The Russian Ministry of Transport and Port infrastructure has, through the principal contractor MOST, awarded a contract to DEME for dredging works that took 4 years. The contract was signed with ‘Mordraga LLC’, DEME’s Russian subsidiary. The contract comprised dredging work for the access channel and turning basin of a new service port on the Yamal peninsula. This port must serve hyper-modern, icebreaking LNG ships.
The dredging works started in 2014 and were completed in 2015. Dredging is only possible in the summer and only for 10 weeks.
The new project meant work for at least 250 people during 2 years. The gas will be transported from Yamal to two European ports, probably including Zeebrugge.
Sea channel and turning basin
DEME starts working on a 49km long, 295m wide and 15m deep (it is now 10m) sea channel. Together, the Sabetta Port turning basin and the access channel are 8km long, and the access channel will be 415m wide.
The Yamal peninsula
Dredging in the high north is an activity that has been tried and proven safe. In the 1980s, the first dredging works were already conducted above the Arctic Circle, among others in the Beaufort Sea in Canada.
The Yamal peninsula, situated in northwest Siberia, is some 700 kilometres long. It is bordered on the west by the Kara Sea and on the east by the Gulf of Ob. The port is located in proximity to Murmansk in Russia and Hammerfest in Norway, some 2,000 km south of the North Pole.
Environmental Management Plan
By means of the track record it has built up, DEME has intentionally positioned itself throughout the years as a green company. It develops projects for renewable offshore energy, tidal power and environmental remediation. For the company, sustainability is in line with its vision of new industrial enterprise.
The dredging activities along the Russian peninsula are therefore subject to the same environmental standards that DEME applies globally. As with many other projects, DEME has furthermore set up an Environmental Management Plan. The care with which DEME considers environmental implications was of decisive importance for the principal in the awarding of the dredging works.
Environmental Captain safeguards precautionary principle
DEME pursues minimal turbidity of the water. Nevertheless, it has developed a management plan in the event that something still goes wrong.
DEME is proud to announce a world’s first in having an ‘Environmental Captain’ – as an independent expert – who is responsible for all environmental-technical aspects of the project. There are specific precautionary measures in place with regard to the flora and fauna.
DEME utilises the precautionary principle. This means that nothing that the company could do for the benefit of the environment and safety will be omitted.
