Maintenance dredging on Elbe 2013 - 2016

The Water and Shipping Authority Cuxhaven commissioned us from May 2013 to May 2016 with the maintenance of the officially stipulated navigable water depths and widths of the River Elbe. The stretch of river to be maintained is approx. 110 km between Wedel and Cuxhaven.

Preparations for work in Cuxhaven

The contract for this project is worth €75m. The dredge volume comprises approx. 28 million m³ of sand and mud. The dredge material is dumped at specially defined places along the River Elbe.



Based on the size of the river sections to be maintained, we use large and medium-large trailing suction hopper dredgers as well as several other smaller units from the Boskalis pool. 

The first work will be carried out using the trailing suction hopper dredger Barent Zanen. The Barent Zanen has a hold capacity of 8,116 m³.

Guaranteeing the right water depths is essential to allow shipping to reach the Port of Hamburg. The Port of Hamburg is Europe’s third largest port, after Rotterdam and Antwerp, and is a key transshipment location in Germany.
