Wind Resistance of Vessel's Superstructure Reduced by 10% -NYK and Tsuneishi Shipbuilding Jointly Develop New Energy-saving Technology, the MT-COWL -
July 20, 2011
July 6, 2011, NYK issued a news release titled "Wind Resistance of Vessel's Superstructure Reduced by 10% - NYK and Tsuneishi Shipbuilding Jointly Develop New Energy-saving Technology, the MT-COWL - " MTI has been in charge of research and development also various tests for the above project.
Nippon Yusen Kabushiki Kaisha (NYK Line; head office: Chiyoda-ku, Tokyo; president: Yasumi Kudo) and Tsuneishi Shipbuilding Co. Ltd. (head office: Fukuyama City, Hiroshima Prefecture; president: Takao Kawamoto) have jointly developed a new energy-saving technology called the MT-COWL, which reduces the wind resistance of the vessel’s superstructure. A wind tunnel test using a model showed that wind resistance was reduced by 10 percent.1 Applying this percentage to a 180,000 DWT bulk carrier, a reduction in CO2 emissions of 520 tons a year can be realized as a result of the enhanced fuel efficiency.
1Assumed to receive a wind speed of 17 knots (about 9 meters/second wind velocity) at an ordinary navigation speed of 15 knots. The relative wind velocity is calculated as 32 knots (about 17 meters/second wind velocity).
