- control means 76 send an activation signal to the base station 26 and the vehicle 28 to electrically power the sampling means 34 and control the movement of the vehicle 28 on the bottom 14.
- the sampling means 34 take the material located on the bottom and bring it to the entrance of the light 37.
- the pumping means present on the base station 26 initiate the ascent of the material to the installation 18 consisting of a liquid / solid mixture.
- the compressor 74 is started.
- the compressor 74 then injects gas into the passage 48, for example compressed air at about 100 bar, into an injection point 142 situated between the first point 38 and the second point 40.
- This injection point 142 is for example located at a depth of about
- a continuous flow of sampled material is then established between the sampling means 34 and the separation chamber 114 through successively the light
- the mixture collected at the nozzle 118 consists of liquid, solid and gas flowing at a suitable speed preferably between 15 and 20 m per second.
- the outlet valve 132 of the separator 72 is kept closed, so that the pressure in the separation chamber 114 is greater than the atmospheric pressure.
- This pressure is for example between 15 and 30 bar.
- the liquid / solid / gas mixture then enters the chamber 114 where it undergoes separation by gravity.
- the gas collected in the upper part of the chamber 114 is reinjected into the compressor 74 through the outlet 123, which limits the pressure drop and the size of the compressor 74.
- the solid material accumulates in the bottom of the chamber 114 around the worm 130.
- the valve 132 is opened and the worm 130 is activated to evacuate the solid material and a part of the liquid, through the intermediate pipe 128 to the retention tank 102.
- pressurized water is injected through the inlet 124.
- the bottom assembly 22 is mounted to the surface by winding the conduit 24 around the drum 68 as previously described.
- the flexible conduit 24 does not have an electric power transfer line.
- An umbilical with power lines that is lowered simultaneously during the descent of the flexible conduit 24 to provide power to the excavating vehicle 28.
- the separation chamber is not maintained under pressure when unloading the material therein.
- the size of the compressor 74 is greater and the injection point is lower than in the first device 10 according to the invention.
- the bottom assembly does not have a base station 26.
- the flexible link 30 is connected directly to the flexible conduit 24 via an adapter nozzle.
- a second device 210 according to the invention is partially shown in FIG. 8. Unlike the first device 10, the second device 210 comprises, in the deployed configuration of the flexible conduit 24, a plurality of injection units 212. a pressurized liquid in the circulation passage 48, for conveying the material to the surface installation 18.
- Each injection unit 212 is for example mounted between two fixing flanges 54A, 54B of two adjacent sections 50 during the deployment of the flexible duct 24 out of the drum 68.
- the units 212 are for example mounted by operators placed on the mounting station 63 and these units 212 are held on the flanges 54A, 54B by respective fixing clamps 213.
- Each pumping unit 212 thus comprises a sleeve 214 internally defining a portion of the flow passage 48, a nozzle 216 for taking water from the body of water 12, and a distribution in the passage 48, and a hydraulic turbine 218 for pumping and pressurizing the injected water.
- the nozzle 216 defines a generally transverse lumen 230 which opens outwardly into the body of water 12 through a strainer 222, and inclined axially upwards in the passage 48.
- the hydraulic turbine 218 is fixed on the sleeve 214.
- the turbine 218 is fed hydraulically through a tapping 224 on a functional line 44A coming from the installation 18.
- the tapping 224 opens into the water body 12 by an evacuation 226 after passing through the turbine 218, without being connected to a lower part of the line 44A located in the section 50 under the sleeve 214.
- the sleeve 214 further delimits at least one section 228 of another functional line 44B intended to feed another pumping unit located under the unit 212.
- the turbine 218 is supplied with hydraulic fluid from the surface installation 18 via the line 44A and the tapping 224.
- the feed of the turbine 118 causes water to be drawn into the lumen 230 through the strainer 222, then the pressurization of the water sucked into the light 230.
- the pressurized water thus obtained is injected into the passage 48 to drive the material flowing in this passage 48 to the surface installation 18.
- the presence of units injection nozzle 212 distributed along the flexible conduit 24 allows to remove the pump on the base station 26 and the injection of transport gas in the passage 48. This particularly simplifies the installation of surface 18 which is free of compressor.
- the turbines 218 are powered electrically by a functional line placed in the flexible conduit or by an outer umbilical.
- the third device 250 shown in Figures 9 and 10 differs from the second device 210 in that the injection units 212 are devoid of hydraulic turbines.
- the pressurized liquid to be injected into the circulation passage 48 is stored in a pressurized reservoir disposed on the vessel 20 in the surface plant 18.
- Each unit 212 comprises an annular distributor 252 of liquid under pressure disposed around the sleeve 214.
- the annular distributor 252 delimits a peripheral cavity 254, of toric shape around the axis of the duct 24.
- the cavity 254 is connected to the surface pressure liquid reservoir via the functional line 44A. It is connected to the passage 48 by four radial injection orifices 256 distributed angularly around the axis of the duct 24, as illustrated by FIG. 10.
- Each injection orifice 256 opens axially upwards into the passage 48.
- the pressurized water is fed into the cavity 254 of the distributor 252 from the reservoir of the surface installation 18, through the functional line 44A. . It is distributed uniformly in the cavity 254 to be injected through each orifice 256. More generally, such pumping units could be used on a flexible conduit of any installation.
- sampling means 34 comprise an excavation crane 312, deployable and operable from the surface installation 18 independently of the flexible conduit 24.
- the bottom assembly 22 further comprises means 314 for receiving and treating the material, placed on the bottom 14 of the body of water 16 while being connected to the flexible conduit 24.
- the crane 312 comprises a gripper 316 for sampling material on the bottom 14, and a cable 318 for deploying the clamp 316, to descend the clamp 316 from the vessel 20 to the bottom 14.
- the receiving means 314 comprise an adjustable support support 320 placed on the bottom 14 and a crusher / crusher 322 mounted in the support 320.
- the support 320 defines a funnel 324 for receiving the material taken by the clamp 316 open upwards. and opening towards the mill / crusher 322.
- the support 320 is deployable from the surface installation 18 to the bottom 14, by deployment means (not shown) independent of the crane 312.
- the support 320 has adjustable feet to maintain it substantially horizontally and fix on the bottom 14.
- the support 320 and the crusher / crusher 322 are connected to a free end of the flexible link 30, to connect the hose 36 to the crusher / crusher 322.
- the receiving means 314 and the flexible conduit 24 are lowered towards the bottom 14, until the support 320 is placed on the bottom 14 while being immobilized on the bottom 14.
- the crane 312 is then manceuvrée to bring the gripper 316 in contact with the bottom 14.
- the gripper 316 is then activated to take material on the bottom 14, then is moved next to the funnel 324 to deposit the material taken by the clamp 316 in the crusher / crusher 322.
- the material processed in the crusher / crusher 322 is then reassembled at the surface installation 18 through the hose 36 and the flexible conduit 24, as previously described.
