Transient response of a moored vessel induced by a passing ship

Research output: Contribution to conferenceProceeding

Abstract

A passing ship sets up the wash waves, which are able to propagate a long distance with limited dissipation. The wash waves will induce transient loads on a moored vessel. In the present research, a hybrid model is developed to estimate the transient response of a moored vessel induced by another passing ship far away. The hybrid meth-od is based on the combination of the 3-D Rankine source method and the impulse response theory. The wash waves and the impact loads acting on the moored vessels are addressed using the 3-D Rankine source method. The transient response of the vessel is simulated with the impulse response theory. The transient response is found to increase with the passing ship’s speed. In addition, the propagation distance of the wash waves has a limited in-fluence on the transient response due to the dissipation feature of the divergent wash waves.
