The vessel Soyo, jointly developed with Oshima Shipbuilding Co, features a main engine scavenging air bypass that uses bubbles to reduce the frictional resistance between the ship's bottom and the seawater.
Soyo, a third vessel equipped with such a system, will be the world's first vessel for overseas transport to have an air-lubrication system permanently installed, NYK claimed.
Sea trials showed a 4% reduction in carbon dioxide during deep drafts and about 8% reduction in shallow drafts.
“The NYK Group will continue to encourage initiatives that address climate change by striving to install this system on other types of vessels,” NYK said.
