Definitions
- the present invention relates to a deep sea mining method comprising;
- EP2570340 generally relates to a device for capturing fluids lighter than water escaping from an underwater source.
- the device is useful for collecting and temporarily storing oil and/or gas escaping from an out-of-control deep-sea borehole.
- EP2570340 intends to provide an improved device for collecting and temporarily storing fluids rising from an underwater source, in particular with respect to the device's ability to handle fluids containing gas.
- EP2570340 discloses a riser tube having flow restrictors, such as, e.g. choke disks, arranged in its interior for restricting the flow of the fluids.
- gas-containing fluids may be transferred from the seabed to the underwater buffer reservoir, without requiring separation of the gas fraction at the seabed. This simplifies the structure to be deployed over the underwater source.
- the flow restrictors which are preferably arranged at regular intervals along the length of the riser tube, reduce the velocity of the fluid.
- US6412562 relates to electrical submersible well pumps inside a riser. As the production fluids flow up the well, the pressure drops and gases that were in solution become free gases. This invention of US6412562 is able to artificially boost the riser pressure to increase production and force some of the free gases back into solution.
- WO 2010/092145 Al relates to a method for converting hydrates buried in a water bottom into a marketable hydrocarbon composition.
- WO 2010/092145 Al is not concerned with pressure control in a riser, let alone pressure control along the length of a riser. Instead WO 2010/092145 Al seeks to reduce the amount of power required to lift the slurry and provides therefore a slurry lifting assembly comprising a slurry pump, which is actuated by the tailings stream.
- WO2013050138 (A2) relates to a riser system for transporting the slurry from a position adjacent to the seabed to a position adjacent to the sea surface.
- WO2013050138 (A2) aims to provide a riser system which can operate effectively and provides therefore a riser system for transporting the slurry from a position adjacent to the seabed to a position adjacent to the sea surface, the riser system comprising first and second risers; a slurry pump system to transport slurry up one of the risers and a waste water pump system to return waste water down one of the risers; wherein the slurry pump system and the waste water pump system are selectively connectable to each of the risers to allow each riser to be either a slurry riser or a waste water riser.
- WO2013050138 (A2) has for a drawback that gas hydrates entering the system will start dissociating under the influence of the reducing pressure during the assent to the surface. This impedes control of the flow in a riser.
- the invention aims to provide a deep sea mining method having an improved controllability of the slurry flow.
- Another object of the invention is to improve a known deep sea mining method in that a problem associated therewith is at least partly solved.
- Yet another object of the invention is to provide an alternative deep sea mining method.
- Maintaining a higher pressure inside the riser system beneficially adds stability to the slurry flow and reduces creation of free gas from sediments.
- US6412562 distinctively relate to operations concerning an oil- or gas-flow.
- the oil- and gas operations is a different technical field compared with mining operations mainly because of the different flow which imposes different requirements to systems and operations.
- the mining slurry flow differs with a oil or gas flow at least in that the slurry has a ranging density and is inhomogeneous.
- the solid content of the mining slurry is much higher. From system and operation perspective, the oil and gas operations do not require active pumping since the body of water provides an overpressure. Also means in relation to risk of a blow out in a oil and gas system is not relevant for a mining system.
- Deep sea here means seas having a depth of at least 500 meters, preferably at least 1000 meters.
- the method comprises the step measuring the pressure for providing a riser system pressure signal, and controlling the pressure in response to said pressure signal.
- the method comprises controlling the riser system pressure to a predefined riser system pressure threshold. Such a threshold may be dependent on the vertical position in the riser system.
- the maintaining a controlled riser system pressure comprises providing pressure control means .
- the pressure control means may comprise active and/or passive means.
- the pressure control means are selected from restriction, systems of bends, turbines, pumps used as turbines, and pumps.
- a series of pressure control means is provided. This enables to control pressure along the length of the riser system.
- the series of pressure control means is arranged along the length of the riser system for controlling pressure in the riser system. This improves pressure control along the length of the riser system.
- adjacent control means are arranged at a predefined mutual distance. This even more improves pressure control along the length of the riser system
- the method comprises recovering energy from the transported slurry through the pressure control means. This enables to recover possible energy surplus downstream, which surplus has been spend to pressure control upstream.
- the matter may comprise gashydrates.
- a deep sea mining system for use in the method according to the invention, the system comprising;
- an excavating system for excavating matter at a bottom of the body of water - a riser system for transporting a slurry of matter and water from the bottom of a body of water upwards to a slurry processing base, the riser system comprising an adjustable pump means proximate a bottom of a body of water,
- - pressure control means for maintaining a controlled riser system pressure higher than the environmental pressure inside the riser system for avoiding forming or release of gas and expanding of gas contained in the slurry during transporting the slurry
- the deep sea mining system comprises a series of pressure control means arranged along the length of the riser pipe for controlling pressure in the riser system. This improves pressure control along the length of the riser system.
- adjacent control means are arranged at a predefined mutual distance.
- the pressure control means comprise active and/or passive means.
- the pressure control means are selected from restrictor, systems of bends, turbines, pumps used as turbines, and pumps.
- the deep sea mining system comprises;
- the invention further relates to a device comprising one or more of the
