Abstract

The analytical 3D model of Renzi and Dias (2012) developed to investigate the resonant behaviour of an Oscillating Wave Surge Converter (OWSC) in a channel is used here to study the hydrodynamic loading on an array of devices in random seas. Within the framework of a linear theory, separation of variables and the application of Green's theorem yields a hypersingular integral equation for the velocity potential in the fluid domain. The latter is solved with a series expansion in terms of the Chebyshev polynomials of the second kind. The physical behaviour of the system is investigated demonstrating the effects of five different random sea states on the hydrodynamic loading on the converters. The most effective of the five sea states examined is shown to be a realistic case for a nearshore OWSC configuration off the west coast of Ireland.
