Design of semi-submersible offshore power generation platform based on green energy utilization

In recent years, wind energy is receiving increasing attention as a non-polluting, renewable, efficient and clean marine green energy source, and countries around the world are already stepping up their development and utilization of wind energy. This paper discusses the design parameters and data analysis of a feasible semi-submersible offshore wind power platform based on the integrated use of green energy for economic purposes under given hydrographic conditions. The design parameters of the power platform include the combination of a circular floating platform, columns, 4.2 MW turbine, floats, and trusses and their respective dimensions, while the data analysis emphasizes the initial stability analysis by verifying the distance between the steady center floats, the wave load calculation by calculating the magnitude of the Morrison force on the floats in waves, the wind load calculation by using static theory to deal with the structural forces at constant wind speed and the cost calculation by adding up the costs of various items. The results of the data analysis show that the designed platform has good initial stability, can withstand wave and wind loads under the design conditions, and that the cost of the materials used in the structure is reasonable. The draft design presented in this paper is expected to provide an alternative design for upgrading existing offshore power generation platforms, achieving a combined use of solar and wind energy, and reducing the cost of building semi-submersible offshore power generation platforms.
