When we consider manoeuvring performance of a ship which has a close relation to the hydrodynamic forces acting on a ship hull, we need to turn our attentions to not only deep water but also shallow water such as harbors and canals. Therefore, it is necessary to establish the prediction method which can take the effect of shallow water into account in order to estimate the hydrodynamic forces. In this paper, we investigated the hydrodynamic forces acting on a model ship which were a VLCC. We applied the slender body theory with the dispersive vortex model. Furthermore, we defined parameters "α" and "p" which represented the damping of vortex and effect of shallow water respectively, and examined the values of the parameters "α" and "p". From the comparison between the numerical calculations in the present method and the measured hydrodynamic forces, we examined the validity of the present prediction method of hydrodynamic forces acting on a ship such as, especially a tanker, in manoeuvring in shallow water.
