Abstract: A wind turbine, having a floating foundation (1), a support structure (2) and a generator (3). The generator (3) is an up-wind generator. The floating foundation (1) is assembled from tubular steel sections (5, 6, 7, 8) of uniform diameter, forming a frame with a mooring turret (4) at one corner. The support structure (2) hays at least two beams (11, 12) extending substantially transverse to the floating foundation (1). The beams are connected at a first end to a respective opposite side of said foundation frame and at a second end to said nacelle (17). The support structure (2) and the floating foundation (1) form a triangle with the nacelle (17) fixedly mounted at the apex. The support structure (2) comprises tensioned backstays (13, 14, 15, 16) supporting the beams (11, 12) and ensuring that they are substantially subjected to compression forces only.
