Abstract: Shallow water navigational safety is a major concern for vessels entering and leaving a harbour. This paper deals with the study of manoeuvrability deterioration of a container ship operating in shallow waters where this type of deterioration is a common phenomenon encountered by ships. In this paper the non-linear mathematical model proposed by Son and Nomoto (1981) has been considered. The manoeuvring coefficients have then been estimated using a RANSE based CFD method considering shallow water effects. The trajectories in shallow water have been compared with those in deep waters in order to quantify the deterioration due to shallow water effects.
