Flow-optimized propellers can reduce fuel consumption by up to ten tons per day To improve ships manoeuvrability and energy efficiency also the propellers play a big role. Worldwide leading manufacturer of ship propellers is the Metallguss GmbH (MMG) in Waren, Germany. The company produces also propellers with six blades with a diameter of up to 9,30 meters and a weight of 97 tons for example for container ships with a load capacity of 9.400 TEUs. The propulsion power of such 286 meters long and 48.20 meters ship with a draft of 14.50 meters is of one diesel engine with an output of max 52.290 kW. With this a speed of 22.3 kn is reached. Propellers of the "AIDAstella" have a diameter of 5.2 meters and weigh each 12.8 tons The propeller is pretty much decisive to transfer as much as possible of the engine energy into propulsion energy. With particular large diameters and very specific blade geometry an efficiency gain of three to four percent can be reached – with following posit... [More]
