Dealfeng, a Chinese provider of wind-assisted propulsion systems, on Tuesday (20 May) said it has assigned a cooperation agreement with Singapore-based shipowner Hung Ze Shipping.

The partnership will equip a new series of 14,000 DWT chemical tankers with Dealfeng® Rotor Sails. 

Each vessel will feature a 5m x 24m Dealfeng Rotor Sail installed on its forecastle deck. Collaborating with maritime software leader NAPA, the project will utilise route optimisation systems to maximise the efficiency of wind-assisted voyages, further enhancing fuel savings and emissions reduction while improving overall energy performance.

“The first vessel in the series is scheduled for delivery with the rotor sail system in the fourth quarter of 2025. Preliminary calculations indicate that the technology will achieve approximately 8% fuel savings on the vessel’s trading routes,” the company said in a social media post. 

The project marked Dealfeng’s first overseas commercial contract for its wind-assisted propulsion technology.

Dealfeng, a clean energy technology company specialising in the R&D, manufacturing, and EPC services of shipborne energy-saving systems, has long focused on developing Wind Assisted Propulsion Systems (WAPS). Its core product, the Rotor Sail, harnesses wind energy via the Magnus effect to provide auxiliary propulsion for vessels. 

Tailored to different ship types, the system offers fuel and carbon emission reductions of 5%–25%, with even greater efficiency under favorable wind conditions. Dealfeng’s Rotor Sail technology has obtained certifications from multiple classification societies and has been successfully deployed across numerous vessels, accumulating years of operational experience that validate its safety, reliability, and effectiveness.

Hung Ze operates a diverse fleet ranging from 5,000 DWT vessels to MR product tankers.

Anemoi Marine Technologies on Thursday (15 May) announced a new partnership with Hafnia, Guangzhou Shipyard International (GSI), and DNV to develop the integration design of Rotor Sails suitable for installation on 50,000 dwt Medium-Range (MR) tanker vessels.

The companies signed a Joint Development Project (JDP) in April 2025 to develop a new generation of efficient and environmentally friendly Rotor Sail vessel designs to increase the efficiency of MR tankers within the wider global fleet.

As part of the project, Anemoi and Hafnia will undertake several engineering studies to establish specifications related to how Rotor Sails can be safely and efficiently installed on the deck of MR tankers, alongside additional electrical and control system layouts for these vessels. 

In addition, the studies will include calculations to examine how Rotor Sails can improve the Energy Efficiency Design Index (EEDI) and Energy Efficiency Existing Ship Index (EEXI) values of existing and future MR tankers.

GSI will apply its naval architecture and marine engineering principles to develop essential technical documentation for the new Rotor Sail’s design integration, while DNV will undertake an Approval in Principle (AiP) assessment to ensure that the design is feasible and verifies that no significant obstacles exist to prevent the design from being realized based on current and foreseeable regulatory and class requirements.

Nick Contopoulos, Chief Production and Partnerships Officer of Anemoi, said: “There is growing interest within the tanker sector for novel technology that can help reduce the carbon footprint of their vessels and increase their value, particularly as the MR tanker fleet is expected to grow in the coming years.”

“Our partnership with Hafnia, alongside GSI and DNV, will ensure a new generation of MR tankers that utilises Rotor Sails to improve their efficiency and sustainability credentials hits the water in the not-too-distant future.”

Mr Shao Guang Chi, Station Manager of Guangzhou Station at DNV Maritime, said: “WAPS, like Rotor Sails, are spreading throughout the industry, enabled by new materials, data and software, and evolving rules and regulations.”

“Across all segments, we still have room to improve vessel energy efficiency and WAPS have emerged as one of the most attractive tools for shipping to make immediate, impactful gains in this area.”
