    project 3287

    Type: suction non self-propelled dredger with diesel and sectional folding case.
    Designation: development of sand and gravel soils of I-IV and I-III category respectively, transporting it as a water-mixture (slurry) to a place of installation or recycling.
    Owner: JSC "NSC Arkhangelsk".
    Flag: Russia.

    The dredger has an engine bilge type room in which are located a soil pump, a diesel engine and accessories. An auxiliary electric unit is located on the deck.
    There is a crane on board with an electric hoist (lifting capacity - 1 t) for the maintenance and repair of the soil pump.

    The dredger has a control cabin (wheelhouse), a latrine and a household pantry.
    A wheelhouse and an engine room are provided with ventilation and heating. The dredger has a wheelhouse measuring system with an industrial computer to supervise a dredging process, issuing information of the key operational parameters.

    The dredger is equipped with a plastic slurry-pipeline DN 300 with ball joints.
    Additionally, the kit supplied with the dredger:

    • a crane (lifting capacity - 2 t) for laying anchors and maintenance dredging and floating slurry-pipeline;
    • a floating pumping station for water recycling;
    • a residential unit for team members to stay on the shore;
    • an exchangeable soil intake device with: cutterhead, hydroripper, ejector suction head or hydromechanical bucket ripper.

    The dredger can be relocated in a disassembled form (road, sea, rail). The dredger set with 24 intermediate sections of a floating slurry-pipeline (150 m) can be shipped in 18 wagons.
