Dynamics of Heaving Buoy Wave Energy Converters with a Stiffness Reactive Controller
Heaving buoy wave energy converters (WEC) are floating oscillators, commonly modeled as single-degree-of-freedom vibrating systems. As the wave frequencies change according to the sea state, these devices must be controlled to maximize energy absorption.

Investigation of Vertical Slamming on Point Absorbers [PDF]
This paper focuses on the impact of vertical slamming on floating point absorber systems and the associated pressures that might be expected when these phenomena occur. In a first part it will be shown how the occurrence probability of slamming can be reduced by implementing a slamming restriction, i.e.

A Flexible Chain Proposal for Winch-Based Point Absorbers
Ocean wave power is a promising renewable energy source. It has, however, been difficult to find a cost-effective solution to convert wave energy into electricity. The harsh marine environment and the fact that wave power is delivered with large forces at low speed make design of durable mechanical structures and efficient energy conversion challenging.

Design and Optimization of a Point Absorber for the Mediterranean Sea
Abstract In the last few years, a wide range of Wave Energy Converter (WEC) have been designed. Among the most interesting technologies for multiple applications, there is the point absorber: if on one hand, these devices guarantee a limited energy production, on the other hand, they ensure good performances, do not require complex ...

Cost-Based Design and Selection of Point Absorber Devices for the Mediterranean Sea
Sea wave energy is one of the most promising renewable sources, even if relevant technology is not mature enough for the global energy market and is not yet competitive if compared with solar, wind and tidal current devices.
