A non-linear potential model to predict large-ampli tudes-motions: application to a multi-body wave energy converter.

The paper is dedicated to the study of non-linear w aves acting on three dimensional surface-piercing structures. A time-domain non-linear potential-flow model has been developed to predict the largeamplitude motions of devices in a prescribed seaway. While earlier models have been developed for sing le wave energy devices, this paper addresses multi-bod y devices, with particular application to the WAVEBOB wave energy device.
