Abstract

La présente invention concerne une bouée d'ancrage conçue pour l'ancrage de dispositifs d'exploitation d'énergies renouvelables marines qui permet sa fixation au dispositif et au fond suivant des géométries reconfigurables, y compris la rotation libre à l'horizontale du dispositif. Cette bouée permet l'orientation optimale du dispositif dans des zones à courants variables. La bouée comprend deux parties principales: une partie extérieure à laquelle sont raccordés les câbles résistants et électro-optiques qui relient la bouée au dispositif et un noyau intérieur qui est relié au système d'ancrage et duquel sort le câble d'exportation d'énergie, la rotation d'une partie par rapport à une autre étant ainsi possible. L'ensemble comporte une série d'ouvertures de liaison dans la partie inférieure et une cloche à air intérieur qui permet l'utilisation d'équipements intérieurs classiques.
