Last Sunday, September 8, the 16,500-cubic-meter hopper dredger Kaishuu began transporting silt from the Port of Hamburg to the North Sea, to buoy E3. Later than ever before. Why is that?
In recent years, sedimentation in the Port of Hamburg has been so severe that we usually had to begin maintaining water depths and transporting sediment to buoy E3 as early as possible—that is, as early as late June or early July.
However, since the turn of the year 2023/2024, discharge conditions have been significantly better than in the past 10 very dry years. In addition, we have consistently utilized opportunities for increased sediment removal to reduce small-scale sediment cycles—which lead to sediment buildup in the harbor. Together, these two effects have led to lower overall resedimentation that began much later in the course of 2024. We can therefore see that the removal is working, and with improved outflow, sedimentation in Hamburg is decreasing again.
