Self-stabilized multi-column offshore floating wind power Spar platform

Abstract

The invention discloses a self-stabilized multi-column offshore floating wind power Spar platform. The self-stabilized multi-column offshore floating wind power Spar platform is characterized by comprising a central column and a wind turbine arranged at the upper end face of the central column, the lower end face of the central column is provided with a center stand column, the diameter of the center stand column is greater than that of the central column, the periphery of the center stand column is provided with a plurality of side stand columns, the side stand columns fit the center stand column, the lower end of the center stand column is provided with a damping plate, the damping plate is arranged horizontally, the center stand column is connected with a mooring system, the center stand column and the side stand columns are provided with a plurality of compartments respectively, the lowest compartment of the same center stand column or side stand column is a fixed ballast compartment, and the compartment, located above the fixed ballast compartment, of the same center stand column or side stand column is a ballast adjustment compartment. The self-stabilized multi-column offshore floating wind power Spar platform has the advantages that the requirement for the water depth can be effectively reduced, and the application range is increased.

Description

technical field [0001] The invention relates to a floating foundation of an offshore wind power machine, in particular to a self-stabilizing multi-column offshore floating wind power Spar platform. Background technique [0002] Compared with onshore wind, sea breeze has many advantages such as high wind speed, less quiet wind period, small change of wind speed with height, no need to limit noise, etc., which can greatly increase the power generation of wind turbines and prolong their life. In addition, the cost of space at sea and Compared with land, it has unique advantages and is suitable for large-scale development and utilization of high-quality wind energy. As the water depth increases, the cost of fixed offshore wind turbine foundations increases sharply. In order to improve economic applicability, floating foundations have become an inevitable choice for wind turbine development in deeper sea areas. [0003] Currently, the commonly used floating foundations for offsh...

AI Technical Summary

Problems solved by technology

[0006] The existing mainstream floating foundations have their own shortcomings and limitations, and most of the floating platform concepts currently proposed are aimed at the characteristics of European coastal waters. Considering that China's offshore wind resources are mainly distributed in shallower water depths (40m- 120m) in the East China Sea and South China Sea, it is obvious that the existing offshore floating wind turbine foundation cannot adapt to the actual sea conditions in China, so it is difficult to promote and apply. A new type of offshore floating wind turbine foundation with high sea area, strong economy and excellent comprehensive performance
