CRRC, a state-owned Chinese language language agency, effectively hoisted the world’s largest floating wind turbine on the Shandong Dongying Wind Vitality Instruments Testing and Certification Innovation Base, on January 11, 2025.
The turbine named “Qihang” is a 20MW floating offshore wind turbine, independently designed by CRRC. It was manufactured in Sheyang, Jiangsu, and rolled off the manufacturing line in October 2024.
In mid-December, the turbine was transported from Sheyand Port to Guangli Port in Dongying using a self-propelled modular transport unit sooner than being moved to the check out site for hoisting.
The turbine has a rotor diameter of 260 meters (853 toes), equal to seven soccer fields, and a hub prime of 151 meters (495 toes). Each rotation of the turbine can generate enough electrical power to provide a household for 2 to 4 days.
Over a yr, it’d most likely operate for about 3,500 hours, saving 25,000 tons of coal and reducing carbon dioxide emissions by 62,000 tons. It is designed to closing 25 years.
The turbine integrates superior administration packages to ensure stability and minimise motion, even in tough sea conditions. It incorporates numerous typhoon-resistant utilized sciences to withstand extreme local weather.
The design focuses on modular improvement for flexibility, effectivity and reusability of key components.
The turbine is being examined with over 200 monitoring elements to guage its effectivity under varied wind, wave, and current conditions. These assessments cowl very important components like blades, frames, transmission packages, towers, floats, and mooring packages.
CRRC is using built-in simulation testing to analyse aerodynamic, structural, and hydrodynamic responses, guaranteeing reliable operations.
The “Qihang” outperforms totally different prototypes, like Envision Vitality’s 16.7 MW unit and Dongfang Electrical’s 18 MW turbine, which began testing in June 2024.
Whereas China’s Mingyang Wind Vitality is engaged on a 22 MW turbine anticipated later this yr, the “Qihang” presently leads in dimension and performance.
After worthwhile testing and certification, the turbine shall be deployed in deep-sea areas for grid-connected power know-how. China has already surpassed the UK to have crucial offshore wind arrange base and targets to dominate the worldwide market.
