NIPPON Yusen Kabushiki Kaisha (NYK Line) has gained the highest award at the 2013 Nikkei Global Environmental Technology Awards in recognition of the NYK Group's use of an energy-saving air-lubrication system for vessels.
The system was developed with Saikai City, Nagasaki Prefecture-based Oshima Shipbuilding Co and Tokyo's Monohakobi Technology Institute (MTI), an NYK Group company.
The awarded air-lubrication system effectively reduces CO2 emissions by use of bubbles generated by air released from the bottom of the vessel to lessen the frictional resistance between a vessel's bottom and the seawater.
In 2010 a new air-lubrication system that features a blower that provides air to the vessel bottom, thus reducing friction between the vessel bottom and the sea, was co-developed with Mitsubishi Heavy Industries Ltd and installed on two NYK Group module carriers.
A system using the vessel's scavenging air was additionally developed and installed on a new coal carrier at Oshima Shipbuilding in 2012, thus demonstrating the viability of a system for large vessels having deep drafts.
In fact, a CO2 reduction of about four per cent during sea passages at deep drafts, and about eight per cent at shallow drafts, has been confirmed.
