On April 17, 2024, the 725 Institute of China Shipping Group officially released the world's largest marine wind turbine booster system. The size and weight of the system are world records, with a diameter of 5 meters, a height of 35 meters and a weight of 150 tons. Its core function is to efficiently capture wind energy during the ship's voyage and convert it into auxiliary thrust, thereby saving on average 5% to 25% of fuel consumption for large ocean-going ships and reducing greenhouse gas emissions accordingly. This breakthrough marks that China has achieved an important leap from technology following to local leading in the field of high-end ship green energy-saving equipment. According to the relevant person in charge, the rotary sail market has a bright future. It is estimated that more than 7000 ships will be installed with sails in the world by 2030, and the market scale of rotary sail will reach 100 billion yuan, and it is expected to grow to 300 billion billion yuan by 2050. At present, the world's largest rotary drum boost system has completed land-based tests, and its technical maturity has been verified, paving the way for subsequent industrial mass production, and has an important role in promoting the green and low-carbon transformation of China's and even the global shipping industry.
