A Split Hopper Barge (SHB) is a vessel with a large open hold, used to load and transport dredged material. The Barge is loaded by a Cutter Suction Dredger or by a Backhoe Dredger. The barge is self-propelled, and sails to the deposit area, where it unloads the soil. The vessel consists of two halves, and unloading is done by opening, or `splitting`, the two halves, and depositing the soil on the seabed.
A hopper barge is a kind of non-mechanical ship or vessel that cannot move around by itself, unlike some other types of barges, that is designed to carry materials, like rocks, sand, soil and rubbish, for dumping into the ocean, a river or lake for land reclamation.Hopper barges are seen in two distinctive types; raked hopper or box hopper barges. The raked hopper barges move faster than the box hoppers; they are both designed for movement of dry bulky commodities.

There are several "hoppers" or compartments between the fore and aft bulkhead of the barge. On the bottom of the barge hull, there is (are) also a large "hopper door(s)", opening downwards. The doors are closed while the vessel is moving, so she can carry the materials that are to be dumped. The door(s) open when the ship has arrived at the spot where the materials are to be dumped.
