Description

Technical Field

[0001] This invention relates to the field of marine technology, and more specifically to a support device and a crane vessel. Background Technology

[0002] According to international conventions and relevant domestic regulations, offshore oil platforms must be dismantled within one year of ceasing production. This dismantling includes the removal of the topside modules. Currently, the dismantling of topside modules typically employs a two-ship method, where two vessels are positioned on either side of the platform. The topside module is lifted and moved from the jacket structure using support devices on the crane vessel, completing the on-site dismantling. A transport vessel then transports the topside module to its destination.

[0003] During disassembly, to accommodate the different air gaps of different platforms, the support device is designed as a multi-layer structure, with each layer connected by welding. However, this support device is not conducive to installation and disassembly. In the prior art, CN214985943U discloses a crane vessel and its support device. In this device, each layer of the structure is connected by pins and blocks to solve the problem of inconvenient installation and disassembly due to welding. However, this method requires high precision in the installation of pin holes, involves a large number of pin holes, and is difficult and costly to install. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a support device and a crane vessel.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A support device, comprising:

[0007] At least two slots, with at least one of the slots located on the main deck of the crane vessel;

[0008] The basic module has a base at its bottom for connecting the card slot and a guide rail connection interface at its top for connecting the guide rail seat.

[0009] At least one standard module has a base at its bottom for connecting to the card slot, and its top is connected to the card slot;

[0010] The base is correspondingly and detachably connected to the slot to realize the connection between the basic module and the standard module, the connection between the standard modules, and the connection between the standard module and the main deck.

[0011] Furthermore, the slot includes an upper slot and a lower slot, and the lower slot includes a positioning element and two limiting elements;

[0012] The two limiting members are located on the same horizontal plane and are parallel to each other. The two limiting members can engage with the base. The positioning member and the limiting member are located on the same horizontal plane and are vertically connected. The positioning member and the limiting member form a U-shaped structure to restrict the movement of the base on the Y-axis.

[0013] Furthermore, the limiting member includes a first limiting member and a second limiting member. The second limiting member is positioned above the first limiting member and aligned with one end of the first limiting member. The length of the second limiting member is greater than that of the first limiting member. The width of the side of the second limiting member facing the center of the slot gradually decreases from the inside to the outside along the extension direction of the second limiting member away from the positioning member.

[0014] Furthermore, the upper groove has a U-shaped structure, is connected to the lower groove and is located above the base, protruding inward relative to the lower groove and used to restrict the movement of the base on the Z-axis.

[0015] Furthermore, the upper groove body has a rounded corner on the side facing the center of the slot, which is used to facilitate the installation and connection of the base and the slot.

[0016] Furthermore, it also includes a pin, and the base is provided with a mounting hole that matches the pin. The pin is fitted into the mounting hole and is used to limit the movement of the base on the X-axis.

[0017] Furthermore, the number of the standard modules is multiple;

[0018] In any two adjacent standard modules, the base of the upper standard module is detachably connected to the slot on the lower standard module.

[0019] Furthermore, the heights of the various standard modules include 1m, 2m, and 4m.

[0020] Furthermore, the connection between the card slot and the standard module and / or between the card slot and the main deck is welding.

[0033] Currently, the dismantling of the superstructure of offshore oil platforms typically employs a dual-ship method. Two vessels are positioned on either side of the platform, and a support device on the crane vessel lifts the superstructure as a whole and moves it away from the jacket, completing the on-site dismantling. During dismantling, to accommodate the different air gaps of different platforms, the support device is designed as a multi-layered structure, with layers connected by welding. However, this support device is inconvenient for installation and dismantling. In the prior art, CN214985943U discloses a crane vessel and its support device. In this device, each layer is connected by pins and blocks to solve the problem of inconvenient installation and dismantling due to welding. However, this method requires high precision in the pin hole installation, involves a large number of pin holes, and is difficult and costly to install.

[0034] To address the aforementioned problems, this invention proposes a support device and a crane vessel.

[0035] The support device includes at least two slots, with at least one slot located on the main deck of the crane vessel; a base module, the bottom of which has a base for connecting to the slots, and a guide rail connection interface on its top for connecting to guide rail seats; and at least one standard module, the bottom of which has a base for connecting to the slots, and its top connected to the slots. The bases and slots are correspondingly arranged and detachably connected to achieve connections between the base module and the standard modules, connections between the standard modules, and connections between the standard modules and the main deck.

[0036] Specifically, the support device includes a base module, at least one standard module, and at least two slots. The base module has a base at its bottom for connecting to the slots, and a guide rail connection interface at its top for connecting to guide rail seats. The standard modules also have bases at their bottoms for connecting to the slots, and their tops connect to the slots. At least one slot is located on the main deck of the crane vessel and connects to the base at the bottom of one of the standard modules. The bases and slots are correspondingly arranged and detachably connected to achieve connections between the base module and the standard modules, connections between the standard modules, and connections between the standard modules and the main deck. Specifically, on two adjacent standard modules, the base at the bottom of the standard module is detachably connected to the slot at the top of the next standard module; between the base module and the standard modules, the base at the bottom of the base module is detachably connected to the slot at the top of the standard module; and between the standard modules and the main deck, the base at the bottom of the standard module is detachably connected to the slot on the main deck.

[0037] Please see Figure 1This is a schematic diagram of the overall structure of a support device according to an embodiment of the present invention. In this embodiment, the support device includes a base module 3, four standard modules 4, and ten slots 1. The slots 1 are disposed on the main deck 2 of the crane vessel and on the top of the standard modules 4. The base 5 is provided at the bottom of both the base module 3 and the standard modules 4. The base 5 at the bottom of the base module 3 is detachably connected to the slot 1 connected to the top of the adjacent standard module 4 below the base module 3. The base 5 at the bottom of the standard module 4 is detachably connected to the slot 1 connected to the top of the adjacent standard module 4 below the standard module 4. The base 5 at the bottom of the lowest standard module 4 is detachably connected to the slot 1 connected to the main deck 2 of the crane vessel.

[0038] The slot includes an upper slot body and a lower slot body. The lower slot body includes a positioning component and two limiting components. The two limiting components are located on the same horizontal plane and are parallel to each other. The two limiting components can engage with the base. The positioning component and the limiting components are located on the same horizontal plane and are vertically connected. The positioning component and the limiting components form a U-shaped structure to restrict the movement of the base on the Y-axis.

[0039] Specifically, the slot includes an upper slot and a lower slot. The lower slot connects to the top of the main deck or standard module of the crane vessel and includes a positioning element and two limiting elements. The two limiting elements are located on the same horizontal plane and parallel to each other, with the distance between them slightly greater than the length of the base, allowing the base to engage. The positioning element and the limiting elements are located on the same horizontal plane and are perpendicularly connected to the limiting elements. The two ends of the positioning element facing the limiting elements are perpendicularly connected to one end of each of the two limiting elements, thus forming a U-shaped structure. When the base engages in the lower slot, this U-shaped structure restricts the movement of the base on the Y-axis and its movement on the X-axis along the direction extending from the limiting elements toward the positioning element.

[0040] Please see Figure 2 This is a schematic diagram of the structure of the lower groove 12 of the slot 1 engaging with the base. The lower groove 12 of the slot 1 includes a positioning member 121 and two limiting members 122. The two limiting members 122 are located on the same horizontal plane and are parallel to each other. The distance between the two limiting members 122 is slightly greater than the length of the base 5, just enough to engage the base 5. The positioning member 121 and the limiting members 122 are located on the same horizontal plane and are perpendicularly connected to the limiting members 122. The two ends of the positioning member 121 facing the limiting members 122 are perpendicularly connected to one end of each of the two limiting members 122. The length of the positioning member 121 is exactly the sum of the length of the base 5 and the width of the two limiting members 122. The positioning member 121 and the two limiting members 122 form a U-shaped structure. When the base 5 is engaged in the lower groove 12, this U-shaped structure can restrict the movement of the base 5 on the Y-axis and the movement on the X-axis along the direction of the limiting members 122 toward the positioning member 121.

[0041] The limiting component includes a first limiting component and a second limiting component. The second limiting component is positioned above the first limiting component and aligned with one end of the first limiting component. The length of the second limiting component is greater than that of the first limiting component. The width of the side of the second limiting component facing the center of the slot gradually decreases from the inside to the outside along the extension direction of the second limiting component away from the positioning component.

[0042] Specifically, the limiting components include a first limiting component and a second limiting component. The first limiting component is used to connect to the top of the main deck or standard module of the crane vessel. The second limiting component is connected to the first limiting component and is positioned above it, with one end of the second limiting component aligned with one end of the first limiting component. The length of the second limiting component is greater than that of the first limiting component, and the width of the side of the second limiting component facing the center of the slot gradually decreases from the inside to the outside along the direction of extension of the second limiting component away from the positioning component. That is, the distance between the open ends of the two parallel second limiting components on the same horizontal plane is greater than the distance between the other parts of the two second limiting components, to facilitate the insertion of the base.

[0043] Please see Figure 3 This is a side view of the lower groove of the card slot. The limiting member 122 is perpendicularly connected to the positioning member 121. The limiting member 122 includes a first limiting member 1221 and a second limiting member 1222, which are connected. The first limiting member 1221 is rectangular in shape. The width of the side of the second limiting member 1222 facing the center of the card slot 1 gradually decreases from the inside to the outside along the extension direction of the second limiting member 1222 away from the positioning member 121. This arrangement ensures that the distance between the open ends of the two parallel second limiting members 122 on the same horizontal plane is greater than the distance between other parts of the two second limiting members 122, facilitating the insertion of the base 5. Let the sum of the widths of the two limiting members and the distance between the two limiting members be a, and the distance between the two limiting members be b, where a > b. In this embodiment, the range within which the base 5 can be inserted is a. If the shape of the second limiting member 1222 is rectangular, then the range within which the base 5 can be inserted is b. Therefore, the shape of the second limiting member is designed to facilitate the insertion of the base 5.

[0044] The upper groove has a U-shaped structure, connecting to the lower groove and located above the base. It protrudes inward relative to the lower groove to restrict the base's movement along the Z-axis. The opening end of the upper groove facing the center of the slot has a rounded corner, which facilitates the installation and connection of the base and the slot.

[0045] Specifically, the upper groove has a U-shaped structure, connecting to and positioned above the lower groove. When the base engages with the slot, the upper groove is located above the base. The upper groove protrudes inward relative to the lower groove, making its internal diameter smaller than the length of the base, thus restricting the base's movement along the Z-axis. Furthermore, the opening end of the upper groove facing the center of the slot has a rounded corner, which facilitates the installation and connection of the base and the slot.

[0046] Please see Figure 4 This is a top view of the slot and base engaging. The base 5 has an I-beam, the length of which is less than the length of the base 5. The upper slot 11 has a U-shaped structure, its outer side aligned with the outer side of the lower slot 12. The upper slot 11 protrudes inward relative to the lower slot 12. The inner diameter of the upper slot 11 is slightly larger than the length of the I-beam but smaller than the length of the base 5, allowing the I-beam to engage. When the base 5 engages with the slot 1, the upper slot 11 is positioned above the base 5 and engages the I-beam. The open end of the upper slot 11 facing the center of the slot 1 has a rounded corner 111, which facilitates the installation and connection between the base 5 and the slot 1. The principle is similar to the shape of the second limiting member. Let the outer length of the upper slot 11 be c, and the inner diameter be d, where c > d. When the rounded corner 111 is provided, the range of the I-beam engaging is c; when the rounded corner 111 is not provided, the range of the I-beam engaging is d. Obviously, setting the arc angle to 111 results in a larger insertion range, making it easier to insert the I-beam.

[0047] The support device also includes a pin, and the base is provided with a mounting hole that matches the pin. The pin is fitted into the mounting hole and is used to limit the movement of the base on the X-axis.

[0048] Please see Figure 2 , Figure 4 and Figure 5 The base 5 has a mounting hole 51 that matches the pin 6. The pin 6 is fitted into the mounting hole 51 and is used to limit the movement of the base 5 along the X-axis. When the base 5 is engaged with the slot 1, the slot 1 has an open structure. Under the action of gravity, the base 5 can still easily slide out from the open structure of the slot 1. Therefore, the pin 6 is provided. When the pin 6 is fitted into the mounting hole 51, the base 5 and the slot 1 are engaged, and even if the base 5 is subjected to gravity, it will not slide out from the open structure of the slot 1, thus limiting the movement of the base 5 along the X-axis.

[0049] There are multiple standard modules. In any two adjacent standard modules, the base of the upper module is detachably connected to the slot on the lower module. The heights of the standard modules include 1m, 2m, and 4m. Please refer to [link / reference]. Figure 1In this embodiment, the support device includes four standard modules 4 with heights of 1m, 2m, 4m, and 4m, respectively. In any two adjacent standard modules 4, the base 5 of the upper standard module 4 is detachably connected to the slot 1 on the lower standard module 4.

[0050] The connection between the card slot and the standard module and / or between the card slot and the main deck is made by welding. Welding provides a more secure connection between the card slot and the standard module, and between the card slot and the main deck.

[0051] In this embodiment, the slots are welded to the top of the standard module and the main deck, respectively, and bases are provided at the bottom of the standard module and the bottom of the base module. The base slides into the slot through the opening structure of the slot to achieve engagement, and the pin is assembled into the mounting hole of the base to achieve fixation. Between two adjacent standard modules, the base located at the bottom of the standard module engages with the slot located at the top of the standard module below and is fixed by the pin; between the base module and the standard module, the base located at the bottom of the base module engages with the slot located at the top of the standard module and is fixed by the pin; between the standard module and the main deck, the base located at the bottom of the standard module engages with the slot located on the main deck and is fixed by the pin.

[0052] In addition, the present invention also proposes a crane vessel having the support device described above.

[0053] In summary, the support device proposed in this invention, by setting slots and pins between each layer of the structure, makes the installation and disassembly of each layer of the structure more convenient, reducing material costs and time costs.

[0054] The above is a detailed description of the preferred embodiments of the present invention. However, the present invention is not limited to the embodiments described.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
