Abstract

In the present paper, two types of wave energy converters (WECs) in uni-/multi-directional waves are investigated using a potential-flow model. The first example is a flap-type oscillating wave surge converter (OWSC) which is similar to the configurations of Oyster wave power device. The second case is an attenuator-type WEC which is based on the Pelamis P2 machine; the modelled WEC is simplified as 5 interconnected rigid modules. Both hydrodynamic interactions and mechanical connections have been considered in the present analyses. The emphases have been put on the effects of directional spreading on the performance of the WECs. Significant reductions of power output have been found in multi-directional seas.
