Finnish wind propulsion systems provider Norsepower has completed the installation of one rotor sail onboard the bulk carrier Yodohime.
The company announced the installation of the rotor sail onboard the Yodohime (completed in February 2016), which was decided by IINO Kaiun Kaisha, Ltd. and Electric Power Development Co., Ltd., and manufactured by Norsepower Oy Ltd.
The installation work was carried out at a dockyard in December 2024, and the vessel equipped with the rotor sail completed its first voyage this month.
The 24m x 4m rotor sail is a wind propulsion system which was installed on the forecastle deck of the vessel.
It utilizes the latest AI technology, the company claims, to automatically control the rotation, direction, and speed of the rotor sail using real-time meteorological information, such as wind direction and wind speed, detected by sensors.
“The Magnus effect generated when wind meets the rotating cylindrical sail produces a powerful thrust which, in combination with the voyage optimization system, is expected to reduce fuel consumption and CO₂ emissions by approximately 6-10%,” Norsepower said in its statement on Wednesday.
