Analysis of the Principles of Marine Green Energy Building Design

Abstract

The depletion of mineral resources on land, the increasingly bad environmental problems, and the beginning of the marine blue encirclement movement in the early 21st century mean that ocean energy has gradually become the focus of human resources development. To better develop and utilize marine green energy, we study the sea level according to specific sea conditions. A semi-submersible offshore platform is designed to collect and use offshore wind and solar power. In this paper, the semi-submersible platform is introduced from the design concept, initial stability calculation, load calculation and cost calculation. Through the measure of wind load, wave load and stability, the offshore platform can normally work under specific sea conditions. In this paper, it is calculated that the unballast center of gravity of the whole structure is 41.31 meters, the floating center of the system is 9.23 meters, and the center of gravity is under the steady center. The result of the wind load calculation is 21990110.4 N, the total cost of the whole semi-submersible platform is 170340458.14 RMB, and the unit cost is 14195.0381784 RMB/kW. This paper looks forward to designing a semi-submersible platform with solid stability and high efficiency in the collection of wind energy and light energy, and hopes to alleviate the environmental problems and make people pay more attention to the use of marine green energy.
