SENER has been developing technology for more than 2 years. During this time SENER has requested 3 patents in relation with the technology and has done 3 tank testing campaigns: first of a fixed OWC chamber in Universidad Politecnica de Madrid in order to calibrate the numerical model of the water column (damping), second testing of a fixed and floating device in a flume in Cantabria and third tank testing of the fixed and floating device in the CCOB, also in Cantabria, both with the aim of analyzing the performances of the device, as well as calibrate the numerical model (hydrodynamic coefficients). In summary, the aim of these tests was the proof of concept and the calibration of the "in-house" software that SENER is developing (SENERWave). The results were very good for the fixed device. Now, we need to understand the effects of the bathymetry of the seabed in the performances of the fixed device. Therefore, it was necessary to access a facility where it is possible to change the slope of the seabed, as well as permitting the test of a 1:25 scale device in the basin, in terms of depth and waves.
