DNV awards API to DSME for new rotor sail system for ultra-large vessels

DNV awards API to DSME for new rotor sail system for ultra-large vessels
Daewoo Shipbuilding & Marine Engineering (DSME) announced that DNV has awarded an Approval in Principle (AIP) for the new DSME Rotor Sail System, designed for ultra-large crude oil carriers and LNG carriers.
At the Daewoo Shipbuilding & Marine Engineering R&D Center, a certification ceremony for the Rotor Sail System was held in the presence of related officials including Choi Dong-gyu (right), the president of the Central Research Institute.
A rotor sail is a tall rotating cylindrical column on the deck of a ship that provides propulsion from the wind. Rotor sail technology is based on the Magnus effect. When wind meets the spinning Rotor Sail, the air flow accelerates on one side of the Rotor Sail and decelerates on the opposite side of the Rotor Sail. The change in the speed of air flow results in a pressure difference, which creates a lift force that is perpendicular to the wind flow direction. (Earlier post.)
