Therefore, there is a need to develop a river-sea direct ship type which is suitable for river and sea and can navigate the three gorges ship lock.

Among the existing three gorges ship type, the standard ship type with the plane dimension of 105m x 16.3m wide is popular, the ship type can navigate to various ports of Luzhou, yunnan, yangtze river trunk line and upstream main power ship type, and the ship type has the following combination type through the three gorges ship lock.

1. 105x 4 ship, ship lock 260-105 x 2=50 empty;

2. the ship length is 105 multiplied by 2+110 multiplied by 2, and the ship lock is 260- (105 multiplied by 2+110 multiplied by 2) =45m empty;

3. the ship length is 105 multiplied by 2+130 multiplied by 2, and the ship lock is 260- (105 multiplied by 2+130 multiplied by 2) =25m empty;

4. the 110×17.2m ship length is not matched with the ship model, and the width of 15.4m is wasted, and the ship model (32.6-17.2=15.4 m) is widely regarded by the shipping industry for the 110×17.2m ship model, and the ship model with the width of 16.2m is greatly exceeded in both ship performance and economy, so that the development of 105×17.3 ship model and 105×15.3 ship model matched with the ship model is necessary for the diving.
