Cargo ships carry around 90% of global trade — roughly 11 billion tons of goods each year — and contribute mightily to global greenhouse-gas emissions. But one Swedish company is looking to make shipping a bit more sustainable with a new breed of emission-free vessels. 

Shipbuilder Wallenius Marine teamed up with Stockholm’s Royal Institute of Technology, maritime consultancy SSPA, and the Swedish Transportation Administration to design a new type of cargo ship that’s far more ecologically friendly than the diesel-powered vessels on the seas today. The result of that partnership is Oceanbird, a cargo-ship concept that’s pulled along by gigantic wing-like sails. 

Wallenius claims Oceanbird will be able to carry 7,000 cars and be 90% more efficient than other ocean-going vessels. The trade-off, however, is that Oceanbird will take around 12 days to cross the Atlantic, whereas traditional ships currently make the journey in about eight.

Oceanbird gets its power from five 262-foot wings, which are made from metal and composite. They’re twice the height of the sails on the biggest sailing ships today, Wallenius says.

In its current design, the ship will be 656 feet long and and 131 feet wide. That would make it the largest sailing vessel when completed, according to Wallenius.

The sails spin 360 degrees to catch the wind and can retract by 75% for stormy conditions or to pass under a bridge.

Plus, Oceanbird will have engines for emergencies and for easier maneuvering in ports.

Oceanbird is designed to carry 7,000 cars, but Wallenius plans to apply the same technology to other types of ships, like cruise ships.

Wallenius worked on the design for several years, and built a seven-meter model to be tested this fall.

Oceanbird will be ready to order by the end of next year, Wallenius said, and the first vessel will be delivered at the end of 2024.
