Tension leg platform-wind turbine double-body modular floating integrated system and use method thereof

Abstract

The invention discloses a tension leg platform-wind turbine double-body modular floating integrated system and a use method thereof, and belongs to the field of marine energy utilization. The system comprises a wind turbine module, a tension leg platform module, a tension leg system and platform-wind turbine tower frame clamping devices, wherein the center of the tension leg platform module is provided with a sleeve with the inner diameter larger than the outer diameter of a wind turbine module tower frame, and the platform-wind turbine tower frame clamping devices symmetrically arranged in the sleeve in a vertical and multi-layer mode enable a rubber plug to extend to a wind turbine tower frame through adopting a gear driving mode, and also enable the wind turbine tower frame to be clamped and butted with a tension leg platform so that the relative movement between the wind turbine module and the tension leg platform module can be limited. According to the tension leg platform-wind turbine double-body modular floating integrated system and the use method thereof, the wind turbine module has the self-balancing property, and the installation of the wind turbine module and the tension leg platform module does not change the pre-tension level of the tension leg system; meanwhile, the fault tolerance performance during the process of vertical butt joint assembling / disassembling ofa floating offshore wind turbine is further increased, and the compatibility is also remarkably enhanced; and finally, the tension leg platform is made of a fatigue-resistant corrosion-resistant FRP material, so that full-life service support can be provided for two large-sized offshore wind turbines.

Description

technical field [0001] The invention belongs to the field of ocean energy utilization, relates to technologies such as the design, installation, operation and maintenance, and removal of the entire life cycle of a tension leg wind turbine structure, and provides a tension leg platform-wind turbine two-body modular floating integrated system and its use method. Background technique [0002] In recent years, due to the deterioration of the global environment and the energy crisis, countries all over the world have turned their attention to offshore wind energy development, planning to improve the energy structure by building offshore wind farms. Offshore wind energy resources are abundant and more stable than onshore wind power. Therefore, in recent years, countries have continuously strengthened the research and construction of offshore wind turbines. However, for countries such as Norway, the United States, and China, the huge potential of offshore wind resources is mainly ...

AI Technical Summary

Problems solved by technology

[0004] The shortcomings of the existing technology are: the installation of offshore wind turbines needs to realize the docking of the wind turbine tower and the tower on the offshore foundation. While ensuring the accuracy of the docking, it is necessary to avoid collision damage during the installation process.

At present, there is still a lack of modular combination systems for offshore wind turbines on floating platforms that can be easily loaded and unloaded and have good compatibility.
