Offshore wind has two core advantages over onshore wind: higher and more consistent wind speeds (better generation efficiency); and distance from populated areas enabling larger turbine sizes without visual or noise impact. This makes offshore wind a critical renewable pathway for densely populated coastal regions (China’s eastern coast, Europe’s North Sea).
## China’s Offshore Wind: From Follower to Peer
China surpassed the UK in 2022 to become the largest cumulative offshore wind market, adding approximately 13 GW of new capacity in 2023. Chinese turbine manufacturers (Mingyang Smart Energy, Goldwind, DEC, CSSC Haizhuang) have developed 18–20 MW ultra-large offshore turbines comparable in specifications to European leaders (Vestas, Siemens Gamesa), with cost advantages.
**Supply chain advantage**: from towers, blades, main bearings, and converters to complete turbines, China has built a complete offshore wind supply chain. China’s offshore wind construction costs (~¥6,000–8,000/kW) are substantially lower than European equivalents (~¥12,000–18,000/kW equivalent).
## Floating Offshore Wind: The Next Frontier
Virtually all current global offshore wind uses fixed foundations (water depth <50m) anchored to the seabed via monopiles or jackets. China's near-shore shallow-water resources are limited; deep-water areas (>50–100m depth) hold far greater wind resources requiring floating foundation technology to access.
Global floating offshore wind remains in early commercialization (approximately 225 MW globally installed at end-2023); Norway’s Hywind project (Equinor-operated) is the most mature commercial reference. Multiple Chinese floating demonstration projects are advancing (Mingyang’s “wind-fish integration” floating platform in Guangdong, CNOOC’s test project in Hainan). Floating offshore wind is expected to enter scale-up phase in 2025–2030.
