Tunnel dredge

A dredger is an important piece of equipment used in the construction of underwater tunnels. Dredgers are used to remove sediment and other materials from the seabed in order to make room for the tunnel to be constructed. There are various types of dredgers, including cutter suction dredgers, bucket dredgers, and trailing suction hopper dredgers, which are used depending on the specific requirements of the tunnel construction project. The dredged material can then be disposed of in a designated location, or used to create new land masses, such as islands or coastal defenses.
