The Motion Response of Trailing Suction Hopper Dredger under the Influence of Swell

Abstract With the continuous development of dredging business to overseas markets, ships are faced with a more and complex hydrodynamic environment. Swell long wave periods has great impact on adaptability ship operations. Focused Trailing Suction Hopper Dredger (TSHD), this paper studied motion response characteristics TSHD under influence swell. The result shows that is severely affected by amplitude increases increase height. When subjected transverse swell 90° direction, both heave roll most significant. While 0° only pitches violently. results can guide suitability assessment in area.
