全球首台20兆瓦风机成功过吊装

Core Viewpoint - The successful installation of the world's first 20-megawatt offshore wind turbine in Fujian marks a significant breakthrough in China's development and manufacturing of large-capacity wind turbines and offshore construction capabilities [1][2]. Group 1: Installation Details - The turbine was installed over 30 kilometers offshore in waters deeper than 40 meters, facing challenges such as a short construction window during the monsoon season and complex sea conditions [1]. - A fourth-generation wind turbine installation vessel with a lifting capacity of 2000 tons was utilized, employing high-precision positioning and intelligent pile sinking control systems for the installation [1]. Group 2: Technological Innovations - The 20-megawatt offshore wind turbine is a key project supported by the national key research and development program and is included in the National Energy Administration's list of major technological equipment [2]. - The turbine features 100% domestically produced key components and has achieved innovations in three technical areas: lightweight design, intelligent monitoring systems, and efficient aerodynamic performance [2]. - The overall weight of the turbine (including nacelle, hub, and blades) is less than 40 tons per megawatt, reducing installation difficulty and foundation construction costs by over 20% compared to industry averages [2]. Group 3: Environmental Impact and Future Prospects - Once connected to the grid, the turbine is expected to generate over 80 million kilowatt-hours annually, meeting the electricity needs of approximately 44,000 households for a year, while saving about 24,000 tons of standard coal and reducing carbon dioxide emissions by around 64,000 tons [2]. - The 20-megawatt offshore wind turbine will serve as a comprehensive testing platform for the design, manufacturing, construction, and standard-setting of future large-capacity turbines, providing valuable data and practical experience [2].
