Abstract

In the present work, the relationship between Romanian wave power and the distance to the shoreline is evaluated, by taking also into account the performances of some wave energy converters. Several reference sites located on northern, centre and southern part of this area were taken into account, the wave energy being assessed at 5 km, 15 km and 30 km from the shore. More important resources were noticed close to the Vama Veche (in south) were an average of 4.27 kW/m is reported offshore. As we go from shore to offshore, the wave variations may reach a maximum of 7.7% in the case of the Navodari site (centre), while a 3.3% is expected for Vama Veche. In the case of the wave generators, three types of systems (Seabased, Pelamis and Wave Dragon) were considered, that cover a rated capacity ranging from 15 kW to 7000 kW. For the Saint George s ite (north), the power production is insignificant being located close to zero, while in terms of the capacity factor a maximum of 0.12% may be expected from the Seabased system. The capacity factor significantly increases as we go to south, being reported during winter time values close to 3% for Pelamis system or 6% in the case of Seabased, respectively.
