1. 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 of the radial arms carrying an outer stability tower, the method comprising:
prefabricating the radial arms, central connector and at least parts of the central and outer stability towers,
pre-assembling the central connector with one arm to form a primary pre-assembly,
mounting temporary flotation devices onto the radial arms to provide additional buoyancy to the radial arms,
floating the primary preassembly and floating the other arms of the floater,
assembling offshore said primary preassembly with said other arms.
