- Anemoi Marine Technologies Ltd has announced that it is collaborating with Hafnia Limited, 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.
Wind propulsion company Anemoi Marine Technologies Ltd will be working with ship owner Hafnia, Guangzhou Shipyard International (GSI), and DNV on the installation of rotor sails on 50,000 dwt Medium-Range (MR) tanker vessels, reports PSE.
Quartet team up on rotor sails for MR tankers
In a statement, Anemoi said that it will collaborate with Hafnia on 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 look at 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.
Meanwhile, GSI will develop technical documentation for the new rotor sail’s design integration and DNV will undertake an Approval in Principle (AiP) assessment.
Jesper Kristiansen, Hafnia’s General Manager Technical, said: ‘Participating in this joint development project allows us to collaborate with industry partners to unlock the full potential of Rotor Sails on MR Tankers. It supports Hafnia’s decarbonisation strategy to assess and embrace the potential of innovative technologies to improve fuel efficiency and reduce vessel emissions.’
Nick Contopoulos, Chief Production and Partnerships Officer of Anemoi, added: ‘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.’
