Kongsberg Maritime has successfully adapted a propeller concept used in naval applications, aiming to provide operational and environmental benefits to commercial shipping customers. By deploying such a technology can significantly reduce cavitation-induced noise and erosion risk.
Kongsberg Blade Air Emission technology is now being applied to commercial ship propellers to limit the effect of underwater radiated noise on marine life. The Blade Air Emission concept applies the results of research...
