Oceans cover more than 70% of the Earth's surface, and water waves are considered as unlimited sources of renewable energy. The use of fossil fuels may cause undesired challenges such as global warming and climate change in the nature. Advantages of renewable energy include low operational cost, environment friendliness, simple maintenance procedures, and non-polluting nature. In this study, an oscillating water column (OWC) system close to the onshore was investigated in water level for wave parameters which consist of different wave heights and wave periods. Efficient energy transformation is achieved by using air turbines. In this study, 20 experimental sets were carried out by a piston-type wave maker. The experimental results showed that the chamber geometry of the OWC, water depth, and wave parameters are most important factors in terms of achieving maximum wave power for energy harvesting.
