An offshore wind turbine system is assembled using a platform (40, fig 7) or jack-up vessel, and a first base 32 anchored to the seafloor at a blade assembly offshore location. A buoyant tower 10 is attached to the first base. A crane (42, fig 7) provided on the platform or jack-up vessel is used to lift blades 36, which are then coupled to a turbine 30 held in a nacelle provided at the top of the buoyant tower. The buoyant tower, the nacelle, and the blades are detached from the first base. The buoyant tower, the nacelle, and the blades are towed (fig 8) to a wind farm and connected to a second base 12a, 12b, 12c provided in the wind farm. The buoyant tower, the nacelle, and the blades are further stabilized using mooring lines 14 spanning between the buoyant towers 10a, 10b, 10c and other bases provided in the wind farm. The first base and/or the second base include anti-rotation features (22, fig 2b & 3b).
