DESCRIPTION OF A PREFERRED EMBODIMENT
25 As shown in the schematic representation of Figure 1, the manufacturing procedure of a marine floating platform, suitable for the arrangement on it of an electric wind turbine, comprises the following steps:
to.
Assembly 10 of consecutive and adjacent 30 flotation elements between them.
b.
Assembly added 20 to the previous assembly 10 of flotation ends, obtaining at least two resulting floats 1 substantially equal.
C.
Union 30 of the above floats 1 with a bracing structure 2.
d.
Positioning and fixing 40 of a wind turbine tower 3 in floats 1 and / or in 35 the bracing structure 2.
As shown schematically in Figure 2, in this preferred embodiment, such flotation elements are cylindrical segments 4 constructed of concrete, which are constructed in an upright position to facilitate concreting and reuse of formwork.
The cylindrical segments 4 have the same diameter, and are substantially similar to each other.
Likewise, the flotation ends, in this preferred embodiment, are of substantially conical configuration, by way of cones 5, and also constructed in concrete and in an upright position to facilitate concreting and reuse of formwork.
The construction of the flotation elements and the flotation ends is carried out prior to the start of the manufacturing process of a offshore wind platform of the present invention, following some procedure known in the current state of the art.
As can be seen in the schematic representation of Figures 1 and 3, first an assembly 10 of the consecutive flotation elements is made and adjacent to each other, and then another added assembly 20 is made with the flotation ends, resulting in obtaining of some floats 1.
In this preferred embodiment, since the flotation elements are cylindrical segments 4 and the flotation ends have a substantially conical cone-shaped configuration 5, its assembly 10 and subsequent added assembly 20 results in floats 1 of substantially configuration cylindrical and equal between them, and built in reinforced concrete with longitudinal prestressing.
Next, as shown schematically in Figures 1 and 4, a connection 30 of the floats 1 is made to a bracing structure 2, so that the two floats 1 are in a parallel and symmetrical position between them, and the bracing structure 2 in an intermediate position between them.
Next, positioning and fixing 40 of a wind turbine tower 3 is carried out on the floats 1 and in the bracing structure 2, obtaining as a final result the offshore wind platform, as it is represented and sequentially in figures 5, 6 and 7 .
In the preferred embodiment schematically represented in Figures 5, 6 and 7, the positioning and fixing 40 of a wind turbine tower 3 in the floats 1 and in the bracing structure 2 is carried out by means of an auxiliary structure 31.
In this preferred embodiment, after positioning and fixing 40 of a wind turbine tower 3 in the floats 1 and in the bracing structure 2, an arrangement 50 is made in a liquid medium (usually in a marine environment) of the floats 1 attached to the bracing structure 2, as schematically represented in Figure 8.
In other preferred embodiments, the arrangement 50 in a liquid medium of the floats 1 attached to the bracing structure 2, can be carried out before positioning and fixing 40 of the wind turbine tower 3 in the bracing structure 2, taking place by both the positioning and fixing 40 of the wind turbine tower 3 with the floats 1 already in a floating situation.
In another preferred embodiment, after joining 30 of the floats 1 with the bracing structure 2, flat surface elements 7 oriented along the longitudinal axis thereof and by way of wind rudder can be fixed on the bracing structure 2 .
In other preferred embodiments, the offshore wind platform may include a counterweight that provides adequate stability in its flotation.
In such cases, the construction of such a counterweight must be carried out, the construction process of which is not the subject of the present invention.
In such preferred embodiments, as schematically represented in figure 9, the positioning and fixing operation 60 of such counterweight is carried out in
dry, after attachment 30 of the floats 1 to the bracing structure 2, and before arrangement 50 in a liquid medium.
As shown in Figures 9, 10 and 11, the floats 1 and the structure of
5 bracing 2 are placed in an inverted position, proceeding after positioning and fixing 60 of such counterweight (in this embodiment represented by a volume 6 concrete) to arrangement 50 of the floats 1 in a liquid medium, and then to his turn 70.
10 As shown schematically in Figures 10 and 11, in some preferred embodiments, positioning and fixing 60 of such counterweight can be performed with the aid of an auxiliary system 61.
In this preferred embodiment, flipping 70 is carried out by ballasting.
15 or internal flooding of one of the floats 1 with water, finally, after removing the water ballast, leave the counterweight in a lower normal position, as shown schematically and sequentially in Figures 11, 12 and 13. Figures 12 and 13, the part that is below the water line is not represented.
20 In this preferred embodiment, the positioning and fixing 40 of the wind turbine tower 3 is carried out with the floats 1 already floating, after turning 70, as shown schematically in Figures 9 and 14. In Figure 14 , the part that is below the water line is not represented.
As a result of the process of the present invention, a resulting offshore wind platform is obtained.
Such offshore wind platform comprises at least two floats 1, a bracing structure 2, and a wind turbine tower 3, as can be seen and represented.
30 schematically in figures 8 and 14.
In this preferred embodiment, two floats 1 are constructed of reinforced and prestressed concrete that are substantially cylindrical, parallel and in a symmetrical position between them, and are similarly and simultaneously connected to the bracing structure 2, which is
35 in an intermediate position between them.
The interior of the floats 1 is enabled to be able to house water inside, in order to carry out its flooding of ballast and subsequent emptying, in the flipping operation 70 described above.
In other preferred embodiments, the wind turbine tower 3 is positioned and fixed in the floats 1 and in the bracing structure 2 by means of an auxiliary structure 31.
In another preferred embodiment, the marine floating platform comprises flat surface elements 7 fixed thereto to aid in its proper alignment with the wind direction, thus acting as a wind rudder, as schematically shown in Figure 15.
In another preferred embodiment, the offshore wind platform comprises a counterweight properly positioned and fixed to the floats 1 and / or to the bracing structure 2. In this preferred embodiment, the counterweight is a volume 6 of concrete, such as It is schematically represented in Figure 14, and is positioned and fixed in the floats 1 and in the bracing structure 2 by an auxiliary system 61.
The offshore wind platform may be part of a wind energy harvesting system.
As shown schematically in Figures 16 and 17, said wind power utilization system comprises the offshore wind platform and also a holding buoy 8 and electric transmission of the platform itself.
Buoy 8 has anchoring means on the seabed, rotating means for electrical connection to the platform, and rotating means for mooring the platform.
In this preferred embodiment schematically represented in Figures 16 and 17, the anchoring means on the seabed are made by three anchor lines 9 with their corresponding anchors, concrete blocks and / or piles for fixing to the seabed.
The rotating means of electrical connection with the platform allow the platform, 5 by the action of the current and the sea waves, to move around the buoy 8 and transmitting without interruption the generated electric current.
In this preferred embodiment, the rotating electrical connection means are made by a rotating connector 10, enabled for the electric transmission cable 11
10 which crosses the buoy 8 along its vertical longitudinal axis from the seabed to reach the platform, so that although the platform moves around the buoy 8, the electric transmission cable 11 continues to be properly connected to the platform.
In other preferred embodiments (not shown in the drawings), the connector
Swivel 15 could even be located on the platform itself, also allowing even if the platform moves around the buoy 8, the electric transmission cable 11 continues to be properly connected to the platform.
The rotating platform mooring means comprise a rotating connection 12 to the
20 that the moorings 13 of the platform are joined, so that the rotation of the platform around the buoy 8 does not affect either the buoy 8 or its anchoring lines 9.
The details, shapes, dimensions and other accessory elements, as well as the materials used in the manufacturing process of a offshore wind platform,
The resulting platform and wind energy utilization system of the invention may be conveniently replaced by others that are technically equivalent and do not depart from the essentiality of the invention or the scope defined by the claims set forth below.

- Assembly of elements of consecutive flotation and adjacent to each other. - Assembly of the ends of the flotation elements, resulting in at least two equal floats. -Union of the floats with a bracing structure. -Positioning and fixing of a wind turbine tower.
Documents D01 and D03, however, do not expressly disclose a manufacturing method, they do disclose the technical characteristics of the resulting platform indicated by the procedure of claim 1. The claimed stages are a simple statement of modules or parts of the platform without that none of them confer on the procedure any technical improvement or any surprising technical effect, for which reason claim 1 is considered as a mere embodiment that does not imply inventive activity with respect to the state of the art. (Art. 8.1 of LP11 / 86).
As for dependent claims 2-5 and 7 to 11, design alternatives that are widely known in the state of the art and therefore obvious to one skilled in the art are considered.
The technical object of claim 12 is a offshore wind platform comprising at least two float cylinders, a bracing structure, attached to the floats and a wind turbine tower.
Documents D01 and D03 disclose all the technical characteristics of claim 12 and therefore lack of novelty (Art. 6.1 of LP11 / 86).
Dependent claims 13 to 17 are considered design variations that are well known in the state of the art and therefore, are not considered to involve inventive activity.
Document D03 discloses a offshore wind platform that has a system that allows it to be permanently oriented to the direction of the wind that has a buoy with anchoring means to the seabed, rotating electrical connection means and rotating means of mooring to the platform.
It is considered that one skilled in the art would attempt to combine the main parts of document D03 with document D01 of the nearest state of the art to obtain the characteristics of claims 18-23 and have a reasonable expectation of success. Therefore, the aforementioned claims are not considered to have inventive activity based on what is disclosed in documents D01 and D03 (Art. 8.1 of LP11 / 86).
