MHI Desings Environmentally Friendly Container Vessel to Reduce CO2 Emissions by 35% - Hellenic Shipping News Worldwide

Posted October 15, 2010 - Hellenic Shipping News Worldwide

Mitsubishi Heavy Industries, Ltd. (MHI) has completed the conceptual design of the "MALS-14000CS," container vessel that will contribute to the prevention of global warming. The MALS-14000CS adopts the company's proprietary Mitsubishi Air Lubrication System (MALS), which reduces frictional resistance between the vessel hull and seawater using air bubbles at the vessel bottom produced by air. Incorporating the MALS, along with today's most advanced high-efficiency ship hull design and propulsion system, the vessel will be capable of reducing emissions of carbon dioxide (CO2), a major greenhouse gas (GHG), by 35% compared with container carriers of conventional design.
MHI has already installed the MALS on the "YAMATAI," a module carrier operated by NYK-Hinode Line, Ltd., a subsidiary of Nippon Yusen Kaisha (NYK Line), and is verifying its CO2 reduction efficiency, expecting approximately 10% cut. This marked the world's first application of an air-blow type ALS system on an ocean-going vessel for permanent use; the MALS-14000CS signifies the second application of MALS technology.
The MALS-14000CS is designed to realize a 10% reduction in CO2 emissions through the MALS. The ship design, featuring a new high-performance hull form, places the bridge relatively forward, exhaust funnels at the stern, and additional container space under the accommodation quarter. The new ship design, providing increased container carrying capacity, coupled with a two-engine, two-shaft propulsion system, enables a reduction in CO2 emissions by 24%. Combined with another 5% reduction enabled by the electronically controlled diesel engine and waste heat recovery system, the MALS-14000CS achieves an overall 35% cut in CO2 emissions*4. The MALS-14000CS is designed to be further environmentally friendly through installation of a SOx scrubber to remove sulfur oxide (SOx) from flue gas and a ballast water treatment system.
