Jacket and jacket construction method

Abstract

The invention provides a jacket and a jacket construction method. The jacket can be divided into an upper segment and a lower segment for segmented manufacturing. After the two segments are manufactured, the two segments are folded and fixed. In the whole construction process, only butt joint operation of an upper folding opening and a lower folding opening exists in high-altitude operation, the high-altitude operation amount is greatly reduced, and the safety of construction operation is improved. Meanwhile, according to the jacket and the jacket construction method, the turnover operation of the segments is avoided, and the jacket can be positioned in advance according to offshore construction and transportation requirements. In addition, the upper segment and the lower segment of the jacket can be constructed and constructed at the same time, the site occupation of raw materials can be reduced, time can be saved, the project manufacturing period can be shortened, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to the technical fields of marine engineering and electric power engineering, in particular to a jacket and a construction method for the jacket. Background technique [0002] Wind energy is a renewable and clean energy. When other renewable energy sources (such as biomass energy, tidal energy, etc.) are not yet mature, wind energy has become one of the primary choices to alleviate global environmental problems and energy crises. At present, among various foundation types of offshore wind turbines, single pile, jacket, underwater three-pile and above-water three-pile foundation types are the most commonly used types. [0003] Among them, the importance of the jacket as the lower support structure of the offshore booster station is self-evident. At present, conventional jacket construction methods are generally horizontal and vertical. Horizontal construction can reduce the difficulty of on-site construction, especially the diffic...

AI Technical Summary

Problems solved by technology

At present, conventional jacket construction methods are generally horizontal and vertical. Horizontal construction can reduce the difficulty of on-site construction, especially the difficulty of high-altitude operations. However, the requirements for offshore are too high, and the jacket needs to be turned over and erected, making installation difficult. And the risk is too large, there is a big security risk

Due to the high height of the vertical construction, there are a large number of outfitting parts on the top of the jacket, which need to be welded and installed. Due to the limitations of the existing site equipment and other basic conditions, high-altitude operations cannot be carried out
