Claim 14:
15. The method according to claim 14, wherein said method is developed in a dock-factory that includes four areas which make up an industrial production line, each of which comprises:
a) a previous area, wherein an auxiliary pontoon is arranged, with dimensions somewhat larger in layout than those of the slab of the platform, wherein the pre-assembly of the rebar of the slab is performed;
b) a first area, wherein a submersible pontoon with dimensions somewhat larger than those of the auxiliary pontoon that supports the rebar of the slab is arranged, to which the rebar of the slab as a whole is passed, leaving it previously suspended and separated from the auxiliary pontoon, in order to then remove it and replace it with the main pontoon, whereon the rebar is finally deposited, ready to proceed to the installation of the formworks of the slab and the concreting thereof and that of the cylinders up to an intermediate height, all of this as the submersible pontoon descends, maintaining the concreting area above the water level at all times;
c) a second area, to which the platform is transferred once the submersible pontoon which fully supported it has been sunk, until the platform is left floating, then being towed to this manufacturing area, wherein the platform under construction remains floating and is sunk gradually as the concreting of the cylinders and the placement of the metal elements which make up the upper covers thereof continue; and
d) a third area, to which the platform is transferred by floating and pulling it from a tugboat, wherein the seabed has been levelled and has a draft such that when ballasting the platform it remains supported on the seabed in a semi-submerged position, in arrangement to then install the rest of the metal superstructure, the tower, the nacelle, the rotor and the blades of the wind turbine by means of an overland crane located on the dock, while the deballasting of the cylinders is progressively carried out so that, once the assembly process is completed, the platform remains afloat, completely constructed and ready to be towed to the installation site thereof in deep water.
