Review on Mooring Lines Damping for Wave Energy Converter (WEC)
Abstract
The WEC mooring system is needed to withstand the environmental loadings and to limit the excursion of the floating structure without affecting the power production efficiency. MDD type WEC is designed to have device resonant period match to mooring system at the wave frequency (WF). A coupled time domain analysis has to be used to analyze the influence of mooring line to the WEC motions. A literature review on the methods used to estimate the mooring line damping for WEC has been conducted. It is found that finite element method is can be used to model the nonlinearities of mooring line better than quasi-static method.
