Sažetak
One of the most important component in prediction of ship dynamic draught is squat. Ship squat is steady hull downward displacement due to relative water movement around ship hull. That phenomena causes different pressure distribution around the hull and causes water depressions in which ship sinks. Prediction of the ship squat can be made using proposed empirical formulas or navigational simulators. Empirical formulas are based on physical model testing and field measurements for certain fairway and ship configurations, while navigational simulators use complex mathematical and hydrodynamic modelling for given scenario to calculate and predict ship squat. The accuracy of the simulator models are tested on ship models and have proven accuracy in predicting ship squat. This paper analyses differences between modelled and calculated ship squat for two general types of vessels, in a narrow channel and for a different ships speed.
