The following describes in detail the implementation procedure of each step of the underwater operation method provided in this embodiment:
step S1, as shown in FIG. 4 (A), the surface support vessel 100 is driven to a working position and the multi-function riser base module 400 is deployed to a first target position at the bottom of the water. In particular, the surface support vessel 100 may now be a secondary support vessel carrying the components required for each underwater operation.
In step S2, as shown in fig. 4 (B), the surface support ship 100 deploys the underwater operation device 300 to the underwater second target position. In particular, the surface support vessel 100 may be an auxiliary support vessel, and the underwater operation device 300 may be a mining vehicle or the like, according to actual requirements of underwater operation.
Step S3, as shown in fig. 4 (C), the surface support vessel 100 lifts the flexible jumper tube bundles 500 to a predetermined position in the water. Specifically, the surface support ship 100 may also be an auxiliary support ship at this time, and when the flexible bridging tube bundles 500 are respectively hoisted by using two hoisting cables, so that the positions of the ends of the flexible bridging tube bundles 500 can be conveniently obtained when the flexible bridging tube bundles 500 are subsequently installed, and the position change of the flexible bridging tube bundles 500 in the installation process is avoided.
In step S4, as shown in fig. 4 (D), the surface support vessel 100 deploys the underwater operation robot 600, and fixedly connects both ends of the flexible jumper tube bundle 500 with the multi-functional riser base module 400 and the underwater operation device 300, respectively, by the underwater operation robot 600. Specifically, the underwater operation robot 600 first inserts one end of the flexible jumper tube bundle 500 into the fixed joint of the underwater operation device 300 to achieve the fixed connection with the underwater operation device 300; docking plug 510 on the other end of flexible jumper tube bundle 500 is then inserted into the subsea connector of multi-function riser base module 400 to effect a secure connection with multi-function riser base module 400.
In step S5, as shown in fig. 4 (E), the surface support ship 100 deploys the riser hoisting device 200 into the water, and fixedly connects the end of the riser hoisting device 200 with the multi-functional riser base module 400 through the underwater operation robot 600. In particular, the surface support vessel 100 is a surface work vessel, such as a mining vessel, which is configured to collect material (e.g., ore) transferred from a material transfer riser and is thus fixedly coupled to one end of the riser lift 200. After the surface support vessel 100 is driven to a position corresponding to the multifunctional riser base module 400, the tip (free end) of the riser hoisting device 200 is lowered into the water; the underwater work robot 600 aligns the tip of the riser hoisting device 200 with the underwater docking head 420 of the multi-functional riser base module 400; the end of the riser hoisting device 200 is locked in place with the subsea abutment 420 by means of the hydraulic clasping mechanism of the multi-functional riser foundation module 400.
In step S6, as shown in fig. 4 (F), the multifunctional riser base module 400 is lifted to a preset height by the riser lifting device 200. Specifically, with reference to the above steps, the connection of the plurality of subsea operating devices 300 to the multi-function riser base module 400 may be accomplished. And, the multifunctional riser-base module 400 is lifted to a preset height by the riser-lifting device 200, so that the riser-lifting device 200 is always in a vertical state under the gravity action of the multifunctional riser-base module 400, thereby facilitating the bottom-up transportation of materials.
Thus, the underwater operation system is installed, and the underwater operation can be normally performed.
When the water surface support ship (water surface operation ship) needs to be returned to the dock for maintenance or encounters emergency situations such as extreme weather such as stormy waves and tsunamis, the water surface support ship needs to be separated from the multifunctional vertical pipe foundation module so as to ensure the safety of the water surface support ship. At this time, in the present embodiment, first, as shown in fig. 4 (G), the multifunctional riser base module 400 is lowered to the bottom of the water by the riser hoisting device 200; then, as shown in fig. 4 (H), the hydraulic clasping mechanism is controlled to be released to separate the end of the riser hoisting device 200 from the underwater docking head 420; finally, the riser hoisting device 200 is retrieved for the surface support vessel to return. When it is desired to connect the riser hoisting device 200 with the multifunctional riser base module 400 again, the above steps S5 and S6 are repeated.
In addition, in order to facilitate replacement of the underwater operation device 300 in order to improve the efficiency of the underwater operation considering that the underwater operation device 300 requires periodic maintenance or recovery replacement when an abnormal failure occurs, in the present embodiment, there is provided a method of replacing an underwater operation device, comprising:
first, as shown in fig. 4 (I), the surface support ship (auxiliary support ship) 120 hangs the temporary plugging module 700 into the water and deploys the underwater operation robot 600; when the temporary plugging module 700 is located at the water bottom, the end of the flexible jumper tube bundle 500 connected to the underwater operation device 300 is removed from the underwater operation device 300 by the underwater operation robot 600 and inserted into the temporary plugging module 700.
Then, as shown in fig. 4 (J), the surface support vessel (auxiliary support vessel) 120 is lowered to a hoist and a hoist is released, and the underwater operation device 300 is fixed to the hoist by the underwater operation robot 600, and the surface support vessel (auxiliary support vessel) 120 recovers the hoist to recover the underwater operation device 300; next, the new underwater operation device 300 is deployed to the second target position under the water according to the above step S2, and the end of the flexible jumper tube bundle 500 connected to the temporary plugging module 700 is removed from the temporary plugging module 700 by the underwater operation robot 600 and inserted into the underwater operation device 300.
Finally, the surface support vessel (auxiliary support vessel) 120 retrieves the temporary plugging module 700 and lifts the multi-functional riser-base module 400 to a predetermined height through the riser lifting device 200 according to the above-described step S6. Thereby completing the replacement of the underwater operation device 300.
In this way, the underwater operation system can be installed and the parts can be replaced conveniently and easily by the underwater operation robot 600 under water by using the surface operation ship 110 and the auxiliary support ship 120 to cooperate with each other. Although the above examples only show replacement steps for the subsea working device 300, the skilled person will be aware of the method of replacement of the subsea flexible jumper tube bundle 500 or the multi-function riser base module 400 in this way.
