Le dispositif objet de l'invention a la particularité de capter directement, à travers un flotteur libre, la variation du niveau de mer verticale due à la houle, c'est à dire, il exploite directement les mouvements de translation. En dotant les digues verticales de protection maritimes ou portuaires de ce dispositif, on profite des avantages de l'on-shore (accessibilité, raccordement, abris, à faible investissement et coût de maintenance) tout en étant offshore (houle non amortie - pleine énergie aux alentours des digues de protection verticales). En maîtrisant les interactions avec les éléments de fixation, grâce à un système de canalisation à triple rails installés sur paroi de la digue, le dispositif permet d'élargir le champ d'exploitation de l'énergie de houle en allant vers des amplitudes de houle plus importantes.The device which is the subject of the invention has the particularity of capturing directly, through a free float, the variation of the vertical sea level due to the swell, that is to say, it directly exploits the translational movements. By equipping vertical sea or port protection dikes with this device, we benefit from the advantages of on-shore (accessibility, connection, shelters, low investment and maintenance cost) while being offshore (non-damped swell - full energy around vertical protective dikes). By controlling the interactions with the fixing elements, thanks to a system of triple rails installed on the wall of the dike, the device makes it possible to widen the field of exploitation of the energy of swell by going towards amplitudes of swell more important.

Le dispositif est doté d'un système d'amplification en permettant de canaliser les houles incidentes et d'amplifier l'énergie incidente au dispositif ce qui va optimiser son rendement et élargir les périodes de fonctionnement. The device is equipped with an amplification system making it possible to channel incident swells and amplify the energy incident to the device, which will optimize its efficiency and extend the operating periods.
