Royal Boskalis Westminster has been awarded two contracts in Finland with a combined contract value of €32 million.
Working for the Finnish Transport Infrastructure Agency, the Port of Helsinki and the City of Helsinki, Boskalis will deepen the Port's Vuosaari fairway and harbour basin from 11m to 13m and beneficially re-use a portion of the dredged material for the development of Helsinki's Hernesaari area, close to the city centre. The works have already commenced and are due for completion by the end of 2021.
For the harbour deepening works, one million cubic metres of clay and moraine material will be dredged and 0.8 million cubic metres of rock will be removed from the seabed by means of drilling and blasting. Part of this material will be transported by vessel to the Hernesaari area and reused for the reclamation of six hectares of land on which offices and residential housing for 7,000 people will be developed. For these activities Boskalis will deploy a variety of specialised dredging equipment including two large backhoe dredgers, a grab dredger, a drilling barge and various hopper barges.
Such projects are largely driven by growth in global trade and the trend towards larger vessels with deeper drafts as well as population growth in major cities.
