It is required to study the seakeeping performance to ensure a ship's safety and efficiency. The ship is not only operated on deep water journeys but also in shallow water during operation. In the deep sea, the characteristics of ships are mainly caused by random waves. However, the interaction between the ship and the bottom of the water usually occurs when the ship is moving in a shallow water area, and it can lead to change in the draft and motion of the ship as well as increasingly dangerous. This paper compares the motion characteristics of a container ship in harmonic waves in shallow waters with the ratios between the water depth and the ship's draft equal to h/T=1.2; 1.5; 2.0, and . The ship responses varying with wave frequency are analyzed to evaluate the influence of shallow water on the ship's motion characteristics based on numerical simulation methods.
