AI Technical Summary
Technical Problem
The existing floating fan foundation has problems such as large steel use, poor hydrodynamic performance and high cost, which is difficult to adapt to the installation needs of deep-sea wind farms.
Method used
A hybrid floating fan foundation is designed, including a central column and multiple side columns. The lifting position of the settlement column is adjusted through the ballast of the settlement column to realize the versatility of the fan foundation in the towing and installation process.
Benefits of technology
The underwater depth of the fan foundation during the towing process is reduced, the installation process is simplified, complex cross-torque and ballast operations of the column platform are avoided, and the fixed stability of the fan foundation is improved.

Abstract
This invention discloses a hybrid floating wind turbine foundation and a floating wind turbine installation method to solve the problems of large steel consumption, poor hydrodynamic performance, and high cost in existing technologies. The central column includes a fixed column and a sinking column. The sinking column is raised or lowered relative to the fixed column by adjusting the ballast of the sinking column. In towing mode, the sinking column floats, and the draft of the entire wind turbine foundation is small underwater, making it possible to transport the foundation and superstructure together at the dock or tow it to the wind farm after installation. This avoids the complex process of horizontal towing and ballast verticalization required for offshore installation of column-type platforms. In installation and use mode, the sinking column sinks and contacts the seabed or the seabed base platform, facilitating the fixation of the wind turbine foundation. During offshore hoisting of the wind turbine nacelle and blades, the relative movement between the floating foundation platform and the crane on the installation vessel is safely and controllably eliminated.
