General info on Dredging.
A hopper barge worked in conjunction with dredgers. The dredger would remove spoil from the sea bed and dump it via chutes into the hold of the hopper. When full the hopper would proceed to sea where it would dump its load. In the bottom of the hopper barge where a series of doors built into the bottom hull,which were opened to allow the mud to fall out. This mud was obviously replaced by sea water which flooded in. This was not pumped out, the doors being closed and the hopper proceeding back to the dredger. When the next load of spoil, was placed in the hopper the sea water simply overflowed onto the deck and back into the sea.
