Van Oord wins Averijhaven silt removal deal

Van Oord has won a contract to design and carry out the removal of silt from the Averijhaven depot in IJmuiden.

After the removal of the contaminated silt, the area will be developed into an energy port.

The contract has a value of EUR 18 million and preparations will start in the spring of 2021.

The Averijhaven is located adjacent to the shipping route in the direction of the sea lock at IJmuiden and the Tata Steel site.

For a long time, it served as a dredging depot for Rijkswaterstaat, but was no longer used in recent years.

However, with the removal of the silt, the Averijhaven is being prepared for its new role as an energy port. This new port will be an important operating base for the construction of offshore wind farms.

For this remediation project, Van Oord will be deploying a cutter suction dredger (CSD).

Further, the CSD will transport the silt from the depot via a fully enclosed system to a transport vessel. This vessel will then transport the material to the Slufter depot.

During the work, the stability of the ring dike will be monitored by means of a measuring system.
