This paper presents a study on berthed ship passing ship interaction for two different channel widths using physical model scale physical experiments and Computational Fluid Dynamics (CFD). The interaction forces and moment and the sinkage of the berthed ship were measured for the two different channel widths. In order to determine the effect that the additional blockage caused by the berthed ship had on the squat of the passing ship, the squat was also measured under the same conditions as in the ship interaction scenarios, but without the presence of berthed ship. The two restricted water cases were replicated in model scale using 3D inviscid double body CFD simulations and validated against experimental results. The CFD models were run with the passing ship fixed in the static level trim condition as well as with the passing ship fixed at the running sinkage and trim condition measured from the physical model scale experiments to determine whether the latter would improve correlation with the experimental results.
