This paper describes the hydrodynamic forces acting on a ship hull undergoing lateral berthing maneuver. The hydrodynamic forces acting on the ship hull shows quite complicate and transitional characteristics due to the complex flow field around a ship and has a deep relation to the strength and position of vortices. In order to understand the phenomena for berthing problems, a numerical calculation for time-domain simulation using 3D CFD technique was employed for basic consideration of the hydrodynamic forces especially to estimate the drag force acting on a Wigley model moving laterally from rest in deep water. The numerical solutions successfully captured not only the characteristics of the transitional hydrodynamic forces but also some interesting features of the transient flow. The computational results of the hydrodynamic forces were in good agreement with experimental results.
