ABSTRACT
The article describes simulations of ship motions on waves, taking into account whipping and springing phenomena, which have particular influence on the safety of container ships navigation. It indicates the selection methods of parameters of sea waves, which may cause the dangerous phenomena. The article presents the determination methods of the extent of the ship structure displacements during the ship motion on waves in result of free surface impact on ship’s bow flare region or flat surface of stern. Simplified method describing forced vibrations of ship structure apply the forces determined by simulations with the use of time-domain seakeeping code.
