For the purpose of insuring a constant speed of the hydraulic turbine, a suitable speed regulator or governor 46, which can be of any known type, is disposed in the intake line 14 near the hydraulic turbine, and is appropriately operated from the turbine shaft 17. This speed regulator will vary the rate of flow of water reaching the turbine inlet 15, to compensate for variations in load imposed on the hydraulic turbine and for variations in the hydrostatic head of fluid in the reservoir 12 and in the intake line 14. By way of example, the speed responsive regulator or governor can be of the type illustrated on page 1303 of Marks Mechanical Engineers Handbook, fifth edition. This reservoir is carried from the floating vessel or barge by a suitable supporting structure 13, the water in the reservoir passing therefrom through an intake line 14 to the hydraulic turbine inlet 15 and then discharging from the turbine through an exhaust line 16, from which the water returns to the ocean W. The hydrostatic head of water rotates the turbine 11, its shaft 17 rotating a suitable load source connected thereto, such as an electric generator 18, which supplies electrical energy to the electric motors, and other power consumers (not shown), on the floating vessel.
A control device may be used to maintain the speed of the turbine constant, despite changes in the load or variations in the hydrostatic head of liquid supplied by the reservoir to the turbine. The system illustrated can also be used in connection with a drilling platform 10 fixed to the floor of the ocean through use of supporting legs (not shown), the cylinder 20, reservoir 12, hydraulic turbine 11 and electric generator 18, and all of the equipment associated therewith, being supported by or on the platform.

Such water is employed for rotating a hydraulic turbine connected to a suitable load, such as an electric generator, for the purpose of generating power at no expenditure of fuel. In fact, in lieu of a single set of a cylinder, piston and piston rod being associated with the captive float, a plurality of cylinders, pistons and piston rods can be employed, which will greatly increase the volume of water pumped through the discharge line or lines 37 to the reservoir 12, which is supported at a substantial height above the level of the hydraulic turbine 11, which, as has been stated above, is preferably mounted on the floating vessel adjacent to the surface S of the water.
In the operation of the system disclosed, the floating vessel or platform 10 will move up and down relative to the captive or stationary float 24 and the piston rod 22 and piston 21 several times a minute under the action of the ocean waves. The power requirements of the equipment mounted on such floating vessels and platforms are comparatively large and require the consumption of large quantities of fuel, which must not only be stored on the vessel or platform, but also transported thereto, all of which is costly.
The rod is affixed to a submerged captive float 24 of comparatively large mass having comparatively great buoyancy. The vessel or barge floats in a body of water W, such as an ocean, the well bore (not shown) being drilled in the underlying formation F. The drilling equipment is not disclosed since it forms no portion of the present invention, which is directed to the generation of electric or other power used for operating the drilling and other equipment located on the floating vessel 10. Such vessels are often of comparatively large size, weighing thousands of tons, and move vertically several feet under the action of waves, which, typically, may average about four to five feet. Since drilling vessels or barges often weigh thousands of tons, water at large volumetric rates can be pumped to substantial heights as a result of vertical motion of the vessel or barge incident to the action of the ocean waves, thereby insuring the presence of sufiicient water in the reservoir at all times for the continued generation of electric power in relatively large amounts.

In general, the invention is directed to a power generating system in which the energy of a vertically moving vessel, such as a drilling vessel, or of a large float used in conjunction with a fixed offshore drilling platform, is employed to pump water to a reservoir of adequate capacity located at a suitable height above the water surface, the water flowing from the reservoir downwardly to and through a suitable hydraulic turbine coupled to an electric generator, or other energy consuming equipment. The form of invention illustrated in the drawings includes a floating vessel, barge, or platform that can be of any suitable type used in the drilling of oil, gas, or sulphur wells at subsea locations. A one-way inlet valve 32 is disposed in both the upper and lower branches 33, 34 of the suction line 29 to permit water to flow upwardly through the line and into the cylinder, but to preclude return or reverse flow of water from the cylinder through the line.29.

The water from both the head end and the rod end of the cylinder is forced through the upper and lower branches 35, 36 of a pump discharge line 37 that extends upwardly to the reservoir 12. Thus, the liquid in the head end of the cylinder passes through a one-way discharge valve 38 in the upper branch into the pump discharge line 37, and from the lower end 31 of the cylinder through a one-way discharge valve 38 into the pump discharge line 37, the two valves permitting liquid to flow in only one direction therethrough; that is, they permit fluid toflow from the cylinder 20 into the discharge line 37, but prevent reverse flow of fluid back to the cylinder. Dolor muscular piernas . Thus, the coaxiality between the cylinder 20 and the floating vessel 10, on the one hand, and the piston 21 and piston rod 22., on the other hand, is maintained.

The floating vessel is appropriately anchored at the location so that its drilling equipment is properly located over the well bore, and will remain in such location. The float will move up and down under the action of the waves and shaft the piston rod 22 and piston 21 with it in the cylinder 20, the float being guided in its vertical movement by suitable guides depending from the drilling platform, in essentially the same manner as the guides 27 depend from the floating vessel 10 in the present drawings.
5. In a wave-driven power generating system as defined in claim 1; wherein said pump comprises a cylinder secured to one of said members and a piston secured to the other of said members, whereby relative reciprocation between said cylinder and piston pumps water to said reservoir. This float is prevented from moving upwardly by being anchored at the ocean floor or mudline H, as by a plurality of anchor lines 25 secured at desired points to the float which are secured to the ocean floor, as by being attached to a suitable concrete block or mass 26 embedded in the ocean floor and rigidly secured to the formation F. The floating vessel 10 and the captive float 24 are maintained in appropirate relation with respect to one another by vertical guides 27 disposed on the four sides of the captive float, assuming it to be of rectangular horizontal section, the guides being secured to the floating vessel 10 and being engaged by roller devices 28 mounted on the captive float.

It is also of appropriate height to insure against engagement of the piston 21 by the head end 40 and the rod end 23 of the cylinder during the maximum stroke of the floating vessel or barge 10 relative to the captive float 24 and piston rod 22 and piston 21 secured thereto. The vertical reciprocations of the floating member or vessel 10 are employed for pumping water to the reservoir 12. As disclosed, a pump 19 includes a cylinder 20 suitably aifixed to the floating vessel 10, and movable upwardly and downwardly therewith relative to fixed or compratively stationary piston 21 contained therein and secured to a suitable piston rod 22 extending through the lower rod end 23 of the cylinder. It is, accordingly, apparent that a power generating system has been provided which utilizes the large amount of energy available in a large and heavy floating structure for pumping large quantities of water to a water storage reservoir, all under the action of the ocean waves.
7. In a wave-driven power generating system as defined in claim 1; and regulator means responsive to the speed of said hydraulic motor for controlling flow of water from said reservoir to said motor. 6. In a wave-driven power generating system as defined in claim 2; wherein said pump comprises a cylinder secured to said platform member and a piston secured to said float member, whereby reciprocation of said cylinder along said piston pumps water to said reservoir. Since the reservoir height above the pump 19 is not too great, the cylinder 20 can be made of a large diameter. Water from the ocean is drawn through a suction line 29 communicating with the upper or head end 30 of the cylinder and with the lower or rod end 31 of the cylinder.
This invention possesses many other advantages, and has other purposes which may be made more clearly apparent from a consideration of a form in which it may be embodied. The power generated by the system decreases that required from the prior sources of energy, considerably reducing the fuel requirements and consumption of such other sources.
