[0002] As an indispensable important equipment in marine engineering construction, the main function of the offshore installation ship covers the transportation, installation and sinking of large marine components. Such ships can improve the efficiency of offshore operations and ensure the stability and safety of the components during transportation and installation. In particular, in deep-sea oil and gas development, offshore wind farm construction and large-scale projects such as cross-sea bridges, offshore installation ships play a crucial role.

[0003] However, in the prior art, the use of offshore installation ships has certain limitations.

[0044] The utility model will be further described in detail through specific implementation manners combined with the drawings.

[0045] To solve the problem that the construction member is high in cost and difficult to load on a ship, as shown in Figure 1 and Figure 2 The application provides a combined floating installation ship, which comprises a first ship body 1, a second ship body 2 and a supporting structure 3.

[0046] The first ship body 1 and the second ship body 2 are detachably connected to each other, so that the combined floating installation ship has high flexibility during combination and disassembly, and the combination and disassembly of the ship bodies are facilitated. When the first ship body 1 and the second ship body 2 are combined and spliced, they jointly enclose a containing space, and the containing space is used for containing and protecting the floating transportation member 7.

[0047] In order to further enhance the supporting capacity of the transportation member, at least three supporting structures 3 are further arranged. The supporting structures 3 are arranged on the first ship body 1 and the second ship body 2 in the circumferential direction respectively, and the supporting ends of each supporting structure 3 can extend into the containing space to form multi-point support for the transportation member, so that the stability of the member during transportation is improved, the shaking caused by natural factors such as sea waves and wind is effectively reduced, and the transportation safety is further ensured.

[0048] When the modular floating installation vessel of the present application is in operation, the first hull 1 and the second hull 2 ​​are positioned laterally around the component 7 to be transported. After the first hull 1 and the second hull 2 ​​are assembled and spliced ​​together, the main body of the installation vessel is formed. The supporting end of the supporting structure 3 is then supported on the component 7 to be transported, thereby completing the component installation operation onboard. Compared to using lifting equipment, the modular floating installation vessel of the present application is more convenient to operate, and uncontrollable factors such as weather and sea conditions have less impact on the installation process, resulting in higher safety.

[0049] like Figures 3 to 6 As shown, in a specific embodiment of the present application, a flange 4 is provided on one of the first hull 1 and the second hull 2, and a slot 5 is provided on the other of the first hull 1 and the second hull 2. Specifically, when the flange 4 is provided on the first hull 1, the slot 5 is provided on the second hull 2; alternatively, when the flange 4 is provided on the second hull 2, the slot 5 is provided on the first hull 1. When the first hull 1 and the second hull 2 ​​need to be combined and spliced, the flange 4 is simply inserted into the slot 5 to complete the connection. This plug-in connection method is not only simple to operate, but also shortens the time required for installation and disassembly, thereby improving work efficiency.

[0050] like Figures 3 to 6 As shown, in one embodiment of the present application, the modular floating installation vessel further includes a latch structure 6, which is used to enhance the connection stability between the first hull 1 and the second hull 2 ​​and prevent accidental loosening. The latch structure 6 specifically comprises a latch 61, a driver 62, and a pin hole 63 extending through the flange 4 and the slot 5. The driver 62 is mounted on one of the first hull 1 and the second hull 2, and the latch 61 is driven and connected to the driver 62. In actual operation, when the first hull 1 and the second hull 2 ​​need to be assembled and spliced, the flange 4 is first inserted into the slot 5, and the pin hole 63 on the flange 4 is aligned with the pin hole 63 on the slot 5. Subsequently, the driver 62 drives the latch 61 into the pin hole 63 on the flange 4 and the slot 5, thereby achieving a combined locking of the first hull 1 and the second hull 2, effectively preventing the first hull 1 and the second hull 2 ​​from becoming disengaged during navigation. The driver 62 can be a hydraulic / pneumatic cylinder, an electric push rod, or other drive device.

[0051] like Figure 3 and Figure 4 As shown, in a specific embodiment of the present application, the first hull 1 is a straight-line hull. In order to achieve connection with the second hull 2, flanges 4 or slots 5 are provided at both ends of the straight-line hull to facilitate assembly and splicing with the second hull 2.

[0052] In a specific embodiment of the present application, one or more supporting structures 3 are provided on the first hull 1. When only one supporting structure 3 is provided on the first hull 1, the supporting structure 3 is specifically located at the center position of the first hull 1 to cooperate with the supporting structure 3 on the second hull 2 ​​to jointly support the component 7 to be transported.

[0053] like Figure 5 and Figure 6 As shown, in one embodiment of the present application, the second hull 2 ​​is a U-shaped hull. One side of the U-shaped hull has an opening 21, through which the component 7 to be transported is moved to the inside of the U-shaped hull. Slots 5 or flanges 4 are provided on either side of the opening 21 to mate with the flanges 4 or slots 5 at either end of the first hull 1, thereby detachably connecting the first hull 1 to the opening 21 of the second hull 2. The first hull 1 closes the opening 21 of the second hull 2, thereby enclosing the component 7 to be transported within the accommodating space.

[0054] like Figure 7 and Figure 8 As shown, in a specific embodiment of the present application, the support structure 3 includes a bracket 31 and a movable roller assembly 32. The movable roller assembly 32 specifically includes a telescopic member 321 and a roller 322. The bracket 31 serves as the supporting base of the entire support structure 3 and is connected to the first hull 1 or the second hull 2. The fixed end of the telescopic member 321 is connected to the bracket 31, and the roller 322 is rotatably connected to the movable end of the telescopic member 321. The telescopic member 321 can specifically be a hydraulic / pneumatic cylinder, an electric push rod, etc. The roller 322 is driven to extend and retract by the telescopic member 321 so that when it is necessary to support the component to be transported 7, it extends out to form a support with the component to be transported 7. It can also adapt to components to be transported 7 of different sizes and shapes. The axial direction of the roller 322 is arranged at an angle to the telescopic direction of the telescopic member 321 to ensure that the roller 322 can form rolling contact with the component to be transported 7, so that the support structure 3 can dynamically adapt to the ups and downs of the component to be transported 7 floating on the water surface.

[0055] like Figure 7 and Figure 8 As shown, in a specific embodiment of the present application, there are at least two movable roller assemblies 32, and each movable roller assembly 32 is arranged on the bracket 31 at intervals along the vertical direction. By providing multiple movable roller assemblies 32, multi-point support is formed for the transport member 7, which not only improves the overall load-bearing capacity of the support structure 3, but also effectively reduces the load borne by a single movable roller assembly 32, thereby extending the service life of the movable roller assembly 32 and reducing the risk of damage caused by stress concentration.

[0056] The above only describes preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
