The invention relates to the field of shipbuilding, and more specifically to means of generating electricity, and for the issue of providing electricity to consumers energy deficient regions.
Known offshore floating wind power plant (IPC F03D 11/04 priority from 08.03.2001, WO 02/073032 A1), which is a hollow semi-submersible column with connecting elements, one of which harshly or gently connected with single-point floating or fixed berth or mooring turret. The columns are reliance placed on them by wind power units (VEA), the number of which can be changed to increase the amount of generated electricity and arrangement which reduces the occurrence of the mutual influence of turbulent flows, these via prototype.
The specified structure has a number of disadvantages, which include:
- high cost due to the availability of berth or mooring turret;
- significant forces from currents and wave drift caused significant displacement of the submerged columns and connecting elements, and, accordingly, efforts anchor winches and lines:
- low initial stability, due to the cross-sectional area of the columns crossing the waterline;
large sediment that impedes the building, driving, and ek the operation of facilities;
- no possibility of using other types of renewable energy: waves, currents and the sun.
The task of the invention is to reduce cost through reduction of metal consumption, forces from currents and wave drift with the simultaneous increase in energy output and increase initial stability.
To do this, marine floating plants (MPAS), comprising a housing with a shape of a hollow isosceles triangle, the corners of which are the supports placed on their upper ends, WEA, cabin management and anchor the restraint system, the underwater parts of her body are through the cutouts, and the height of the freeboard is not less than 0.01 of the outer length of the boat. And landing WEA made in the form of masts and are located on the upper deck, the height of VEA on poles is not less than the sum of the length of their blades and maximum height of the waves from the respective area.
The length of the through cut of the underwater part of the hull exceeds 0.5 outer length of its sides, and their height is not less than 0.2 of its precipitation.
In addition, MPAS equipped to generate electricity by using the energy of waves, including wave floats and a hydraulic motor, an electric generator associated with the decrees of the data floats a high pressure pipeline. Moreover, the wave floats made and installed on Board with the possibility of rising above the tide water area.
However MPAS is set to generate electricity by using the energy of sea currents, including underwater generators, rotating under the action of currents and are located outside the range of the wave floats and anchor restraint system.
Along with this NAS equipped plant for electricity generation through the use of solar energy, including solar panels installed on the extra deck, located above the upper deck level above the highest wave heights corresponding area.
While wind and underwater generators, wave and solar installations equipped and connected by cables with the felling for processing and subsequent transmission to the onshore network cable, consisting of a surface, underwater and underground sections.
Execution in the underwater parts of the body through cuts designed to reduce the forces from currents and wave drift, and therefore the force anchoring restraint systems, and weight and body systems.
The size of the cut taken from the condition of providing buoyancy and stability MPAS, as well as the strength of the fixing support under VEA and underwater generators.
The heights of the freeboard on the quiet water accepted the conditions of safe operation of temporary staff, carrying out repair and replacement of equipment MPAS, as well as reduce the weight of the hull and applicati center of gravity (CG).
The implementation supports WAA in the form of masts and their placement on the upper deck MPAS allow, in comparison with columns in the prototype, significantly reduce their diameter, weight and cost.
Execution of the height of the poles is not less than the amount of maximum wave heights water area and length of the blade, via in which practically excluded the touch of waves blades of VAA during operation, reduces weight, cost and applicato CT masts, as well as to simplify the maintenance of WEA.
To limit the cost of production and repair of the wave floats in the water is only a necessary minimum of parts, and in the wheelhouse - hydraulic motor, an electric generator and computer control of the wave floats. To avoid damage to the floats by the intense excitement provided them rise above the waves.
Wind and wave setup can operate both simultaneously and separately.
Underwater generators that use the energy of sea currents, are located under the body on the depth component not less than the sum of the length of their blades and greatest provisory waves from the respective area.
The invention is illustrated by drawings, where figure 1 shows a schematic representation of the proposed marine p is Avoca power plant (top view without extra deck), figure 2 - front view and figure 3 is a view along arrow a (see figure 1) on the wave float.
On the upper deck of the housing 1 marine floating power available mast 2 with wind power unit 3 (figure 2)installed so that the turbulence caused by these units do not collide with each other. These aggregates have a diameter of obitaniya 4 (figure 2) and the surface area of the cable 5 for the transmission of electricity in the cabin management 6.
The housing 1 is connected with the anchor restraint system having an anchor line 8 with anchors increased holding power 9, and through the sleeve 10 and 11 underwater and underground sections 12 of the cable to the onshore electricity grid (figure 2). The housing 1 has through openings 13 (figure 2, 3) of length lbexceeding 0,5 outer length of its sides, and a height of dbconstituting not less than 0.2 of its precipitation, and freeboard F from the water line 14 (figure 2, 3).
The height of the mast 2 is selected so that the diameter of obitaniya 4 does not touch the greatest height of waves possible in the waters of the hwand the diameter of the mast is to ensure the perception of forces and moments from the wind and inertial loads caused by vibrations MPAS on the excitement.

The working body, mainly hydraulic oil 20 from each cylinder 18 has the opportunity to enter through the main pipe 7 (Fig 3) on the hydraulic motor 21 connected to the electric generator 22 (Fig 1), which is placed in the wheelhouse control 6. Wave floats 15 are made and installed with the possibility of rising above the waves. To rise above the waves at the desired angle α with vigorous agitation provided by the brackets 17 by hinges 19 (figure 3).
In addition, MPAS facilities to generate electricity by using the energy of sea currents, in which the underwater generator 23 with a diameter of obitaniya 24 of the blades 26 are located on brackets 25 under the housing 1 so as not to interfere with the wave floats 15 and anchor lines 8, and the length of the brackets 25 is not less than the amount of half of the maximum height of the waves possible in the waters, and the length of the blade 26. The brackets 25 cables 27 to the cockpit control 6.

At low wind starts rotating blades of VEA 3 masts 2 and the produced energy is transmitted through the cable 5 to the cockpit control 6, containing the necessary equipment (not shown) located on the upper deck of the housing 1. When reaching the maximum wind speed of WAA stopped to avoid damage to the blades, gearboxes and generators (not shown). Position MPAS in survival mode at the predetermined operation is ensured by the interaction of the anchor lines 8 and anchors high holding power 9. The reduction of forces from currents and wave drift, determining the load on the anchor line and anchor, is ensured thanks to the underwater part of the hull 1 of the cutouts 13 of the required (specified) sizes.
The strength of the blades of WAA provided by the fact that their diameter obitaniya 4 does not deal with the wave of greatest height possible in the waters.
At low agitation begin to move the wave floats 15, mounted on the AOC is the matte 17. Due to the movement of the floats 15 of the hydraulic cylinder 18 pushes the working fluid (hydraulic oil) 20 through a pipeline 16, located on the bracket 17, the pipeline 7, which delivers it to the pump 21, the torque of the electric generator 22 (figure 1 shows the relative), placed in the wheelhouse control 6.
When increasing the intensity of the excitement over the set, to avoid damage to the floats 15, pipeline 16 and cylinder 18, turn hinges 19 and raise to the desired height angle (angle α) of the specified equipment.
Underwater generator 23 with a diameter of obitaniya 24, mounted under body 1 on the brackets 25, start to work at a sufficient flow rate. Electricity generated through cables 27 is transmitted to the cutting control 6.
Electricity is generated by solar panels 29 located on the deck 28 mounted over the housing 1 on the stanchions 30, the cables 31 is transmitted to the cutting control 6.
After processing in the wheelhouse control 6 electricity from wind and underwater generators, wave and solar plants is transferred to coastal network through the coupling 10 and 11 underwater and underground 12 sections of cable.
Testing a model of the proposed plant on the excitement showed that the amplitude and acceleration of different types of pitching substantially the lower than vessels and floating platforms similar displacement and sizes.
Performed feasibility analysis confirmed the possibility of providing the cost of electricity lower than rates in some regions of Russia, as well as obtain an acceptable investment performance during the construction of the proposed power plant.
The proposed solution allows to reduce the cost of offshore floating power plant by reducing the weight of structures and restraint systems with a simultaneous increase in the volume of electricity generated and increasing the safety of operation due to the higher initial stability, which distinguishes it from the prototype.
