Abstract

The motion performance of damaged hybrid monohull is researched including influence of floating condition variety and liquid tank sloshing. Added mass of sloshing is solved by panel method considering resonance phenomenon and influence of fluid viscous damping on sloshing load. The formula of mass force and hydrostatic restoring force are derived under non-upright floating condition and 3D potential flow theory is used to solve the liquid load of hull motion and sloshing. The damaged ship motion equation is established based on the above method. Some questions are analyzed after the prediction like motion and wave load response before and after damage, effects of floating condition and stability and sloshing on motion response after damage. These researches indicate that after damaged the floating condition, stability, and liquid tank sloshing would influence the motion and wave loads of hybrid monohull.
