Grab or Clamshell Dredgers

Grab or clamshells dredgers are very commonly used, rather simple and easy to understand stationary vessels, with and without propulsion.

Fall Pipe Vessels

Fall pipe vessels operate in deep water covering offshore oil and gas pipelines, levelling the seabed or applying scour protection.

Environmental Equipment

Environmental dredging equipment is specially designed or adapted to remediate waterways that contain contaminated sediments.

Dustpan Dredgers

Dustpan dredgers are plain hydraulic suction dredgers that function like giant vacuum cleaners and are primarily used on river systems.

Dipper Dredgers

The dipper dredger is a powered bucket mounted on a barge which scoops material with a forward motion like a shovel toward the dredger.

Cutter Suction Dredgers

A cutter suction dredger is a hydraulic dredger that uses centrifugal pumps with a rotating cutter head to loosen, lift and transport dredged material.

Bucket-Wheel Dredgers

A bucket-wheel dredger has a rotating mechanical device, an excavator, perpendicular to the ship’s axis, mounted in front of the suction head.

Bucket-Ladder Dredgers

A bucket ladder dredger has a series of buckets mounted on an endless loop that scoop material from the waterbed and deposit it through a chute to a barge.
