Wallenius Marine is conducting advanced wind tunnel tests in Gothenburg as part of its efforts to develop the world’s first wind-powered Pure Car and Truck Carrier (PCTC). The tests are taking place in one of Europe’s most sophisticated wind tunnels, capable of simulating wind speeds of up to 250 km/h.

The initiative brings together Wallenius Marine, RISE, KTH, and Oceanbird to validate the latest design for the innovative vessel. This collaboration is not only focused on confirming the vessel’s design but also on contributing to the development of new data simulation models for wind-powered ships, an essential step in advancing sustainable maritime transport.

Key areas being examined include the interaction between the hull and six advanced wing sails, the optimal spacing between the hull and wings for peak performance, and the impact of three different command bridge designs on overall efficiency. Tests also explore operational challenges under “off-design conditions,” such as when a wing sail is misaligned, and provide data for developing advanced wing control systems.
