Wing-Sail Auxiliary Propulsion System for Ships

DNV GL has awarded an approval in principle (AIP) to Korea Shipbuilding and Offshore Engineering (KSOE) for a wing-sail auxiliary propulsion system for ships–the result of a joint research project between KSOE and SK Shipping.

The wing sail system will reduce fuel consumption by more than 6%, according to KSOE.

The wing sail design is 20 m wide, 50 m high, and installed vertically on both sides of the deck. It rotates its wings according to the direction and intensity of the wind to provide auxiliary propulsion to the ship. The wing can be lowered to 10 meters in height, making it flexible in case of bad weather or when passing under a bridge.
