Abstract
The development of Wave Energy Converters (WECs) is often carried out based on detailed analysis of a single unit. However, successful prototypes that will become commercial will be installed in wave farms where additional effects due to interactions between the WECs will occur. The current study presents results from time-domain coupled simulations, which are used to calculate, among others, the Levelised Cost of Energy (LCoE) and fatigue lives of moorings of the WEC system. Four types of wave farms were compared using the same point-absorbing WEC but with different mooring designs and array patterns. The fatigue damage of the moorings was found to increase for the arrays with strong hydrodynamic interactions and mechanical couplings. The results show that the LCoE value for a WEC array farm is sensitive to the hydrodynamic interaction between WECs and the mechanical couplings in the mooring design.
