Abstract
Abstract Ocean waves are considered as a potential unharnessed renewable resource being 800 times denser than wind. India has a wide coastal area of nearly 7500 km, providing a huge potential for harnessing ocean wave energy. The article aims to present the parametric optimization of a point absorber wave energy converter (PAWEC) for a location near Ennore port of India. Indian offshore condition such as significant wave height, period, and amplitude was reviewed for their minimum, maximum, and average values for several years. Hydrodynamic coefficients such as Froude-Krylov force, radiation damping, added mass, diffraction, excitation and response amplitude operator are optimized through geometric optimization of PAWEC’s float. In hydrodynamic response analysis, only heaving motion is considered and all motion is neglected for the study. Regular wave is only considered for this study. Output parameters such as structure velocity and structure response are studied for the mentioned geometry. Power-take-off (PTO) device is simulated for maximum efficiency and the float velocity response is observed. Monthly variation in the mean absorbed power and efficiency of Point absorber is calculated with respect to ocean power.
