Abstract
In this paper, the experimental test of five 1:20 scale pitching floating Wave Energy Converters (WEC) arranged in two different array layouts is presented and described. A particular attention is given to the challenging experimental setup and the first analysis of the hydrodynamic interaction occurring among the different bodies. The Response Amplitude Operators (RAO) of the array WECs are compared against the dynamics of the isolated floater test, in order to evaluate the bodies’ interaction and thus the devices performances. The regular waves are performed for two wave steepness 1:50 and 1:35. A free decay analysis is conducted in order to identify the natural frequency, linear and quadratic damping term for the pitch Degree of Freedom (DoF).
