Abstract

Flexible piles (5) are arranged close to the center of the tower (1) and evenly spaced apart on a circumference the area of which is about 10% of the area of the tower. The product of the total buoyancy of the tower by the arm level between the buoyancy center and the center of the articulation is at least equal to 1.25 times the product of the weight of the platform by the arm level between the center of gravity and the center of the articulation.
