Oceanbird is a massive sailing cargo ship designed to reinvent sustainable ocean shipping and reduce transatlantic travel emissions by 90%. The Swedish collaborative project is still in its sea trials stage but is poised for full-scale production by late 2021 and deliveries by 2024. Conceptually, the wind-powered cargo vessel is designed for car and truck shipments and will have the capacity to carry up to 7,000 cars at a time. Wallenius Marine, the company responsible for Oceanbird (along with the Royal Institute of Technology, SSPA and the Swedish Transport Administration), believes in the future of zero-emissions shipping using wind as the main energy source.
