The floating structure (20) for supporting a marine wind turbine comprises a tower (21), a float (23), and a transition element (22) between the tower (21) and the float (23). The tower (21) has a tower tubular wall (31) having a tower axisymmetric outer surface about a central axis (5) defined by a tower generatrix, the float (23) has a float tubular wall (33) and a float lower end closing wall (34), the float tubular wall (33) has a float axisymmetric outer surface about the central axis (5) defined by a float generatrix, and the transition tubular wall (32) has a transition axisymmetric outer surface about the central axis (5) defined by a curved concave transition generatrix which is tangent to the tower generatrix. The transition axisymmetric outer surface of the transition element (22) has a transition upper diameter equal than a tower lower diameter (D1) and a transition lower diameter equal than a float upper diameter (D2). At least the float tubular wall (33), the float lower end closing wall (34) and the transition tubular wall (32) are made of reinforced concrete forming together a reinforced concrete monolithic body.
