The cutter suction dredgers of Tianjin Waterway Bureau are slightly stronger, and most of their names begin with the word "Tian". The largest cutter suction dredgers are Tianqi and Tianlin, with a nominal production capacity of 4200m? /h, these two sister ships are the largest cutter suction dredgers in China at present.
Shanghai Waterway Bureau's harrow suction ships are a little stronger, and most of their names begin with "Xinhai". The cabin capacity represented by Xinhaifeng is about 16000m? Our ship should be the largest and most advanced trailing suction dredger in China. It is said that the biggest one is the new sea lion. Although it is big, it is really inefficient and difficult to get in.
Guangzhou Waterway Bureau has the largest grab ship in China, with a maximum bucket capacity of 50 cubic meters, but its efficiency is not as good as that of the new sea clam ship with a bucket capacity of 27 cubic meters of Shanghai Waterway Bureau.
I have seen most of the above boats, and there is another dredger called chain bucket dredger, which has been basically eliminated.
If you only answer the name of the largest dredger in China, you can only say that it is Xinhaifeng.
