Tunnel construction Øresund, Denmark - Sweden

The Øresund Tunnel forms part of the Øresund Link that connects the cities of Copenhagen in Denmark and Malmö in Sweden across the Øresund.

europeThe Link, which comprises a motorway and a railway, consists of three different construction elements:

  • A man-made peninsula adjacent to Copenhagen airport (Kastrup) and a 4 km long man-made island (called Peberholm) located roughly in the middle of the Øresund;
  • The world’s longest immersed tunnel of 3,520 meters, positioned between the peninsula and Peberholm;
  • A bridge of 7.8 km length between the artificial island and the Swedish coast near Malmö.

The decision to construct the Link was taken by the Danish and Swedish governments after lengthy discussions, mainly about the environmental aspects of the works. The Link was built under design & construct contracts, and is operated by Øresundkonsortiet who charge a toll. The opening of the Link took place in 2000.

Expansion coal terminal, Muuga

The Muuga Coal terminal, sited on a bay, east of the existing port of Muuga, is to handle some five million tons of Siberian coal a year for destinations worldwide. The coal is shipped to Muuga by rail. Future developments may include container berths and steel facilities. The main contractor for the development of the Muuga coal terminal was the Estonian project management group A.S. Merko Ehitus.

Construction drilling island and ice barriers, Kazakhstan

Agip Kazakhstan North Caspian Operating Company B.V. (Agip KCO), a consortium of eight leading oil companies, is active in the northern section of the Caspian Sea. The gas and oil reserves in this area were mapped out in 1998 and 1999. To allow for their exploitation, Boskalis International has created an artificial island measuring 225 x 225 meters, and underwater berms, for Agip KCO. Four years later, the time was ripe for the construction of the drilling island and ice barriers. Once they were in place, Agip KCO could start to extract and distribute the oil reserves.

Port construction, Daya Bay

In Daya Bay, P.R. China, a USD 4.3 billion petrochemicals complex was being built by CNOOC and Shell Petrochemicals Company (CSPC). Daya Bay is located in the southwest of China, Huizhou Municipality, Guangdong Province. The project called for the construction of two marine facilities, one nearby the petrochemicals complex, the other one further offshore. Early 2004, the Boskalis International B.V. and Nanjing Changjiang Waterway Engineering Bureau (NCWEB) partnership commenced dredging for the CSPC Nanhai Petrochemicals project. Key requirement of the project was to preserve the sensitive environment in Daya Bay. Hydronamic, Boskalis’ own engineering consultancy, designed the required monitoring plan and took responsibility for its implementation.
