Maintenance dredging
Sedimentation reduces the depth of port basins, jetty berths and shipping channels until vessels can no longer berth or pass safely. We restore that depth by grab dredging: a crane barge is positioned at the work area, its grab removes material from the seabed, and the material is loaded directly into a hopper barge moored alongside.
Our crane barges have 26–35 m booms and grab options from 4.5 to 12 m³, including heavy-duty and orange-peel grabs for heavier material.
