Abstract (EN): This paper deals with the numerical modelling of an innovative technology for harnessing wave energy and its power take-off system. The investigated wave energy converter is CECO, a device based on the principles of oscillating bodies that is being developed at the Faculty of Engineering of the University of Porto, Portugal. The particularity of this concept lies on the relative motion between a floating part and a supporting one, which is restricted to translations along an inclined direction. First, the wave energy converter is modelled in the frequency domain by means of a panel model that is based on the boundary element method. Once obtained the frequency-dependent hydrodynamic coefficients of the floating part, the dynamic equation of motion is solved in the time domain by including, not only the hydrodynamic forces, but also the force of the power take-off system. The results prove the ability of the numerical modelling approach to simulate the behavior of the device and provide insight into its performance.
