Advantages at a glance

Contribution to environmental protection

  • Reduction of the pollutant emission
  • Adherence to the statutory emission limits (emission limits according to ZKR (Zentralkommission für die Rheinschifffahrt, Central Commission for the Navigation of the Rhine and the EU)
    • Decrease of operational- and maintenance costs

      The highly efficient energy production- and converter system and securing constant operation of the energy producers in an optimum performance range ensure:

      • Reduction of the energy consumption by 10%
      • Savings in lubricant consumption by 30% and 50% for wear parts
      • Reduction of the maintenance costs by 50% by extension of maintenance intervals (speed and load conditions do not vary)

        Increase of operational safety and reliability

        Standard torque drives of 250, 750 or 1,500 HP are mechanically combined in one shafting. Depending on the performance requirements, a drive can act on a propeller alone or together with two or three other drives.

        The speed control is carried out via a frequency converter; the synchronization of the rotary fields is monitored and controlled.

          This is how the HTP™ system enables:

          • Redundancy also for ships with only one screw
          • Improvement of the maneuverability and the mobility of the ship
          • Immediate reaction of the screw in hazardous situations
            • Perspectives for ship building

              The modular concept of the systems enables a weight- and volume optimization in the stern. This leads to:

              • More flexibility for the design of the ship’s shape and thus the optimization of the propeller flow and an increase of the overall efficiency of up to 20%
              • Relocation of the aggregates for power generation to a better position (e.g. midship or bow) which means noise reduction and fire protection are easier to realize.
              • Increase of the cargo- or living space capacity in the rear area of cargo ships
              • If the engine room is located in the midship area, the draft can be decreased.
              • The rear area of passenger river vessels can be used more efficiently, because there are no emissions (noise of the diesel engines, vibration, oil- and combustion emissions) and no engine room ventilators (due to water-cooled torque engines)
