Sweden’s Wallenius Marine is making progress towards building the world’s first wind-powered PCTC (pure car and truck carrier) by conducting advanced wind tunnel tests to confirm its design. These tests are being carried out in Gothenburg by RISE Maritime Department using one of Europe’s most advanced wind tunnels with wind speeds of up to 250 km/h. The tests involve a 5 x 2 meter model constructed by RISE Maritime to simulate the full aerodynamic performance of the ship, including the interaction between the vessel’s hull and six high-tech wing sails.
The wind tunnel tests aim to not only confirm the design of the wind-powered PCTC but also contribute to the development of new data simulation models for such ships. The areas being tested include the optimal distance between the hull and wing for maximum performance, different types of command bridges, and how off-design conditions affect the ship’s operation. Carl Fagergren, senior project manager at Wallenius Marine, emphasized the importance of ensuring the design meets all technical and operational requirements before finalizing the tender design.
Representatives from KTH, RISE SSPA, and Oceanbird are also present in Gothenburg for the wind tunnel tests, providing expertise and technical knowledge to the project. The collaboration between these entities aims to push the boundaries of wind-powered ship technology and pave the way for more sustainable maritime transportation. The tests will provide valuable data for the development of wing control systems and further advancements in wind propulsion technology.
