Norsepower completes installation of its rotor sail on the bulk carrier Yodohime

IINO Kaiun Kaisha, Ltd. (IINO LINES) and Electric Power Development Co., Ltd. (J-POWER) have successfully installed the world’s first Norsepower Rotor Sail™ on the bulk carrier Yodohime. This installation, completed in December 2024, marks a significant advancement in marine technology aimed at reducing fuel consumption and carbon emissions. The vessel’s first voyage with the new system was successfully completed this month, showcasing the potential of wind propulsion in modern shipping.

Advancements in Wind Propulsion Technology

The Norsepower Rotor Sail measures 24 meters in height and 4 meters in diameter. It is designed to harness wind energy to propel the vessel. The rotor sail is installed on the forecastle deck and utilizes advanced AI technology. This system automatically adjusts the rotation, direction, and speed of the sail based on real-time meteorological data, including wind direction and speed detected by onboard sensors.

The installation of the rotor sail is expected to reduce fuel consumption and CO₂ emissions by approximately 6-10%. This reduction is achieved through the Magnus effect, which generates thrust as wind interacts with the rotating cylindrical sail. The integration of this technology with a voyage optimization system enhances the vessel’s efficiency, making it a pioneering step in the shipping industry.

This is not the first time IINO LINES has embraced this technology. The company previously equipped the Very Large Gas Carrier (VLGC) Oceanus Aurora with a Norsepower Rotor Sail last November. IINO LINES is committed to promoting clean marine transport services and aims to achieve carbon neutrality as outlined in its mid-term management plan, “The Adventure to Our Sustainable Future.” J-POWER, for its part, is also focused on carbon neutrality, having set ambitious targets under its “BLUE MISSION 2050” initiative. Together, these companies are leading the charge toward sustainable shipping practices.
