Computer based numerical prediction of wave-body interactions has become a powerful design tool and is widely used in the offshore industry. Its application to wave energy conversion is more recent. The present work investigates the modelling of three configurations of sloped wave energy converters of increasing complexity using the boundary element method package WAMIT. These configurations are all related to the concept of the Sloped IPS buoy wave energy device. In order to understand and assess the validity of numerical modelling for the specific cases considered, a two stage procedure is adopted. The first stage is to check that the results obtained from WAMIT are consistent with its underlying theory. These results are then compared with the corresponding experimental data. The experimental equipment and methodology are described. This includes discussion of wave tanks, models, and measuring techniques. The three configurations of wave energy converter investigated are the following: (a) a single degree of freedom system whose power take-off is referenced to the sea bed; (b) a free floating device with no power take-off; and (c) a free floating device fitted wit a power take-off mechanism that uses water inertia for its reference.
