Design and analysis of semi-submersible offshore floating wind and photovoltaic platforms

Abstract

The ocean holds excellent potential for green energy, and the sea can provide green energy to humans. For offshore structures and green energy development, the current floating offshore system has a single function and cannot fully utilize green energy. Therefore, this paper combines the development of wind and solar power to design a floating offshore structure. The report determined the configuration design of the platform and decided to choose a semi-submersible platform, select the type and size of wind turbine and photovoltaic panel models, calculate the wind load and wave load that the platform is subjected to, and finally calculate the cost of the forum. The wind load on a single wind turbine is estimated to be 26590.14N, and the wind load on all PV panels is 216180N, costing about 18487 RMB/kW. In this paper, the close combination of photovoltaic and wind power generation can guarantee the effective implementation of renewable energy and then improve the wind power generation and photovoltaic power generation application system based on the effective combination of the two.
