WERKWIJZE EN INRICHTING VOOR HET OVERBOORD AFVOEREN VAN HET OVERTOLLIGE WATER IN HET LAADRUIM VAN EEN HOPPER- ZUIGER OF DERGELIJK BAGGERVAARTUIG.

摘要

The method for discharging muddy water from a hopper dredger comprises overflowing excess water from the hopper to an independent trough, flowing the excess water in the trough through an irregular path and maintaining the excess water in the trough for a time period sufficient that air bubbles are removed, and discharging over board the excess water from the trough to an area below the water line of the dredger. Compressed air is blown into the excess water as it flows through the overflow trough, for eliminating fine air bubbles in the excess water.
