Description

Technical Field

[0001] The present invention relates to the technical field of submarine cables, and in particular to a submarine cable anchoring device and a submarine cable anchoring method. Background Art

[0002] With the continuous development of marine energy, more and more offshore oil and gas platforms are being built to develop marine resources. Since oil and gas platforms are built on the sea, in order to ensure that the oil and gas platforms can communicate normally with the outside world, submarine cables are usually used to interconnect the platforms.

[0003] Due to the special working environment of submarine cables, many special factors need to be considered when designing and manufacturing submarine cables, such as the scouring of high-salinity seawater, the rocky and rugged seabed, and the ecology of marine animals. In order to protect the safety of submarine cables, submarine cables are equipped with protective layers such as armor layers and insulation layers to protect the conductors inside. With the layers stacked up, the submarine cable is heavy and thick as a whole. When the submarine cable lands on the oil and gas platform, the conductor inside the submarine cable needs to be connected to the explosion-proof box on the oil and gas platform. At this time, the protective layer on the outside of the submarine cable becomes a burden, and it is usually necessary to peel off part of the protective layer to facilitate the connection of the conductor.

[0004] Taking the anchoring method of a certain submarine cable as an example, first, measure the distance between the submarine cable anchoring point on the platform and the explosion-proof box; second, strip off the protective layer of the corresponding length of the submarine cable; then, fix the submarine cable to the platform through a fixing device; finally, pull the exposed conductor of the submarine cable to the explosion-proof box and connect the two. Since the distance between the submarine cable anchoring point and the explosion-proof box on different oil and gas platforms is different, each installation requires a lot of time for measurement, and the operation efficiency is low. At the same time, this method has high requirements for measurement accuracy, and it is often difficult to strip off the protective layer of the appropriate length at one time. When the submarine cable is anchored, if the fixing device needs to be readjusted due to length error, not only is the operation difficult, but it is also easy to damage the submarine cable.

[0039] Reference Figure 1 and Figure 2 As shown, the present invention provides a submarine cable anchoring device, including an anchor 10 and an anchoring seat 30.

[0040] The anchor 10 is used to cooperate with the anchor seat 30 to anchor the target submarine cable 20. The target submarine cable 20 is a submarine cable that needs to land on the target platform, be anchored, and be connected to the target object. The target submarine cable 20 includes a conductor 21 and an armor layer arranged outside the conductor 21, and the armor layer includes an armor steel wire 22.

[0041] When landing on the target platform, the target submarine cable 20 needs to be processed to expose a certain length of the conductor 21, so that after landing, the staff can conveniently connect the conductor 21 with the target component. In the present invention, the target component is an explosion-proof box arranged on the target platform.

[0042] The anchor 10 is detachably connected to the target submarine cable 20 so as to adjust the relative position of the anchor 10 and the target submarine cable 20 and change the length of the conductor 21 exposed by the target submarine cable 20. When the anchor 10 is connected to the target submarine cable 20, the anchor 10 can also play a role in protecting the target submarine cable 20 to prevent it from being damaged. Those skilled in the art can set different anchors 10 according to actual needs, as long as the two can be detachably connected and the position adjustment can be achieved.

[0043] The anchoring seat 30 is arranged on the target platform, and is used to anchor the target submarine cable 20. The anchoring seat 30 includes a first sub-seat 301 and a second sub-seat 302. The first sub-seat 301 is provided with a clamping step 311 corresponding to the anchor 10. By providing the clamping step 311, the anchor 10 is temporarily placed, so that the staff can handle the target submarine cable 20 again to adjust the length of the conductor 21 when the reserved conductor 21 is not long enough and cannot be connected. The second sub-seat 302 is detachably connected to the first sub-seat 301 to adjust the anchor 10 and the target submarine cable 20.

[0044] Reference Figure 2 and Figure 3 As shown, the working state of the anchor seat 30 includes a first state and a second state. When the anchor seat 30 is in the first state, the first sub-seat 301 is set on the target platform. Preferably, the second sub-seat 302 is separated from the first sub-seat 301. At this time, the anchor 10 and the target submarine cable 20 are pulled so that the anchor 10 is set on the clamping step 311 of the first sub-seat 301 to temporarily anchor the target submarine cable 20 and the anchor 10. When the reserved conductor 21 is not long enough and the conductor 21 and the explosion-proof box cannot be connected, the anchor 10 and the target submarine cable 20 are adjusted to change the length of the exposed conductor 21. When the anchor seat 30 is in the second state, the second sub-seat 302 is connected to the first sub-seat 301 to anchor the target submarine cable 20 and the anchor 10 to ensure the anchoring strength.

[0045] The submarine cable anchoring device of the present invention, by providing the anchor 10 and the anchor seat 30, can first place the anchor 10 connected to the target submarine cable 20 on the clamping step 311 of the first sub-seat 301 to temporarily place the anchor 10 when the target submarine cable 20 is landed on the platform, anchored and connected. If the conductor 21 can be successfully connected to the explosion-proof box, the second sub-seat 302 is assembled with the first sub-seat 301 to achieve the anchoring of the anchor 10 and the target submarine cable 20. If the length of the conductor 21 is not enough to connect the explosion-proof box, the anchor 10 and the target submarine cable 20 can be conveniently adjusted to change the length of the exposed conductor 21.

[0046] Compared with the device that is dismantled and reinstalled after anchoring due to insufficient length of the conductor 21, the submarine cable anchoring device of the present invention reduces the difficulty of adjusting the length of the conductor 21 while ensuring the anchoring effect, and is not easy to damage the target submarine cable 20 during adjustment. Since the adjustment difficulty is reduced and the adjustment can be quickly achieved, the requirements for distance measurement accuracy are reduced, and the operating efficiency of the entire anchoring process is improved.

[0047] Reference Figure 4 As shown, in some embodiments of the submarine cable anchoring device of the present invention, the first sub-seat 301 and the second sub-seat 302 have the same structure, and both include a flange component 31 and a limiting component 32.

[0048] The flange component 31 is used to connect the target platform to achieve stable and reliable anchoring. Specifically, a flange connection portion 312 is provided on the flange component 31, and the flange connection portion 312 is used to be detachably connected to the target platform. Preferably, the flange connection portion 312 is set as a bolt hole so that bolts can be set to fix the sub-seat to the platform. Exemplarily, when in use, the first sub-seat 301 is first fixed to the platform through the flange connection portion 312 to cooperate with the anchor 10 to achieve temporary anchoring; after the conductor 21 and the explosion-proof box are connected, the second sub-seat 302 is respectively connected to the first sub-seat 301 and the platform to achieve anchoring. A flange half hole 313 is provided at the edge of the flange component 31, and the flange half hole 313 is used to set the target submarine cable 20. Preferably, the hole formed by the two flange half holes 313 is matched with the clearance of the target submarine cable 20 so that the target submarine cable 20 can pass.

[0049] The limiting component 32 is used to protect and limit the anchor 10, and is also used to achieve the connection between the two sub-seats. Specifically, the limiting component 32 is arranged on the flange surface of the flange component 31, the limiting component 32 is arranged on the outside of the flange half hole 313, the limiting component 32 is arranged around the flange half hole 313, and the clamping step 311 includes the enclosed limiting component 32 and the flange component 31. In the case of temporary anchoring, the target submarine cable 20 is arranged in the flange half hole 313 of the first sub-seat 301, and the anchor 10 is arranged on the clamping step 311 of the first sub-seat 301, and is limited and protected by the limiting component 32. After completing the connection between the conductor 21 and the explosion-proof box, the second sub-seat 302 is installed, so that the target submarine cable 20 is arranged in the hole spliced ​​by the flange half holes 313 of the two sub-seats, and the anchor 10 is arranged on the clamping step 311 of the two sub-seats. At this time, the limiting components 32 of the two sub-seats enclose to form an anchoring space to limit and protect the anchor 10 located inside.

[0050] The limiting component 32 is provided with a limiting connection part 321, and the limiting connection part 321 is used for disassembling and connecting another limiting component 32. Preferably, the limiting connection part 321 is provided with a bolt hole so that a fastener such as a bolt can be arranged therein to achieve the fixation of the two sub-seats.

[0051] Preferably, there is a gap between the limiting component 32 and the anchor 10. Preferably, a protective pad 33 is provided inside the limiting component 32 to provide a protective effect during assembly and prevent the component from being damaged. Preferably, along the axial direction of the target submarine cable 20, the size of the limiting component 32 is smaller than the size of the anchor 10. Preferably, the anchor 10 is configured as a cylindrical structure, and the inner wall surface of the limiting component 32 close to the anchor 10 is configured as an arc surface so that the two are adapted.

[0052] Reference Figure 5As shown, in the submarine cable anchoring device of the present invention, in some embodiments, the anchor 10 includes a clamping member 11 and a compression armor member 12.

[0053] The clamping member 11 is used to clamp and protect the target submarine cable 20. Specifically, the clamping member 11 is provided with a clamping channel 111, and the target submarine cable 20 is arranged in the clamping channel 111. In actual use, the clamping member 11 is arranged on the clamping step 311. The armor pressing member 12 is arranged at one end of the clamping member 11 away from the anchor seat 30, and the armor pressing member 12 is detachably connected to the clamping member 11.

[0054] The pressure armor member 12 includes at least one pressure armor component 121. The pressure armor component 121 is provided with a pressure armor hole 1212 and a pressing portion 1213. The conductor 21 is arranged in the pressure armor hole 1212 so as to pass through and be connected with the explosion-proof box.

[0055] The pressing part 1213 is used to press and fix the armor wire 22 of the target submarine cable 20, so as to prevent the target submarine cable 20 from axial movement. Those skilled in the art can set the structure of the pressing part 1213 according to actual needs. For example, the pressing part 1213 is set as a planar structure to press the armor wire 22.

[0056] When there are multiple armor pressing parts 121, multiple armor pressing parts 121 are stacked in sequence along the axial direction of the clamping channel 111. When facing the target submarine cable 20 with multiple layers of armor, the corresponding armor steel wire 22 can be pressed and fixed by the pressing part 1213 of the corresponding armor pressing part 121, so as to better adapt to the structure of the target submarine cable 20 and improve safety and reliability. Preferably, the opening surface of the armor pressing hole 1212 contacting the armor steel wire 22 is provided with an arc structure. Preferably, the radial dimensions of the clamping member 11 and the armor pressing member 12 are the same.

[0057] Further, see Figure 6 and Figure 8 As shown, in the submarine cable anchoring device of the present invention, in some embodiments, the compression armor component 121 includes two compression armor sub-components 1211 that are assembled together, and the assembly surfaces of the compression armor sub-components 1211 are provided with first compression armor half holes 1215, and the assembled two first compression armor half holes 1215 form a compression armor hole 1212. By setting the compression armor component 121 as a split structure, during assembly, the compression armor sub-components 1211 can be assembled from the radial side of the target submarine cable 20. Compared with the integrated structure, the assembly difficulty is reduced and the operation efficiency is improved.

[0058] Further, see Figure 7 As shown, when there are multiple compression armor components 121 and they are split structures, the joint surfaces of two adjacent compression armor components 121 are set at an angle. By setting this structure, it is possible to avoid the misalignment of the compression armor components 1211 due to parallel joint surfaces, effectively improving reliability.

[0059] Further, see Fig. 9 As shown, in some embodiments of the submarine cable anchoring device of the present invention, the compression armor component 12 further includes two compression armor connection sub-components 122 that are assembled. A second compression armor half hole 1221 is provided on the assembled surface of each compression armor connection sub-component 122, and the conductor 21 is arranged in the two assembled second compression armor half holes 1221 so that it can pass through and connect with the explosion-proof box. By providing the compression armor connection sub-component 122, on the one hand, the detachable connection between the compression armor component 121 and the clamping component 11 can be realized; on the other hand, its split structure can facilitate the assembly from the radial side of the target submarine cable 20, reducing the assembly difficulty and improving the working efficiency.

[0060] The armor-pressing connecting sub-component 122 is provided with a first countersunk hole 1222 and a first mounting hole 1223, and the clamping member 11 is provided with a second mounting hole 1122 corresponding to the first countersunk hole 1222. The armor-pressing connecting sub-component 122 is detachably connected to the clamping member 11 through fasteners provided in the first countersunk hole 1222 and the second mounting hole 1122. The first countersunk hole 1222 is provided to accommodate the corresponding fasteners, so as to avoid the fasteners protruding and affecting the assembly of the armor-pressing connecting sub-component 122 and the armor-pressing component 121. The armor-pressing component 121 is provided with a third mounting hole 1214 corresponding to the first mounting hole 1223. The armor-pressing connecting sub-component 122 and the armor-pressing component 121 are detachably connected through fasteners provided in the first mounting hole 1223 and the third mounting hole 1214.

[0061] Further, see Fig.10 As shown, in the submarine cable anchoring device of the present invention, in some embodiments, the clamping member 11 includes a plurality of clamping sub-members 112 that are assembled, the plurality of clamping sub-members 112 are detachably connected, a clamping groove 1121 is provided on the assembled surface of the clamping sub-members 112, and the assembled plurality of clamping grooves 1121 form a clamping channel 111. Preferably, only two clamping sub-members 112 are provided. By providing this structure, the clamping member 11 is a split structure, and during assembly, the clamping sub-members 112 can be assembled from the radial side of the target submarine cable 20, thereby reducing the assembly difficulty and improving the operation efficiency.

[0062] Preferably, a plurality of third countersunk holes 1123 are provided on the clamping sub-component 112, and the plurality of third countersunk holes 1123 are sequentially arranged along the axial direction of the clamping sub-component 112, so that corresponding bolts are arranged through the third countersunk holes 1123 to realize the disassembly connection of the two clamping sub-components 112. Under the premise of ensuring the connection effect, the interference of the bolts with the limiting component 32 of the anchor seat 30 can be avoided. Preferably, a clamping chamfer 1124 is provided at the end of each clamping sub-component 112, so that the clamping chamfer 1124 cooperates with the limiting component 32 of the anchor seat 30, so that the position of the clamping sub-component 112 is easier to adjust, so as to adjust the length of the conductor 21 and improve the working efficiency. Preferably, a friction thread 1125 is provided in the clamping groove 1121, so as to better realize the clamping of the target submarine cable 20 and improve the stability and reliability.

[0063] Reference Fig.11 As shown, the submarine cable anchoring device of the present invention, in some embodiments, further includes a traction member 40. The traction member 40 is arranged at one end of the compression armor member 12 away from the clamping member 11, and the traction member 40 is detachably connected with the compression armor member 12, and the traction member 40 is used to pull the target submarine cable 20 to move. Compared with using additional components to connect and pull the target submarine cable 20, by arranging a detachable traction member 40 on the compression armor member 12, on the one hand, it is convenient for the traction member 40 to cooperate with the compression armor member 12. Specifically, when it is necessary to adjust the length of the conductor 21, it is only necessary to maintain the traction of the target submarine cable 20 through the traction member 40, so that the clamping member 11 is separated from the clamping step 311 of the first sub-seat 301. Subsequently, the relative position of the clamping member 11 and the target submarine cable 20 is adjusted, so that the clamping member 11 is separated from the compression armor member 12 and is set on the clamping step 311 again. Next, the target submarine cable 20 is processed to expose a longer conductor 21. After the conductor 21 is connected, the relative positions of the compression armor 12 and the target submarine cable 20 are adjusted to fix the compression armor 12 and the clamping member 11. Finally, the redundant armor steel wire 22 is processed and the second sub-seat 302 is installed to achieve anchoring. On the other hand, it is also convenient to face multiple target submarine cables 20, and only one traction member 40 is required to cooperate with multiple compression armor members 12, thereby reducing costs and avoiding the waste of disposable traction heads that are thrown away after use.

[0064] Further, see Fig.12As shown, in the submarine cable anchoring device described in the present invention, in some embodiments, the traction component 40 includes two traction sub-components 41 that are spliced ​​together. A traction half hole 411 is provided on the spliced ​​surface of the traction sub-component 41, and the conductor 21 is provided in the two spliced ​​traction half holes 411 so that it can pass through and connect with the explosion-proof box. By providing this split structure, during assembly, the traction sub-component 41 can be spliced ​​from the radial side of the target submarine cable 20, which reduces the difficulty of assembly and improves the working efficiency.

[0066] On the other hand, an embodiment of the present invention further provides a method for anchoring a submarine cable, comprising the following steps:

[0067] Connecting the anchor 10 and the target submarine cable 20;

[0068] Pull the anchor 10 and the target submarine cable 20, so that the anchor 10 is set on the clamping step 311 of the first sub-seat 301, so as to temporarily anchor the target submarine cable 20 and the anchor 10; wherein the first sub-seat 301 is set on the target platform;

[0069] Connecting the target component and the conductor 21 of the target submarine cable 20; wherein, if the exposed length of the conductor 21 is less than the length required for connection, adjusting the relative position of the anchor 10 and the target submarine cable 20, and the exposed length of the conductor 21, until the length required for connection is less than or equal to the exposed length of the conductor 21;

[0070] The second sub-seat 302 is connected to the first sub-seat 301 to anchor the target submarine cable 20 and the anchor 10 .

[0071] Working principle:

[0072] First, process the target submarine cable 20 to expose a certain length of the conductor 21. Secondly, install the anchor 10. Specifically, first clamp the target submarine cable 20 with the clamping sub-component 112, and set bolts in the corresponding third countersunk hole 1123 to fasten. Then install the armor pressing part 12 and the traction part 40 in sequence to fix the armor wire 22. After the installation is completed, the anchor 10 and the target submarine cable 20 are pulled to the target platform by the crane. Set the first sub-seat 301 on the target platform, control the crane to pull the anchor 10 and the target submarine cable 20 to move, so that the anchor 10 is set on the clamping step 311 of the first sub-seat 301 to temporarily anchor the target submarine cable 20 and the anchor 10.

[0073] Try to connect the explosion-proof box and the conductor 21. If the currently exposed length of the conductor 21 cannot be connected to the explosion-proof box, control the crane to pull the anchor 10 so that the clamp 11 is separated from the clamping step 311 of the first sub-seat 301. Then, adjust the relative position of the clamp 11 and the target submarine cable 20 so that the clamp 11 is separated from the pressure armor 12. After the adjustment, the clamp 11 is set on the clamping step 311 again to achieve temporary anchoring. Next, process the target submarine cable 20 to expose the conductor 21 of the required length so that the conductor 21 can be connected to the explosion-proof box. After the conductor 21 is connected, adjust the relative position of the pressure armor 12 and the target submarine cable 20 so that the pressure armor 12 and the clamp 11 are fixedly connected. Finally, process the excess armor steel wire 22 and install the second sub-seat 302 to achieve anchoring. When facing multiple target submarine cables 20, the traction member 40 of the previous device can be removed for reuse to save resources.
