Ust-Luga Seaport Development 2010


DEME has been active in St. Petersburg and Ust-Luga since 2004. In 2006 and 2007, the company participated in the dredging of an access channel for the new flood protection barrier in St. Petersburg. And in Ust- Luga DEME has been involved in many dredging projects including work on the ferry, oil and general cargo terminals, the turning basin and the operational basins of the transhipment terminal and container terminal, as well as in the southern and northern access channels.

In addition to DEME’s Cutter Suction Dredger Vlaanderen XVI, the hopper dredgers Atlantico Due, Reynaert, Pallieter, Marieke, Brabo and Lange Wapper and the backhoe dredger Zenne have been dredging in the port of Ust-Luga.

During all these campaigns - in 2004, 2008, 2009 and 2010 - DEME has built up an excellent relationship with the client Northern Dredging Company (NDC), which is contracted by the end-client RosMorPort (the State Port Organisation).

The background to this project was that the Russian government wanted a port that could compete with others in the Baltic region and therefore, decided to develop Ust-Luga, which will be one of the largest ports in Russia when fully developed.

Our solution


During this particular campaign in 2010, DEME was responsible for dredging works of 3.5 million m³ of sand, 1.7 million m³ of which was dumped in the dumping area and the remaining 1.6 million m³ was pumped to a reclamation area. 

The Trailing Suction Hopper Dredger Lange Wapper dredged in the North II area situated in front of the oil terminal. The good quality sand had to be pumped hydraulically to shore via a floating and a landline to the reclamation area. Our client NDC then took over the mixture with its own landlines. If the quality of the sand did not meet the client’s standards it was dumped in the offshore dumping area.

After each discharge of the hopper dredger on the reclamation area, bulldozers and excavators started to disperse and handle the pumped material. The dewatering of the reclamation area was done by using  water boxes, which allow any excess water to flow back to the sea.

DEME’s survey vessel regularly carried out surveys of the dredge area and the data was brought on board the Lange Wapper. In this way the Lange Wapper was able to work in the most efficient way possible and DEME could make sure it fulfilled the client’s wishes.
