    It is a disk-shaped platform that floats on the water (seas or lakes), which supports a wind generator and whose dimensions allow to obtain angles of inclination, by the effect of wind and sea, admissible for the conditions that require each generator, taking advantage of the stability provided by the moment of inertia of the flotation. Its greater length in flotation with respect to those that are currently being used, results in a wave behavior that is much higher than the current one, which translates into a lower inclination with the same wave height. Its much lower weight with respect to those that have begun to be used for this purpose, reduce its price in a very considerable way. It is also multipurpose because they can be easily installed (because of its small height and its deck being very close to sea level), other generators of sea energy such as waves, currents and/or tides. By being able to install ballast tanks and mobile or fixed bows, it can adapt to an endless number of meteorological and limiting conditions that the wind turbine may be subjected to.

    IIULTIPROPOSITE FLOATING DISK PLATFORM FOR SUPPORT OF MARINE EóucoS GENERATORS AND OTHER GENERATORS OF THE
    MARINE ENERGY.
    SECTOR OF LATÉCNICA B Field of application is in the maritime sector and within this, in the field of marine renewable energy (offshore).
    LATÉCNICA STATE Marine renewable energies are being implemented in a general way. Of these, wind power has just over 2,500 MW (megawatts) installed, most of them, through platforms supported by the bottom of the sea (Jack up).
    As this technology has been spreading And those countries that do not have a continental platform are wanting to join in this way of obtaining energy (which may lead them to be energy independent from other countries), they need to move on to install wind turbines on floating platforms.
    Platforms supported by the bottom of the sea do not suffer any indination from wind and waves. However, the floating ones do. Hence, the floating ptataphonnes must respond to the thrust that the wind exerts on the generator through the blades, which consists of a very small angle of indination and that varies with the generator's operating conditions. In calm waters, in which only the wind tilts the platform (not the waves), this angle is set at 1 °.
    The first floating platforms for wind generators (not yet multipurpose) are SPAR model and are under construction in Navantia -Fene for a tooth in the United Kingdom that will put them into service in Scottish waters.
    These are like a vertical cylinder, of small diameter and very high, very heavy, that balance the wind turbine by the counterweight and have an important anchoring system that keeps them linked to the sea floor.
    The models designed in the world for this type of floating support (for wind energy) are:
    SPAR, which receives its name from this type of buoys whose anchoring system is very studied, and that resemble the so-called "monopilars-which are installed on a platform supported by the seabed or Jack up. They consist of a cylindrical tube with floating vertical, with diameters between 9 and 15 m. and heights between 120 and 90 m. respectively. The weight of the structure is of the order of 2,250 Tm. Stability is achieved, above all, by the counterweight of the structure.
    SEMI-SUBMERSIBLE, consisting of three vertical cylindrical floats joined together forming a platform, but whose weight is more than double that of the previous one, and that has never been used, and
    BARGE, which is a floating PRISMATIC platform, of which no development is known on the technical information available in the world and which bases its stability on the inertia of the flotation rather than the counterweight.
    See Figure 1.
    On these Platforms it is installed: the Tone and the Gondola that is rotating and includes the core that is where the generator is located and that is driven by the blades. Elements all foreign to this invention. EXPLANATION OF THE INVENTION,
    The industrial design that is intended to be registered is a · Multipurpose Floating Disc Platform · (PDFm) for the support of wind generators and other generators of sea energies such as waves, tides and sea currents, of the multipurpose BARGE type with floating polygonal multi-sided or circular and large diameter.
    Never four-sided prismatic as presented by the BARGE model in the previous section.
    See Figure 2.
    The Tower with its wind generator, nor the important anchoring system linked to the platform, are not the object of this invention, but the floating disk that supports the Tower and is connected to the anchoring system.
    We will refer hereinafter to the Platform as support for the Tower with its wind generator although, as has been said, the Platform is capable of housing generators to extract energy from waves, sea currents and / or tides, being the cover very close to the sea level and easily allow this type of facilities that would complement the wind energy and increase its profitability.
    It could only be used to support sea power generators but wasting it not installing wind power generator would not be logical.
    The base is a multi-sided polygonal flotation (the possibility of circular flotation will be implemented whenever its construction is more simple and economical) of large diameter that allows to present to the sea and the wind from different directions, an always positioned structure, while that the power generating propeller is oriented to the wind by the turn of the gondola that sustains it.
    It is a disk of dimensions such that its stability characteristics, caused by the moment of inertia of the flotation, allow to maintain minimum oscillations in the operating ranges, with a minimum weight and cost.
    Unlike current platforms, this innovation presents a platform such as a disc, low height, large diameter and low weight.
    For each thrust or power generated in the wind turbine and angle of inclination there will be dimensions that will meet these requirements. To finally refine or specify the characteristics and the anchoring system, a test of a model with dimensions proportional to the number of Fraud in a wave tank must be carried out.
    With the same solicitations (conditions of sea, wind and absorbed power) and performance (angle of inclination, period of balance) that the platforms that are being installed, the invention presented, would have the order of four times less weight than the current SPAR type brackets, according to the following table:
    Diameter (m) Height (m) Weight (Tm) SPAR 15 90.00 2,250 PDFm 50 1.30 600
    For different requests and benefits the dimensions would vary (as stated) but the PDFm would always maintain a substantial improvement over the SPAR.
    Therefore, its cost will also be much lower as it is almost proportional to the weight.
    By reducing the weight, the funding system is also reduced (a fundamental system for the work of these floating platforms), which is thus reduced in price, as this is also proportional to the weight.
    The diameter of the disk will vary depending on the thrust on the generator shaft for the same exterior conditions and the height or strut of the disk, from the maximum wave height to be supported when supplying power.
    The possibility of installing a counterweight under the platform is not considered because it worsens the stability conditions.
    The behavior of the PDFm with waves is far superior to SPAR.
    The frequency and height of the waves varies with the depth and intensity of the waves. It is known that floating structures (ships) whose length or length is equal to or greater than the wavelength of the waves do not have pitching movements, while smaller vessels (boats or boats) oscillate taking the inclination of the wave profile.
    In other words, a greater length or length of platform (in this case diameter) reduces the pitching movement.
    In case of bad weather the Platform could be sunk taking advantage of its ballast tanks and service pumps, remaining only on the surface of the sea, the T arre,
    PLATFORM EQUIPMENT This section describes the equipment and installations of existing devices, conveniently adapted to the Platform, without limitation, but which in one way or another must carry on board each platform to better fulfill the purposes of the invention :
    Structure of union of the Tarre to the platform,Ballast tanks, built into the structure to further reduce theswing or admit higher speed winds or higher waves.Electric pumps for ballast and shedding arranged in the center of thePlatform.
    · Proasft or structures that are placed forward to the direction of the sea in eachmoment through a system that could be electric or hydraulic whichwould lift or put in place some plates as a amura or bow. Thisform would avoid "wetting" the cover losing some inertia in the flotation andtherefore stability, which would increase the angle of inclination. Another optionit would be to increase the strut at the ends giving the shapes a certain"I ruin · but that would force the installation of scuppers or drains incover to expel water inlets by spraying.See figure 3.Power voltage transformer generated to commercial voltage foractivate installed equipment,Connections of the energy generated to the underwater network,Lighting,Alarm and control devices,Hydraulic or electrical power station,Electrical distribution board,Electric batteries,Cathodic protection equipment,Antioxidant and antifouling paint system on all surfaces,Accesses, scales,Waterproof doors and hatches,
    Security means,
    Rowing eyebolts and mooring elements TECHNICAL CHARACTERISTICS
    For a better understanding, the specific technical characteristics that a Multipurpose Floating Disc Platform would have to support and service a 5 PtItN wind turbine are detailed below, which is the size most used at the moment, so that the indination is 1 °.
    By proceeding in a similar way, the dimensions for 4 PtItN, 6 MN wind turbines, etc. can be specified.
    The production of this power of 5 MN or 5,000 kW (a house has installed a power of the order of 5 kW) needs to withstand winds of 40 kmIh and the corresponding swell, being the necessary and sufficient condition that the angle of indination is not higher at 1 ° in calm waters (without waves) in order that the performance and efforts in the generator are admissible. It is necessary to indicate here that this condition could be modified based on the characteristics of the generator and the Platform would modify its dimensions to adapt to those conditions.
    For more constructive ease, a twelve-sided polygonal platform has been chosen, which will have the following main dimensions:
    Radius: 25m Diameter: 50 m Height: 1.30 m. Weight: 600 tons. Draft: 0.45 m.
    This weight corresponds to a construction made with Naval Steel A and a radial structure, as explained below with the equipment indicated in the previous section and with six sea power generators.
    With these characteristics, the platform would float with a draft of 0.45 m.
    It is important to note that the distance, in height, not submerged is: 1.30 -0.45 = 0.85 m.
    5 0.85 m. it is, therefore, the buoyancy reserve or the margin that exists (with these dimensions chosen) to absorb the balance movements produced by the waves without the deck entering the water and therefore losing adrifying moment provided by the area of the flotation
    1 o This Platform would be mounted equipment that without limitation are listed in the previous section (joint structure, ballast tanks, etc ...)
    PREFERRED EMBODIMENT OF THE INVENTION
    15 20 Being in the marine environment and afloat (not supported by the seabed) its structure is very similar to that of a boat arranged to withstand the shear stresses in the center that transmits the weight and momentum of the Generator Tower by the thrust on this one of the blades driven by the wind and those of flexion that will take place by the flotation and the swell. The most suitable construction site, although not extrusive, would be a shipyard because of its proximity to the sea and its knowledge of the environment in which the structure will be, the sea.
    25 The materials can be as diverse as those of the boats and construction techniques similar to those of the boats, as indicated.
    30 The construction system will respond to the shipbuilding techniques guaranteed by the Regulations and Classification Societies for these floating devices.
    35 As an example and for the twelve-sided polygonal platform described above of 25 m. of radius and 1.30 m. height, proceed as follows: Material: Naval steel A collected in sheets, profiles and bulbs,
    Radial structure completely waterproof, Structure of union of the Tower to the Platform also of Naval A steel, with radial structure in continuity with the structure of the Platform and an outer plate of 20 mm. of thickness. Eleven equal MODULES and the number twelve equal but with two cockpits (vertical structure in the direction of the radius) would be manufactured instead of one as the rest, as indicated in Figure 3 consisting of: cockpit 10 mm thick; varengas or transverse reinforcements and longitudinal reinforcements at the end of the 6 mm module. thick, more tires with bulbs in the bottoms and cover, all enwelto by an outer lining of 8 mm thick.
    These modules would be built in a workshop, soldiers with procedures and construction details approved by a Classification Society (L1oyd Register, Bureau Sales or others) and with a careful preparation of surfaces to apply antioxidant and antifouling paint (it is in the submerged external part) . The twelve modules would be assembled in the yard of a shipyard by its surface and proximity to the sea placing them by cranes and construction bed in continuity, respecting the construction plane.
    Finally, the T-Orre-Platform joint structure would be installed by welding it to the top of the Platform.
    Finally, the tightness tests would be done and it would be thrown into the sea to be finally towed to its final location on the high seas.
    The assembly at sea will be very similar, but simpler, to the one currently being carried out on the current platforms. This being an important issue too, as it is an important part of the final cost.
    The ones supported at the bottom, anchored at the bottom, do not float and must be transported in very special and expensive boats.
    The floating SPAR type to have a lot of height and draft must be transported lying down and put them vertical in their final location by means of support boats also complicated and expensive.
    The floating, object of this invention (PDFm), when floating and having little draft, can simply be towed without any special maneuver in place.
    In the case of the PDFm, once located and attached to the anchoring system, the Tower would be installed on it, following the same techniques with the crane-ship, they are followed for those anchored at the bottom of the sea but having to save a much lower height. which will allow the use of less expensive support boats.

    We have to say that he has finally won the "BUOY SPAR".
    The other opponent has been for some time the · SEMISUMERGIBLE (0C4 CONCEPT) "but has finally been displaced by the SPAR, mainly for reasons of weight and therefore price.
