Abstract

In recent years, anchored vessels sometimes dragged their anchor and stranded incoastal zones during the evacuation at stormy weathers. It is very important to verify the accuracy of numerical simulation of anchored ship motions. In this study, some points of numerical simulations are improved to reproduce accurately the phenomenon of stranded casualties. The situation of the dragging anchor can be reproduced by solving the equation of motion at seabed. The approximated hydrodynamic forces of the anchor chain make the accuracy better. Finally, the detailedsituation can be reproduced by considering the dragging anchor, the drifting of ship and the hydrodynamic forces of mooring chain. It makes possible to simulateaccurately the safety of anchored vessels offshore harbour as the new planningscheme.
