CSD-Deep Suction Dredger
The CSD-D: Cutter Suction Dredger Deep cutting is built for greater depths.
When the cutting depth exceeds 22 meters it becomes increasingly difficult to counterbalance the occurring forces with a containerized pontoon. We created a solution for this situation whereby the cutter ladder runs around the outside of the dredger. This wide ladder construction causes the torsion forces to be counteracted at the bottom end where the cutter unit is situated. By placing the pontoons further apart cutting up to a depth of as deep as 80 meters becomes a possibility.
The CSD-D is equipped with an Xmas tree instead of spud poles. This system has the advantage of it being easier to reposition the dredger and enabling working at greater depths.
This dredger can be equipped with a special connectable suction tube, whereby profile dredging is also an option.
