Description

Technical Field

[0001] This invention relates to the field of marine engineering technology, specifically to a marine platform transportation device. Background Technology

[0002] Offshore platforms are structures that provide production and living facilities for activities such as drilling, oil production, cargo collection, observation, navigation, and construction at sea. The continuous development of marine engineering and the increasing depth of operations have led to the increasing size of offshore platform structures such as jackets and modules.

[0003] Traditional lifting and transportation methods are unsuitable for transporting such structures. Currently, the mainstream transportation method is the skid-slip method for loading and launching large offshore platforms. The offshore platform structure is transported to the installation location by towing the ship; after the offshore platform structure is skid-slipped onto the ship, it is secured with various clamps; when the offshore platform structure needs to be detached from the ship, all the clamps need to be disassembled, making the loading and unloading of offshore platform structures quite troublesome. Summary of the Invention

[0004] The purpose of this invention is to provide a marine platform transportation device to solve the problems in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A marine platform transport device includes a transport hull and a support assembly. Ballast tanks are installed on the outer wall and inside the transport hull to regulate the diving depth of the transport hull. The forward end of the transport hull has a towing rope and a clamping winch, one end of which is connected to a towing vessel. The clamping winch has two clamping ropes wound on it. The stern of the transport hull has a stern clamp, the middle of which is rotatably mounted on the side wall of the transport hull. The upper end of the stern clamp extends to the upper side of the stern of the transport hull, and the lower end of the stern clamp has a floating element. The ends of the two clamping ropes away from the clamping winch are connected to the stern clamp. The support assembly includes a bracket and at least one slide rail. The bottom of the bracket is fixed to the transport hull, and the end of the bracket near the bow of the transport hull has a forward protective plate. The slide rail is arranged along the length of the bracket, and the marine platform structure is slidably fastened to the slide rail.

[0007] Based on the above technical solutions, the present invention also provides the following optional technical solutions:

[0008] In one alternative embodiment: the tail clamp includes two rotating seats connected by a connecting rod shaft, which is rotatably mounted at the stern of the transport vessel hull, and the two rotating seats are located on both sides of the transport vessel hull; the rotating seats have floating support arms and protective support arms, the floating element is mounted at the end of the floating support arm, a protective roller is provided between the two protective support arms, and the two protective support arms are also connected to the ends of corresponding clamping ropes.

[0009] In one alternative: each ballast tank has an air inlet at the top connected to the outside, and a water inlet / outlet at the bottom connected to the outside.

[0010] In one alternative: the outer sidewall of the transport vessel is provided with protective strips distributed circumferentially, and the protective strips are made of rubber material.

[0011] In one alternative: the support assembly further includes multiple side guards arranged in two rows on both sides of the bracket; each side guard includes a longitudinal shaft and a protective wheel, the longitudinal shaft is rotatably mounted on the bracket and has a spring between the longitudinal shaft and the bracket; the protective wheel is fixed on the longitudinal shaft and has multiple protrusions on its outer wall.

[0012] In one alternative embodiment: the side guard also includes a guide pulley, which is fixed on a longitudinal rotating shaft. The clamping rope passes around the guide pulley, and the guard wheel has an eccentric wheel structure. When the clamping rope pulls the tail clamping device to the tail of the offshore platform structure, the clamping rope can drive the longitudinal rotating shaft to rotate through the friction between it and the guide pulley, thereby causing the guard wheel to rotate.

[0013] In one alternative: the support assembly is fixedly connected to the transport vessel hull at its four bottom corners via fulcrums, forming an adjustment gap between the support assembly and the transport vessel hull. Multiple tilting adjustment components are fixed to the bottom of the support assembly within the adjustment gap. Each tilting adjustment component includes a horizontal guide rail and multiple adjusting slides. The horizontal guide rail is fixed to the bottom of the support assembly, with both ends located on opposite sides of the transport vessel hull. The ends of the horizontal guide rail have baffles. Multiple adjusting slides are slidably mounted on the horizontal guide rail, and each adjusting slide has an adjusting float.

[0014] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0015] 1. In this invention, the transport hull can be embedded underwater, thereby reducing the impact of wind and waves on the marine platform structure. The marine platform structure can float on the sea surface when the transport hull is submerged. By towing the transport hull, the marine platform structure can be automatically separated.

[0016] 2. In this invention, the tail clamp can be used to clamp the tail of the marine platform structure by the traction of the clamping rope, ensuring the stability of the marine platform structure during transportation. When the marine platform structure is loaded or unloaded, it will automatically rotate to a horizontal state by the buoyancy of the floating parts, thus facilitating the loading or unloading of the marine platform structure.

[0017] 3. The invention has a simple structure. The marine platform structure can automatically detach as the transport vessel submerges, which is convenient for unloading. The marine platform structure is in a clamped state during transportation, which ensures transportation stability and has strong practicality. Attached Figure Description

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. In the drawings or description, similar or identical parts are referred to by the same reference numerals, and in practical applications, the shape, thickness, or height of each component may be enlarged or reduced. The embodiments listed in this invention are merely illustrative and not intended to limit the scope of the invention. Any obvious modifications or changes made to this invention do not depart from the spirit and scope of the invention.

[0024] In one embodiment, such as Figures 1-3As shown, a marine platform transportation device includes a transport hull 1 and a support assembly 4. Ballast tanks 11 are installed on both the outer wall and interior of the transport hull 1, and the ballast tanks 11 are used to adjust the diving depth of the transport hull 1. The forward end of the transport hull 1 has a towing rope 3 and a clamping winch 5, one end of which is connected to a towing vessel. The clamping winch 5 has two clamping ropes 8 wound on it. The stern of the transport hull 1 is provided with a stern clamp 9, and the stern clamp 9 is rotatably mounted on the side wall of the transport hull 1. The upper end of the stern clamp 9 extends to the upper side of the stern of the transport vessel hull 1, and the lower end of the stern clamp 9 has a floating element 10; the ends of the two clamping ropes 8 away from the clamping winding winch 5 are both connected to the stern clamp 9; the support assembly 4 includes a bracket 41 and at least one slide rail 43, the bottom of the bracket 41 is fixed to the transport vessel hull 1 and the end of the bracket 41 near the bow of the transport vessel hull 1 has a front protective plate 42, the slide rail 43 is arranged along the length of the bracket 41 and the offshore platform structure 2 is slidably fastened to the slide rail 43.

[0025] In this embodiment, when the marine platform structure 2 is installed on the support assembly 4, the top of the stern clamp 9 rotates to the stern of the transport hull 1 and remains horizontal. The marine platform structure 2 is pushed onto the bracket 41 by the stern of the transport hull 1, and the bottom of the marine platform structure 2 slides into the slide rail 43. The end of the clamping rope 8 is detached from the stern clamp 9 and connected to the front of the marine platform structure 2. The marine platform structure 2 can be pulled onto the support assembly 4 by the winding of the clamping winch 5. After the marine platform structure 2 is on the support assembly 4, the front protective plate 42, located at the front end of the transport hull 1, prevents the marine platform structure 2 from detaching from the support assembly 4. The end of the clamping rope 8 is reconnected to the clamping rope 8, and the stern clamp 9 rotates to above the stern of the transport hull 1 by the traction and pulling of the clamping winch 5, thus... The clamping fastener 9 prevents the offshore platform structure 2 from detaching from the support assembly 4 at the stern of the transport vessel 1. Ballast tank 11 adjusts the transport vessel 1 to a semi-submerged state on the sea surface, effectively avoiding the influence of sea winds and ensuring the stability of the offshore platform structure 2 on the transport vessel 1. After the tugboat pulls the transport vessel 1 and the offshore platform structure 2 to a suitable position on the sea surface, the clamping winch 5 loosens the clamping rope 8, and the buoyancy of the transport vessel 1 is adjusted through the ballast tank 11 to submerge the transport vessel 1 below the sea surface, while the offshore platform structure 2 floats on the sea surface. Under the action of buoyancy, the floating component 10 causes the stern clamping fastener 9 to flip to the stern of the transport vessel 1 and be in a horizontal state. Then, the tugboat pulls the transport vessel 1, allowing the offshore platform structure 2 to automatically detach from the stern of the support assembly 4. This enables rapid sliding loading and unloading of the offshore platform structure 2, shortening the loading period and reducing construction costs.

[0026] In one embodiment, such as Figure 1 and Figure 3 As shown, the tail clamp 9 includes two rotating seats 91 connected by a connecting rod shaft 96. The connecting rod shaft 96 is rotatably mounted at the stern of the transport hull 1, and the two rotating seats 91 are located on both sides of the transport hull 1. Each rotating seat 91 has a floating support arm 92 and a protective support arm 93. A floating component 10 is installed at the end of the floating support arm 92, and a protective roller 95 is located between the two protective supports 93. The two protective supports 93 are also connected to the ends of corresponding clamping ropes 8. In this embodiment, the traction of the clamping ropes 8 allows the protective supports 93 to rotate to the stern of the marine platform structure 2, and the protective rollers 95 abut against the side wall of the marine platform structure 2. Thus, the protective rollers 95 can cooperate with the front protective plate 42 to clamp the front and rear parts of the marine platform structure 2. When the clamping ropes 8 are slack and the transport hull 1 submerges, the buoyancy of the floating component 10 can be used to rotate the rotating seats 91, and the protective supports 93 can be in a horizontal state, facilitating the automatic separation of the marine platform structure 2.

[0027] In one embodiment, such as Figure 1 As shown, each ballast tank 11 has an air inlet at the top connected to the outside, and a water inlet / outlet at the bottom connected to the outside. In this embodiment, the weight of the ballast tank 11 and the weight of the entire transport vessel 1 can be adjusted by the water inlet / outlet, thereby allowing the transport vessel 1 to submerge. The air inlet can be used to adjust the airflow inside the ballast tank 11, and the buoyancy of the ballast tank 11 can be adjusted by adjusting the water volume and air flow inside the ballast tank 11.

[0028] In one embodiment, such as Figure 1 As shown, protective strips 12 are distributed circumferentially on the outer side wall of the transport hull 1. The protective strips 12 are made of rubber material. In this embodiment, the protective strips 12 can reduce the collision between the transport hull 1 and the seabed reef.

[0029] In one embodiment, such as Figure 1 and Figure 2As shown, the support assembly 4 also includes multiple side protection members 44, which are arranged in two rows on both sides of the bracket 41. Each side protection member 44 includes a longitudinal rotating shaft 441 and a protective wheel 443. The longitudinal rotating shaft 441 is rotatably mounted on the bracket 41 and has a spring between it and the bracket 41. The protective wheel 443 is fixed to the longitudinal rotating shaft 441 and has multiple protrusions on its outer wall. In this embodiment, the side protection members 44 can provide a certain degree of protection for the offshore platform structure 2 from the side, and the longitudinal rotating shaft 441 and the protective wheel 443 can rotate. This will not affect the loading and unloading of the offshore platform structure 2. The side protection component 44 also includes a guide pulley 442, which is fixed on the longitudinal rotating shaft 441. The clamping rope 8 passes around the guide pulley 442, and the protective wheel 443 has an eccentric wheel structure. When the clamping rope 8 pulls the tail clamping device 9 to the tail of the offshore platform structure 2, the clamping rope 8 can drive the longitudinal rotating shaft 441 to rotate through the friction between it and the guide pulley 442, and cause the protective wheel 443 to rotate. As a result, the side wall of the protective wheel 443 can abut against the side wall of the offshore platform structure 2, increasing the protection strength.

[0030] In one embodiment, such as Figure 1 and Figure 4 As shown, the support assembly 4 is fixedly connected to the transport hull 1 at its four bottom corners via fulcrum 13, forming an adjustment gap between the support assembly 4 and the transport hull 1. Multiple tilting adjustment components 6 are fixed to the bottom of the support assembly 4 within this adjustment gap. Each tilting adjustment component 6 includes a horizontal guide rail 61 and multiple adjusting slides 63. The horizontal guide rail 61 is fixed to the bottom of the support assembly 4, with both ends of the horizontal guide rail 61 located on opposite sides of the transport hull 1. The ends of the horizontal guide rail 61 have baffles 62. Multiple adjusting slides 63 are slidably mounted on the horizontal guide rail 61, and each adjusting slide 63 has an adjusting buoy 64. When the transport hull 1 tilts due to wind and waves, the horizontal guide rail 61 tilts, and the adjusting slides 63 automatically slide down onto the lower side of the transport hull 1. This allows the adjusting buoy 64 to be positioned on the lower side, and by adjusting the buoyancy of the adjusting buoy 64 on the sea surface, the risk of the transport hull 1 capsizing can be reduced.

[0031] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
