    • Backhoe dredger

      A backhoe dredger consists of a hydraulic crane with a heavy bucket that is mounted on a pontoon or a self-elevating platform. A backhoe dredger is mainly used to dredge hard materials like rock, boulders, underwater dams, removal of old revetments etc.

    • Barges

      Barges are ancillary equipment, used for the transport of soil. There are all kinds of possibilities to use barges. One of the most common is, that a dredging installation dredges the soil and disposes it in the barge. As soon as the barge is loaded, it sails with its own propulsion installation or with the help of a tug boat, to the dumping place. Barges discharge by means of bottom doors, they can also be split barges and there are also barges with no means of discharging at all. These will be unloaded with the help of for instance a barge unloading dredger.

    • Booster station

      The dredged material can be transported over long distances via pipelines. However, the pressure in pipelines gradually, due to friction and bends in the pipeline. This limits the distance over which the soil can be transported. A booster station can be added to the installation to extend the transport distance. A booster station is basically a combined engine and pump room, which can be installed in a pontoon or ashore to boost the pressure.

    • Bow coupling

      Part of a TSHD to which a floating discharge hose can be connected. As the name says the bow coupling installation is located at the bow of the dredger and is used to discharge the soil via shore pumping/pipelines.

    • Bow thrusters

      Bow thrusters are propulsion devices that are installed in the bow of a vessel to increase manoeuvrability. They are ideal for navigation in confined spaces, such as port basins or narrow channels, and they are also used to keep the dredger in place during rainbowing or discharge by pipeline.

    • Work boat

      Dredgers without any means of propulsion rely on work boats, push boats or tugs to position them in the dredging area. Work boats are also used for support operations, such as hoisting the cutterhead and pump parts, anchor handling, handling of floating pipelines and the transportation of people, fuel and goods. They are usually equipped with a hydraulic crane and anchor handling winches.
