Sweden has the largest wind powered ship

In Sweden, the Oceanbird liner project was presented – this is the largest marine vehicle that practically does not emit carbon and other harmful substances. The engines are only used for emergency situations.

The transatlantic liner Oceanbird is being designed by the Swedish shipbuilder Wallenius Marine, and the company will also receive funding from the government and several research centers. The vessel can accommodate 7 thousand cars. The vehicle, 200 meters long, will look completely different from other sea vessels. Five “wing sails” were introduced into its hull, each of them being 80 m high. They can turn 360 degrees without touching each other, the sails can be removed to pass under a bridge or to wait out bad weather.

The sails, which will be made of steel and composite materials, have been made large enough to generate enough power for a 35,000-ton vessel (fully loaded). In order to take into account the atmospheric conditions and create housing, the researchers installed several sensors at an altitude of 200 m above sea level. “All of this information helped us design an efficient wing and hull system capable of making the most of wind power,” the researchers note.

The authorities of many countries are demanding the reduction of greenhouse gases from the shipping industry In 2018, shipping accounted for 2.89% of global human-induced greenhouse gas emissions, according to the International Maritime Organization (IMO), the UN body that regulates global shipping. In the same year, the IMO introduced a mandatory 50% reduction in total annual greenhouse gas emissions by 2050.

The new vessel is designed to even exceed those numbers – it emits 90% less carbon than any other marine transport vessel. However, so far scientists cannot completely get rid of harmful emissions – the engines are running in the vehicle, which is needed for maneuvering in ports and during emergencies.
