The latest order placed with Siemens Marine Solutions proves that diesel-electric propulsion systems are suitable not only for large merchant and naval vessels but also for small ships. The Italian shipyard Cantieri Navali Megaride has commissioned the Siemens unit to equip a 65-meter-long offshore supply vessel from the Italian coast guard with the Siship EcoProp hybrid propulsion system. The innovative propulsion solution has been especially developed to meet the requirements of smaller ships. Diesel engines are combined with innovative, electric drive components, each of which has an output of 180 kilowatts per shaft. An added benefit of the system is that it can be installed in tight spaces. Various modes of operation optimize utilization of the diesel engines, resulting in lower fuel and energy consumption as well as CO2 emissions. Other advantages over conventional diesel engines include a greater cruising range, higher reliability and less noise pollution. The EcoProp system is scheduled to be commissioned at the beginning of 2012.
