On January 11, TMT's self-developed TMT126BA floating wind turbine blade was successfully hoisted at the Wind Power Equipment Testing and Certification Innovation Base in Dongying, Shandong. This blade is mounted on the world's largest floating wind turbine—CRRC's "Qihang" 20MW floating offshore wind turbine, which represents the optimal solution for the development of deep-water offshore wind power resources.
The TMT 126BA floating wind turbine blade is 126 meters long with a sweeping area of 53,000 square meters, equivalent to seven standard football fields. The blade's tip speed matches that of high-speed trains. Designed for the 20MW floating offshore wind turbine, this blade operates for approximately 3,500 full-load hours per year at the design wind speed, with a 25-year service life. Each rotation of the turbine can meet the electricity needs of a household for 2 to 4 days, saving about 25,000 tons of coal consumption and reducing carbon dioxide emissions by approximately 62,000 tons annually.
Achieving high performance and lightweight design, TMT's wind turbine blade R&D team used their self-developed multi-parameter, multi-objective optimization design platform to iteratively optimize blade structures with different configurations and material distributions. This approach maximized the application efficiency of high-performance new materials in the blade structure, balancing blade performance, weight, and cost optimally.
The blade uses a high-quality, efficient preparation process, with a pultruded main beam and integrated shell infusion molding technique. This process eliminates the need for traditional pre-fabrication of the main beam, significantly improving blade forming efficiency and reducing mold investment. Additionally, key structural components are modularly prefabricated to address the challenges of forming ultra-large blades, including difficult shaping operations and long mold cycles.
For deep-water offshore environments, TMT developed a custom rain erosion-resistant and damage-resistant leading-edge protection film, which greatly enhances the blade's leading-edge protection capabilities. In response to the frequent lightning strikes in deep-water offshore areas, TMT also developed a new, efficient lightning protection system to provide comprehensive protection for the super-large blades at sea.
Aligned with CRRC's "dual-track, dual-cluster" industrial development strategy, TMT will continue to provide superior solutions for the development of deep-water offshore wind power resources, with flagship products like the TMT 126BA floating wind turbine blade. This effort will contribute to achieving the "dual carbon" goals and inject significant momentum into the global green energy development.
