TRL 5/6: System Integration and Technology Laboratory Demonstration
Technology Description he Rotech Tidal Turbine (RTT) is a bi-directional horizontal axis turbine housed in a symmetrical venturi duct. The Venturi duct draws the existing ocean currents into the RTT in order to capture and convert energy into electricity. Use of a gravity foundation will allow the RTT to be deployed quickly with little or no seabed preparation at depths in excess of 40 meters. This gives the RTT a distinct advantage over most of its competitors and opens up a potential energy resource that is five times the size of that available to companies using pile foundations.

Mooring Configuration The RTT is gravity based structure and there will be no requirement for device moorings
Optimum Marine/Riverline Conditions The device is capable of operating across a wide range of tidal and barrier applications All present modelling and device details are scaled for a tidal speed of 7 knots although we are currently designing for sites at 5knots and 11knots
