CO2 savings of the Torque Marine Systems compared to conventional systems
Advantages at a glance
Contribution to environmental protection
Reduction of pollutant emissions
Compliance with the statutory emission limits (emission limits according to CCNR, Central Commission for the Navigation of the Rhine, Stage 2, and the EU)
Reduction in operating and maintenance costs
The highly efficient energy generation and converter system and the guarantee that the energy generators are constantly operating in the optimum power range:
Reduction of energy consumption by 10
Savings of 30 % in lubricating oil consumption and 50 % in wear parts
Reduce maintenance costs by 50 % by extending maintenance intervals as a result of constant speed and load conditions
Increased operational reliability and failure safety
Standard torque drives of e.g. 250, 750 or 1500 HP are mechanically coupled in a shaft train. Depending on the power requirement, such a drive can act alone or through 2 or 3 drives together on one propeller.
The speed is controlled by a frequency converter; the synchronization of the rotating fields is monitored and controlled.
The HTP® system makes this possible:
Redundancy even for ships with only one propeller
Improving the maneuverability and agility of the ship
Immediate reaction of the screw in dangerous situations
Prospects for shipbuilding
The modular design of the systems enables weight and volume optimization in the aft section. The result:
More flexibility in the design of the ship shape and thus optimization of the propeller inflow and increase in overall efficiency by up to 20
Relocation of the gensets for the power generators and rearrangement to a more suitable location (e.g. midship or forecastle), where noise insulation and fire protection are easier to realize.
Increasing the loading and/or living space capacity in the stern area of cargo ships
If the engine room is installed in the midship area, draught can be saved as a result of ballast.
On river passenger ships, the stern area can be used more effectively for the passenger area due to the elimination of emissions (noise from diesel engines, vibration, oil and fuel emissions) and the elimination of engine room fans (due to water-cooled torque engines).
