heal.abstract	The present paper is dealing with the numerical prediction of the performance characteristics of an array of five wave energy heaving converters placed in front of a reflecting vertical breakwater. At a first stage, the appropriate mechanical system modeling is presented. Detailed insight into the system's kinematical and power production characteristics is given. In the second part, the analytical method used for the evaluation of the hydrodynamic characteristics of the cylindrical floats moving in front of the breakwater is outlined, supplemented with representative numerical results concerning the hydrodynamic parameters in frequency and in time domain. Hydrodynamic interactions among the floats and the adjacent breakwater are exactly taken into account using the method of images. The third part of the paper is devoted to the numerical integration algorithm for solving the coupled non-liner equations of motion taking into account both linear and non-linear couplings with the power take-off mechanism.
