Abstract

La présente invention concerne un corps flottant (200) permettant de porter une éolienne (100) d'un parc éolien de haute mer (300) flottant. Le corps flottant (200) comprend corps de stabilisation à disposer sous une surface de l'eau (50) et destiné à stabiliser la position dudit corps flottant (200) dans l'eau. Le corps de stabilisation comprend au moins un composant (410, 420, 430) d'un dispositif destiné au raccordement au réseau du parc éolien de haute mer (300). Ledit au moins un composant (410, 420, 430) est encapsulé de manière étanche à l'eau de mer.
