NYK Line Air-lubrication System Reduces CO2 Emissions by 6%.
The air-lubrication system effectively reduces the frictional resistance between a vessel's bottom and the seawater by means of bubbles generated by supplying air to the vessel's bottom. In fact, this was the world's first permanent installation of a system using an air-blower.
The system was installed on the two vessels when they were built, and the experiments were conducted duringactual sea passage. This project has been subsidized through Japan's Ministry of Land, Infrastructure, Transport and Tourism's "Support for Technology Development from Marine Vessels for Curtailing CO2" project from fiscal 2009, and has also been supported by the ship classification society Nippon Kaiji Kyokai (ClassNK).
The experiments were designed to verify fuel reduction, examine the behavior of the air bubbles supplied to the vessel bottom under various operational and sea conditions, confirm the relationship between the amount of air supplied and its effect, and validate CO2 reduction.
The project has been completed, but NYK, MTI, and NYK-Hinode Line will continue to conduct performance analyses on actual vessels and device reviews during dry docks to achieve optimal operation. At the same time, the NYK Group will strive to install the system on other types of vessels for greater energy-saving operations.
