Storage for Elbe dredged sediment completed
Close to the port of Cuxhaven in Germany two underwater deposit areas were successfully completed by Jan de Nul and Van den Herik, commissioned by the Germany’s Federal Waterways and Shipping Administration (WSV). The main goal was to store sediment dredged from the Elbe River as part of a deepening project and avoid the sediment to be washed back into the Elbe river or the North Sea.
Over a million of tonnes of rock were brought in from Norway to build two dams of 6,700m and 2,500m length with their tops about 4,60m and 2m below waterlevel.

But by efficient cooperation and project management, we managed to complete the project within the limited timeframe of five months.”
