Definitions
- the present invention relates to an installation for producing offshore electrical energy from the thermal energy of the seas.
- the invention relates to such an installation which comprises a floating platform on which are embarked means for producing electrical energy from the difference in temperature of the water surface and depth, this platform shape being further associated with means for drawing water suction in depth.
- ETM Thermal Energy of the Seas
- the water may for example be at a surface temperature of 25 ° and a temperature of 5 ° C to 1000 meters deep.
- the cold water must then be pumped in very great depth through suction line means associated with the platform, while the hot water is pumped to the surface.
- the object of the invention is therefore to improve this type of installation.
- the subject of the invention is an offshore installation for producing electrical energy from the thermal energy of the seas, of the type comprising a floating platform on which electrical energy generation means are loaded. from the difference in temperature of the water at the surface and at depth and associated with means forming a deep water suction pipe, characterized in that the means forming a deep water suction pipe comprise three parts , a first formed of a rigid pipe whose lower end is immersed in great depth and whose upper end is immersed between two waters at reduced depth, a second portion formed of flexible pipes connecting the upper end of this rigid suction pipe to a third part of the suction pipe means, formed of rigid pumping pipes structuring a trellis it is of pipes fixed under the platform, in that the trellis further comprises rigid water discharge pipes at the outlet of the means for producing electrical energy and in that the rigid water discharge pipes are disposed at the periphery of the rigid pumping pipes in the trellis.
- the offshore installation for producing electrical energy comprises one or more of the following characteristics:
- the mesh comprises an intermediate float
- the intermediate float is provided with means for fixing means for anchoring the platform, and
- the upper end of the rigid suction pipe comprises a connection manifold for the flexible pipes.
- FIG. 1 represents a side view illustrating the general structure of a production installation according to the invention.
- FIG. 2 shows a perspective view illustrating the structure of a lattice forming part of an installation according to the invention.
- This hot water and cold water then make it possible to operate the means for producing electrical energy from the difference in temperature of these waters.
- the floating platform forming part of the production plant according to the invention is associated with means forming a deep water suction pipe.
- These means are designated by the general reference 2 in this figure and comprise in fact three parts designated respectively by the general references 3, 4 and 5 in this figure 1.
- the first part designated by the general reference 3 is formed of a rigid pipe designated by the general reference 6, whose lower end is immersed in great depth for example between 600 and 1200 meters deep and whose upper end is submerged between two waters at reduced depth for example a few meters or several tens of meters, as illustrated.
- This upper end of this rigid pipe 6 is then associated with buoy means or support float designated by the general reference 7 in this figure to maintain this rigid pipe 6 in position.
- Collector means designated by the general reference 8 make it possible to connect the upper end of this rigid pipe 6 to the second part 4 of the suction pipe means.
- This second part 4 of the suction line means is in fact formed of flexible pipes, one of which is for example designated by the general reference 9 for connecting the rigid pipe 6 to the third part 5 of the suction pipe means.
- This third part of the suction line means is in fact made of a mechanically welded mesh of rigid pipes.
- the collector 8 can be connected to three flexible lines themselves connected to three rigid pumping lines fixed under the platform and one of which is designated by the general reference 10.
- this trellis may also comprise rigid water discharge pipes at the outlet of the electrical energy production means such as for example the pipe designated by the general reference January 1.
- the trellis comprises six rigid water rejection pipes arranged in a circle around or at the periphery of the three suction lines as can be seen more clearly in FIG. 2.
- the mesh may be equipped with an intermediate float such as that designated by the general reference 12 in these figures, this float also being equipped, for example, with means for attaching anchoring the platform to hold it in position.
- the mesh is then formed of rigid pipes assembled and fixed for example to each other by means of reinforcing beams to maintain the integrity of this lattice under the platform.
- the means in the form of buoy or float 7 associated with the rigid suction pipe may have any suitable structure equipped with ballasting means to ensure the position holding function of this pipe.
- the outer surface of the rigid suction pipe may comprise at least one outer rib helix called "anti-vortex" designated by the general reference 13 in this Figure 1, in a conventional manner.
