The structure of the Floating Dock is very special. It has a huge concave-shaped cabin with walls on both sides and an open front and rear end. It is a trough-shaped punt with a special structure. The wall and bottom of the wall on both sides of the dock are box-shaped structures, which are divided into a number of closed compartments along with the vertical and horizontal directions. Some of the compartments are called water tanks, which are used for watering and draining to make the dock sink and float.

In addition to ensuring buoyancy, the bottom tank can also support the ship. The function of the dock wall is to ensure that the dock has the necessary rigidity and floating stability and to provide the space required for the production.
