Ship motion responses and added resistance in waves have been predicted by a wide variety of computational tools. However, validation of the computational flow field still remains a challenge. In the previous study, the flow field around the Korea Research Institute for Ships and Ocean Engineering (KRISO) Very Large Crude-oil Carrier 2 tanker model with and without propeller condition and without rudder condition was measured by the authors, as well as the resistance and self-propulsion tests in waves. In this study, the KRISO container ship model appended with a rudder was used for the higher Froude number .26 and smaller block coefficient .65. The experiments were conducted in the Osaka University towing tank using a 3.2-m-long ship model for resistance and self-propulsion tests in waves. Viscous flow simulation was performed by using CFDShip-Iowa. The wave conditions proposed in Computational Fluid Dynamics (CFD) Workshop 2015 were considered, i.e., the wave-ship length ratio λ/L = .65, .85, 1.15, 1.37, 1.95, and calm water. The objective of this study was to validate CFD results by Experimental Fluid Dynamics (EFD) data for ship vertical motions, added resistance, and wake flow field. The detailed flow field for nominal wake and self-propulsion condition will be analyzed for λ/L = .65, 1.15, 1.37, and calm water. Furthermore, bilge vortex movement and boundary layer development on propeller plane, propeller thrust, and wake factor oscillation in waves will be studied.

When a ship sailing at low speed passes a moored ship with a drift angle due to wind effect, the flow field around the ships is very different to the flow field without a drift angle and will cause larger hydrodynamic forces on the moored ship, compared with those without a drift angle. In this paper, a flow model in XBeach is applied to study the effects of a passing ship at low speed with various drift angles on the moored ship. This method is based on the non-hydrostatic shallow water equations. Simulations are carried out for a 12500 TEU container ship passing a moored Panamax ship by using XBeach. The water level depression, return current and hydrodynamic forces on the moored ship are obtained and compared with the measurement data. Then the results at positive and negative drift angles are compared with the results at zero drift angle, respectively. The influence of the drift angle on the passing ship effects is analyzed and the most serious situation for the moored ship, when the passing ship has different drift angles, is indicated. Finally, conclusions concerning the effects of a passing ship with a drift angle on a moored ship are drawn.
