On December 20, 2023, the retrofitting project of marine wind-rotor assisted propulsion system manufactured by Dealfeng New Energy Technology (Tianjin) Co., Ltd (short for "Dealfeng New Energy") was successfully completed in DSIC Shanhaiguan Shipbuilding Industry Co., Ltd. (SHGSIC), and passed the acceptance of Offshore Oil Engineering Co., Ltd. (short for "COOEC"). It is China's first commercial delivery project of wind-rotor assisted propulsion system installed on ship, and Dealfeng New Energy is the first company in the world that is able to provide the design and manufacture of marine wind-rotor assisted propulsion system and the turnkey services of installation and retrofitting general contracting projects. The successful delivery of the project also made Dealfeng New Energy the first company in China to commercialize marine wind-rotor assisted propulsion system. Though the delivery schedule was tight, with the strong support and assistance of CCS Jiangsu Plan Approval Center, CCS Tianjin Branch, CCS Guangzhou Branch, CCS Qinhuangdao Branch, Ningbo High-Tech Park Haixing Ship Design Co., Ltd. and DSIC Shanhaiguan Shipbuilding Industry Co., Ltd., Dealfeng New Energy took only 106 days to complete the project delivery from retrofitting contract signed to vessel delivered, which created a world record for the fastest delivery of similar products!




The HAI YANG SHI YOU 226, a world-wide 18,000 DWT deck carrier with 153 meters in LOA and 40 meters in breadth moulded, was retrofitted with two (2) sets of 4-meter diameter and 18-meter height Dealfeng wind-rotor assisted propulsion system. On September 5, 2023, the retrofitting project was signed and launched, then started drawings apprval and equipment manufacturing. On December 7, 2023, the vessel entered the SHGSIC dock for deck retrofitting and equipment installation, finally completed the sea trial and delivered the vessel on December 20, 2023. The deck carrier "HAI YANG SHI YOU 226" fitted with Dealfeng Rotor Sails can realize annual average fuel saving of about 12% during its entire life time.


"The project took only 106 days from from the signing of the contract to the delivery of the vessel, of which it took 86 days to complete the customized design and manufacturing of the rotor sail system and 14 days to retrofit the vessel and install the equipment. During the whole retrofitting process, Dealfeng New Energy overcame the unexpected severe weather such as low temperature of minus 20 degrees Celsius, strong winds and snowstorms to complete the delivery of the vessel equipped with Rotor Sails as schedule, which has created the fastest delivery record in the same industry in the world." Said CEO of Dealfeng New Energy, Li Zhi. "In addition, the Dealfeng wind-rotor assisted propulsion system installed in the project was certified by the world's first Certificate of Type Approval issued by CCS on November 28, 2023. During the process of Type Approval, China Classification Society Headquarters, CCS Shanghai Rules & Research Institute, CCS Jiangsu Plan Approval Center, and CCS Tianjin Branch provide comprehensive technical support and guidance for Dealfeng New Energy in terms of products design, drawings and data review, test procedure preparation, and tests inspection.”


Dealfeng New Energy is a clean energy technology company integrating the R&D, manufacturing and turnkey retrofitting project of marine energy saving and carbon reduction system. Its independently developed Dealfeng® wind-rotor assisted propulsion system, an innovative modernized version mechanical Flettner Rotor that harness the power of green wind to generate auxiliary propulsion thrust for ships through Magnus effect, has filled the gap in similar domestic products, and was granted by the first Certificate of Approval in Principle (AiP) in China from CCS on April 10, 2023. Dealfeng New Energy can provide shipping companies with customized energy-saving and carbon-reducing solutions for new-build ships and existing ships according to different ship types, and its system can effectively improve the EEDI/EEXI/CII and other energy efficiency indicators of the ship, and help the ship achieving annual fuel savings and emissions reduction of 5%-25%, and even more, increasing the commercial added value of the ship.


In the context of the promotion of "Carbon Peak & Carbon Neutrality" in global shipping industry, there will be more and more shipowners and shipyards who will select wind assisted propulsion system as one of important solutions to reduce fuel consumption and carbon emission in the future. Dealfeng Rotor Sail System will effectively facilitate to reach net-zero GHG emissions goal set by IMO from international shipping by or around 2050.
