Numerical Modeling Study of Drifting Trajectory of Falling Containers in Xiamen Sea Area
With the continuous development of maritime economy,China's container transport demand is growing steadily.Under the changeable marine transportation environment,the potential danger to sea navigation brought by containes falling off ships gradually emerges.Based on the analysis of the immersed process of the falling container,the linear relationship between the coefficient of the wind drift and the immersed ratio of the falling container is proposed.Taking the containes containership＂SITC PYEONGTAEK＂ in the Xiamen sea area as an example,a container tracking model was established based on the particle tracking method combined with Lagrange and Monte Carlo random diffusion to simulate the trajectory of the containes.A grid-discrete statistical scheme was used to analyze the drift positios of the falling container.The model was verified by using the drift track of containers after falling into water in practical cases,which showed that the track points simulated by the model were basically consistent with the floating container points found at sea after the accident.The model has certain application value,which is conducive to quickly locking the drift area and reducing the risk caused by fall-ing containers.This helps to increase the accuracy of shipping companies prediction on the drift track of containers falling into water,and to ensure navigation safety in the port area with falling containers and its adjacent waters.
