Analysis of Moored Ship Motion under Impulsive Forces

Abstract:

To prevent the damages of the moored ship and the wharf structures in heavy weather, the ship motion and its effects on the wharf are analyzed. The moored ship motion in high winds with big waves was investigated. Firstly, the lateral wind loads and wave loads were considered as periodic impulsive forces, and the simplified dynamical model was presented. Based on the presented nonlinear impulsive differential system model, the numerical simulations and analysis were performed. The effects of recovery coefficient, damping and stiffness parameters on the system behaviors were discussed. Finally, some suggestions were made to guarantee the ship's stability or practical stability in heavy weather, and the safety of the wharf structures is thus assured.
