When entering waterways that are restricted either in height, width or by another vessel, the behaviour of a ship changes. The most evident effect of navigating in shallow water is the squat which has led to several groundings. Because of pressure differences the vessel is pulled down into the water and the trim is changed. Another shallow water effect is the speed loss due to an increase in resistance which can reduce the maximal speed by upto 50 percent. In general the behaviour of a ship in shallow water is said to be sluggish, meaning that it is more difficult to navigate which affects the radius of the turning circle among others. Sailing parallel to a close-by bank affects the lateral force and the yaw moment. The interaction with other ships has similar effects as bank effects, but is more sophisticated since more parameters play a major role. In this thesis each of these effects is researched by studying several papers by renowned researchers.
Several models are developed which are correspondent with the inherent model of forces and moments of the simulation program. The challenges and obstacles that arised during modelling and implementation are pointed out and solutions or approaches are given.
