Problems solved by technology

[0003] However, due to the buoyancy of the lower hull, it presents a mid-arch state, and the upper mouth naturally opens outwards, which is seriously deformed compared with the original structure. During the closing process of the lower hull and the upper hull, the docking accuracy cannot be controlled, and it is not easy to install in place.

Embodiment 1

[0046] see figure 1 and figure 2 , the floating production platform provided in this embodiment includes an upper hull 1 , a lower hull 2 ​​and a docking device 3 . Among them, the upper hull 1 is a truss structure, the lower hull 2 ​​includes an annular buoy 21 and a plurality of columns 22 fixed on the buoy 21. When the upper hull 1 and the lower hull 2 ​​are joined together to form a floating production platform, the upper hull 1 and the The column 22 is connected.

[0047] The buoy 21 floats on the water surface and is the foundation of the entire platform. The interior of the buoy 21 is hollow and can be provided with multiple functional cabins and channels. Looking down, the buoy 21 may be a circular shape, a zigzag shape, etc. In this embodiment, the buoy 21 is a square, and the four sides of the buoy 21 are of equal width. When a plurality of uprights 22 are arranged on the buoy 21, they are arranged at intervals along the edge direction of the buoy 21, and the num...

Embodiment 2

[0066] see Figure 4 , Image 6 and Figure 7 , the second embodiment of the present disclosure provides a method for adjusting the folding precision, which includes the following steps:

[0067] S1. Move the lower hull 2 ​​to the water surface below the upper hull 1 to make the orientation of the lower hull 2 ​​and the upper hull 1 consistent, and adjust the deformation of the lower hull 2 ​​by adjusting the filling amount of the medium in the ballast tank 23 on the lower hull 2 To the allowable range of deviation, complete the preliminary alignment of the lower hull 2 ​​and the upper hull 1;

[0068] S2. Gradually lower the upper hull 1, and complete the closing through the docking device 3.

[0069] It should be noted that, in the above step S1, after the upper hull 1 is launched, the barge can be towed to the bottom of the crane 4 in the dock, and the upper hull 1 is lifted into the air by the crane 4, and the lifting height should be at least higher than that after the...

Abstract

The invention discloses a docking device and a folding precision adjusting method. The docking device is used for docking and closing an upper ship body and a lower ship body of the floating production platform, and comprises a guide cone fixed to the top end of a stand column of the lower ship body, and the guide cone is gradually thickened in the direction from top to bottom; the sleeve is fixed to the bottom end of the upper ship body, the sleeve is arranged on the periphery of the guide cone in a sleeving mode, and the inner periphery of the sleeve abuts against the outer circumferential face of the guide cone. The docking device is arranged, after preliminary alignment of the upper ship body and the lower ship body is completed, in the process that a sleeve in the docking device descends along the peripheral face of a guide cone, due to the fact that the guide cone is gradually thickened from top to bottom, the sleeve exerts horizontal force on the guide cone, and extension deformation of the lower ship body is gradually pressed back to the design state; and then accurate folding of the lower ship body and the upper ship body is smoothly completed, and the lower ship body and the upper ship body are installed in place.

Description

technical field [0001] The application belongs to the technical field of offshore platforms, and in particular relates to a docking device and a method for adjusting the closing precision. Background technique [0002] Floating production platforms can be used for offshore oil storage, crude oil processing and other operations, and are important equipment for deep-water development. The floating production platform is generally composed of an upper hull and a lower hull. According to the current construction technology and hoisting equipment, the upper hull can be hoisted, and then placed on the floating lower hull for closing. [0003] However, due to the effect of buoyancy on the lower hull, it is in a middle-arch state, and the upper opening naturally opens outward, which is seriously deformed compared with the original structure. During the process of closing the lower hull with the upper hull, the docking accuracy cannot be controlled, and it is not easy to install in p...
