A preliminary study is made of the dynamics of Oscillating Water Columns (OWCs), in which the amplitude of internal fluid displacement is nonlinear. The OWC is a well-studied class of ocean wave-energy converters. When the machine's natural frequency is appropriately tuned, it will resonate at the prevailing ocean-swell frequency. Large amplitudes at resonance are desirable since they maximise the power available for electricity generation; however, large amplitudes also imply nonlinear behaviour. Most analyses of wave-energy converters of any class assume linear dynamics.
