Analysis and simulation of wave power generation based on ship roll motion

Abstract

Oceangoing ships produce a roll motion under action of the waves. To absorb and use the energy of roll motion, it’s necessary to analyze the movement of the ship. That’s of great importance to discuss the feasibility of using the wave activated power generation and evaluate its energy conversion efficiency. In this paper, we choose the ITTC single parameter spectrum and adopt linear superposition method to establish the real-time wave model. Then we simulate the model and verify the correctness of the result according to the spectrum analysis. After that, the roll motion model and energy model of the ship are established. The simulation of the roll motion of ship support for the subsequent study of the energy absorption of the roll motion by basic data.
