The present invention relates to an offshore floating wind turbine apparatus having a compression structure comprising floating support lines. More particularly, the offshore floating wind turbine apparatus includes a plurality of floating support lines (109) diagonally connected to the bottom of the sea at a deep depth of water and a plurality of inverted-triangular cables (127) connected to the floating support lines (109) with inward and downward tension. The upper portion of each of the inverted triangular cables has an expanded area for supporting a vertical type floating structure (106) on which the wind turbine is installed, and fixes the upper and lower ends of the vertical type floating structure (106), thereby maintaining a floating center. Also, the compression structure with floating support lines may be actively adjusted in height by mechanical devices within the vertical type floating structure (106) when the sea level changes, strong wind blows, or the wind turbine is being repaired. 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.
