[0002] Offshore wind power towers are important facilities for generating electricity in marine environments. They are usually used to capture offshore wind energy and convert it into electrical energy. Compared with onshore wind power generation, offshore wind power generation has the advantages of richer wind energy resources and more stable wind speeds. The foundation of an offshore wind power tower must be able to withstand the tower's own weight, wind loads, ice and snow loads and other external forces.
