NYK and MHI Begin Experiments on Air-Lubrication System; 10% CO2 Reduction Expected by Lowering Seawater Resistance

Tokyo, Feb 24, 2010 - (JCN Newswire) - NYK and Mitsubishi Heavy Industries, Ltd. are to begin experiments on an air-lubrication system to reduce CO2 emissions during marine transport. Jointly developed by the two companies, the 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. The world's first permanent installation of the system using an air-blower is expected to reduce CO2 emissions by approximately 10 percent. The experiments will be conducted using module carriers* operated by an NYK Group company, NYK-Hinode Line, Ltd. (head office: Chiyoda-ku, Tokyo, Japan; president: Sumio Kinoshita) Construction of the vessels will be completed on March 31 and in late November 2010.

Amid a strong demand for effective environmental measures to counter global warming, NYK has proactively taken initiatives to reduce CO2 emissions throughout its marine transport, while Mitsubishi Heavy Industries has focused on the development of vessels that meet the needs for CO2 reduction as an important issue. Since the planning stage of the construction of the new module carriers, NYK-Hinode Line has been of the opinion that the air-lubrication system is physically optimal for installation on module-type vessels, and has decided to proceed with an actual installation.

Compared to other large vessels, a module carrier has a wide, shallow-draft hull that generates relatively little water pressure and accordingly minimizes the electric energy required by an air blower to supply air to the vessel's bottom. Moreover, due to the flat, wide bottom, the supplied air is considered to be readily retained under the vessel's bottom. For these reasons, it has been determined that experiments into the effectiveness of CO2 reduction can be verified using module carriers. This project is subsidized through Japan's Ministry of Land, Infrastructure, Transport and Tourism's "Support for Technology Development from Marine Vessels for Curtailing CO2" project for fiscal 2009 (announced on May 29, 2009),** and is also supported by ClassNK and the Nippon Foundation.

* Special heavy load carrier with roll-on, roll-off rampway to transport thousand-ton prefabricated structures of plant facilities to be installed on oil/gas development sites, or industrial locations.
** Announced on July 1, 2009. For more information, please see the company's website: www.nyk.com/english/release/31/NE_090701.html
