Uni-Tankers’ M/T Jutlandia Swan has been equipped with four windsails, known as VentoFoils, marking a milestone in the Danish Cleanship project.
Funded by the Danish EPA’s MUDP program, the project aims to gather precise data on the practical impact of windsails to strengthen the shipping industry’s efforts to reduce fuel consumption and emissions. With this installation, the project enters a new phase, measuring the real effects of wind-assisted propulsion under actual operating conditions on a commercial vessel.
Furthermore, this demonstration is a crucial step toward delivering data-driven recommendations for emission reduction, enabling shipping companies to make informed decisions about adopting effective technologies and strategies at sea.
Wind-assisted propulsion holds clear potential, but its real value depends on how well it is integrated into daily operations. We now have the opportunity to test how these sails perform at sea, what they mean for fuel efficiency, and how the crew can work with them in practice.
…said Kristian Larsen, Technical Director, Uni-Tankers.
Cleanship is a Danish research and demonstration project (2024–2026) supported by the Danish Environmental Protection Agency’s MUDP programme. The project is led by the Danish Technological Institute in collaboration with Uni-Tankers, Green Instruments, Mærsk Mc-Kinney Møller Center for Zero Carbon Shipping, Danish Shipping Companies and Danish Maritime. The consortium brings together expertise across the sector to test and demonstrate the effect of wind sails and modern biofuels under real-world shipping conditions, and analyse how operational levers affect emissions and fuel efficiency.
