Chinese wind turbine manufacturer Goldwind has produced a nacelle for a 22 MW offshore wind turbine at its Shantou manufacturing base, according to reports from Chinese media and the company’s supplier of cooling and lubrication systems for the turbine, Chuanrun.
Goldwind presented the rolled-out nacelle during the Shantou International Offshore Wind Power Technology Innovation Conference held from 4 to 5 December 2024, which also saw the launch of the Offshore Wind Power Equipment Manufacturing Industrial Park established at Shantou International Wind Power Innovation Port, CCTV News reported on 7 December.
According to news shared by Chuanrun on 12 December, the new 22 MW wind turbine has a rotor diameter of 300 metres with blades nearly 150 metres long and a sweeping area of 70,000 square metres, equivalent to 10 standard football fields.
Goldwind presented the new offshore wind turbine platform with a 300-metre rotor at the Beijing International Wind Energy Conference and Exhibition in October. The model, GWH300-20 (25) MW , has a single-unit generation capacity of between 20 and 25 megawatts and is suitable for installation in deep waters with water depths from 50 to 70 metres, where it can withstand super typhoons with wind speeds of more than 60 m/s, according to Goldwind .
The new model has undergone more than 2,000 tests on materials, components, subsystems, whole machines, digital twins, as well as the verification mechanism to ensure the stable operation of the unit in severe sea conditions, the company said in October.
In 2023, Goldwind, in cooperation with China Three Gorges (CTG), installed a 16 MW wind turbine with a 252-metre rotor at the site of of CTG’s Zhangpu Liuao offshore wind farm in Fujian Province. At the time, this was the biggest wind turbine installed, until Mingyang installed its 16 MW turbine with a 260-metre rotor at an onshore test site.
