Design study of offshore floating wind and photovoltaic power generation platform

Abstract

The oceans contain a huge amount of clean energy, of which wind and solar are the largest reserves and the easiest to access. In consideration of the many factors affecting traditional offshore semi-submersible platforms, the design of an offshore semi-submersible platform that can overcome the harsh marine environment and work efficiently is based on overcoming the many problems of low stability, low efficiency, and poor economy of existing semi-submersible platforms. The text, therefore, builds on previous designs to design an offshore floating platform that combines a floating wind turbine with photovoltaic power generation. Firstly, the paper combines various design concepts, proposes a model concept for the floating platform and the corresponding structural dimensions, designs the ballast system, and selects the materials for each part. The paper concludes with a simple calculation of the stability, loads, and cost of the structure. The overall high initial stability (GM) of the structure is greater than zero, the wind and wave loads are estimated to be 350,000 N and 50 million N respectively, and the cost is about 58,500,000 RMB per kW. The research offers a new approach to the future development of new green energy sources in the ocean and has implications for the design of new integrated concepts for floating platforms. The paper concludes by looking forward to the design of a more stable, economical, and efficient offshore floating power platform that will provide a new way of maximizing the exploitation of offshore energy for human society.
