2023-09-12 17:10


Recently, Shanghai Waigaoqiao Shipbuilding Co., Ltd., a subsidiary of China State Shipbuilding Corporation, and Dealfeng New Energy Technology (Tianjin) Co., Ltd. signed a joint research and development agreement on a new ship type equipped with wind-rotor assisted propulsion system for green dual-fuel Aframax tankers that will be certified by AIP certificate from Class. It is also the first development agreement for new ship type signed by a China's rotor sail supplier and a shipyard to install wind-rotor assisted propulsion system .


Under the global policy call of the 'carbon peak and carbon neutrality', the signing agreement also means that more shipyards and shipowners will consider and select wind assisted propulsion - rotor sail system as an important solution for energy saving and carbon reduction in the future.



Dealfeng New Energy Technology Ltd. is a Chinese clean energy technology company integrating the R&D and manufacturing of marine energy saving and carbon reduction system. Dealfeng Rotor Sails is a modern mechanical sail that harness green wind energy to provide auxiliary power for ship through Magnus effect, also is an innovative energy efficient technology advocated by IOM and includes in the EEDI formula. Dealfeng can provide energy saving and carbon reduction solution for newbuilds and existing ships of different ship types according to the customer's specific requirements. At present, Dealfeng has obtained the AIP certification of rotor sail system from several major Classes such as CCS, LR and NK, and has the ability to manufacture and install rotor sails in a diameter of 2m/3m/4m/5m and in a height of 8m-35m with three types foundation such as fixed, folding and rail. Besides, the whole system of Deal Rotor Sail has independent intellectual property rights, and it can achieve the yearly fuel saving of 5%-25% and effectively improve the energy efficiency indexes of ships such as EEDI/EEXI/CII.


Currently, Dealfeng New Energy Technology Ltd. and CNOOC Offshore Oil Engineering Co., Ltd. has signed the contract of 'HAI YANG SHI YOU 226 retrofitting project', which is the first commercialized project of wind-rotor wind propulsion system in China. At the same time, the new-build 5000 DWT product oil tanker that is expected to be delivered at the beginning of 2024 will install one set Dealfeng rotor sail system onboard.


Through the close collaboration between Dealfeng New Energy Technology Ltd. and Waigaoqiao Shipyard, and with the strong support of the Class, it is ensured that the new ship type - green dual-fuel Aframax tanker equipped with rotor sail system will successfully completed, promoting the green and low-carbon development of the international shipping industry.
