Cutter Suction Dredger

    A cutter suction dredger is a type of dredging vessel equipped with a rotating cutter head at the suction inlet. The cutter head loosens the sediment on the seabed, which is then sucked up by the dredge pump and transported through a pipeline to a designated disposal site - pacific dredge .

   Our goal is to guarantee unparalleled satisfaction and success in every project we undertake. Dredging projects can be carried out nearly anywhere that has a body of water, from small ponds to major oceans. Both active and abandoned mine sites are potentially hazardous as waste products can leach or spill into the environment. Crisafulli dredges effectively remove, for proper disposal, these contaminated substrates, without damaging the geomembrane liner. Dredging also allows for the recycling of the tailings to produce additional minerals. The Crisafulli liner protection system enables operators to dredge lined lagoons without fear of damaging the geomembrane liner - tugboat service . These improvements make hydraulic dredging more reliable, cost-effective, and environmentally sustainable. A hydraulic dredge pump plays a critical role in sediment transportation by creating suction to lift and move slurry through pipelines. This pump generates the necessary pressure to tran...

  Hydraulic dredges offer a non-disruptive solution for desludging, enabling operations to continue uninterrupted without requiring a complete shutdown. Their enclosed pipeline systems prevent odors and reduce the potential for spillage or environmental contamination. Ports, harbors, rivers, and inland waterways require consistent dredging to maintain navigable depths. Hydraulic dredging is preferred for removing soft sediments, such as silt and sand, efficiently and with minimal disruption to marine traffic. Continuous operations with real-time monitoring enable the management of depth control while staying within environmental thresholds - mechanical dredging . For dredging, dredgers are used to remove the deposited sediments from an inlet creek, waterway or ocean floor. Sedimentation is natural, and sometimes excessive silt, sand, stones, and other debris accumulate on the bottom of canals, rivers, lakes, etc, reducing the waterways’ depths. Water depth influences the type and c...
