Jetting pumps supply water to the draghead to fluidize the sand being dredged. The trailing draghead connected to the end of the suction pipe travels over the seabed like a vacuum cleaner’s nozzle. It then discharges the hopper by bottom dumping or pumping through miles of pipeline in roughly the same time.ĭuring the dredging process, Magdalen lowers a suction pipe to the bottom of the seabed. As a result, the dredge can load up to 8,550 cubic yards of material in about an hour. The Magdalen, which is built on a Royal IHC design, uses three VACON® 3000 medium-voltage (MV) drives that supply electric power to a high-efficiency Royal IHC dredge and booster pump.
