This paper describes a small segmented oscillating water column (OWC) with three sections and the modelling techniques that can be used to simulate its performance. The turbine uses cascaded Savonius rotors and the unit is developed and tested for validation of the performance algorithms. It is shown that the systems can be easily described and developed. It would be suitable for a shoreline location such as a harbor wall, where waves are random and not orthogonal to the column. Conversion rates in the region of 20% are tabulated for the system with an output of 25-W peak. A full algorithm used for the system is put forward and solved using the RungeKuttaNystrom (RKN) method.
