The present study is numerical simulation result to solve two-phase flow around a two-dimensional (2D) barge platform in forced-rolling. A platform with a draft equal to one half of its height was hinged at the center of gravity and free to roll with waves that had the same period as the natural roll period of a barge platform. In order to simulate the 2D incompressible viscous two-phase flow in a wave tank with the barge platform, the present study used the volume of fluid (VOF) method based on the finite volume method with a standard turbulence model. In addition, the dynamic mesh technique was used to handle the motion of the barge platform induced by the fluid-structure interaction. Consequently, the present results are able to predict the relevant aspects of the flow field and roll motion of the barge platform structure.
