This refers to a specialised form of service or yard craft constructed for the underwater excavation of soft sediment to maintain a specified channel depth for the passage of shipping. Various methods of excavation are employed, and some dredgers have integral hoppers to contain material being taken for dumping, while others require the associated use of a Hopper Barge.
