China’s first independently developed rotor ship sail was put into use
China National Offshore Oil Corporation (CNOOC) announced that Asia’s first marine wind rotor propulsion system independently developed and manufactured has been successfully put into use. This is a breakthrough in China’s naval power technology and the green and low-carbon development of its maritime industry.
The rotor sail system is a new technology that uses wind energy to propel ships. The motor drives the rotor to rotate, generating thrust perpendicular to the direction of the incoming wind.
The rotary sail system put into operation this time is installed on both sides of the foredeck of the 10,000 ton large-scale deck transport vessel “Offshore Oil 226”. The rotating sail is notably composed of an outer cylinder made of composite materials, an inner steel tower, a motor and a base. It has a design height of 18 meters, a diameter of 4 meters, a single weight of 40 tons and a maximum speed of 200 rpm.It can work in minus 25 degree Celsius environment and is applicable to icy sea areas at the lowest latitudes in the world.
China’s coastal routes are very rich in wind resources. The average wind force on offshore routes reaches level 4, which has broad application prospects.
