Because sea wind and sea waves have natural correlation, the wave energy resources of the water area rich in wind energy are also rich. The offshore wind energy development in the east coast of China is very rich in wind energy resources, has huge resource potential, has good development and utilization market conditions, and is closer to the economic center of China. With the gradual expansion of offshore wind power plants to deep sea areas, the supporting platform structure of the offshore wind power plants gradually develops from a fixed foundation to a floating structure system. At present, a plurality of floating offshore wind power demonstration projects are established worldwide, and China also focuses on a semi-submersible offshore wind power structure system in main research. However, compared with the rapid industrial development of offshore wind power, the wave energy power generation device has lower energy conversion rate and higher unit power generation cost, and thus the large-scale commercial application of the wave energy power generation device is limited to a certain extent.

The wave power generation device has various types, and is not limited to a lattice, and comprises more than ten types, such as a float type, a wave power generation boat type, a ring reef type, a rectifier type, a clam type, a soft bag type, an oscillating water column type, a wave flow type, a pendulum type, a contracted water channel type and the like, wherein the float type structure system is the simplest, and the efficiency is higher.
The defects of the prior art are as follows: with the gradual development of the unit capacity of the offshore wind turbine from 5MW to 10MW or even 20MW, the method also provides a great challenge for the optimal design of a floating offshore wind turbine support platform structure system; the wave energy power generation device is low in energy conversion rate and high in unit power generation cost, and needs to be explored and integrated with relevant ocean structures to achieve cost optimization. At present, a comprehensive ocean energy development structure system integrating a semi-submersible wind turbine and a multi-floater wave energy power generation device into a whole is lacked.
