Construction of Maasvlakte 2 has an impact on local currents

The construction of Maasvlakte 2 has consequences for the currents and waves in the North Sea. This in turn will have an impact on the maintenance of the fairways.

The cross-current in front of and in the port entrance is particularly important for safe access to the port. To predict the changes to the current around the new port, researchers conducted extensive simulation studies with the aid of computer models and manoeuvre simulators. They concluded that the land reclamation will result in more favourable current conditions in the Maasgeul fairway and the Maas Entrance (the port's entrance and exit). Within the port itself, the current will increase at a number of locations (Beerkanaal, Yangtzehaven). However, neither the ocean-going vessels nor the inland vessels will be hindered by this stronger current. Similarly, the wave conditions for shipping after the construction of Maasvlakte 2 will remain comparable to the existing situation.

Less maintenance

The construction of Maasvlakte 2 will also affect the silt deposits in the port. The water that flows through the port contains a lot of silt, both from the river upstream and from the North Sea. This silt is deposited in the port as a result of tidal movements. Each year, some eight million m³ of silt needs to be dredged out of the port basins to keep them at the correct depth. Research has predicted that after Maasvlakte 2's construction, the Maas Entrance and the port basins will silt up to a lesser extent and will therefore require less maintenance. The land reclamation will change the current pattern in front of the port. This will reduce the silt concentrations directly in front of the port entrance, particularly during high tide.
