    Abstract

    A ship moored in a port is subjected to both the sea waves and the wash waves produced by nearby passing ships. A hybrid numerical model is proposed to estimate the transient response of a moored ship exposed to the two types of waves. The hybrid method is based on the combination of 3-D Rankine source method and impulse response theory. The 3-D Rankine source method is applied to address the wash waves and the wave-structure interactions. The transient response is subsequently simulated in time-domain with the impulse response theory. The transient effect produced by the wash wave impact loads is found to be dependent on the sea waves induced response. The transient effect becomes less significant when the sea waves induced response is strong and vice versa. Besides, the propagation distance of wash waves has a limited influence on the transient response due to the dissipation feature of the divergent wash waves. The transient response in stochastic sea waves is also investigated, which is dominated by the resonant frequency, the sea wave frequency and the wash wave varying frequency.
