The Overtopping Breakwater for Energy Conversion (OBREC) is a typology of overtopping wave energy converter integrated into a traditional rubble mound breakwater. The OBREC has the same functions as the traditional structures with the added value of energy production. This paper aims to compare between different designs of OBREC and choose the optimum to be applied on an Armored rubble mound breakwater located in San Stefano Alexandria. By applying mathematical model, results show that the yearly power production after applying OBREC is 49 MWh generated from mean wave power at that area is about 196 MWh/year, and with OBREC mean efficiency about 20 %.
