporary flotation devices onto the arms to provide additional buoyancy to them,
- floating the primary preassembly and floating the other arms of the floater,
- assembling offshore said primary preassembly with said other arms.
A system comprising:
- a concrete floater comprising at least three radial arms fixed to a central connector,
- additional flotation devices each configured to be mounted on a corresponding arm and serving to provide additional buoyancy during off shore assembly of at least two arms to a primary preassembly of another arm with the central connector, each additional flotation device preferably comprising retractable lower corbels and two symmetrical parts to be assembled over the corresponding arm.
