Specialists from Composit and OOO MGB, have developed and introduced new dredging technology. Included in the Gefest dredger (from Damen), the Composit DU-630 sea slurry hose has a draft below water level, which means that the concentration of abrasive hydro-mixture transported (sediment, sand of varying capacities and other abrasive materials) is increased and subsequently raised back ascent to its original position.
