Core Viewpoint - The successful installation of the world's first 20 MW offshore wind turbine in Fujian marks a significant breakthrough in China's development and manufacturing of ultra-large capacity wind turbines and offshore construction capabilities [1][7]. 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, complex sea conditions, and high-altitude operational risks [3][7]. - 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 to smoothly elevate three giant blades, each 147 meters long, to a height of 174 meters for precise hub connection [3][7]. Group 2: Technological Achievements - The 20 MW turbine is part of a national key research and development project and has been included in the list of major technological equipment by the National Energy Administration [5]. - The turbine achieved 100% localization of key components and made breakthroughs in lightweight design, reducing the weight per megawatt by over 20% compared to the industry average, effectively lowering installation difficulty and foundational construction costs [5]. Group 3: Environmental Impact - Once connected to the grid, the turbine is expected to generate over 8 million kilowatt-hours annually, sufficient to meet the electricity needs of approximately 44,000 households for one year, equivalent to saving about 24,000 tons of standard coal and reducing carbon dioxide emissions by approximately 64,000 tons [7].
