A method of constructing an offshore wind power jacket

Abstract

The invention discloses a construction method of an offshore wind power jacket, which includes the following steps: making the first component and the second component respectively lean against the first template for positioning, and fixing the first connecting piece to the first component and the second component. A top frame is formed between the two components; the third component and the fourth component are respectively positioned against the second template part, and the second connecting piece is fixed between the third component and the fourth component to form a bottom frame; Move the top frame to the top of the bottom frame, and fix the top frame on the bottom frame to assemble into a jacket. The top frame and the bottom frame are upright, and the production accuracy of the top frame and the bottom frame is guaranteed. The top frame and the bottom frame can be independently manufactured, which greatly improves the production efficiency. The top frame can be directly moved to the top of the bottom frame for fixing , no need to turn over and erect, reduce the amount of work at heights, and have high safety.

Description

technical field [0001] The invention relates to the technical field of offshore wind power equipment construction, in particular to a construction method of an offshore wind power jacket. Background technique [0002] In recent years, as a clean energy technology, wind power generation has been gradually recognized by people to play a prominent role in reducing environmental pollution, adjusting the energy structure in the power grid, and solving the problem of electricity consumption for residents in remote areas. In terms of commercialization, people began to pay attention to the development of wind power generation. [0003] As a kind of offshore wind power basic equipment with light weight, good adaptability to seabed geological conditions, good stability, and suitable for deep sea areas, jacket basic equipment has been widely used in offshore wind farms. The jacket is connected between the underwater pile foundation of the offshore wind turbine tower and the upper towe...

Problems solved by technology

[0004] At present, there are two assembly methods for conventional offshore wind power jackets. One is to assemble the jacket horizontally in the factory to reduce the difficulty of high-altitude assembly construction, and then directly ship horizontally to the offshore wind power installation location. Use two large floating cranes to lift the jacket and turn it upright, and insert it vertically into the underwater steel pipe pile. This method needs to be equipped with two large floating cranes for lifting at the installation site, which is costly and expensive. The risk of turning over and erecting large steel components at sea is relatively high, and there are great potential safety hazards; the other is to assemble the jacket horizontally in the factory to reduce the difficulty of high-altitude assembly construction. After the assembly is completed, use two large lifting equipment Turn it over and erect it, ship it upright and transport it to the installation location of the offshore wind power. At the installation location, use a large floating crane to lift and install it. This method requires the use of two large cranes in the factory to turn it over and erect it. Production and Shipping costs are also higher
