[0034] During the operation of the ship, in order to effectively fix the deepwater blowout preventer group to prevent shaking and collapse, such as Figure 1-Figure 3 As shown, the present invention provides a hydraulic fixing and locking device, which includes two structural frames 1, two locking clamps 2, two first hydraulic cylinders 3 and a hydraulic control station 4.

[0035] Two structural frames 1 are spaced relative to each other and fixed to the hull. Two locking clamps 2 are rotatably mounted on the structural frames 1 at relative intervals, with each locking clamp 2 corresponding to each of the two structural frames 1. Two first hydraulic cylinders 3 are positioned one-to-one with each of the two structural frames 1, with one end of each first hydraulic cylinder 3 pivotally connected to the structural frame 1, and the piston rods of each first hydraulic cylinder 3 pivotally connected to the locking clamp 2. A hydraulic control station 4 is connected to the two first hydraulic cylinders 3 via a first oil circuit. The hydraulic control station 4 can control the movement of the first hydraulic cylinders 3 to position the locking clamp 2 in a fixed position, thereby clamping the deepwater blowout preventer stack, or in a released position, thereby releasing the deepwater blowout preventer stack.

[0036] During the vessel's operation, the hydraulic control station 4 is manipulated to control the movement of the first hydraulic cylinder 3, placing the locking clamp 2 in a fixed position, thereby firmly securing the deepwater BOP stack. This effectively secures the deepwater BOP stack and prevents it from shaking or collapsing. When the vessel is in position, the first hydraulic cylinder 3 is controlled to move the locking clamp 2 to the release position, releasing the deepwater BOP stack and ensuring its normal operation.

[0037] In some embodiments, the hydraulic fixing and locking device further includes a locking assembly 7, which is disposed on the structural frame 1 and is capable of locking the locking clamp 2 in a fixed position. The provision of the locking assembly 7 allows the locking clamp 2 to be secured when in the fixed position, thereby preventing the locking clamp 2 from deflecting under the action of external forces, which could result in the deepwater blowout preventer stack being unable to be securely held.

[0038] In some embodiments, the locking assembly 7 includes a second hydraulic cylinder 71 and a latch. A locking hole is defined in the locking clamp 2, and the latch is fixed to the piston rod of the second hydraulic cylinder 71. The second hydraulic cylinder 71 is mounted on the structural frame 1 and connected to the hydraulic control station 4 via a second oil circuit. The hydraulic control station 4 can control the movement of the piston rod of the second hydraulic cylinder 71 to drive the latch into or retract from the locking hole. When the first hydraulic cylinder 3 drives the locking clamp 2 to rotate to the fixed position, clamping the deepwater BOP stack, the piston rod of the second hydraulic cylinder 71 extends, allowing the latch to insert into the locking hole of the locking clamp 2, thereby restraining the locking clamp 2 and preventing rotation. When the deepwater BOP stack needs to be released, the piston rod of the second hydraulic cylinder 71 retracts, disengaging the latch from the locking hole. The first hydraulic cylinder 3 then activates to rotate the locking clamp 2 to the release position, thereby releasing the deepwater BOP stack. In this embodiment, a first electromagnetic reversing valve and a second electromagnetic reversing valve are provided in the hydraulic control station 4. The first electromagnetic reversing valve is connected to the first hydraulic cylinder 3, and the second electromagnetic reversing valve is connected to the second hydraulic cylinder 71. The actions of the first hydraulic cylinder 3 and the second hydraulic cylinder 71 can be controlled by the first electromagnetic reversing valve and the second electromagnetic reversing valve. Among them, the first electromagnetic reversing valve and the second electromagnetic reversing valve both adopt three-position four-way reversing valves. The specific hydraulic system layout belongs to conventional technical means and will not be elaborated on here. In other embodiments, the locking assembly 7 can be driven by a cylinder, or a motor-driven gear rack structure can be used. The pin is set on the rack, and the motor drives the gear to rotate and adjust the rack for lifting and lowering, thereby driving the pin to move. There are no excessive restrictions here.

[0039] In some embodiments, the locking clamp 2 has an arcuate groove. When the locking clamp 2 is in the fixed position, the fixed pipe of the deepwater BOP stack can be located in the arcuate groove. By providing the arcuate groove, it can cooperate with the circumference of the fixed pipe of the deepwater BOP stack, thereby effectively securing the fixed pipe of the deepwater BOP stack.

[0040] In some embodiments, elastic cushions 21 are provided on the walls of the arcuate grooves. These cushions 21 prevent scratches on the deepwater BOP stack's fixed pipes during the process of securing the locking clamp 2 to the pipes. Furthermore, the deformation of the cushions 21 increases friction, thereby stabilizing the deepwater BOP stack's fixed pipes. In this embodiment, the cushions 21 are made of rubber.

[0041] In some embodiments, a plurality of elastic buffer pads 21 are provided along the circumference of the arc-shaped groove. By providing a plurality of elastic buffer pads 21, the friction between the locking clamp 2 and the fixed pipe of the deepwater blowout preventer group can be further improved.

[0042] In some embodiments, the elastic cushion 21 is provided with a countersunk hole, and the wall of the arcuate groove is provided with a connecting hole. The fastener 22 passes through the countersunk hole and connects to the connecting hole. This arrangement facilitates the installation of the elastic cushion 21 using the fastener 22. Furthermore, the elastic cushion 21 can be replaced if it becomes worn.

[0043] In some embodiments, the structural frame 1 has a mounting plate 11 with a first mounting hole formed thereon, through which the connecting bolt 5 passes to connect to the hull. The mounting plate 11 facilitates installation of the structural frame 1 on the hull.

[0044] In some embodiments, a locking plate 6 is provided on the side of the hull facing away from the mounting plate 11. The hull has a through-hole opposite the first mounting hole, and the locking plate 6 has a second mounting hole opposite the through-hole. Connecting bolts 5 pass through the first mounting hole, the through-hole, and the second mounting hole, respectively, to connect with nuts. The provision of the locking plate 6 increases the stress-bearing area after the structural frame 1 is installed, ensuring uniform stress at the locations where the hull and structural frame 1 are mounted.

[0045] This embodiment also provides a vessel, comprising a hull and the above hydraulic fixing and locking device, wherein the hydraulic fixing and locking device is arranged on the hull and can effectively fix the deepwater blowout preventer group to prevent shaking and collapse.

[0046] Obviously, the above embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention, and are not intended to limit the implementation methods of the present invention. A person skilled in the art will be able to make other variations or modifications based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
