Core Viewpoint - The delivery of the core equipment for the Yingqiang offshore wind power project, including the largest single-unit capacity offshore wind power jacket in Europe, signifies a major breakthrough in China's core construction capabilities for offshore wind power products [1]. Group 1: Project Details - The delivered core components include three jackets and eleven monopile transition pieces, with a total weight of 13,850 tons [3]. - The jacket stands at a height of 95.19 meters, representing China's first internationally built steel pile wind power jacket, which involves high structural connection and protection difficulties, as well as complex construction processes [3]. Group 2: Technological Innovations - The project has pioneered the "side V" construction technique for wind power jackets and employs "modular pre-assembly + real-time monitoring and calibration" technology, achieving a joint precision control within the sub-millimeter level [5]. - The company has independently developed high-strength steel welding technology, successfully passing low-temperature impact welding tests at -50℃, achieving 100% domestic construction of core structures and filling a technological gap in the domestic field [6]. - The precise control of welding temperature and structural deformation has resulted in a welding first-pass qualification rate exceeding 99% [6].
