width and 9 m in height. Their study was presented in December
2023 in the Journal of Marine Science & Engineering.
When utilizing magnetic bearings and the principle of levitation
for rotor sail operation, careful consideration is essential for loads
imposed on the rotor sail due to wind, explain the researchers.
Particularly, controlling sudden external load changes is crucial
to preventing collisions within the rotating structure and internal
components of the rotor sail. Additionally, the weight of the rotor
should be reduced to a minimum to minimize power consumption
associated with the application of magnetic bearings and the
principle of magnetic levitation.
RoRo fleet will carry aircraft components for Airbus on transatlantic
voyages
By 2030, for the transatlantic route, the new fleet will generate
approximately 50% fewer CO2 emissions compared to 2023.
The rotor sails will feature the brand new patented Norsepower
Sentient Control, a real-time force measurement, control and
savings reporting system that enables each rotor to be controlled
individually.
" This fleet-wide deal is a game changer for the whole auxiliary
wind propulsion industry, " commented Riski. " Firstly, it is the
biggest deal ever made in the mechanical sails market - and,
in a world first, it includes our brand new Norsepower Sentient
Control tool. "
Considering the variable wind conditions in coastal areas, a new
rotor sail concept utilizing magnetic bearings and the principle of
magnetic levitation was proposed, allowing for easy speed control
while reducing noise and vibration. Assuming operation on a
demonstration ship of approximately 30 m in length and 100 kW
power in Korean coastal areas, the prototype could potentially
provide an auxiliary thrust of around up to 19 kW.
Subsequent research will analyze the relationship between the
power required for the prototype's operation and the resulting
propulsion power to assess its economic feasibility. Further
plans include the construction of the demonstration ship and the
prototype for sea trials in Korean coastal areas, aiming to verify
the operability of the rotor sail utilizing magnetic bearings and the
principle of magnetic levitation.

Modern bulk carrier will be outfitted with three Norsepower Rotor
Sails
Also in February, Oldendorff and Norsepower announced an
agreement to use its rotor sails on a modern bulk carrier, the
vessel Dietrich Oldendorff, to be outfitted with three 24m x 4m
Norsepower Rotor Sails by mid-2024, helping propel it on a North
Pacific trade route to Asia. Oldendorff is a legendary, familyowned
shipping company with over 100 years operating in the
industry and around 700 vessels on the water today.
Research in Korea for rotor sails in coastal waters utilizing
magnetic bearings
In Korea, researchers are investigating the use of magnetic
levitation and magnetic bearing technology to equip rotor sails
for coastal waters where the wind is more variable than on the
high seas. The Alternative Fuels & Power System Research
Division, Korea Research Institute of Ships & Ocean Engineering
in Daejon is developing a prototype of a scale model for coastal
operation performance evaluation with dimensions of 1.5 m in
