Abstract

The invention relates to a manufacturing method of an offshore wind turbine base. The wind turbine base comprises a tower tube lower end and a seabed foundation connected with the tower tube lower end. Through improvement of all the steps of manufacturing methods of the tower tube lower end and the seabed foundation, the service life of a whole offshore wind turbine is greatly prolonged.

Description

technical field [0001] The invention belongs to the fields of alloy heat treatment and wind power generation, and in particular relates to a method for preparing a base of an offshore wind power generator. Background technique [0002] Offshore wind turbines are attracting more and more attention due to the relatively low cost of offshore land. However, due to the construction of wind turbines offshore, the construction cost of the base is much higher than that on land. The base not only needs to be heavy enough to support the impact of waves, but also to avoid maintenance as much as possible. Since the cost of underwater maintenance is much higher than that on land, this requires the base to be very corrosion-resistant and strong, but the cost It cannot be increased too much, and the composition of seawater in different sea areas is different, and the anti-corrosion situation of the base also needs to be treated separately. Contents of the invention [0003] The inventio...
