Abstract:
Floating system for a very deep water comprising at least one floating structure subjected to external loadings inducing stresses within the said floating system, the said floating structure being held in position on the sea bed by means of one or several tensioned lines made of a material with given mechanical properties characterized in that: the said tensioned line or lines are made of a material not very sensitive to fatigue, the said tensioned line or lines are sized independently of the fatigue phenomena associated with the dynamic behavior of the said floating system under the effect of external loadings, and the said floating system possesses several natural periods Tj, of heave T1, of roll T2 or of pitch T3, and in that at least one of these three values (T1, T2, T3) is within the range of periods Te of the wave excitation.
