Norwegian Orders Rolls-Royce Propulsion Upgrade

Norwegian Cruise Line has selected a Rolls-Royce permanent magnet tunnel thruster to upgrade the propulsion package onboard cruise vessel Norwegian Epic. According to Rolls-Royce, the permanent magnet tunnel thruster offers numerous advantages over traditional tunnel thrusters including reduction in noise and vibration, an increase in power output of around 25% from the same size propeller, and is removable underwater eliminating the need for dry docking.
