Abstract

The dynamics of an offshore mooring tower are complex due to the large non-linearities inherent in a system of this type. The paper presents comparisons of measured motions with theoretical predictions of motion for some simplified single-degree-of-freedom models for such a system. Numerical predictions of motion for the full two-degree-of-freedom system are presented, and reveal large amplitude motions, multiple solutions, sub-harmonic motions and even the potential for chaotic vibrations of the tower.
