Germany: Siemens Receives Order to Provide Diesel-Electric Propulsion Systems for Italian Coast Guard

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.

The Naples-based shipyard Cantieri Navali Megaride has commissioned Siemens to equip an offshore supply vessel for the Italian coast guard with the diesel-electric EcoProp hybrid propulsion system. The Siemens propulsion system includes two main gear units, electric propulsion motors and the hybrid propulsion control system. The standardized modules require very little space on board. Siemens will be responsible for the project management, engineering and commissioning of the complete diesel-electric propulsion system. The ship design was planned by the Italian project office Errenavi in Rome, Italy.

When a ship is electrically powered in the lower load range, efficiency of the propulsion system is increased, which in turn saves substantial amounts of energy and fuel. In fact, often only about 10 percent of the main propulsion power is required from the electric drive. As a result, hybrid propulsion systems offer substantial potential for increasing energy efficiency, particularly for ships with frequently changing drive modes and running speeds. The correct propulsion mode for the particular task or purpose can be selected with a modern hybrid control system: In diesel mode, the power comes from the diesel engines, which drive the electric machine as a generator for the on-board power supply system while the ship is at sea. In electric mode, the same machines that provide on-board power propel the ship, but at low speeds.

This enables the main propulsion engines to run at optimum utilization in diesel mode, or to be switched off completely in the low operating profile when the ship is sailing at low speed. Running the diesel engines continually within their optimum load range not only reduces fuel consumption and emissions but also lengthens service life. In addition, longer service intervals for the propulsion diesel engines also help save money. Using electric motors in combination with diesel engines substantially increases the availability of the overall system. Benefits include greater flexibility and safety in everyday operation as well as during difficult maneuvers in harbors and bays, and when anchoring.

9th Annual Coasts and Marine Structures 2017 Conference

Discover Best Practise Strategies for Design, Planning, Construction and Asset Management

To remain competitive, Australian port operators must plan, design, manage and maintain their assets more creatively and proactively to meet future demands and drive profitability.

With this in mind, the Coast and Marine Structures Summit 2017 will focus on key considerations relevant to ensuring your existing assets are maximised and prepared to accommodate bigger vessels.

Hear from 20+ global experts including Maritime/Coastal Engineers, Contractors, Port Authorities and more, including GHD (USA), Indonesian Port Corporation (Asia), G-Group Consulting (New Zealand), Ausenco (Australia), Port Authority NSW (Australia), to name a few.

By attending this 2-day conference, you’ll learn about:

– Innovative planning and design of ports to create efficiencies that drive profit
– Best practice asset management strategies and new PIANC design principles for bulk terminals
– Proactive asset management and maintenance to improve durability and maximise and extend asset lifecycles
– Alternative material and protection techniques trialled and tested in the US and Europe
– Strategies to shift organisational culture and mindset from asset management to asset maintenance
– How you can leverage technology to increase the efficiency of your marine structures
– Case studies on retrofitting, expanding and upgrading your ports in cost-effective ways
