POWERMATE is a development and qualification project for a totally new concept of underwater wet-mate electrical connection for transmission of high power produced by particular systems of offshore renewable energy, while reducing costs and improving reliability compared to current solutions.


  • Development of the connector and tool adapted to the needs of Marine Renewable Energy (medium / high voltage)
  • Development of installation procedures
  • Validation of the concept by hydrostatic testing, electrical testing and by pool tests in the sea.
