China Huaneng announced on the 7th that its Shandong Peninsula North Offshore Wind Power Project, located in the northern Yellow Sea, was fully connected to the grid and began generating electricity that day. This is my country's deepest offshore wind power project, marking a new breakthrough in key areas such as complex deep-sea environments, large-capacity turbine integration, and high-precision intelligent construction.
This project has a total installed capacity of 504,000 kilowatts, with 42 12-megawatt wind turbine generators installed. The site is located about 70 kilometers offshore, in water depths of 52 to 56 meters, making it the deepest commercial offshore wind power project in my country. It will generate about 1.7 billion kilowatt-hours of electricity annually and save about 500,000 tons of standard coal each year.
The project overcame challenges such as complex geology in deep-sea areas, frequent extreme sea conditions, and ultra-long-distance construction. It innovatively applied a four-pile jacket foundation structure, reaching a maximum height of 83.9 meters, which is the tallest of its kind in China. This effectively ensures the safe and stable operation of the wind turbine in complex geological environments in deep-sea areas.
The project developed high-precision positioning technology based on the BeiDou Navigation Satellite System, achieving millimeter-level positioning for seabed pile driving. Combined with intelligent assisted sinking technology, the operation time for single wind turbine pile driving in deep-sea areas was reduced from 48 hours to 29 hours. Simultaneously, with the assistance of drones and artificial magnetic field coordination technology, a 95.6-kilometer-long submarine cable was laid.
