Abstract
SENDEKIA has invented and patented a unique conversion system consisting on a water turbine working with an oscillating water column. SDK Wave Turbine, Sendekia’s patented technology is able to take off power from hydraulic bidirectional oscillating movement. This means that we are capable of taking off power both on inflow and outflow. That’s because the pitch of the blades changes as flow changes, from positive to negative, always propelling in the same direction, like a whale’s tail.
SDK Wave Turbine can be install floating or fixed in a breakwater. The buoy is deployed with a simple four-wire mooring attached to an anchoring weight on the seabed. At the bottom of the buoy there is an opening that allows flow between the oscillating water column chamber and the sea. The turbine is located there.
In the north of Spain exists a similar Infrastructure but with less wave generation capabilities. The buoy can take advantage from waves between 1 and 7 meters, and periods range from 6 to 20 seconds. SENDEKIA is looking for internationalize the technology by university collaboration and partnerships with other companies.
With the results achieved with MARINET support Sendekia will be able to perform the detailed engineering to build the first prototype for testing in the sea.
