A floating spar platform 7 for supporting an offshore wind turbine comprises at least one first ballast tank 15 for holding adjustable ballast and at least one second ballast tank 16 for holding adjustable ballast. The second ballast tank 16 is arranged vertically higher than the first ballast tank 15, allowing a vertical distance between the bottom of the spar platform 7 and the centre of centre of gravity (31, fig 3) of the spar platform 7 to be controlled by adjusting the amount of ballast held within the ballast tanks 15, 16, providing control over the resonant response of the floating spar platform 7. A wind turbine (See fig 1) mounted on the platform.
