Damen DOP200 proves success at Swedish Port of Gothenburg

At the moment, a mayor port expansion project is underway at the Swedish Port of Gothenburg.

The expansion will result in an additional 220.000m2 of terminal surface and 460m more quay length.

The project has been divided in various stages: the DOP200 has proven its worth in the later stages of phase 1.

Now, the site has to be filled.

To do this, 350.000m3 of soil will be dredged from the local river, “Göta Älv”. Part of these sediments, some 175.000m3, have been contaminated over the years by for instance anti-fouling paints.

The dredging project has two gains:

  • the river is cleaned removing the contaminated soils,
  • these sediments are re-used to fill the expansion site.

The DOP200 is used to empty these barges at the highest possible mixture concentration. The dredge pump will, when required, use some water on its suction head to create a sufficiently fluid slurry mixture to be able to pump it.

The DOP200 is powered by a Damen powerpack, type PP400.

The dredge pump will deliver the dredged mixture to a processing plant through a cleanable screen container where large debris is taken out.

These materials will be pumped to the site where it will be covered with a 0,6 meters of crushed stone as base for the new terminal.

The expansion project – to be completed in 2024 – will add a surface of some 30 football pitches to the Port of Goteborg, its largest development project in the past 40 years.
