Cutter Suction Dredge Services

Cutter or Hydraulic dredges are floating platforms equipped with a rotating cutter that excavates the sea floor, feeding the loosened  material into a pipe and pump system that transports the material and water slurry up to typical distances of five miles. Transport distances can be extended by the addition of Booster pumps in the pipeline route.This method is most suited where the disposal location is within an economic direct pumping distance from the dredging location, typically no more than six miles. These dredges can pump a slurry of all types of material: mud, sand, clay and rock. The ability to dredge stiff or hard material is dependant on the size and weight of the dredging equipment and the installed power of the cutter, the ability to pump heavy material is dependant upon the installed power and size of the pumping systems.
