Abstract

The invention discloses a novel multi-float-bowl offshore wind turbine floating foundation. The novel multi-float-bowl offshore wind turbine floating foundation comprises a center float bowl, circumferential float bowls, supporting parts, a truss part, a heave plate, a center soft cabin, a mooring system and an anchorage foundation. The truss part is arranged on the bottom of the center float bowl, the heave plate is arranged on the truss part, the center soft cabin is arranged on the bottom of the truss part, the circumferential floating bowls are connected above the center float bowl throughthe supporting parts, the anchorage foundation is arranged below the center float bowl slantly, the side face of the center float bowl is connected with the anchorage foundation through the mooring system, the center float bowl is arranged on the bottom of a fan tower, and a fan is arranged on the top of the fan tower. The floating foundation has the beneficial effects that the novel multi-float-bowl offshore wind turbine floating foundation suitable for deepwater wind power development is provided, the structure is optimized, the structure weight is reduced, the motion property is improved,and the resistivity of the floating type fan foundation to stormy wave flow loads on the complex sea can be improved.

Description

Technical field: [0001] The invention relates to the field of supporting foundations for floating offshore wind turbines, in particular to a novel floating foundation for offshore wind turbines with multiple buoys. Background technique: [0002] As a kind of green energy, wind energy is mainly utilized in the form of wind power generation. At present, the development of onshore wind power and offshore wind power in the world has a certain scale. Compared with land wind energy, ocean wind energy has the advantages of high quality, stability and low interference. However, due to the particularity of the marine environment, there is still a certain gap in the development speed and scale of offshore wind power compared with onshore wind power. According to statistics, my country's total exploitable wind power reserves are about 1000GW, of which 250GW is offshore wind power. By the end of 2018, the total installed capacity of wind power in the world was 592GW, of which the ins...
