On April 7th, the deepest offshore wind power project in China, the Huaneng Shandong Peninsula North L site offshore wind power project, achieved full capacity grid connected power generation, marking a new breakthrough in China's offshore wind power in the complex environment of the deep sea and the integration of large capacity units.

The project site center is about 70 kilometers offshore, with a water depth of 52 to 56 meters. 42 12 megawatt wind turbines have been installed, with a total installed capacity of 504000 kilowatts. Based on a household's daily electricity consumption of 10 kilowatt hours, if a wind turbine operates at full load for one hour, the electricity generated can meet the daily electricity demand of 1200 households. The annual power generation of the project is about 1.7 billion kilowatt hours, which can save about 500000 tons of standard coal annually.

With the increasing scarcity of exploitable resources near the coast, it is an inevitable trend for China's offshore wind power to develop towards deeper and farther seas. The wind speed in the deep sea area is higher and the wind conditions are more stable, resulting in a significant improvement in power generation efficiency. However, compared to offshore projects, Far East Wind Power faces more complex challenges in terms of technological breakthroughs, equipment adaptation, and cost control.

It is reported that the project has overcome industry challenges such as complex geology in deep and open seas, frequent extreme sea conditions, and ultra long distance construction. Among them, the innovative application of four pile conduit frame foundation structure can reach a maximum height of 83.9 meters, which is the highest of its kind in China. This is equivalent to building a four legged "steel frame base" for the wind turbine, which is connected by a truss structure to ensure the safety and stability of the wind turbine in the complex geological environment of the deep sea.

The project also relies on the Beidou system to develop high-precision positioning technology, achieving millimeter level construction positioning for underwater pile sinking. Combined with intelligent assisted sinking technology, the operation time for deep-sea single wind turbine pile sinking has been reduced from 48 hours to 29 hours. At the same time, with the help of unmanned aerial vehicles and artificial magnetic field collaborative technology, a 95.6-kilometer ultra long submarine cable was laid.
