A system of floating and weight-stabilized wind turbine towers with separately floodable compartments and aerodynamic overwater encasement and the appertaining semisubmersible mooring structures including anchorage on the seabed, a horizontally floating underwater mooring meshwork and an actinomorphic buoy-cable-mooring to the wind turbine towers. Also, a method to transport wind turbine towers from the manufacturing plants on-shore to the final off-shore destination by towing the vented towers in a horizontal position with towboats. Further, a method to erect the wind turbine towers at the final destination, including the assembly of the wind turbines. The worldwide potentials of off-shore wind farming in deep waters to produce electricity in an ecologically and economically sound way in order both to satisfy men's requirements and to help to reduce the need to rely on critical fossil and nuclear resources being immense.
System of anchoring and mooring of floating wind turbine towers in waters typically deeper than 30 meters, forming a windpark-structure, comprising:
Method for towing the wind turbine towers with one single or several vented compartments in horizontal position with towboats from on-shore construction and assembling sites to the off-shore sites of electricity production.
Method for erecting wind turbine towers at a final destination by flooding successively one or more compartments, starting with a compartment next to a lower end respectively next to a stabilizing bottom weight of a shaft, until an upper part of each wind turbine tower reaches a working level from which the entire nacelle is mounted to a top end of the respective wind turbine tower and from which also blades are fixed.
