Abstract
Object and purpose of research. The investigation considers approaches for inclusion of sloshing and ship speed and discusses their influence on estimation of hull responses to external loads. Materials and methods. The 3D panel method is used to solve a hydrodynamic problem of potential flow around ship hull in regular waves. The sloshing is included by direct modeling of inner tanks also containing potential fluid. The ship speed is taken into account by additional potential of inflow. Main results. Analysis of response amplitude operators (RAO) and bending moments with and without additional factors introduced in the mechanical model. Conclusion. The problem of ship motions in regular waves taking into account sloshing and ship speed was solved in the work process. The influence on responses of the considered mechanical system for taking these factors into considerations is analysed. The applied panel method shows flexibility regarding additional factors of modeling and offers a prospect for further investigation of non-linear effects associated with ship motions in waves.
