In a bold step towards greener shipping, a Swedish shipbuilder, Wallenius Marine, has teamed up with the Swedish government and research institutions to design a transatlantic car carrier called Oceanbird. What sets this vessel apart is its towering “wing sails” that reach a staggering height of 260 feet, making them the tallest ship sails ever constructed. With the capacity to carry 7,000 vehicles, Oceanbird aims to drastically reduce emissions, emitting 90% less CO2 than conventional car carriers. While the ship’s top speed will be slower than traditional carriers, taking around 12 days to cross the Atlantic, the response from manufacturers has been positive. With plans to launch the full-size version in 2024, it seems that wind power is blowing new life into the maritime industry’s quest for sustainability.
