Abstract

Marine cable-body systems deployed from surface support vessels are widely used in ocean mining. The present paper addresses their dynamic heave response under severe external excitation due to the heave motion of the surface support vessel. A single-degree-of-freedom model and a multi-degree-of-freedom model are presented. The former is to reveal the fundamental characteristics of the system under extreme excitation while the latter is for predicting the snap loading in the cable. The numerical examples illustrate that under such excitation the dynamic response of marine cable-body systems can lose its stability and become chaotic.
