The successful roll-off of Wenchong marks a milestone achievement in the "Development of Offshore Floating Wind Power Equipment" project of the Ministry of Industry and Information Technology, and has laid a solid foundation for my country's offshore wind power to move into the deep sea.

The floating platform that will roll off the assembly line will be equipped with a 6.2MW offshore wind turbine from China Sea, and will be used for demonstration in the Dousha area of Xuwenluo, Zhanjiang City, Guangdong Province early next year. The platform has the following features: (1) "Shuyao" can be applied to water depths of not less than 50m and ocean currents of not less than 3.5m/s, and can withstand the once-in-a-hundred-year marine environmental conditions. Partial structure modification (2) It can be applied to various sea areas, equipped with 6.2MW anti-typhoon type I wind turbine, which is currently the largest floating wind turbine in China. It adopts the technical route of three blades, upwind direction, variable pitch speed, three-stage gearbox speed increase, permanent magnet generator + full power inverter, with high power generation, high reliability, high safety, high integration and high maintainability Sex and other characteristics. (3) It adopts a column-stabilized platform configuration with an equilateral triangle layout, consisting of a vertical column, a heave plate, a lower floating body and an upper square brace. With a flat lower floating body, functions such as buoyancy, additional mass, damping and structural support between columns can be concentrated on the flat lower floating body, which helps reduce the amount of floating body engineering. (4) 3*3 point catenary mooring is adopted, which is symmetrically distributed; the mooring cable adopts the form of anchor chain, which has a long life and is maintenance-free; the anchor points are shared to save costs. (5) The integrated modeling and simulation analysis method of wind turbine-floating body-mooring system is adopted to ensure the overall matching of the unit, reduce the load through integrated iterative calculation, and minimize the overall cost of floating wind power equipment.
