The onset of chaotic motions of a moored semi-submersible.


Journal Article

This paper describes a combined numerical and geometric approach to study the dynamic behaviour of a moored semi-submersible based on solutions of the non-linear differential equation used to model the system. Complex features including competing steady states, subharmonic resonances and chaos are shown to be typical responses in regular seas. A qualitative overview was used to classify the computer data generated from direct time simulation with the aim of illustrating the inadequacies and limitations of a linear or a purely analytical approach.
