Description

[0001] The present application is a divisional application of the parent application with the application date of August 28, 2020, the application number of CN202010885603.X, and the name of "A method and device for installing a suction pile jacket of offshore wind power". TECHNICAL FIELD

[0002] The present application relates to the technical field of offshore engineering facilities, in particular to a method and device for installing a suction pile jacket. BACKGROUND

[0003] Offshore wind turbine foundations adopt different forms of foundations such as single pile, skirt pile, gravity type, jacket, and floating type according to water depth. With the development of China's offshore wind power from shallow sea to deep sea, three-pile suction pile jacket wind turbine foundation is widely used due to its advantages of adaptability to 20m-50m water depth, short offshore construction period, and less influence of offshore operation window period. The three-pile suction pile jacket wind turbine foundation includes an upper jacket and three lower suction piles. The overall height of the jacket structure is 92m-98m, and the mass is 2300t-2600t.

[0004] Currently, there are generally two traditional processes for constructing the three-pile suction pile jacket wind turbine foundation, as follows: one is to adopt horizontal construction for the upper jacket, to use lifting equipment for turning over and splicing with the suction pile, and to be equipped with super-large gantry lifting equipment (the lifting capacity needs to be greater than 3000t, and the lifting height needs to be greater than 120m); the other is to adopt horizontal construction in stages for the upper jacket, to be equipped with lifting equipment (the lifting capacity needs to be greater than 1000t, and the lifting height needs to be greater than 120m), and then to be spliced in stages in a vertical manner. The disadvantage of the first method is that the horizontal construction requires the configuration of super-large lifting equipment for overall turning over, and the construction unit needs to invest a lot in equipment. The disadvantage of the second method is that the splicing in stages in a vertical manner is difficult, and the precision requirement for connection is high; the splicing in stages in a vertical manner involves a lot of high-altitude operations, and the safety risk coefficient is high, and the work efficiency is low. It can be seen that the two construction processes either require a large investment in equipment, or the splicing process is difficult and involves a lot of high-altitude operations, which is not conducive to the reduction of construction cost and the improvement of construction efficiency of the three-pile suction pile jacket wind turbine foundation. SUMMARY

[0005] The technical problem to be solved by the present application is to provide a method and device for installing a suction pile jacket of offshore wind power, which solves the problems of large investment in traditional three-pile suction pile jacket construction process and equipment, and difficult splicing process and a lot of high-altitude operations.

[0008] S2, vertically upwardly hoist the first lifting point at a first hoisting speed, vertically upwardly hoist the second lifting point at a second hoisting speed, and simultaneously adjust the horizontal distance between the first lifting point and the second lifting point to gradually decrease until the line connecting the first lifting point and the second lifting point rotates 90° relative to the initial line;

[0009] S3, synchronously vertically upwardly hoist the first lifting point and the second lifting point to a preset installation height at a third hoisting speed, and then install the suction cylinder body vertically below the guide pipe frame body.

[0010] The application further provides a suction cylinder guide pipe frame installation device for connecting the suction cylinder body and the guide pipe frame body, comprising a first lifting tower and a second lifting tower.
