Ship propulsion system

electrically-powered

UNIQUE EFFICIENCY Great advancement in efficiencies in hull, propeller and motor makes the Brunvoll CRP-PM a unique system based on a combination of known technologies. LOW EMISSIONS The high efficiency gives considerable fuel saving and reduced emissions of CO2, NOx and SOx. LESS COMPONENTS Fixed pitch propellers and short shaftline directly connected to slow speed permanent magnet motors gives a system with easy installation and low maintenance cost. ENVIRONMENTALLY FRIENDLY SYSTEMS Better noise output with each propeller having a lighter load. Ultra quiet PM motors also make for a comfortable environment within the vessel. MORE THAN 20% HIGHER EFFICIENCY IN TRANSIT MODE Based on calculations from model test simulations of Brunvoll CRP-PM system versus Azimuth CRP twin screw system. ROBUST AND PROTECTED Fixed pitch propeller system with few movable parts. The propeller is protected behind the center skeg far from the ship side, while the propeller tip is well above the baseline and further protected by a solepiece.
