  • this method presents a method for the installation of the system that allows its uninstallation, repair and subsequent new installation.
  • This report describes a marine system for the production of electrical energy and installation method, which is of special application for installation at sea, taking advantage of the energy provided by wind and / or waves, being integrated into a single structure floating type "spar" buoy.
  • Floating systems are known that incorporate a wind turbine in its upper part, as well as systems of energy use of the waves.
  • JP2002303454 describes a large floating structure in which many systems are integrated, in order to produce hydrogen and oxygen, through various technologies, including wind and wave energy .
  • the floating spa “spar” system refers to systems that maintain the center of gravity below the center of flotation, thus achieving the desired stability.
  • the basic parts of a “spar” system include:
  • a lower ballast tank (“soft tank”).
  • the upper structure usually consists of a multi-level configuration of roofs in order to achieve a sufficient work area, while minimizing cantilever surfaces.
  • the upper ballast tank is responsible for providing sufficient buoyancy reserve to support the weight of the other elements, since none of them would have positive buoyancy by itself.
  • the term "hard tank” comes from the fact that its compartments are sized to withstand all the hydrostatic pressure without flooding them. It is usually divided into 5 or 6 levels of watertight compartments separated by roofs and each of these is further subdivided into another 4 by radial bulkheads.
  • the tank located at the height of the flotation usually has a double hull or double bulkheads ("cofferdams") to minimize the flood volume in case of collision with another vessel. In any case, it is usual that only the lowest level of tanks is flooded with a variable amount of ballast depending on the loading condition of the platform, leaving the rest empty.
  • the intermediate section extends from the lower base of the "hard tank” to provide the design draft to the structure.
  • the ladders of this central body are sized from the bending moments to resist during the phase of adrizamiento after the trailer to the point of final location. In a subsequent evolution, this central body was replaced by a less heavy lattice structure and a simpler and cheaper construction.
  • the TLP (Leg Platform Tension) is vertically attached, by means of tensions attached to the sea floor, in this way it avoids the ascending movement (“heave”) and the rotations of the axes contained in the plane of the marine surface (“piten and roll” )
  • the semi-submersible is a floating structure with a large roof, from which several columns that connect underwater with horizontal floating elements (called pontoons) come out.
  • a marine electric power production system is described, being based on a floating structure type "spar” that keeps the center of gravity below the center of flotation, so that the marine electric power production system It includes a floating structure type "spar” in which it is integrated:

  • synergies are obtained, both in the construction and in the use of the different components of the devices integrated in it.
  • the device for producing electricity through wind is defined by a wind turbine.
  • the device for producing electricity through waves is defined by vertical generators, which can be linear electric generators, air compression devices that have a coupled electric generator or seawater or fluid compression devices that have a generator coupled to a turbine as the final device.
  • the vertical generators are mounted between two platforms, being able to be linear electric generators or compressors of air, sea water, or other fluid, at the water level, constituted by cylindrical elements and their corresponding float movable along it by the wave action, generating electricity if it is an electric generator or compressing the corresponding fluid if it is a compressor.

  • the system incorporates a power electronics
  • controllers necessary for the adaptation of the generated electrical signals, according to the final application of the generated energy.

  • the system is capable of incorporating a hydrogen production device by means of water electrolysis, so that with the electric power produced, and by means of the electronics of adequate power and an electrolysing device, pure hydrogen will be obtained for various uses.
  • the pure water that the electrolyzer needs to produce hydrogen can be obtained by incorporating a Seawater desalination device, also integrated in the system itself.
  • the system can incorporate photovoltaic panels, allowing it to be autonomous.
  • This method also describes an installation method, which also allows and facilitates system maintenance.
  • the installation method is based on the construction of the complete port system, the subsequent floating drag of the assembly to the chosen site and the final fastening to the seabed, by means of chains or other anchorage devices.
  • the proposed installation method facilitates maintenance and is based on the idea that, in case of serious breakdown, the anchoring devices are released, the system is dragged to the port and the repair work is carried out, then it is taken again to the location and is reattached with the anchoring system.
  • the anchoring device that incorporates the system can be of different types, and, thus, it can be: catenary lines, "taut moorings", “tension / torsion leg” or other type of anchoring device.

  • the upper platform 8 must be at a certain height of the surface of the water 10 to never be impacted by the waves, due to the large load that they would have to bear in such case.
  • the system will have funding means 11 for positioning, in order not to undergo significant changes in the location of the system.
  • a device 12 for energy use of the currents can be integrated such that 2 devices are arranged symmetrically placed with respect to the floating structure, and arranged under the water level 10, as well as photovoltaic panels 13 that generate electricity for the system's own consumption, as can be seen in Figure 13.
  • a fish farm 14 is installed next to the energy production system 3 by waves, which allows to add value to the installation, both economic and ecological.
  • a hydrogen production system can be added by electrolysis, as seen in Figure 15 of the designs, so that with the electricity produced, and by means of the electronics of adequate power and an electrolyzer device, pure hydrogen is obtained for various uses Pure water, which electrolyser 16 needs to produce hydrogen, can be obtained by means of a desalination device 17 (desalination plant) of seawater integrated into the entire global system.
  • an installation method is also described, whereby the maintenance of the system in question is facilitated.
  • the installation method is based on the construction of the complete port system, the subsequent floating drag of the assembly to the chosen site and the final fastening to the seabed, by means of chains 11 or other means of anchorage.
  • Catenary lines They are the oldest and most common funding systems. Its restoration strength is based mainly on its weight.
  • Tension / torsion leg The flotation of the platform exceeds its weight, and this type of line counteracts the net force in a vertical and upward direction, holding the platform.
  • These types of lines are typical of TLP platforms, although they could also be used for other platforms, and one of these lines could even be used to hold a platform.
  • the catenary lines can use passive devices, such as dead weights, or floats, along their lines, in order to improve the dynamics of the floating structure or behavior structural of the line.
  • the “DP” (“Dynamic Positioning”) systems are active devices to control the position of the structure. They are based on an active system, such as propellers, or any other system that allows displacement, they are also controlled by a control device.

Abstract

L'invention concerne un système marin de production d'énergie électrique, fondé sur une structure flottante du type bouée 'spar' qui maintient le centre de gravité en-dessous du centre de flottaison. Ce système marin de production d'énergie électrique comprend une structure flottante (1) du type 'spar' constituée: d'un dispositif (2) de production d'énergie électrique au moyen du vent, et/ou; d'un dispositif (3) de production d'énergie électrique au moyen des vagues, et/ou; d'un dispositif (12) de production d'énergie électrique au moyen de courants marins. En ce qui concerne son procédé d'installation, une fois sa fabrication achevée au port, il est remorqué en flottaison jusqu'à l'emplacement choisi, et, finalement, fixé aux fonds marins avec des éléments (11) d'ancrage.
