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 of the spar platform 7 to be controlled by adjusting the amount of ballast held within the first and/or second ballast tanks 15, 16. This provides for control over the resonant response of the floating spar platform 7. During installation of a wind turbine on the floating spar platform 7, ballast associated with the spar platform may be adjusted in order to increase the vertical distance between the bottom of the spar platform 7 and the centre of gravity 31 of the spar platform 7, which reduces wave-induced resonant motions of the spar platform 7.
