Construction method for building large-scale offshore wind farm with depth more than 2m

Abstract

The invention relates to a construction method for building a large-scale offshore wind farm with depth more than 2m, which mainly comprises the following steps: dragging a construction ship to the set position by a shoal water tug boat, starting a lifting device on the construction ship after the construction ship is positioned to lift the ship body from the water level by 2-3 m; dragging a vehicle pontoon provided with devices such as a steel pipe pile, a blower operating platform, a tower cylinder, a blower bin, a hub, blades and the like near the construction ship through the shoal water tug boat and then anchoring and positioning; and then constructing by utilizing devices such as a 400-t fully-revolving crane and the like on the construction ship. The invention leads the construction ship to perform the construction on the large-scale offshore wind farm with depth equal to or more than 2m because operation, loading and dragging are separated, has the advantages of continuous operation without being influenced by tide, convenient construction, high speed, high efficiency, low construction cost, and the like, and fills up the blank of constructing and building the large-scale offshore wind farm at the zone of 2-5 m in the world.

Description

technical field [0001] The invention relates to a construction method for building a large offshore wind farm, in particular to a construction method for building a large offshore wind farm in an offshore area with a water depth greater than 2 meters. Background technique [0002] Wind energy is a clean and renewable energy. Wind power generation has been paid more and more attention. The establishment of large-scale wind farms is also an important way to solve my country's energy shortage. Offshore wind energy also has the advantages of not occupying land resources, being far away from people, and causing little interference to social life. For coastal areas with rich wind resources, it is planned to build large-scale offshore wind farms. At present, the world's Shanghai wind power infrastructure is mainly divided into the following three types: [0003] Single pile or multi-pile foundation: It is the most widely used type in shallow sea areas. This kind of pile foundation ...

Problems solved by technology

Taking the tidal flats along the coast of the Yellow Sea in the southeast of Jiangsu Province as an example, this area is different from other wind power installation sites. It is impossible to work in this area: small and medium-sized crane ships cannot meet the requirements for high lifting and heavy lifting. Entering this area for construction will seriously affect the development of my country's offshore wind power industry
