This feasibility study will investigate the application of a direct drive, contra‐rotating generator to different WEC architectures.

In order to establish the impact this step change technology could have on reducing plant capital costs through:

  • weight savings;
  • reduction of the station keeping/ hold down capacity;
  • reducing operational and maintenance costs through the elimination of generally complex power transfer and take‐off systems;
  • improvements to device performance and efficiency through the elimination of the power conversion and transfer system

The project seeks to study these factors and examine how application of the contra rotating generator could ultimately reduce the cost of energy from WECs.
