Embodiment Construction

[0025] Referring to the accompanying drawings, the construction method of the present invention for large-scale offshore wind farm construction in areas where the water depth is greater than 2 meters mainly includes the following steps:

[0026] A) Use the shallow water tugboat to tow the construction ship to the set position. After the construction ship is positioned, the shallow water tugboat can leave;

[0027] B) start the hoisting device 3 on the construction ship, so that the hull 1 rises to 2-3 meters above the water surface, and now the construction ship obtains a solid foundation, and the hull is not affected by currents and waves;

[0028] C) The shallow water tugboat tows the transport barge equipped with steel pipe piles, wind turbine operating platform, tower, wind turbine cabin, hub, blades and other equipment to the vicinity of the construction ship and anchors for positioning;

[0029] D) The main hoist of the 400-ton full-slewing crane 2 on the construction sh...

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 ...
