A kind of jacket closing process, support frame and support assembly

Abstract

The embodiment of the invention discloses a jacket closing process, a support frame and a support assembly. The process includes: construction of the support assembly; positioning and placement of the lower section of the jacket; and overall closure of the jacket. The support frame includes at least one placing plate placed on the operating platform, a sliding track arranged on each placing plate, and a plurality of carrying workpieces slidably arranged on the sliding track; and, on the plurality of carrying workpieces Box girder tooling for placing main support pipes is provided. The support assembly includes a support frame, and a power supply unit for pulling and carrying workpieces to slide along the sliding track. It realizes that ordinary docks can also be operated on the spot, avoiding the problem of cost increase caused by dividing independent processing areas, and at the same time, further reduces the difficulty of handling during the adjustment process and improves the handling efficiency.

Description

technical field [0001] The embodiment of the present invention relates to the field of jacket installation and closing, and in particular to a jacket closing process, a support frame and a support assembly. Background technique [0002] The jacket is mainly a basic frame structure used in the fields of offshore oil platforms, offshore lighthouse construction and offshore wind power. Due to its large volume, the overall weight is relatively heavy. During the construction process, its bottom is generally in direct contact with the wharf ground through the main support pipe. However, under the premise of its heavy weight, the bearing capacity of the wharf ground It is often difficult to meet the demand. Therefore, it is often necessary to process it in a fixed processing area during the closing operation and then transport it to the dock. It further adjusts the position, and the hoisting after the overall closing also greatly increases the difficulty of the entire hoisting pro...

AI Technical Summary

Problems solved by technology

Due to its large volume, the overall weight is relatively heavy. During the construction process, its bottom is generally in direct contact with the wharf ground through the main support pipe. However, under the premise of its heavy weight, the bearing capacity of the wharf ground It is often difficult to meet the demand. Therefore, it is often necessary to process it in a fixed processing area during the closing operation and then transport it to the dock. It further adjusts the position, and the hoisting after the overall closing also greatly increases the difficulty of the entire hoisting process, which will cause the problem of high handling costs in the entire process

[0003] In the prior art, for example, CN105019419A discloses a jacket, a jacket foundation platform and a jacket construction method, but it itself is only a simple construction of the jacket structure, and it is difficult for ordinary wharves to meet its construction requirements during the construction process. The demand for conditions and the high cost of handling have not given any relevant explanations

Obviously, in the prior art, construction improvements are often made from the entire structure of the jacket, and even in some cases, by setting transition sections, etc., and these methods are more complex to some extent It makes the whole construction process more complicated
