What Are Different Types of Dredging Equipment?

What Are the Different Types of Dredging Equipment? Below, we will briefly discuss the differences between four types of dredges: Cutter suction dredgers, Remote control dredgers, and Dustpan dredgers. Depending on the kind of job, each has its advantages and disadvantages. Learn more about these machines to determine which one best suits your needs. You can also learn more about it at dredging equipment spring tx.

Dustpan dredges
Although dustpan dredges are commonly used to clean river channels, their capabilities are limited, especially in open waters. This equipment also tends to be sensitive to large waves, which makes them impractical for use in inland waters. Conventional models do not have self-propulsion and require large towboats to move them from place to place. They were first developed to maintain navigability along the Mississippi River during low river stages, where the soils of the Missouri River are most common. Today, they are used to support the open reaches of the Mississippi, Missouri, and Ohio Rivers.

Dustpan dredgers are unique to the Mississippi River. They employ a large suction mouth and a multitude of high-pressure water jets to agitate and break up the material to be dredged. Then, high-pressure water jets are directed into the material to be dredged by the dredge pump, and the slurry is deposited outside the navigation channel.

Cutter suction dredgers
Cutter suction dredgers work as cutters for a pipeline. The cutters can also load barges or act as loosening devices for other dredgers. The most common use of this type of dredging equipment is pipeline offloading. However, this dredging equipment is susceptible to waves and may obstruct other vessels. Additionally, part of the pipeline may be submerged and laid on the sea bed.

When comparing cutter suction dredgers with other dredging equipment, it is essential to understand their fundamental differences. While cutter suction dredgers are mainly used for capital dredging, they are also helpful for reclamation dredging. In addition, smaller models are designed to be transportable by road or rail, while larger ones are used for larger projects and are self-propelled.

Water injection dredgers
Different dredging methods
 require different types of dredging equipment. For example, water injection dredgers use a chamber with inlets to enact a dredging operation. Typically, these dredgers are suspended from a crane on land or a small barge. Seabed dredgers use a suitable vessel to pull them over the seabed. They have an effect similar to that of a bulldozer on land.

A water injection dredger is self-propelled and uses natural forces to transport sediments. Because the sediment is denser than water, it will be carried away by currents and gravity. These dredges are not only eco-friendly but also cost-efficient compared to traditional dredging methods. They also use significantly less energy and produce lower CO2 emissions per m3 than conventional dredges.

Another type of dredging equipment is a vacuum dredger. It uses the same principle as its namesake, using high vacuum pressure. Again, a crane holds the chamber and pumps in the sediment. After the work is done, the vacuum dredger is raised and emptied at the dredging site. These dredgers are used in ports around the world.

Remote control dredgers
With the Dragflow remote control dredger, dredging can be performed with the push of a button, even if you are not at the site. The dredger features hydraulics with four cylinders for dredging depth and angle. The dredger has an optional GPS tracking system and can work at a depth of 20 meters. It can be operated by remote control from a bus.


The remote-control dredgers are controlled through a communication system, which transmits the dredging ship's position to an onboard computer. The control is received by the ship's computer and translated into a movement based on a map stored in its memory. The ship's hydraulic pressure is then transmitted to the shore. Moreover, the draught and loading monitors allow the operator to determine the
amount of dredged material continuously.
