The Helsinki-headquartered manufacturer of auxiliary wind propulsion has fitted the dry bulker, on commission by IINO LINES and J-Power, with one 24-metre-tall and 4-in-diameter Rotor Sail.
The sail, installed on the forecastle deck, utilises artificial intelligence to automatically control the rotation, direction, and speed of the rotor, using real-time meteorological information from sensors, such as wind direction and speed.
In combination with a voyage optimisation system, Yodohime's Rotor Sail is expected to reduce fuel consumption and CO2 emissions by approximately 6-10%.
It is IINO LINES' second Norsepower retrofit (the very large gas carrier Oceanus Aurora received her two 20-by-4 sails in November 2024) and J-Power's first.
