Royal Boskalis Westminster has been selected by the Finnish Transport Infrastructure Agency to carry out dredging and reclamation works at the Port of Helsinki and within the city of Helsinki itself.
In the Port of Helsinki, Boskalis will deepen the de Vuosaari fairway and harbour basin from 11 to 13 metres and utilise a part of the dredged material for the development of Helsinki's Hernesaari area, which is close to the centre of the city.
The activities will commence immediately and are due to be completed by the end of 2021.
For the harbour deepening scope, a volume of 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 in the coming years.
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.
The dredging contracts have a combined value of €32 million (US$35.23 million).
