Dynamic Cables systems for floating Off-shore Energy converters

Today Off-shore Wind Farms are developed on shallow water with turbines fixed on the sea bed. Continental platform is deeper than 45m at most places in the world, then floating platform will be necessary.

Dynamic Cables systems for floating Off-shore Energy converters

Floating platforms will be arranged in radial arrays delivering energy to a Hub (typical 33 kV) In order to be ready for this emerging market we have already developed:

• High-dynamic off-shore cables to ensure the maximum life time to ensure that cable will perform as expected.

• Hybrid (Power + Optical) Medium Voltage Wet Mateable connectors.

• Automated connection system with a proprietary ROV.
