Top 10 Dredgers in the World

Here is the list of Top 10 Dredgers in the World, Large dredges that are used to cut and extract material from the seabed and raise it to the surface, allowing for the construction of various types of coastal structures. These are the top ten most incredible Dredgers on the planet.

What are Dredging and dredgers?

Dredging is the process of shifting dirt underwater. It can be used for a variety of applications. By removing mud, sludge, gravel, and boulders, one of the applications addresses the need to maintain minimum depths in canals and harbors.

Environmental dredging and clean-up of contaminated sediments; replenishment of beaches and coastlines, not only for coastal protection, but also for recreational uses; creating new land for port and industrial development; trenching, backfilling, and protection work for offshore pipelines, coastal outfall pipelines, and cables laid on the sea bed; environmental dredging and clean-up of contaminated sediments, Dredging can be done in two ways: mechanical excavating and hydraulic excavating. On cohesive soils, mechanical excavation is used. Mechanical grabs, buckets, cutter heads, and scoops are used to excavate and remove the dredged material.

In cohesionless soils like silt, sand, and gravel, hydraulic digging is done with specific water jets. Using centrifugal pumps, the dredged material that has been freed from the seabed is sucked up and transported as a mixture (solid material and water).

Types of Dredgers

  • Mechanical dredgers
  • Backhoe dredger
  • Bucket chain dredger
  • Cutter suction dredger 
  • Grab dredger
  • Suction dredgers
  • Plain suction dredger
  • Trailing suction hopper dredger ( TSHD )
