Power Management , Fuel Economy , Redundancy and Less Noise Are Key Features. For valid reasons, in recent years diesel-electric propulsion has gained remarkable interest over traditional propulsion within commercial shipping and yachting. Propulsion with the best possible fuel economy, lowest possible emissions, more flexible redundancy arrangements, considerable lower noise and vibration levels, diesel-electric propulsion offers significant economical, environmental and technical advantages. By eliminating the need for a traditional , mechanical gearbox , operating performances are improved. Every single diesel-generator set is connected to its own generator inverter.
