Wallenius Marine is currently conducting advanced wind tunnel tests in Gothenburg, Sweden, with the aim of creating the world’s first wind-powered pure car and truck carrier (PCTC). The tests are taking place at one of Europe’s most advanced wind tunnels, where wind speeds can reach up to 250 km/h. Experts from RISE KTH and Oceanbird are working alongside Wallenius Marine to confirm the design and develop new data simulation models for wind-powered ships.
RISE Maritime Department (formerly SSPA) is overseeing the tests and has constructed a 5 x 2 meter model that weighs 1.2 tons. This model is used to simulate the full aerodynamic performance of the ship in the wind tunnel. Unlike previous tests that focused on wing sails independently, this test is unique as it combines the hull and multiple wings in a large tunnel with a full-scale model. The tests aim to analyze the interaction between the vessel’s hull and six high-tech wing sails, determine the optimal distance between hull and wing for maximum performance, test different types of command bridges, and assess how “off-design conditions” impact the ship’s operation.
The wind tunnel tests will provide valuable data for the development of wing control systems for wind-powered ships. By testing various scenarios, such as different wing positions and hull-wing distances, the experts aim to optimize the design of the wind-powered PCTC. This groundbreaking project represents a significant step towards sustainable shipping and reducing reliance on traditional fossil fuels.
