Problems solved by technology
[0004] The traditional Spar floating platform is a cylindrical structure. The mooring system is directly connected to the cylindrical platform by three mooring anchor chains. Due to the small rigidity of the mooring system, the platform will have a large motion response, which exacerbates platform vibrations and reduces system stability
Moreover, for sea areas with relatively harsh sea conditions, the environmental loads borne by the wind turbines are more complex, and the floating platform produces a greater motion response, which affects the normal operation of the wind turbines.

The invention belongs to the technical field related to offshore floating-type wind power generation and discloses a bifurcation mooring line-type fan mooring system and offshore wind power generationequipment. The mooring system comprises a floating-type platform, two heaving plates, multiple mass blocks and multiple mooring anchor cables. The two heaving plates are arranged in the middle of thefloating-type platform at an interval; the ends of the mooring anchor cables are connected to the two heaving plates respectively, the other ends of the mooring anchor cables are used for being connected to mooring anchor points, and the mooring anchor points are arranged at the seafloor; the mass blocks are connected to the mooring anchor cables respectively; the floating-type platform is cylindrical, and the mooring anchor cables are evenly distributed around the center axis of the floating-type platform; the number of mass blocks is identical to that of the mooring anchor cables. Accordingto the system, the motion response of a fan is effectively reduced, the stability is improved, the cost is low, the applicability is high, the structure is compact and reasonable, and construction iseasily and conveniently conducted.
Description
technical field [0001] The invention belongs to the related technical field of offshore floating wind power generation, and more specifically relates to a bifurcated mooring line type fan mooring system and offshore wind power generation equipment. Background technique [0002] With the massive consumption of fossil energy such as petroleum, the problems of energy and environmental pollution have become increasingly prominent around the world, and the seriousness of global warming and climate deterioration is becoming an important challenge facing the world. Wind energy, as a clean and renewable energy, can well solve the problem of shortage of traditional energy in the world today, and has attracted more and more attention. At present, most of the wind power projects are on land and in shallow sea areas. With the development of wind power technology, offshore wind power has gradually become a new field of wind power. Because the offshore area is rich in wind resources and ...
