Floating wave energy point absorbers-tuning facilities to enable wide band response from incident waves

摘要

A control system for a wave energy device (10) is provided. The system comprises means (20, 21) for adjusting the natural frequency of oscillation of a device in use. The system can be used to tune the oscillation of a device to optimise energy abstraction or de-tuned to stabilise a device during high seas or during maintenance.
