This research includes designing and executing of an applied model for converting the energy of the offshore sea waves into electrical power. The model runs according to oscillating water column system (OWC) using air turbine, which rotates by the air pressure generated by the sea waves within the energy chamber. The article studies the effect of technological changes on the efficiency of the model and subsequently the number of its turbine's rotation, within the wave parameters under the Syrian coast conditions. Results in form of clear curves and diagrams will be discussed. They will also be analyzed and considered to achieve a suitable suggestion that can improve the system in the future.
