Wallenius Marine introduces wind powered car carrier

The sailing cargo vessel Oceanbird will leave 90% less emissions than today’s vessels, which shows that the maritime industry can bring about major change and that zero-emission shipping is possible. The design will be ready for orders in 2021 and we are aiming for a launch in 2024.

Called Oceanbird, the concept is for a new class of vessel with the are calling a “pure car and truck carrier” or PCTC, with a capacity to carry 7,000 cars. The concept design is over 650 feet in length and would have a 32,000-ton displacement. The height over the waterline is nearly 350 feet. Primarily powered by the wind the vessel will have an estimated speed of 10 knots permitting it to cross the Atlantic in approximately 12 days or 50 percent longer than today’s crossing that takes about eight days.
The futuristic sails are like airplane wigs using the same level of aerodynamic technology. They are also designed to telescope from a minimum height of 150 above the waterline to permit the ship to pass into harbors to 200 feet and a maximum of 262 feet permitting the ship to operate at optimal conditions or reef the sails in high wind conditions. At maximum height, the wing sails would be twice the height of today’s largest conventional sailing vessels
The rigging is made of steel and composite materials and turns 360 degrees to catch the wind in an optimal way. To be able to get in and out of harbors, and to meet international safety requirements, Oceanbird would also be equipped with an auxiliary engine.
