As Nyk states, a wind tunnel test using a model showed that wind resistance was reduced by 10 %, i.e. applying this percentage to a 180,000 dwt bulk carrier, a reduction in CO2 emissions of 520 tons a year could be realized as a result of the enhanced fuel efficiency.
The innovative MT-COWL technology lowers wind resistance by attaching an add-on structure to the facades of the bridge wings and support pillars for the vessel’s superstructure, which creates corners with a slanted shape to reduce the effects of wind resistance. To reduce the wind resistance of the residential area, the two companies have developed various structural forms for the area.
