The cutter suction dredger is a vessel that dredges while it is moored with the help of spud posts and/or anchors. The dredging involves forcefully cutting into the soil with a cutter head and sucking up the loosened material. The dredged material is disposed of or used in land reclamation projects. It is transported by dry bulk cargo barges or - more commonly - pumped on land via pipelines.

For the construction of Maasvlakte 2, the cutter suction dredgers will be dredging the port basins to a depth of -20 m. In the process, they will transfer some 30 million m³ of soil from the existing port to the port sites under development.

The average length of a cutter suction dredger is 90 m.
