New to cutter dredgers? Read our explainer on how a cutter dredger works.
A cutter dredger, also known as a cutter suction dredger, uses a rotating cutter head to break up compacted soil before pumping it away as slurry. Bell’s cutter dredgers are multifunctional dredges with suction and cutting depth up to 9 or up to 15 meters. It’s available in two variations: diesel driven or fully electric. The BCD is multifunctional because different types of dredge heads can be installed for all different types of soil.
The water jet assisted cutter head is for compact layers of sand and clay. The water jet assisted double cutter head with double cutter power is for even harder materials. And the water jet assisted sand production head is for loose materials like silt, sand and gravel.
We can modify the design to every customer’s needs.

The cutter head on the ladder rotates and loosens the soil. The dredge pump behind it sucks the loosened material up as slurry and sends it through the discharge line to the disposal site. The dredger is positioned with two spud poles and two mooring winches. The models differ in pump size, from the Bell 250 to the Bell 400, and in how deep they can dredge. Read the full explanation of how a cutter dredger works.
The Bell cutter suction dredger is built using 2 floating bodies in a catamaran position and an installation room in the middle. This gives the most stability on water for the best performance. From the wheel house you can control the cutter dredger and it gives you a clear view on the cutter dredger and around it. Performance, reliability and comfort are key words in this design.

A cutter suction dredger has a rotating cutter head that breaks up compacted soil, and a dredge pump that moves the loosened material away as slurry. The Bell version is built as a catamaran, with two floating bodies and an installation room in the middle.
The Cutter Dredger 250M has a suction and cutting depth of up to 9 or up to 15 metres. The 300-350 and 400 models cut up to 15 metres and dredge up to 21 metres.
Both. Bell cutter dredgers can be diesel driven or fully electric. The electric version suits areas with emission restrictions.
The head decides. The water jet assisted cutter head is for compact layers of sand and clay, the double cutter head for harder material, and the sand production head for loose material such as silt, sand and gravel.
Yes. Bell cutter dredgers are available for sale and for rental.
The modular construction allows containerized transport and fast assembly on site, which helps on remote or logistically difficult projects.
