Abstract

A recent challenge within offshore technology is the development of compliant systems for marine operations. Such a system may be composed of a floating part, being exposed to the wind and wave environment at the sea-surface, and by moorings or tendons for positioning. The system may experience slowly varying oscillations in the horizontal plane at the relatively low natural frequencies of the horizontal modes of motion. These oscillations are determined by the nonlinear wave and wind excitation loads, the natural frequencies of the different modes of motion, and by the damping forces.
