Description
Technical Field

Background
At present, offshore wind power projects are mainly developed for offshore wind power resources, and with the technical development of offshore wind power, the trend of the development towards deep and distant sea is a necessary trend. At present, foundations used in offshore areas are mainly fixed supporting foundations, but the foundations have strict requirements on water depth. Along with the increase of the water depth, the self weight and the engineering cost of the traditional fixed foundation are greatly increased, and the cost of the fixed foundation structure in a deep sea area is far higher than that of a floating foundation structure. The floating foundation breaks through the limit of water depth, and the construction cost is insensitive along with the increase of the water depth. In addition, the floating wind power unit enables the wind power unit to get rid of the constraint of different seabed conditions, so that the basic design is standardized, and the offshore operation is reduced to the maximum extent; different from the traditional offshore wind power generation set, the base is fixed on the seabed, and the fixed anchor cable can be easily released to return to a port when the floating foundation needs to be maintained or avoids typhoon, so that the floating foundation has good maneuverability and realizes reutilization and repeated deployment; compared with the traditional seabed fixed type offshore wind turbine, the floating type offshore wind turbine can contact strong wind at ocean depths, so that the wind energy utilization rate is greatly improved. In conclusion, the floating foundation is expected to become the main type of the next generation offshore wind power foundation.
The floating type basic design concept of offshore wind power is mainly inherited from an offshore oil platform. Mono-columns, semi-submersibles and tension legs are also used by offshore wind power floating foundations as the main types of offshore oil platforms in widespread use. However, the greatest difference between the oil profit and the wind power is that the oil profit is much higher than that of the wind power, the floating foundation of the oil platform is directly applied to offshore wind power, the amount of steel used for the foundation is often too large, and the cost is too high, which is one of the main limiting factors for limiting the development of offshore floating wind power at present.
At present, the global floating offshore wind power is developed in a hundred of flowers, a plurality of projects have already completed theoretical analysis and model test stages, enter a small-scale prototype operation stage, and even enter a commercialization project stage. However, floating offshore wind power facilities are not built in China. Therefore, in order to fully develop the wide ocean wind energy resources in the sea area of China and build the floating type offshore wind power facility suitable for the deep sea area, a novel offshore wind turbine floating foundation structure system with economy and safety needs to be provided.

The upper part of the mooring cable M is connected with the radial steel bracket F.13, and the lower part of the mooring cable M is connected with the seabed, so that the mooring cable M plays a role in positioning and providing stability for the floating system. The suspension chain f.3 and the mooring line M may be of one material, for example. The suspension chain line f.3 and the mooring line M may be, for example, an anchor chain or a composite material.
As shown, the connecting steel bracket f.1 includes a central steel bracket f.11, a diagonal bracing steel bracket f.12 and a radial steel bracket f.13. The central steel bracket F.11, the diagonal bracing steel bracket F.12 and the radial steel bracket F.13 are connected into a whole. The central steel support F.11 is vertically arranged, and the top of the central steel support F.11 is connected with the bottom of the fan tower W.3; the radial steel brackets F.13 are vertically arranged with the central steel bracket F.11 along the radial direction of the central steel bracket F.11, and the included angle between every two radial steel brackets F.13 is 120 degrees; the diagonal steel support F.12 and the central steel support F.11 are arranged at a certain angle, so that the bending moment on the central steel support F.11 is converted into the tension and pressure on the diagonal steel support F.12, and the stress is more reasonable; and an included angle of every two between planes formed by the axes of the inclined strut steel bracket F.12 and the radial steel bracket F.13 is 120 degrees.
The radial steel support F.13 directly penetrates through the buoy F.2 and is anchored by adopting studs and annular steel bar pouring concrete. The mooring cable M is fixed on the radial steel support F.13, the suspension chain rope F.3 is also fixed on the radial steel support F.13, only static water restoring force/moment load is transferred between the buoy F.2 and the radial steel support F.13, the stress is more reasonable, and the stress damage between the buoy F.2 and the radial steel support F.13 is effectively relieved.
As shown, buoy f.2 is a hollow subdivision structure. The pontoon F.2 is divided into a plurality of independent cabins by a pontoon vertical cabin plate F.21 and a pontoon transverse cabin plate F.22.

The buoyancy of the floating system is adjusted by adjusting the amount of ballast water in the individual chambers. The hanging ballast structure F.4 does not have the ability to suspend or float itself, i.e., gravity is greater than buoyancy without filling in any ballast water. The suspension ballast structure F.4 may be, for example, a concrete material with steel reinforcement placed inside to provide structural strength, at a lower cost than conventional steel structures. The suspended ballast structure F.4 may be, for example, a flat cylinder design that increases heave damping, reduces float heave motion, reduces fan nacelle acceleration, more easily meets design requirements, and reduces mooring burden.
