The effect of air chamber height, bow bottom plate length, mooring method and wave parameter on the distribution of operational range with high capture width ratio (CWR) were explored. Results revealed that the performance of a short air chamber is superior to that of a tall air chamber, and that the converter with bow bottom plates exhibit bimodal CWR distribution, while the converter with a floating ball mooring system exhibits trimodal CWR distribution and thus shows the widest working range among all tested cases. The influence of four representative actual waves on the mooring force of the wave energy converter with a floating ball mooring system was studied, and it was found that the maximum mooring force acting on the converter occurred under medium large wave conditions rather than the most extreme wave conditions.
