[0019] 1. The integrated superstructure structure of the large floating production storage and offloading vessel is provided with a front and rear position adjustment component. By driving the No. 1 driving handle to rotate, the driving screw can be driven to rotate synchronously. Under the limiting action of the limiting slide, the connecting plate can be moved along the driving screw. During the movement of the connecting plate, the limiting slide can effectively drive the installation block to move synchronously. During the movement of the installation block, the No. 1 side shaft can be used to drive the front guide roller to move synchronously, and the front and rear position of the front guide roller can be adjusted to ensure that the front guide roller can guide the living building during the process of lifting it downward, thereby ensuring the accurate front and rear position of the living building.

[0020] 2. The integrated superstructure structure of the large-scale floating production storage and offloading vessel is provided with a left and right position adjustment component. When the front end of the positioning pin is stuck in the positioning hole, the rotation of the drive shaft can be effectively restricted. When the living building is hoisted and the lower end of the living building moves down between the two side guide rollers, when the positioning pin is removed, the No. 2 drive handle is turned to drive the drive shaft and the gear sleeve to rotate synchronously. By rotating the gear sleeve a certain number of circles, the two driving cross bars can pull the two No. 2 side shafts and the side guide rollers closer to each other through the adjustment block and move them a certain distance quantitatively, so as to adjust the left and right position of the living building so that the left and right position of the living building between the two side guide rollers is accurate, and the staff does not need to adjust it all the time, which saves time and effort and ensures the safety of the staff.

[0021] 3. The integrated superstructure structure of the large floating production storage and offloading vessel, in daily work, adjust the front guide roller and the side guide roller away from the living building, the middle mounting plate, the side mounting plate and the adjustment guide mechanism cooperate with each other, which can effectively play the role of guardrails. When encountering strong winds and waves, adjust the front guide roller and the side guide roller to be close to the living building, and then the front guide roller and the side guide roller can effectively stabilize the living building. The living building is produced through modular technology, which means that the structure, equipment and systems of the living building are decomposed into several relatively independent units with interface relationships according to function or hierarchical system, and then arranged and combined into the whole living building in different ways according to the design and production principles of standardization, generalization, serialization and combination. The modular technology of the living building can complete the installation of outfitting equipment to the greatest extent before the assembly of the total section, improve the construction quality and outfitting rate, and shorten the construction period.

By providing the positioning pin 805 and the positioning hole 105, when the front end of the positioning pin 805 is stuck in the positioning hole 105, the rotation of the drive shaft 801 can be effectively restricted. When the living building 2 is hoisted and the lower end of the living building 2 moves down to between the two side guide rollers 810, when the positioning pin 805 is removed, rotating the No. 2 driving handle 803 can drive the drive shaft 801 and the gear sleeve 802 to rotate synchronously.

[0042] Among them, a limiting protrusion 601 is provided at the middle end of the back side mounting plate 6, and two guide sliding holes 602 are provided on the limiting protrusion 601. A driving cross bar 806 is provided at the upper and lower ends of the gear sleeve 802, and a tooth groove 807 is provided on the driving cross bar 806.

Since the hull guardrail 4 is assembled by docking a plurality of split short guardrails, it can be disassembled and replaced in time when a part is damaged.

[0044] Working principle: when the front end of the positioning pin 805 is stuck in the positioning hole 105, the rotation of the drive shaft 801 can be effectively restricted. When the living building 2 is hoisted and the lower end of the living building 2 moves down to between the two side guide rollers 810, when the positioning pin 805 is removed, the No. 2 driving handle 803 is rotated to drive the drive shaft 801 and the gear sleeve 802 to rotate synchronously. By rotating the gear sleeve 802 a certain number of circles, the two driving cross bars 806 can pull the two No. 2 side shafts 809 and the side guide rollers 810 closer to each other through the adjustment block 808 and move them a certain distance quantitatively, thereby adjusting the left and right positions of the living building 2 so that the living space between the two side guide rollers 810 is close. The left and right positions of the living building 2 are accurate. By driving the No. 1 driving handle 707 to rotate, the driving screw 706 can be driven to rotate synchronously. Under the limiting action of the limiting slide 701, the connecting plate 702 can be moved along the driving screw 706. During the movement of the connecting plate 702, the limiting slide 701 can effectively drive the mounting block 703 to move synchronously. During the movement of the mounting block 703, the No. 1 side shaft 704 can be used to drive the front guide roller 705 to move synchronously, and the front and rear positions of the front guide roller 705 can be adjusted to ensure that during the process of lifting the living building 2 downward, the front guide roller 705 can guide the living building 2, thereby ensuring that the front and rear positions of the living building 2 are accurate.

[0045] Furthermore, when installing the hull guardrail 4, by inserting the horizontal strip of the L-shaped card strip seat 401 into the strip installation groove 101, at this time, the vertical strip of the L-shaped card strip seat 401 is inserted into the inner card groove 102, which can effectively prevent the hull guardrail 4 from shaking, and then the fixing bolts 402 are threadedly connected to the oil storage and unloading hull 1 through the bolt holes 103, further ensuring the stability of the hull guardrail 4. Since the hull guardrail 4 is assembled by docking a plurality of split short guardrails, it can be disassembled and replaced in time when it is damaged somewhere. In daily work, adjust the front guide roller 705 and the side guide roller 810 away from the living building 2, and the middle mounting plate 5, the side mounting plate 6 and the adjustment guide mechanism cooperate with each other, which can effectively play a role. Guardrail function: when encountering strong winds and waves, adjust the front guide roller 705 and the side guide roller 810 to be close to the living building 2, and then the front guide roller 705 and the side guide roller 810 can effectively stabilize the living building 2. The living building 2 is produced through modular technology, which means that the structure, equipment and system of the living building 2 are decomposed into several relatively independent units with interface relationships according to function or hierarchical system, and then arranged and combined into the whole living building 2 in different ways according to the design and production principles of standardization, generalization, serialization and combination. The modular technology of the living building 2 can complete the installation of outfitting equipment to the greatest extent before the assembly of the total section, improve the construction quality and outfitting rate, and shorten the construction period.
