Norsepower completes installation of Rotor Sail on IINO LINES bulk carrier

A single Norsepower Rotor Sail™ has been successfully retrofitted onboard the 2016-built bulk carrier Yodohime belonging to Tokyo-based IINO LINES. The installation work was carried out at a dockyard in December 2024, and the first voyage after the installation was successfully completed this month.

The 24m x 4m Norsepower Rotor Sail is a wind propulsion system which was installed on the forecastle deck of the vessel. It utilises the latest AI technology 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 optimisation system, is expected to reduce fuel consumption and CO₂ emissions by approximately 6-10%.

his is the second vessel for IINO LINES to be equipped with Norsepower Rotor Sails, following the installation onboard the Very Large Gas Carrier (VLGC) Oceanus Aurora last November.
