In this paper, the nonlinear dynamics of a multi-module floating airport is studied. The floating airport consists of a number of floating modules serially coupled by flexible connectors. A non-autonomous network model is proposed with a new feature of piecewise nonlinear coupling. The investigation focuses on the onset of the phenomenon of amplitude death that corresponds to the oscillation suppression of the floating structure in waves. Parametric domains of the coupling strengths are analyzed for the amplitude death, and the underlying mechanism is further discussed. The transitions among different dynamic patterns are illustrated. Various types of collective behaviors in the network can be observed, such as complete synchronization, generalized lag synchronization, and phase-locking phenomenon. The amplitude death behavior is considerably valuable in providing theoretical guidelines for the safety design of very large floating structures.
