Many technologies to absorb wave energy is provided and there are different ways to optimize the efficiency of wave energy converters. In this study, the analysis of mooring system and its impact on the dynamics of a point absorber wave energy converter was considered.
Energy absorption from ocean waves by two-body point absorber converters depends on the relative displacement between the buoy and submerged body of a point absorber converter in the direction of heave. For this purpose, in wave energy converter is used a three-point mooring system with heave plate, Conventionally. In this paper, two types of mooring systems for a point absorber converter are considered. Then, the dynamic of two models is analyzed in the regular wave. Hydrodynamic Forces and coefficients are calculated by the discretization of boundary integral equations in the wave scattering and radiation problem.
The responses of the submerged body and buoy to regular wave were investigated. The results are validated with the available results. Extracted energy is calculated via the value difference between the relative displacement of the buoy and submerged body. The obtained results showed the significant contribution of the tension mooring system into enhanced the value of relative motion and the efficiency of the converter
