China Railway Construction Corporation (CRCC) has successfully completed the installation of the fir

On May 25th, with the smooth docking of the rotor blades for the 17th wind turbine, the installation of the first turbine at the Yangjiang Qingzhou offshore wind power project was successfully accomplished by CRCC's New Energy Division. This installation marks the first turbine installed after the upgrade and modification of the "CRCC Wind Power 01" installation vessel, and it is also the largest offshore wind turbine ever installed by China Railway Construction Corporation.

The Yangjiang Qingzhou offshore wind power project is located in the waters near Shaba Town, Yangxi County, Yangjiang City, Guangdong Province. The water depth ranges from 35 to 43 meters, with a distance of 50-55 kilometers from the shoreline (the Qingzhou 1 project has a capacity of 400,000 kilowatts, with a water depth range of 35-38 meters and a distance of approximately 50 kilometers from the shoreline; the Qingzhou 2 project has a capacity of 600,000 kilowatts, with a water depth range of 37-43 meters and a distance of approximately 55 kilometers from the shoreline). The planned installed capacity is 1,000 megawatts, with a total of 92 domestically manufactured typhoon-resistant offshore wind turbines, each with a capacity of 11 megawatts. The two projects will jointly build a 500-kilovolt offshore booster station and an onshore centralized control center. The electricity generated by the wind turbines will be transmitted to the offshore booster station through a 66-kilovolt submarine cable and then further transmitted to the grid through a 500-kilovolt submarine cable connected to the onshore control center. The wind turbine model for the project is the Mingyang Intelligent "MySE11MW" wind turbine, with a blade length of 111.5 meters and a rotor diameter of 230 meters. The rotor weighs 269 tons, which presents significant challenges in terms of lifting capacity, height, and lifting tools for the installation vessel.

In the era of grid parity, to rapidly seize the market for large-scale wind turbines, CRCC's New Energy Division actively responded and scientifically deployed the upgrade and modification of the "CRCC Wind Power 01" installation vessel under the leadership and support of the Harbor and Navigation Administration Group. The upgraded "CRCC Wind Power 01" installation vessel now has the capability to install and maintain wind turbines of 10 megawatts and above. This development will enable the Harbor and Navigation Administration Group to better adapt to the rapid development of offshore wind power and meet the installation demands of large-scale wind turbines in the era of grid parity.
