摘要：
The study aims to compare two different power take-off systems installed in a dual body wave energy converter, first the power take-off in between the floater and the submerged body, and second in between the submerged body and the sea bottom. It is intended to prove that the second is more efficient. The analysis is carried out for three WEC's with different bodies, cylinder-sphere, cylinder-cylinder, and sphere-sphere, for the floater and submerged body. The analysis begins by modeling the bodies in NEMOH, a software that calculates hydrodynamical coefficients. After, a dynamical model is created in the frequency domain to calculate power absorbed and efficiency in regular and irregular waves for all geometries with both the first and the second PTO'sconfiguration. The final analysis is comparing the efficiency in irregular waves for the first PTO configuration against the second, it shows that the second configuration has an improvement of 11%.
