Abstract

La présente invention concerne un procédé et un système qui transmet l'énergie houlomotrice absorbée par un ou plusieurs corps flottants, soumis au mouvement des vagues marines, jusqu'à un système convertisseur d'énergie installé en zone côtière. Le système est caractérisé en ce qu'il comprend une structure de type bras installée au-dessus du niveau de la mer, semblable aux grues à tour pour la construction de bâtiments. La structure de type bras contient et achemine un ou plusieurs éléments souples, chacun reliant et transmettant l'énergie depuis un corps flottant vers le système convertisseur d'énergie installé en zone côtière, à une hauteur au-dessus du niveau de la mer. Cela améliore le rendement énergétique, étant donné que l'élément souple est acheminé ou orienté, protégé et au-dessus du niveau de la mer, évitant ainsi les pertes d'énergie par étirement et par le phénomène caténaire, produit par son propre poids. Le système ne nécessite pas d'éléments immergés, offrant ainsi un faible impact environnemental, et une réduction des coûts d'installation et de maintenance, tout en considérant l'installation du système dans son ensemble dans la terre. La structure offre la possibilité d'approcher ou d'éloigner le corps flottant ou bouée à la zone côtière, avec pour objectif de protéger le corps flottant d'un orage, ou simplement pour effectuer de la maintenance.
