DETAILED DESCRIPTION

[0017] In order to facilitate understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. Embodiments of the present application are provided in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thorough and comprehensive.

[0018] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application.

[0019] It will be appreciated that spatial relationship terms such as "under," "beneath," "below," "under," "above," "above," etc., may be used herein to describe the relationship of an element or feature shown in the figures to other elements or features. It will be appreciated that, in addition to the orientations shown in the figures, spatial relationship terms also include different orientations of the device in use and operation. For example, if the device in the accompanying drawings is flipped, an element or feature described as "under other elements" or "under it" or "under it" will be oriented as being "above" the other elements or features. Thus, the exemplary terms "under" and "under" may include both upper and lower orientations. In addition, the device may also include additional orientations (e.g., rotated 90 degrees or other orientations), and the spatial descriptors used herein are interpreted accordingly.

[0020] It should be noted that when an element is considered to be "connected" to another element, it can be directly connected to the other element, or connected to the other element through an intermediate element. The "connection" in the following embodiments should be understood as "electrical connection", "communication connection", etc. if the connected circuits, modules, units, etc. have electrical signals or data transmission between each other.

[0021] When used herein, the singular forms "a", "an", and "said / the" may also include plural forms, unless the context clearly indicates otherwise. It should also be understood that the terms "include / comprise" or "have" etc. specify the presence of stated features, wholes, steps, operations, components, parts or combinations thereof, but do not exclude the possibility of the presence or addition of one or more other features, wholes, steps, operations, components, parts or combinations thereof.

[0022] In the actual operation of deep-sea mining projects, mining vehicles are deployed and recovered in the stern area, while hoses are deployed and recovered in the side area. The flexible pipe needs to be docked with the mining vehicle on the surface support ship and deployed and recovered synchronously with the mining vehicle. The operation process is affected by the wind and waves at sea. Since the hose posture is difficult to control and there is a lack of anti-sway measures, there are risks such as collision and entanglement between the hose and the ship.

[0023] Based on this, an embodiment of the present application provides a system and method for docking, laying and recovering a flexible pipeline for deep-sea mining, so as to reduce the operational risks during the docking, laying and recovering process of the hose.

[0024] Figure 1 The schematic diagram of the structure of a deep-sea mining flexible pipeline docking and deployment recovery system provided by an embodiment of the present application is shown. Figure 2 Shows Figure 1 A top view of the deep-sea mining flexible pipeline docking and deployment recovery system. Figure 3 A schematic diagram showing the state of the hose deployment process before the hose is docked with the mining vehicle in an embodiment of the present application is shown. Figure 4 Shows Figure 3 A top view of the hose deployment process before the middle hose is docked with the mining vehicle. For ease of explanation, only the parts related to the embodiment are shown in the figure.

[0025] See also Figures 1 to 4 A deep-sea mining flexible pipeline docking and deployment and recovery system provided in one embodiment of the present application includes a hose deployment and recovery device 10, a mining vehicle deployment device 20, a lifting device 30 and a constant tension control device 40 arranged on a ship platform. The ship platform has a mining vehicle deployment preparation area, and a plurality of constant tension control devices 40 are arranged in the mining vehicle deployment preparation area. The constant tension control device 40 is used to provide constant tension to the hose L during the docking process between the hose L and the mining vehicle K, so as to control the docking posture of the hose L. The hose deployment and recovery device 10 is used to deploy and recover the hose L. The mining vehicle deployment device 20 is used to deploy and recover the mining vehicle K. The lifting device 30 is used to provide operating power to the hose L and the mining vehicle K during the docking and deployment and recovery process.

[0026] It should be noted that the mining vehicle deployment preparation area is close to the stern, and the mining vehicle deployment preparation area refers to the area where the mining vehicle K, the constant tension control device 40 and part of the lifting device 30 are arranged. The constant tension control device 40 located on the mining vehicle deployment preparation area is used to connect the head end of the hose L.

[0027] During the docking and laying and recovery process between the hose L and the mining vehicle K, the hose L is laid out to the side of the ship by the hose laying and recovery device 10, and the head end of the hose L is hoisted to the mining vehicle laying preparation area by the lifting device 30. The head end of the hose L is connected to the constant tension control device 40 located in the mining vehicle laying preparation area to provide constant tension to the hose L, and the head end of the hose L is docked with the mining vehicle K. The mining vehicle K that has been docked with the hose L is laid by the mining vehicle laying and recovery device 20, so as to realize the synchronous laying of the mining vehicle K and the hose L. After the mining operation is completed, the mining vehicle K and the hose L are recovered by the hose laying and recovery device 10 and the mining vehicle laying and recovery device 20.

[0028] In this embodiment, a plurality of constant tension control devices 40 are arranged in the preparation area for deploying the mining vehicle. During the docking and installation process between the head end of the hose L and the mining vehicle K, the constant tension control device 40 is used to pull and tension the hose L, thereby realizing anti-sway and anti-sway and posture control of the hose L, which can greatly improve the safety and efficiency of the docking and installation between the hose L and the mining vehicle K and the deployment and recovery operations of the hose L and the mining vehicle K.

[0029] Figure 5 A schematic diagram showing the state of the hose and the mining vehicle after docking in the embodiment of the present application is shown. Figure 6 Shows Figure 5 The top view of the middle hose and the mining vehicle after docking, for the convenience of explanation, only the part related to the embodiment is shown.

[0030] Continue reading Figure 1 and Figure 3 , and combined with Figure 5 and Figure 6 In some embodiments, the constant tension control device 40 includes a wire rope winch. At least two wire rope winches are arranged in the mining vehicle deployment preparation area, and the head end of the hose L is connected by a wire rope to control the alignment of the head end of the hose L with the flange of the mining vehicle K.

[0031] It should be noted that the wire rope winch includes structures such as a winch, a wire rope, and a constant tension control system. In this embodiment, two wire rope winches are set in the mining vehicle deployment preparation area, and three or four can be set in other embodiments, which can be set according to actual conditions. In addition, in this embodiment, the lifting device 30 includes a lifting crane 31. The lifting crane 31 can pull the head end of the hose L to the mining vehicle deployment preparation area, so that the constant tension control device 40 located in the mining vehicle deployment preparation area is connected to the head end of the hose L.

[0032] Specifically, when the hoisting crane 31 lifts the head end of the hose L to the mining vehicle deployment preparation area, the hose L remains in the hoisting state, and the wire ropes of the two wire rope winches are manually connected symmetrically to the head end flange of the hose L. Since the hose L is long and heavy, it is difficult to manually control the docking posture of the hose L when the hose L and the mining vehicle K are docked. When the hose L and the mining vehicle K are docked, the constant tension function of the wire rope winch is activated, and the head end flange of the hose L can be quickly controlled to be aligned with the flange interface of the mining vehicle K by pulling and tensioning the hose L with the wire rope, and then the two are fixed by bolts, such as Figure 5 As shown in the figure, the docking process of the hose L is prevented from shaking and swaying, the risk of collision and entanglement between the hose L and the ship is reduced, and the safety and operation efficiency of the hose L and the mining vehicle K in docking, deployment and recovery are improved as a whole.

[0033] Continue reading Figures 1 to 4 In some embodiments, the hose laying and recovery device 10 includes a hose winch 12, a guide roller 13 and a traction guide device 14 provided on the hose laying platform 11. The hose winch 12 is used to release the hose L, and the guide roller 13 and the traction guide device 14 are used to guide the discharge of the hose L.

[0034] It should be noted that the hose winch 12 and the guide roller 13 are arranged on the hose laying platform 11, the traction guide device 14 is located on the side of the guide pulley 13 away from the hose winch 12, and one side of the traction guide device 14 is connected to the hose laying platform 11, and the other side is located outside the ship's side. In this embodiment, the traction guide device 14 is constructed as an arc-shaped bridge member for guiding the release of the hose L.

[0035] Specifically, the hose L is released by the hose winch 12 and transmitted to the traction guide device 14 through the guide roller 13. The continuously released hose L is laid out to the side of the ship through the traction guide device 14. At the same time, the head end of the hose L is connected to the hoisting crane 31. When water is put under the hose L, the head end of the hose L is towed to the mining vehicle laying preparation area through the hoisting crane 31, so as to facilitate the docking of the hose L and the mining vehicle K. In this way, by providing the hose laying platform 11, the hose winch 12, the guide roller 13 and the traction guide device 14, the release and guiding operation of the hose L can be quickly completed.

[0036] Continue reading Figure 3 and Figure 4 In some embodiments, a buoyancy block S is provided on the hose L; at least two constant tension control devices 40 are provided on the hose placing platform 11, and the at least two constant tension control devices 40 are used to connect the buoyancy block S to control the entry posture of the hose L and the buoyancy block S into the water.

[0037] It should be noted that, in the present embodiment, two wire rope winches are provided on the hose laying platform 11, and in other embodiments, three or four winches may be provided, and the specific arrangement may be made according to actual conditions.

[0038] Specifically, in the present embodiment, the lifting device 30 further includes a telescopic crane 32. The telescopic crane 32 has a telescopic arm, with a more accurate coverage range and flexible operation. Since the buoyancy block S is large and heavy, the buoyancy block S can be hoisted to the vicinity of the hose laying platform 11 by the telescopic crane 32, and the buoyancy block S is manually tied to the corresponding position of the hose L, and the steel wire ropes of the two wire rope winches are symmetrically connected to the two sides of the buoyancy block S, and the steel wire ropes are detachably connected to the movable hook rings of the buoyancy block S through hooks. When the hose L and the buoyancy block S are put into the water from the side of the ship, the constant tension function of the wire rope winch is started to control the water entry posture of the hose L and the buoyancy block S. When each buoyancy block S is put into the water, the movable hook ring of the buoyancy block S is opened by a long rod to retract the steel wire rope. In this way, the water entry postures of multiple buoyancy blocks S and hoses L are repeatedly controlled to avoid collision with the ship due to the influence of sea breeze, which plays a role in anti-sway and anti-sway.

[0039] Figure 7 A schematic diagram showing the use status of the umbilical cable winch and the A-frame crane in the embodiment of the present application is shown. Figure 8 A schematic diagram of the state of synchronous deployment of a mining vehicle and a hose in an embodiment of the present application is shown. For ease of explanation, only the parts related to the embodiment are shown in the figure.

[0040] Continue reading Figure 1 and Figure 5 , and combined with Figure 7 and Figure 8 In some embodiments, the mining vehicle deployment and recovery device 20 includes an umbilical cable winch 21 and a cable arranger (not shown in the figure). The lifting device 30 also includes an A-frame crane 33. The umbilical cable winch 21 is used to output the umbilical cable and pass through the cable arranger, connect with the A-frame crane 33, and connect the umbilical cable to the mining vehicle K.

[0041] It should be noted that the A-frame crane 33 is a common crane and includes structures such as a base, an extension mechanism, a variable amplitude mechanism, a swing-stop mechanism, a clamping and rotating mechanism, and a clamping and locking mechanism. Figure 1 The dotted circle in the figure indicates the range of motion r of the A-frame crane 33. In addition, in combination with the contents of the aforementioned embodiment, when the hose L and the buoyancy block S are launched into the water, the head end of the hose L is lifted by the hoisting crane 31 and bypasses the A-frame crane 33, and then dragged to the mining vehicle K, so that the hose L can be docked with the mining vehicle K under the action of the wire rope winch.

[0042] Specifically, Figure 7As shown, in the early stage of the deployment of the mining vehicle K, the umbilical cable is released by the umbilical cable winch 21, passes through the cable arranger, and is sequentially connected to the clamping and locking mechanism and the anti-swing mechanism of the A-frame crane 33, and the umbilical cable is connected to the mining vehicle K. Further, as Figure 5 As shown, the first end of the hose L is connected to the mining vehicle K. Figure 8 As shown, under the action of the A-frame crane 33 and the umbilical cable winch 21, the mining vehicle K and the hose L are synchronously deployed and recovered.

[0043] Fig. 9 A schematic diagram of the structure of a deep-sea mining flexible pipeline docking and deployment recovery system according to another embodiment of the present application is shown. Fig.10 Shows Fig. 9 A top view of the deep-sea mining flexible pipeline docking and deployment recovery system. Fig.11 A schematic diagram showing the state of the hose deployment process before the hose is docked with the intermediate cabin in the embodiment of the present application is shown. Fig.12 Shows Fig.11 A top view of the hose deployment process before the middle hose is docked with the middle cabin. For ease of explanation, only the part related to the embodiment is shown.

[0044] See also Figures 9 to 12 In another embodiment of the present application, a deep-sea mining flexible pipeline docking and deployment and recovery system is provided, including a hose deployment and recovery device 10, a mining vehicle deployment device 20, a lifting device 30 and a constant tension control device 40 arranged on a ship platform. The ship platform has a mining vehicle deployment preparation area and an intermediate cabin deployment preparation area, and a plurality of constant tension control devices 40 are respectively arranged in the mining vehicle deployment preparation area and the intermediate cabin deployment preparation area. The constant tension control device 40 is used to provide constant tension to the hose L during the docking process between the hose L and the mining vehicle K and the docking process between the hose L and the intermediate cabin E, so as to control the docking posture of the hose L. The hose deployment and recovery device 10 is used to deploy and recover the hose L. The mining vehicle deployment device 20 is used to deploy and recover the mining vehicle K. The lifting device 30 is used to provide operating power to the hose L and the mining vehicle K during the docking and deployment and recovery process.

[0045] The difference between this embodiment and the previous embodiment is that in this embodiment, a preparatory area for placing an intermediate cabin is set on the ship platform, a plurality of constant tension control devices 40 are set in the preparatory area for placing an intermediate cabin, and the docking installation between the end of the hose L and the intermediate cabin E is completed under the constant tension function of the constant tension control device 40, while the docking installation process between the head end of the hose L and the mining vehicle K is the same as that of the previous embodiment. Fig.13 and Fig.14 As shown, the docking posture control between the hose L and the mining vehicle K, and the hose L and the intermediate cabin E can be realized. Thus, the mining vehicle K, the hose L and the intermediate cabin E can be deployed and recovered synchronously.

[0046] In some embodiments, Fig.10 As shown, the constant tension control device 40 includes a wire rope winch. At least three wire rope winches are arranged in the intermediate cabin deployment preparation area, and the end of the hose L is connected by a wire rope to control the alignment of the end of the hose L and the flange of the intermediate cabin E. Specifically, in this embodiment, three wire rope winches are arranged in the intermediate cabin deployment preparation area, and four or five wire rope winches may be arranged in other embodiments, which can be arranged according to actual conditions.

[0047] Furthermore, the lifting device 30 includes a lifting crane 31 and a telescopic crane 32. The telescopic crane 32 is used to lift the end of the hose L to the intermediate cabin deployment preparation area so that the end of the hose L is connected to the constant tension control device 40. The lifting crane 31 has a wire rope pulley for deploying and recovering the intermediate cabin E.

[0048] Specifically, Figures 9 to 11 As shown, after the hose deployment and recovery device 10 completely releases the hose L, the end of the hose L is connected to the telescopic crane 32, and the end of the hose L is dragged to the intermediate cabin deployment preparation area by the telescopic crane 32. Fig.13 and Fig.14 As shown, the end of the hose L is manually connected to the three wire rope winches located in the preparation area for the deployment of the middle tank, and the constant tension function of the wire rope winches is activated. The end of the hose L is pulled and tensioned by the wire rope to facilitate manual alignment of the end flange of the hose L and the flange interface of the middle tank E, and then the two are fixed by bolts. In this way, the docking process of the hose L plays an anti-sway and anti-sway role, reducing the risk of collision and entanglement between the hose L and the ship, and improving the overall efficiency and safety of the hose L, mining vehicle K and the middle tank E in docking and deployment and recovery.

[0049] In addition, after the hose L is docked and installed with the mining vehicle K, and the hose L is docked with the intermediate cabin E, as shown in FIG. Fig.15 and Fig.16 As shown, the mining vehicle K is hoisted to the side of the ship by the A-frame crane 33, and the intermediate cabin E is hoisted to the side of the ship by the wire rope pulley of the lifting crane 31, and the hose L follows, and then the connection between the wire rope and the intermediate cabin E is released outside the ship, and the mining vehicle K, the hose L and the intermediate cabin E are further deployed to the seabed, as shown in FIG. Fig.17 shown.

[0050] Continue reading Figures 1 to 4 Based on the same inventive concept, an operating method of a deep-sea mining flexible pipeline docking and deployment recovery system is provided in one embodiment of the present application, including: (1) The hose L is laid out to the side of the ship by the hose laying and recovery device 10, and the head end of the hose L is hoisted to the mining vehicle laying preparation area by the lifting device 30.

[0053] (4) After the mining operation is completed, the mining vehicle K and the hose L are recovered by the mining vehicle deployment and recovery device 20 and the hose deployment and recovery device 10 .

[0054] In this embodiment, during the docking and installation process of the head end of the hose L and the mining vehicle K, a constant tension control device 40 is used to pull and tension the hose L, thereby achieving anti-sway and anti-sway and posture control of the hose L, which can greatly improve the efficiency and safety of the docking and installation of the hose L and the mining vehicle K and the deployment and recovery operations of the hose L and the mining vehicle K.

[0055] Continue reading Figures 9 to 12 In another embodiment of the present application, a method for operating a deep-sea mining flexible pipeline docking and deployment recovery system is provided, comprising: (1) The hose L is laid out to the side of the ship by the hose laying and recovery device 10, and the head end of the hose L is hoisted to the mining vehicle laying preparation area by the lifting device 30.
