Abstract

In this research, objecting to the use of a lesser-known type of energy source, marine wave potential, the application of Sea-wave Slot-cone Generator (SSG) breakwater was investigated in the Caspian Sea. This study had two main objectives. 1) Investigation of the conditions of each of the selected waves in terms of speed factor in the face of this breakwater 2) Investigation of the scattering of different waves in the Bandar Anzali area on the southern shores of the Caspian Sea. About the first goal, eight waves with different characteristics were selected and applied. According to the simulation results, the wave with a height of 2.825 meters and speed of 6.56 m/s and waves with a height of 0.5 and 2.825 meters and speed of 13.02 m/s, with an efficiency of more than 50%, had the highest efficiency among the simulated waves. Nevertheless, in connection with the second goal, by examining the wave height diagram and the diagram of the specified wave period, most of the waves that occurred in the Bandar Anzali region in 100 days are close to the wave with a height of 0.5 meters and speed of 6.56 m/s with an efficiency of about 7%. It does not have an opinion, and the number of waves that occurred with favorable conditions is less than expected. Therefore, it was found that the use of SSG breakwater in Anzali port located on the southern shores of the Caspian Sea is not economically viable.
