The VFD (Variable Frequency Drive) enables ship owners who want to slow steam with a shaft generator engaged to the main switch board but still maintain the proper voltage and frequency.
The VFD is a 4 quadrant state of the art full scale frequency converter that makes it possible to reduce the rpm on the main engine/s but still have the shaft generator connected to the main switch board and still maintain 50 or 60 Hz and a voltage level of  400 to 440 V respectively. The fuel save potential depending on service profile is 5-15%.
To explore the potential for your vessel please contact Projects and Retrofit Frederikshavn Denmark who will conduct an investigation to tell you about your fuel saving potential.
