Workshop II Long Distance Subsea Power Transmission

Thursday, 25. Mar 2010

New Subsea Installations are often remotely located and thus have to be tied back over long distances to supply control signals and power. Especially the operation of variable speed electric motors poses different challenges. Since there are no submersible DC-Motors available and reliable subsea converters are still in development, AC has to be transmitted over long distances although the losses in the cable are much higher than with DC. In addition the quality of the sinus signal is affected too, and the power system reacts slower to sudden changes of the motor load. These challenges require new solutions that shall be discussed in this workshop.
