The rotor sailing system is a new technology using wind power to drive a ship. The rotor sailing facility is installed on the two sides of the front deck of the 10,000-metric-ton large-scale deck transport vessel Hai Yang Shi You 226.

Consisting of a composite outer cylinder, a steel inner tower, a motor and a base, the facility is 18 meters tall and 4 meters in diameter, and weighs about 40 tons.
It has a maximum speed of 200 rpm and can work at a temperature of minus 25 degrees Celsius, making it capable of operation in iced-over sea areas at the world’s lowest latitudes.
The Hai Yang Shi You 226 vessel installed with the rotor sailing system consumes 12 percent less fuel according to tests.
