Obviously, the described embodiment is a part of the embodiment of the utility model, not all the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the utility model.

[0024] Those skilled in the art will appreciate that, although some embodiments herein include certain features included in other embodiments but not other features, the combination of features of different embodiments is meant to be within the scope of the present invention and form different embodiments. For example, in the claims, any one of the claimed embodiments may be used in any combination.

[0025] Please refer to the attached Figure 1 To Attachment Figure 4 The utility model describes an auxiliary device for mounting and docking an integrated valve.

[0026] At present, the existing FPSO single-point system slip ring stack integrated valve is mainly installed by site crane, which makes it difficult to control the movement trajectory and installation accuracy of the integrated valve. Moreover, when the integrated valve is installed by site crane, the shaking of the integrated valve is easy to cause it to collide with the slip ring stack and the integrated valve interface, resulting in a high risk of collision damage, which requires high professional skills and coordination of the lifting operation commander and operator. Due to the high and complex requirements of the lifting operation, it is difficult to achieve high installation efficiency.

[0027] Therefore, the auxiliary device for installing and docking the integrated valve includes a frame 1, which can be connected to the slip ring stack 12. The frame 1 is provided with a sliding base 4, which can be connected to the integrated valve 13. The sliding base 4 can slide relative to the frame 1. The frame 1 is provided with a first sliding component 2, which is connected to the sliding base 4. The sliding base 4 can be driven by the first sliding component 2 to drive the integrated valve 13 to slide up and down. The first sliding component 2 is provided with a second sliding component 3, which is connected to the sliding base 4. The sliding base 4 can be driven by the second sliding component 3 to drive the integrated valve 13 to slide left and right.

[0028] When installing the integrated valve 13, drive the first sliding assembly 2 to slide the integrated valve 13 upward, and control the height of the integrated valve 13 so that the upper surface height of the integrated valve 13 is lower than the inlet short section of the slip ring stack 12. When the control clearance is lower than 10 mm, the first sliding assembly 2 stops.

[0029] Then, the second sliding assembly 3 is driven to make the integrated valve 13 approach the slip ring stack 12 in the horizontal direction until the deviation between the center of the flange surface above the integrated valve 13 and the inlet center of the slip ring stack 12 is less than 1 mm, and the second sliding assembly 3 stops.

[0030] The first sliding assembly 2 is driven again to control the lifting speed until the gap between the upper surface of the integrated valve 13 and the inlet flange surface of the slip ring stack 12 is less than 2 mm, and then the integrated valve 13 is connected to the slip ring stack 12.

[0031] During the lifting process, it is necessary to monitor the gap between the upper surface of the integrated valve 13 and the inlet short section of the slip ring stack 12, and monitor the deviation between the center of the flange surface above the integrated valve 13 and the inlet center of the slip ring stack 12 to avoid damage to the integrated valve 13 during installation.

[0032] When the gap between the upper surface of the integrated valve 13 and the inlet flange surface of the slip ring stack 12 is less than 2 mm, use bolts to fasten the integrated valve 13 to the slip ring stack 12. By tightening the bolts, make the upper surface of the integrated valve 13 contact the inlet flange surface of the slip ring stack 12. Note that the bolts are tightened in diagonal order. After the upper surface of the integrated valve 13 contacts the inlet flange surface of the slip ring stack 12, initially tighten all bolts according to 50% of the bolt pre-tightening torque, and mark them after the initial tightening is completed. After the initial tightening is completed, re-tighten them, and the re-tightening torque is 100% of the bolt pre-tightening torque. Recheck the bolt torque after 24 hours. At this point, the installation of the integrated valve 13 is completed.

In other embodiments of the utility model, other driving forces can also be used as long as the sliding base 4 can be guaranteed to slide up and down.

[0034] Preferably, the second sliding assembly 3 includes a second hydraulic cylinder 31, the fixed end of the second hydraulic cylinder 31 is fixedly connected to the guide support beam 22, and the output end of the second hydraulic cylinder 31 can drive the sliding base 4 to slide left and right. In other embodiments of the utility model, other driving forces can also be used as long as the sliding base 4 can be guaranteed to slide left and right.

[0035] Furthermore, the sliding base 4 is slidably connected to the guide support beam 22 , and when the output end of the second hydraulic cylinder 31 drives the sliding base 4 to slide, the sliding base 4 slides along the guide support beam 22 .

[0040] When fixing the first flange 41 to the flange of the integrated valve 13, tighten the bolts to make the first flange 41 contact with the flange of the integrated valve 13. Note that the bolts are tightened in diagonal order. After the first flange 41 contacts the flange of the integrated valve 13, all bolts are initially tightened according to 50% of the bolt pre-tightening torque. After the initial tightening, mark them and re-tighten them. The re-tightening torque is 100% of the bolt pre-tightening torque. After 24 hours, the bolt torque is rechecked.
