Hyundai Heavy Receives Rotor Sail Approval


Major South Korean shipyard Hyundai Heavy Industries Co. had acquired design approval for Hi-Rotor, a rotor sail that is a form of wind-assisted propulsion for ships, from the Korean Register of Shipping (KR) for the first time in the domestic shipbuilding industry, says an article published The Korea Bizwire.

Cylinder-shaped structure

A rotor sail is a cylinder-shaped structure installed on the deck of a ship.

It is a kind of mast that reduces fuel consumption and carbon emissions by using wind to create additional propulsion power.

Reducing fuel consumption

If a rotor sail that rotates using an electric motor meets the wind flowing around the ship, a pressure gap is created around the rotor sail that creates a propulsion force.

When mounted on a ship, a rotor sail can contribute to reducing fuel consumption and carbon emissions by about 6 to 8 percent.

Risk management company

Hyundai Heavy acquired a basic certificate for its in-house developed Hi-Rotor in December 2020 from the KR, a South Korean ship quality assurance and risk management company.

Hi-Rotor uses a reduction gear method for the mechanism that connects the electric motor with the rotor for improved safety compared to the belt-type method of existing commercial products.
