Definitions

  • the present invention relates generally to an installation for the exploitation and extraction of large quantities of ores, for example polymetallic nodules present on the seabed.
  • Installations are also known which use devices capable of moving on the seabed and equipped with means for collecting and storing nodules. These machines can be towed by a cable from the surface or be self-propelled and programmed beforehand to operate on the seabed. Some of them having their own source of energy can also be produced so as to ensure not only the removal of the nodules but also their ascent to the surface.
  • the present invention relates precisely to an installation for extracting ores from the seabed at a great depth, which notably makes it possible to significantly improve the operating yield of a deposit and to provide the flexibility of use necessary depending on operating conditions.
  • the intermediate submarine station submerged at a certain depth below the water level so as to be constantly sheltered from swell includes autonomous means for keeping the relay unit and the vehicles in operation and to ensure the recovery and storage of the ore in the event of disconnection of the link with the surface vessel.
  • the installation for mining and collecting ore on the seabed at a great depth shown in Figure 1, consists of a ship 1 floating on the surface of the water, and several vehicles 50 for collecting ore, moving on the seabed 2 for example at 5500 meters below sea level.
  • the link between ship 1 and vehicles 50, for the supply of energy and the raising of the ore is performed as follows. First of all the ship 1 is connected by a flexible pipe 3 to an underwater station 20 submerged at a depth of the order of 300 to 350 meters, which itself supports by a rigid pipe 4 a relay block 30 submerged at a depth of about 4,500 to 5,000 meters.
  • Each vehicle 50 is connected to the relay block 30 by a set of cables and pipes 5 ensuring on the one hand the transmission of energy and the control of the commands and on the other hand the ascent of the ore to the relay block 30.
  • These cables and pipes 5 are held by floats 6 so as not to transmit parasitic forces to vehicles 50.
  • the vessel 1 constituting the base of life supplies the energy to the various motors and pumps necessary for the operation of the entire installation and ensures the storage of the ore collected between two rotations of the ore carriers.
  • the intermediate submarine station 20 shown in more detail in Figures 2 and 3, is located about 300-350 meters below the water level, in order to be sheltered from the effects of the swell . It mainly comprises an apron 21 on which are mounted a connection box 22 between the flexible pipe 3 and the rigid pipe 4, and several primary pumps 23 capable of pumping the mixture of ores and seawater from the relay block 30 by line 4 and driving this mixture to the surface ship 1 via line 3.
  • a longitudinal float 24 is mounted on each side of the deck 21 to maintain the station at altitude; these floats can possibly serve as buffer storage of the ore, for an operation of about ten hours, or for example 3000 m 3 per float, in particular in the event of disconnection of the link with the ship, as will be seen later.
  • each float is connected by a pipe 25 to the connection box, Z ment 22.
  • This underwater station 20 also includes a system of longitudinal and vertical thrusters 26 for maintaining it in heading and altitude, as well as a control system 27 receiving orders from the ship and control of the pumps 23 and thrusters 26.
  • L electricity necessary for the operation of the station is supplied by ship 1, but in the event of disconnection of the link with said ship, one or more standby generator sets 28 mounted on the bulkhead 21 supply the electricity necessary.
  • the relay block 30 located at 4500-5000 meters below the water level, is attached to the underwater station 20 via the ascent pipe 4 and cables not shown. It mainly includes everything that is not essential on 50 vehicles in order to limit the energy to be brought to the bare minimum.
  • This relay block ( Figures 4 and 5) includes a platform 31 supporting a silo 32 to allow among other things a buffer storage of approximately 500 tonnes of ore between the vehicles 50 and the station 20.
  • On this platform are also mounted hydraulic groups 33 with sea water and a monitoring and control system 34.
  • the hydraulic groups 33 supplying pressurized water to actuate the hydraulic motors of vehicles 50, are powered by electric motors 35 receiving the energy of the ship through the submarine station 20.
  • the control system 34 is capable on the one hand, of carrying out a certain number of pre-programmed tasks and, on the other hand, of carrying out the orders given from the ship according to the elements transmitted to the latter.
  • the silo 32 has multiple tangential entrances 36 at its upper part to form a vortex; these inlets each communicate via a pump 37 with a pipe 5 for the ascent of the ore into the silo from a vehicle 50. Each inlet 36 is therefore connected to a vehicle which allows the ascent of the ore to from several vehicles simultaneously.
  • a grid 38 in the shape of a cone directed downwards, so as to effect the sorting and final washing of the ore by gravity.
  • the upper pipe 4 for raising the ore to the ship by the station 20 enters the interior of the silo 32 and emerges above the grid 38.
  • said block relay comprises propellants 39 as well as vertical stabilizers 40 arranged on each side of the silo 32.
  • the collection of the underwater ore is carried out by the vehicles 50 (FIGS. 6, 7 and 8) which mainly consist of a carrying chassis, a propulsion system, a ore collection, and an ore washing and processing system.
  • the chassis 51 consisting of metal beams 52 internally lined with foam supports the various elements of the vehicle and in particular the propulsion system 53.
  • This propulsion system 53 is formed by example by a pair of tracks 54 and 55 located on each side of the chassis 51.
  • Each track (54-55) is driven by wheels 56 which are themselves driven by hydraulic motors 57 housed in the rim.
  • the pressurized water for the hydraulic motors 57 is supplied by the hydraulic groups 33 of the relay block 30.
  • Each wheel 56 is driven by a hydraulic motor 57 so as to ensure high mobility of the vehicle.
  • the tracks (54, 55) in mixed metallic and composite structure, are provided with notches internally for the connection with the wheels 56 and externally to ensure a grip on the ground.
  • the ore collection system which consists of two trains of bucket chains 58 arranged in line so as to cover a sufficient width.
  • Each train of bucket chains 58 is independent and can pivot around an axis 59 located at the top. This pivoting is controlled by a jack 60 and makes it possible to adapt each train to the configuration of the ground.
  • the endless chains 61, support of the buckets, pass on wheels 62 mounted on arms (63-64), connected to one another in an elastic manner, for example by springs 65, so that when a bucket hits an obstacle (large stone, rock), the lower arm 64 is raised and the bucket passes over the obstacle instead of bracing on it.
  • the buckets are also protected by bumpers 66.
  • the buckets pour their collection into a treatment and washing system comprising two conveyor belts (67-68) superimposed and made up of a mesh with calibrated mesh for the selection of nodules.
  • the excessively large nodules as well as the sediments are evacuated in a hopper 69.
  • a first washing is. provided by ramps 70 located above the carpet 67.
  • the nodules thus selected are then transported in a tank 71, using a screw 72 in which they are rid of the gangue which may remain and where they undergo a second wash.
  • the tank 71 is connected to the pipe 5 for raising the nodules to the relay block 30.
  • Each vehicle 50 is of course equipped with an underwater observation device, a detection device or an acoustic display system, in order to ensure safe and easy operating conditions, even in the case where the water is cloudy and where visibility is reduced.
  • the ore pickup facility operates as follows.
  • the assembly - submarine station 20 and relay block 30 connected to said station by line 4 is maintained, thanks to the thrusters 26 and possibly ballasts, in a position such that station 20 is located approximately 300-350 meters below the water level.
  • This assembly can also evolve according to the orders given from the ship 1.
  • the personnel on the ship controls the operation of the installation and can intervene at any time.
  • the energy necessary for the operation of the installation and in particular of the various elements of the vehicles 50 is supplied by the ship 1 and the pressurized water for the propulsion of the said vehicles is supplied by the hydraulic groups 33 of the relay block 30
  • the vehicles 50 therefore move on the bottom 2 and pick up the ore.
  • the two trains of bucket chains 58 pour their collection onto the upper belt 67 where a first washing is carried out by the ramps 70.
  • This belt 67 lets nodules of a given maximum caliber pass as well as the sediments and retains the excessively large nodules, which are evacuated by the hopper 69.
  • the second conveyor belt 68 located below the first, collects the accepted nodules and lets pass the sediments which are also rejected towards the evacuation hopper 69. Then the nodules transported by the screw 72 are rid of the gangue and undergo a second washing, before falling into the tank 71.
  • the mixture of ores and seawater collected in the tank of each vehicle is reassembled under the effect of the pumps 37 to the relay block 30.
  • the arrangement of the tangential inputs 36 in the silo 32 is such that the nodules undergo, under the effect of the whirlpool thus created, an additional and natural cleaning without energy supply. They also undergo a new sorting through the grid 38 and are temporarily stored inside the silo 32.
  • the primary pumps 23 of the station 20 suck in via the ascent pipe 4, the mixture of ores and seawater from the relay block 30 and pump this mixture through the loading pipe 3 to the surface ship.
  • an intermediate submarine station 20 between the relay block 30 and the ship 1 has many advantages. This station is maintained at a depth of about 300 to 350 meters below the water level, in order to be constantly sheltered from the effects of swell. In in the event of a storm or rough sea, it is sufficient to disconnect the vessel 1 from the loading line 3 which is marked on the surface by a buoy 10 (FIG. 1). The entire subsea installation can remain in place and be held in position by the various thrusters which are supplied with energy by the generator sets 28 placed on the station 20. The position of this assembly is constantly monitored by the monitoring and control system 27 also arranged on station 20.
  • the generator sets 28 supply the energy necessary to supply on the one hand the primary pumps 23 in order to raise the ore mixture which is in the pipe 4 and the silo 32 of the relay block 30 and on the other hand the pumps 37 of said relay block and the pickup vehicles so that the ore collection continues.
  • the reassembled mixture is oriented via the connection box 22 and the pipes 25 to the floats 24 of the station 20 (FIG. 2) to be stored there, which allows the installation to operate for another a few hours after disconnection with the ship.
  • the control system 27 cuts off the power to the pumps and the collection vehicles while waiting for the connection with the ship to be made again.
  • This arrangement therefore makes it possible to avoid dismantling the underwater installation in the event of bad weather and to maintain a sufficient yield for ore extraction.
