The 49.2 ft long ship prototype Stena Airmax was named in Gothenburg. The prototype is part of a project in which an air cushion is being tested to investigate to what extent it reduces the friction between the hull and the water, thus also reducing fuel consumption and emissions of large tankers in the future. Stena will invest in the region of $6.8m in the project. Following the very good results achieved in tests with small ship models, Stena Teknik has developed this large-scale model weighing 25 tons. The same tests will now be carried out with the Stena Airmax.
