Description

Technical Field

[0001] This invention relates to the field of marine construction and repair technology, and in particular to a berthing structure for an offshore platform wharf. Background Technology

[0002] Marine engineering structures, due to their need to withstand the unique marine environment, have high requirements for structural form and complex and varied design shapes. In addition to the main structure, offshore platforms also include anchors, anchor frames, and other auxiliary components, which are typically designed with an outward-flaring configuration for ease of use. However, this outward-flaring structure is more prone to collisions with nearby objects such as docks. During construction, repair, and maintenance, offshore platforms need to be moored at docks. When affected by tides, wind, waves, and currents, the platform moves vertically, horizontally, and backward, causing the outward-flaring auxiliary components to collide with the dock.

[0003] Chinese Patent CN 202220436787.6 discloses a dock berthing system for floating offshore wind power platforms, including dock berthing facilities with multiple towing devices evenly spaced along the shoreline; a berthing barge is installed between the dock berthing facilities and the wind power platform to form a continuous quay wall. This system is suitable for berthing novel wind power platforms with special structural forms and large tonnage differences at docks with significant water level differences, and can effectively disperse the impact force between the dock and the wind power platform.

[0004] Traditional ship berthing docks use cylindrical floating steel structures and rubber hybrid structures, cylindrical rubber floating pontoons or spherical rubber structures, which are floated between the ship and the dock. Their size is relatively small and the contact area is small, which cannot effectively protect special marine berthing devices. Summary of the Invention

[0005] This invention aims to at least address the technical problem in existing technologies where "existing berthing structures, floating between ships and berths, are too small in size, have a small contact area, and cannot effectively protect special offshore berthing devices." To this end, this invention proposes a berthing structure for offshore platforms that ensures the safety of offshore platform berthing, protects the safe use of berth facilities, is reusable, has low manufacturing costs, and is easy to assemble. The anchor of the offshore platform can be directly disassembled and placed on the barge deck, facilitating its disassembly, assembly, and adjustment.

[0006] According to some embodiments of the present invention, a berthing structure for an offshore platform is provided at the edge of a berth, wherein the berth is provided with bollards, and the offshore platform is fixed to the bollards by cables; comprising:

[0007] A barge is installed between the pier and the offshore platform. The barge is located on the side of the pier to buffer the impact between the offshore platform and the pier. The offshore anchor of the offshore platform is installed inside the barge to prevent the offshore anchor from colliding with the pier.

[0008] The berthing includes a berthing body, a berthing cushion, and inner protective material. The berthing cushion is arranged on the side of the berthing body facing the offshore platform, and the inner protective material is arranged on the side of the berthing body facing the dock.

[0009] The main body of the barge adopts a box-type structure, and the interior is filled with liquid to adjust the buoyancy height of the barge and adjust the height difference between it and the dock.

[0010] According to some embodiments of the present invention, the docking body includes a docking deck, a docking end plate, and a docking bottom plate. The docking deck and the docking bottom plate are arranged in parallel, and the docking end plate is arranged around the docking deck to form a box structure.

[0011] According to some embodiments of the present invention, the docking body is provided with docking side panels and docking wall panels inside, and the docking wall panels and docking side panels are connected in an alternating manner, so that the docking body is divided into multiple water storage chambers.

[0012] According to some embodiments of the present invention, each of the water storage compartments is provided with a docking vent pipe communicating with the outside world, the docking vent pipe extending upward from the surface of the docking deck.

[0013] According to some embodiments of the present invention, internal reinforcing members and internal stiffeners are provided between the plates of the main body of the mooring vessel to improve the structural strength of the mooring vessel's box.

[0014] According to some embodiments of the present invention, the barge deck is provided with barge lifting rings around its perimeter for lifting and transporting the barge.

[0015] According to some embodiments of the present invention, the main body of the backrest is provided with a plurality of backrest ear plates on the side near the backrest cushion. The backrest cushion is connected to the backrest ear plates by a backrest steel wire rope and a shackle. The backrest steel wire rope connects the backrest cushion and the backrest ear plates in series. The shackle is used to adjust the tension of the comb feeding backrest steel wire rope.

[0016] According to some embodiments of the present invention, the mooring pad is made of elastic rubber material and is laid flat on the side of the mooring body close to the offshore platform.

[0017] According to some embodiments of the present invention, the barge deck is symmetrically provided with barge side braces, and the marine anchor frame is erected on the two barge side braces.

[0018] According to some embodiments of the present invention, manholes are provided on both sides of the side support for facilitating water filling operations and personnel access.

[0019] The offshore platform berthing structure according to some embodiments of the present invention has at least the following beneficial effects: the berthing barge adopts a box-type structure, and by injecting liquid into the box to change the height of the berthing barge body, the height difference between the berthing barge and the pier is effectively adjusted, making the connection between the two more stable. The berthing barge pad can reduce the compression load between the offshore platform and the pier, effectively protecting the offshore platform and the pier and preventing damage to both. The offshore anchor is placed on the berthing barge body, which facilitates the disassembly, assembly, and adjustment of the offshore anchor by personnel and prevents the overhanging structural components of the offshore platform from colliding with the pier and causing damage.

[0038] In the description of this invention, unless otherwise explicitly defined, terms such as "setting," "installing," and "connecting" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0039] The following is for reference. Figures 1-8 Describes the berthing structure of an offshore platform wharf according to an embodiment of the present invention.

[0040] like Figures 1-8 As shown, the berthing structure of the offshore platform is mainly set at the edge of the berth 200. Multiple bollards 300 are installed on the berth 200. After the offshore platform 100 is berthed into the berth 200, it is fixed to the bollards 300 by cables 400, thereby defining the position of the offshore platform 100.

[0041] The offshore platform berthing structure of the present invention includes a berthing barge 600 disposed between the berth 200 and the offshore platform 100. Specifically, the berthing barge 600 is disposed on the side of the berth 200 to buffer the impact force between the offshore platform 100 and the berth 200, preventing damage to both due to collision. The offshore anchor 500 of the offshore platform 100 is erected within the berthing barge 600 to prevent damage to the berth 200 due to collision between the offshore anchor 500 and the berth 200.

[0042] A barge 600 buffers the impact between the pier 200 and the offshore platform 100. An offshore anchor 500 floats outside the offshore platform 100, isolated by the barge 600, thus protecting the offshore platform 100 and ensuring it does not collide with the pier 200. The offshore platform 100 floats on the water. During construction, maintenance, and commissioning phases, it needs to be moored at the pier 200. Under the influence of wind, waves, and currents in the water system around the pier 200, excessive swaying in any direction (up, down, left, right, forward, backward) can impact and damage the pier 200, as well as the offshore platform 100's structure. The offshore platform 100 is moored to a bollard 300 on the pier 200 by cables 400, and a floating barge 600 is used between it and the pier 200 to buffer and isolate the offshore platform 100, stabilizing its position and increasing the safety of its construction.

[0043] At least two berth barges 600 should be set up, located at the beginning and end of the offshore platform 100 and the wharf 200 or evenly distributed. When the offshore anchor 500 needs maintenance and commissioning, the berth barges 600 can be set up at the corresponding positions of the offshore anchor 500 to facilitate the construction of the offshore anchor 500.

[0044] The berthing barge 600 includes a berthing body 610, a berthing pad 680, and an inner protective material 690. The berthing pad 680 is positioned on the side of the berthing body 610 facing the offshore platform 100, and the inner protective material 690 is positioned on the side of the berthing body 610 facing the quay 200. The buffer between the berthing body 610 and the quay 200 is achieved through the inner protective material 690, and the buffer between the berthing body 610 and the offshore platform 100 is achieved through the berthing pad 680. Specifically, as... Figure 6 As shown, the inner protective material 690 is welded to the side wall of the berthing body 610. Its structure is a semi-circular tube made of steel pipe. Its function is to increase the inner elasticity of the berthing body 610, effectively protecting it and buffering the impact on the dock 200. The structural height of the inner protective material 690 is 0.8–1.5 m, which increases the contact area with the offshore platform 100 and the dock 200, and can also serve as a protective railing.

[0045] The berthing body 610 adopts a box-type structure, and the interior is filled with liquid to adjust the buoyancy of the berthing barge 600 and the height difference between it and the dock 200. The berthing body 610 is a box-shaped sealed structure that can provide buoyancy in water and float in the water. The berthing body 610 has several sealed compartments inside, which provide buoyancy so that the berthing barge 600 floats in the water.

[0046] In some embodiments of the present invention, such as Figure 5 and Figure 8 As shown, the barge body 610 includes a barge deck 612, a barge end plate 611, and a barge bottom plate 616. The barge deck 612 and the barge bottom plate 616 are arranged in parallel, and the barge end plate 611 is arranged around the barge deck 612 to form a box structure, thereby improving the structural strength of the barge body 610.

[0047] The barge deck 612 is constructed of steel plates, with structural strength meeting the requirements of classification society regulations. The material grade is CCS-A or higher, and its thickness and dimensions can be determined according to specifications. It is capable of withstanding the load of the offshore anchor 500 placed on it during construction. The area of ​​the barge deck 612 is larger than the vertical projection area of ​​the offshore anchor 500, allowing the anchor 500 to be placed on the barge deck 612, effectively protecting the pier 200 and preventing collisions.

[0048] In some embodiments of the present invention, such as Figures 3-8 As shown, the berthing main body 610 is internally equipped with berthing side plates 615 and berthing bulkheads 617. The berthing bulkheads 617 and berthing side plates 615 are staggered, dividing the berthing main body 610 into multiple water storage compartments. Each water storage compartment is independently configured and not interconnected. The buoyancy depth and balance of the berthing barge 600 on the water surface are adjusted by regulating the liquid content within each compartment, thus regulating the height difference between the berthing barge 600 and the dock 200, resulting in a more stable connection. The berthing bulkheads 617 and berthing side plates 615 are composed of steel structural plates and profiles, with structural strength meeting the requirements of classification society specifications. The material grade is CCS-A or higher, and the thickness and dimensions can be determined according to specifications.

[0049] The barge 600 can be adjusted by adding water to each compartment, and its draft can be adjusted to regulate the height difference between the barge 600 and the dock 200. When the barge 600 is placed next to the dock 200, its height is greater than 0, ensuring that the inner protective material 690 of the barge is higher than the dock 200, ensuring that the barge 600 can effectively act on the dock 200 during operations, and will not be submerged in water and lose its effectiveness.

[0050] In some embodiments of the present invention, such as Figure 4 and Figure 5As shown, each water storage compartment is equipped with a docking vent pipe 630 that connects to the outside. The docking vent pipe 630 extends upward from the surface of the docking deck 612. Specifically, the docking deck 612 is designed with docking vent pipes 630, the number of which is determined according to the number of water storage compartments, with one pipe for each compartment. The docking vent pipe 630 is made of steel pipe and extends out of the docking deck 612. The end of the docking vent pipe 630 is U-shaped, so that the outlet of the docking vent pipe 630 faces the surface of the docking deck 612, effectively preventing foreign objects from entering the water storage compartment through the docking vent pipe 630.

[0051] In some embodiments of the present invention, such as Figure 4 and Figure 5 As shown, internal keel 613 and internal reinforcing members 614 are provided between the plates of the barge body 610 to improve the structural strength of the barge 600's box structure. The internal keel 613 and internal reinforcing members 614 are made of steel structural plates and profiles, and their structural strength meets the requirements of classification society specifications. The material grade is CCS-A or higher, and the thickness and size can be determined according to the specifications.

[0052] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the barge deck 612 is equipped with barge lifting rings 620 around its perimeter for lifting and transporting the barge 600. Specifically, the barge deck 612 is designed with four barge lifting rings 620, which are welded to the surface of the barge deck 612. They are made of steel structure material and can be used for the overall lifting and transport of the barge 600, facilitating the adjustment of the position of the barge 600 by the dock crane 200.

[0053] In some embodiments of the present invention, such as Figures 3-5 and Figure 7 As shown, the main body 610 of the docking vessel has multiple docking ear plates 660 on the side near the docking cushion 680. The docking cushion 680 is connected to the docking ear plates 660 via a cushion steel wire rope 672 and a shackle 671. The cushion steel wire rope 672 connects the docking cushion 680 and the docking ear plates 660 in series, and the shackle 671 is used to adjust the tension of the feeding cushion steel wire rope 672. Specifically, the docking cushion 680 is connected to the docking ear plates 660 via the shackle 671 and the cushion steel wire rope 672, serving a suspension and fixing function. The docking ear plates 660 are used to connect anchor points.

[0054] In some embodiments of the present invention, such as Figures 3-7As shown, the berthing pad 680 is made of elastic rubber and is laid flat on the side of the berthing body 610 closest to the offshore platform 100. Specifically, the berthing pad 680 is connected in series by shackles 671 and pad wire ropes 672 to form an integral elastic pad. It can increase the elastic contact with the offshore platform 100, protecting both the offshore platform 100 and the berthing body 610.

[0055] In some embodiments of the present invention, such as Figures 3-5 As shown, symmetrical barge side supports 650 are installed on the barge deck 612, and the marine anchor 500 is mounted on the two barge side supports 650. This facilitates the inspection, maintenance, and disassembly / removal of the marine anchor 500 by personnel. The marine anchor 500 can be placed on the barge side supports 650 of the barge deck 612, and supported by the barge 600, allowing for convenient maintenance, commissioning, and installation of the marine anchor 500.

[0056] In a further embodiment, such as Figures 3-5 As shown, docking manholes 640 are provided on both sides of the docking side support 650 to facilitate water replenishment operations and personnel access. Specifically, one docking manhole 640 is provided above each compartment to facilitate water replenishment operations and personnel access, and the docking manhole 640 is sealed with a manhole cover.
