[0060] A plurality of lifting ears 1114 are provided on the top of the frame body 111. A lifting hole is provided on the lifting ears 1114. Specifically, the lifting ears 1114 are provided on the top of the support column 1111. In this embodiment, each support column 1111 is provided with a lifting ear 1114. The alignment tool 1 is lifted by the lifting ears 1114.

[0061] The adjusting member 13 is used to adjust the lower hull. Figure 3 In this embodiment, the number of the adjusting members 13 is two. In other embodiments, the number of the adjusting members 13 can also be three or other numbers, which are specifically set according to actual needs.

[0062] The adjusting member 13 includes a fixed end and a telescopic end 131. The telescopic end 131 is used to abut against the outer periphery of the lower hull, and the telescopic end 131 can move along the second direction relative to the fixed end, thereby adjusting the lower hull.

[0063] That is, the lower hull is moved by extending the telescopic end 131, thereby adjusting the position of the lower hull so that the center line of the lower hull can be aligned with the center line of the upper hull.

[0064] Figure 4 FIG. 2 shows a cross-sectional view of another embodiment of the alignment tool 1 along the AA direction, Figure 5 A cross-sectional view along the BB direction of another embodiment of the alignment tool 1 is shown, combined with Figure 4 and Figure 5The alignment tool 1 further includes a moving member 14. At this time, the working platform 12 extends outwardly from the support frame at the telescopic end 131 along the second direction. The moving member 14 can abut against the telescopic end 131 of the adjusting member 13 and move along with the movement of the telescopic end 131. That is, the two ends of the moving member 14 along the second direction abut against the telescopic end 131 and the outer periphery of the lower hull, respectively, and the telescopic end 131 is telescoped to adjust the lower hull.

[0065] A flexible protective layer 144 is provided on one side of the moving member 14 away from the telescopic end 131 to avoid damaging the lower hull when the moving member 14 abuts against the lower hull. For example, the protective layer 144 can be rubber.

[0066] Preferably, the protective layer 144 has a thickness of 30-60 mm, which refers to the dimension along the second direction.

[0067] By disposing the moving member 14, the interval between the outer periphery of the lower hull and the supporting frame is increased, thereby avoiding interference with some structural members on the lower hull.

[0068] Specifically, the moving member 14 includes an abutting portion 141, a transition portion 142 fixed to the bottom of the abutting portion 141, and a rolling portion 143 rotatably connected to the transition portion 142. The rolling portion 143 can roll on the working platform 12 to drive the abutting portion 141 to move.

[0069] Figure 6 A schematic diagram of the structure of the abutment is shown, see Figure 6 In this embodiment, the abutting portion 141 includes an upper wing plate 1411 and a lower wing plate 1412 which are arranged in parallel and spaced apart, and a web 1413 connecting the upper wing plate 1411 and the lower wing plate 1412.

Figure 7 Shows Figure 6 Cross-sectional view along CC direction, see Figure 7 The limiting member includes two limiting plates 15 spaced apart on the working platform 12. The two limiting plates 15 together enclose a receiving space and a limiting space. The limiting space is located above the receiving space and communicates with the receiving space. The receiving space is used to receive the lower wing plate 1412, the transition portion 142 and the rolling portion 143. The limiting space is used to receive the belly plate 1413. The limiting space limits the lower wing plate 1412 from moving upward.

[0071] In this embodiment, the limiting plate 15 includes a side plate 151 and a top plate 152 fixed to the inner side of the side plate 151. The inside and the outside are based on the use state of the limiting member, and the space defined by the two limiting plates 15 is the inside, and the opposite is the outside.

[0072] There is a gap between the two side plates 151 to form a receiving space. There is a gap between the two top plates 152 to form a limiting space.

[0073] That is, when the moving member 14 moves, the abutting portion 141 is limited by the limiting member, so that the moving member 14 can not only move along the second direction but also ensure that the moving member 14 does not drift upward when moving.

[0074] Figure 8 A cross-sectional view of another embodiment of the alignment tool 1 along the AA direction is shown.

[0077] The bottom of the escalator 113 is located above the bottom of the frame body 111. Specifically, the height difference between the bottom of the escalator 113 and the bottom of the frame body 111 is not less than 80m. In other embodiments, the height difference between the bottom of the escalator 113 and the bottom of the frame body 111 can also be other values, which are specifically set according to actual needs.

[0078] A plurality of fixing rods are further provided between the escalator 113 and the frame body 111 to strengthen the connection between the escalator 113 and the frame body 111 .

[0079] A flange is also provided at the bottom of the support frame. A plurality of through holes are provided at intervals along the circumferential direction on the flange. The entire alignment tool 1 can be detachably installed through the flange, so that the alignment tool 1 can be installed through a detachable connection during use, and can be disassembled and recycled after use, thereby realizing the reuse of the alignment tool 1.

[0080] Specifically, the flange member includes a plurality of first flange plates 161, and the plurality of first flange plates 161 are arranged in one-to-one correspondence with the plurality of support columns 1111, that is, a first flange plate 161 is arranged at the bottom of each support column 1111. The first flange plate 161 extends outward beyond the corresponding support column 1111, and a plurality of first connection holes are arranged at intervals along the circumferential direction on the first flange plate 161, and the plurality of first connection holes are located at the outer periphery of the corresponding support column 1111.

The connection is achieved by fasteners penetrating the second connection holes and other structures such as through holes on the base surface.

[0082] In other embodiments, the flange member can also be an integral flange plate. The flange plate is located at the bottom of the support frame and extends outwardly beyond the support frame. A connecting hole is provided in the area of ​​the flange plate that extends beyond the support frame.

[0083] Exemplarily, the use of the alignment tool 1 is introduced by bringing the upper hull and the lower hull of a semi-submersible production platform together and adjusting the lower hull with the alignment tool 1.

[0084] Among them, when positioning, the alignment tool 1 is positioned based on the center line of the semi-submersible production platform to ensure the accuracy of positioning.

[0085] The specific steps include:

[0086] S1. Preparation stage.

[0087] S11. Prefabricate the alignment tool 1 according to the data of the lower hull.

[0088] Specifically, the height of the alignment tool 1 is determined according to the data of the lower hull.

[0089] When prefabricating the alignment tool 1, it is also necessary to ensure that its accuracy and structural strength meet the design requirements, that is, to ensure that the alignment tool 1 meets the requirements of serving as the positioning basis for the lower hull.

[0090] S12. Set up strengthening structures in the working area.

[0091] Specifically, the working area refers to the dock where the upper hull and the lower hull are closed.

[0092] In this embodiment, the reinforcement structure is a cement foundation 2 containing embedded iron. The support frame is arranged on the cement foundation 2. In other embodiments, other reinforcement treatments may also be adopted.

[0093] S13, installing the alignment tool 1 in the working area.

[0094] In this embodiment, the number of alignment tools 1 is four. Two are arranged at intervals in the longitudinal direction of the dock, and two are arranged at intervals in the transverse direction of the dock. For example, both the east and west sides extend longitudinally, and both the north and south sides extend transversely. Two alignment tools 1 are arranged at intervals on the east side, and two alignment tools 1 are arranged on the north side.

[0095] S2: The stage of upper hull and lower hull being assembled.

[0096] S21. The upper hull is docked in advance, the hook is completed, and the upper hull is hoisted.

[0097] S22: The lower hull is wet-towed and floated into the dock to complete the mooring.

[0098] Specifically, after the lower hull is docked, the dock door is closed to reduce the impact of the tide on the closing of the hull.

[0099] S23, using the winch cable, the lower hull is brought close to the alignment tooling 1 to complete the rough positioning of the lower hull.

[0100] Specifically, the lower hull can be firstly close to the two pairs of tooling 1 on the west side, and then close to the two pairs of tooling 1 on the north side.

[0101] In other embodiments, the lower hull may first be close to the two counter-position toolings 1 on the north side, and then close to the two counter-position toolings 1 on the west side.

[0102] S24. Use a total station to measure the reference points marked in advance on the upper hull and the lower hull to confirm the accuracy deviation of the joint between the upper hull and the lower hull.

[0103] S25. According to the above-mentioned precision deviation, the lower hull is adjusted by the alignment tool 1.

[0104] During adjustment, if the lower hull has a deviation value toward the west, the adjustment member 13 of the alignment tool 1 on the west side is used to extend the deviation value toward the east. If the lower hull has a deviation value toward the east, the alignment tool 1 on the west side is adjusted to a suitable position, and then the lower hull is brought close to the alignment tool 1 on the west side by the cable.

[0105] For example, if the lower hull deviates 50mm to the west, the alignment tool 1 on the west side is adjusted 50mm to the east. If the lower hull deviates 50mm to the east, the alignment tool 1 on the west side is adjusted to a suitable position, and then the lower hull is brought close to the alignment tool 1 on the west side by the cable to achieve precision adjustment.

[0106] In addition, the north-south adjustment of the lower hull is similar to the above.

[0107] Preferably, the minimum deviation of the lower hull is controlled within ±50 mm.

[0108] S26, the lower hull POST point effectively enters the guide, and then the effect of the adjusting member 13 of the alignment tool 1 on the lower hull is released.

[0109] S27, lowering the upper hull, and during the lowering process, monitoring the accuracy of the upper and lower closing openings in real time, and adjusting the lower hull in real time to align the center lines of the upper hull and the lower hull.

[0110] Specifically, the upper hull is in guiding contact with the lower hull, and the accuracy of the lower hull is adjusted in real time to ensure that the center line of the upper hull is aligned with the center line of the lower hull.

[0111] S28. The upper hull is completely lowered onto the lower hull. After all the closing openings are assembled, the connection between the crane and the upper hull is released to complete the closing of the upper hull and the lower hull.

[0112] That is, the alignment tool 1 can not only realize rough positioning, but also realize precise positioning. For details, see step S23 and step S25. The adjustment process of the alignment tool 1 for both rough positioning and precise positioning is relatively simple.

[0113] The alignment tool in this embodiment has the following advantages:

[0114] The alignment tooling abuts against the outer periphery of the lower hull through the telescopic end of the adjusting member, and adjusts the position of the lower hull by extending the telescopic end outward, thereby aligning the center line of the lower hull with the upper hull. Since the adjusting member is used, the positioning deviation caused by the tensioning of the cable when using the cable is avoided, and the alignment tooling improves the alignment accuracy when closing the upper hull and the lower hull. The alignment tooling is simple to operate, thereby improving the efficiency of closing the upper hull and the lower hull.
