NBS (New Blade Section) propeller, developed by Sumitomo Heavy Industries Marine & Engineering Co.,Ltd. is not only high propulsive performance propeller but also compact propeller. The diameter of the NBS propeller is approximately 5% smaller, and the weight is approximately 20% smaller, than conventional propellers that are designed under the same conditions. Advantages of NBS propeller are;1) Reduction of fuel oil consumption and CO2 emission in the navigation, 2) Reduction of hull vibration, 3) Increase of design flexibility and the value of the vessel and 4) Contribution to the cost and material resources saving. The high reliability of the NBS propeller has been proven through its installation in more than 200 vessels since 1999.
