Preliminary Investigation of a Novel Breakwater Combining Coastal Defence and Energy Generation for Near Shore Environments

This paper presents the concept and initial tank testing of a novel low profile floating breakwater incorporating energy generation. The breakwater is intended to be anchored parallel to the coast with a beach at the front of the device to rotate the incoming waves towards collector tubes. The water hammer principle is used to harvest the high water particle velocities, charging a rear mounted high pressure reservoir which is then used to drive a conventional turbine for electrical energy production. The ability to provide breakwater benefits in smaller wave climates should open areas where combined protection and generation give competitive economic returns.
