Abstract

La présente invention concerne un appareil de type éolienne flottante offshore présentant une structure de compression comprenant des lignes de support flottantes. Plus particulièrement, l'appareil de type éolienne flottante offshore comprend une pluralité de lignes de support flottantes (109) raccordées en diagonale au fond de la mer à une profondeur importante et une pluralité de câbles présentant la forme de triangles inversés (127) raccordés aux lignes de support flottantes (109) présentant une tension vers l'intérieur et vers le bas. La partie supérieure de chacun des câbles présentant la forme de triangles inversés comprend une zone étendue permettant de supporter une structure flottante de type vertical (106) sur laquelle l'éolienne est installée, et assure la fixation des extrémités supérieure et inférieure de la structure flottante de type vertical (106), ce qui permet de maintenir un centre flottant. La structure de compression présentant les lignes de support flottantes peut également être ajustée en hauteur de manière active par des dispositifs mécaniques à l'intérieur de la structure flottante de type vertical (106) en cas de changement du niveau de la mer ou de vent fort, ou si l'éolienne est en cours de réparation.
