Damen DOP250 Creates New Island in Haringvliet

Damen Dredging Equipment was once again put to the test during a land reclamation project in Haringvliet, the Netherlands, for the contractor Martens en Van Oord.

The Haringvliet – a large water body just south of Rotterdam – was closed off the North Sea in 1970 to protect the Low Lands.

Recently, the locks – which have remained closed for decades – have been opened partially. The main reason for opening the sluices is the improvement of the water quality and the altered pattern of silt deposition.

The now brackish Haringvliet required adaptations for the wild life. The area is re-known for the large flocks of migratory birds stopping over on their journey from Northern Europe to Africa. For these birds a new stopping-off point has been created: an artificial island as a bird sanctuary.

For newly created island 5.000m³ of coarse sand had to be transported. This new island is located in a very shallow area the sand barges could not reach due to their draught. The creative solution was using a DOP250 submersible dredge pump to bridge the gap.

The DOP250 was connected to a pontoon-based Caterpillar 374D LRE excavator. A carousel of sand barges was moored alongside. Sufficient transport water was added to the cargo, creating a mixture which could be pumped out easily.

The DOP250 was lowered into the sand cargo, emptying the barge and pumping the coarse sand over some 300 m to the new isle through a Di 250 mm pipe line.

3rd International Congress Hydraulic Engineering Structures and Dredging

Russia’s leading maritime industry Media Group PortNews (www.portnews.ru) holds a traditional annual Congress “Hydraulic Engineering Structures and Dredging” in Moscow. 

The two-day Congress includes the 7th International Forum of Dredging Companies and the 3rd Technical Conference “Modern Solutions for Hydraulic Engineering”.

Infrastructure development is among the real sources of Russia’s economy growth. Construction of port facilities and new hydraulic engineering structures on the country’s inland waterways constitute an essential part of all infrastructure projects. It is important to take into account the best international practices to implement these projects effectively.

The program of the Congress will be devoted to the latest technologies for dredging and hydraulic engineering works. Speakers and delegates will refer to real projects to discuss specifics features of dredging works, as well as dedicated fleet and equipment involved.
