Xinhua News Agency, Beijing, April 7 (Reporter Dai Xiaohai) China Huaneng announced on April 7 that the North Sea offshore wind power project on the northern part of the Shandong Peninsula in the northern part of the Yellow Sea achieved full-capacity grid-connected generation that day. This is the offshore wind power project with the deepest water depth in China, marking new breakthroughs in key areas such as deep-sea and far-offshore complex conditions, integration of high-capacity units, and high-precision intelligent construction.

The project has a total installed capacity of 504k kW. It will install 42 wind turbine generator sets of 12 MW each. The center of the site is about 70 kilometers offshore, with a water depth of 52 to 56 meters. It is the offshore wind power project with the deepest water depth in China operating commercially. The annual power generation is about 1.7 billion kWh, and it can save about 504k tons of standard coal each year.

The project overcame challenges such as complex geology in deep-sea and far-offshore areas, frequent occurrences of extreme sea conditions, and ultra-long-distance construction. It innovatively applied a four-pile jacket foundation structure, with a maximum height of 83.9 meters—the highest among domestic projects of the same type—effectively ensuring the safe and stable operation of wind turbines in deep-sea and far-offshore complex geological environments.

Relying on the BeiDou system, the project developed high-precision positioning technology, enabling millimeter-level construction positioning for pile driving on the seabed. Combined with intelligent assisted piling and lowering technology, it reduced the time required to drive piles for a single wind turbine in deep-sea and far-offshore areas from 48 hours to 29 hours. At the same time, with the help of drone and manual magnetic-field coordination technology, it completed the laying of 95.6 kilometers of ultra-long submarine cables.
