Why choose our Cutter Suction Dredgers?

Main benefits

  • High efficiency & production capacity

    The dredge pump is submersible. Due to this, the pump has a higher pumping flow and can handle a mixture of higher density. Additionally, an underwater dredge pump will not reach the vacuum limit, especially when dredging at the depth of 6 metres or more. Therefore, this pump results in more production than a dredge pump mounted in the pontoons.

  • Low Consumption

    The pump speed is adjustable, which allows it to have the right pressure in accordance with the suction depth and discharge pipeline. As a result of this, the system becomes more efficient, because it consumes less fuel per cubic meter of production. Furthermore, the dredge pump and pipes will wear out less.

  • EASY MOBILIZATION IN THE WATER

    The cutter suction dredger can be supplied with high-efficiency hydraulic thrusters. Dredge propulsion allows the dredger to move around the dredging area without any involvement of supporting boats.

  • Easy sailing & storage

    The dredger has two tilting spud systems, which can be manually tilted and secured to the deck. This design ensures easy dredge mobilization, transport in the water and road on a flat-bed truck, as well as practical storage.

  • One-man operation

    The entire dredger and all its equipment can be controlled from the control cabin. Therefore, Dredge Yard dredgers can be operated by a single individual, without any support.

  • Transport

    An entire dredger can be transported in assembled or disassembled states. More specifically, a disassembled dredger can be transported in 4 standard containers. Furthermore, our dredgers can be assembled without the need of special tools. However, if required, Dredge Yard can send service engineers to your site to support with assembly and commissioning. Finally, an assembled dredger can be transported on roads using a flatbed trailer and can be launched into the water using one single crane.

  • REPLACEABLE CUTTER TEETH

    Cutter suction dredgers provide the possibility to replace cutter teeth to improve cutting performances. Cutter head teeth replacement can be done for two purposes. More specifically, to replace worn out original teeth, or to match the teeth to the particular type of soil, silt, sand and minerals. For this purpose, there are three different types of teeth, namely sharp point, medium edge and wide edge. Finally, the teeth are fixed with a bolt and nut connection. Therefore, they can be replaced fast and easily.

  • CABIN WITH ALL NECESSITIES FOR SAFETY AND COMFORT

    Cutter suction dredger cabin is provided with all necessities for the operator’s comfort and safety. For example, the cabin is supplied with noise reduction, ventilation, windshield wipers, an adjustable chair and a lock door, to name a few. In addition to this, air conditioning or a heater is included depending on the geographical location of operation. Finally, the cabin is mounted on vibration isolation pads or a vibration reduction mount in order to minimize the vibration and increase comfort.

  • RELIABLE BRANDS

    All Dredge Yard equipment originates from reputable manufacturers with proven designs. Likewise, cutter suction dredger is constructed of highest quality components from well known, first class brands. Furthermore, manufactured parts such as the hull and steel components of the cutter suction dredger are designed and inspected by the Dredge Yard team of experts.

  • SHALLOW DRAFT

    The cutter suction dredger is designed with three main pontoons – one in the center and one on each side. The pontoons provide sufficient floating capacity achieving draft of less than 0.8m (2.65ft). Accordingly, allowing the dredger to operate in shallow waters.

  • VERSATILITY

    Dredge Yard dredgers can be modified between cutter suction dredgers, auger dredgers, plain suction dredgers and swing suction dredgers. The modification parts can be installed at location during initial dredge purchase or later as needed. Therefore, our dredgers are very versatile and can be used for dredging all types of soils including sand, gravel, silt and more.

Dredge system

The cutter suction dredger is equipped with a stiffened ladder in order to adapt the dredger to operation at different depths. More specifically, the cutter ladder is lifted by a hydraulic winch, which is mounted on the pontoon in front of the cabin. Finally, two hydraulic winches are mounted on the center pontoon for the swing of the dredger. These hydraulic swing winches are connected to the anchors via a heavy-duty tumbler in front of the cutter ladder.

Power

Our cutter suction dredgers are supplied with a reliable and efficient, diesel-driven, hydraulic power unit. In addition to this, an air radiator is installed to cool the diesel engine and the hydraulic system.
