6. The first domestic deep-water offshore wind power project wind turbine jacket was successfully hoisted

At 22:08 on April 12, 2021, the four-pile jacket hoisting of the wind turbine foundation of the 30# machine position of Guangdong Huadian Yangjiang Qingzhou Three 500MW Offshore Wind Power Project was accurately aligned, and the hoisting was successfully completed.

The Qingzhou III project currently uses the industry’s heaviest (approximately 1370 tons) and tallest (approximately 69 meters without pile foundation), the steel pipe pile diameter is 2.8 meters, and the pile length is about 98 meters, the first domestic deep-water offshore wind power project wind turbine jacket. The foundation is the main part of the wind turbine foundation project in conjunction with the 30# machine-position steel pipe pile that was carried out in the early stage of the pile-sinking construction. In the process, after overcoming the problems of complicated sea conditions, difficulty in berthing of ships, high jacket height, large span, and difficulty in hooking, the self-lifting lasted 3 hours and 10 minutes to successfully complete the hoisting construction.

10. The latest research found that: ORNL's new large-tow carbon fiber can reduce the material cost of the main beam of the blade by 40%

Recently, the Sandia National Laboratory in the United States released a new study. Fan blades made of carbon fiber are 25% lighter than traditional glass fiber blades. This means that carbon fiber blades can be made longer and can capture more energy in low wind speed areas. Multi-energy, carbon fiber blades also obtain a longer service life due to the excellent fatigue resistance of carbon fiber. The results of the study show that compared with the common commercial carbon fibers and glass fibers on the market, the new large-tow carbon fibers can bring cost-efficiency and performance improvements to the wind energy industry.

The research team also compared the mechanical properties of new carbon fiber, commercial carbon fiber and standard glass fiber composite materials, combined the test data with ORNL's cost model, and used these data for blade design analysis. The research results showed that it is comparable to commercial carbon fiber. Compared with the use of new large-tow carbon fiber, the compressive strength per dollar can be increased by 56%. Under normal circumstances, manufacturers will use more materials to manufacture parts to adapt to lower compressive strength, resulting in an increase in material costs. Taking into account the increase in compressive strength per unit cost of the new carbon fiber, the research team predicts that compared with commercial carbon fiber, the material cost of the main beam of the blade made of the new carbon fiber will be reduced by 40%.
