Multi-chamber OWC devices to reduce and convert wave energy in harbour entrance and inner channels

Physical model tests on a new Italian concept of wave energy converter named SeaBreath were carried out in the 36 m × 1.0 m × 1.4 m wave flume of Padova University. Beside energy harvesting, the device has a secondary purpose, i.e. it plays the role of a small floating breakwater. An example application is proposed for the deep "Petroli Channel" in the Venice Lagoon, that is plagued by continuous bank and marsh erosion induced by excessive waves generated by boats and ships.
