A submersible dynamic floatation tank 21 which is mountable to a base 11 of a wind turbine assembly, may include adjustable buoyancy tanks 26 and 29 and thrusters 25 and 28 operable to adjust the buoyancy, position and attitude of the tank and the base. A method of lowering the centre of gravity of column members 33 and 34 is also disclosed. The column members may comprise a wind turbine mounting, to enable the steps of mounting the column 30 to the base 11 and mounting a nacelle 35 to the column and transporting the base and installing the base resting on a seabed 32 or submerged floating and anchored, using a submersible dynamic floatation tank mounted to the base. The method may include a later step whereby walls of the column members 33 and 34 initially partly of hollow construction are filled with material to form walls of solid construction to enable the delivery of the base and the erection of the column using a submersible dynamic floatation tank. |
