Tunnels and bridges

Top-class tunneling

Øresund tunnel, Denmark-Sweden

The Øresund Tunnel covers a distance of more than 3.5 kilometers and is part of the direct link between Copenhagen in Denmark and Malmö in Sweden. The Scradeway installed gravel foundations on the trench bottom with extreme precision.

Coatzacoalcos, Mexico: first immersed tunnel in Latin America

In 2013, in Coatzacolacos on the Gulf of Mexico, Boskalis Dragamex completed the construction of the first immersed tunnel in Latin America. The project involved building a 700-meter-long, four-lane tunnel link.

Warnow Tunnel, Germany

Boskalis was responsible for the dredging, backfilling and rock protection works. The immersion of the elements and the installation of the foundation bed was carried out in joint venture.

Early works for LNG plant, Brass Island

The Brass LNG Project’s objective is to construct a LNG Complex on Brass Island, Bayelsa State, Nigeria, and in so doing, develop Nigeria’s abundant gas resources, reduce the adverse effect of gas flaring on the environment, and provide social-economic benefits to the local and wider Nigerian communities. The LNG complex will be designed to produce approximately 10 million tons per annum (MTPA) of LNG, as well as LPG and Residual NGL products.

Dredging and reclamation, Port of Peterhead

The project consisted of capital dredging, reclamation, quay construction and breakwater extension works for Peterhead Smith Embankment Development, in order to develop the area in the north of the harbour at Smith Embankment to provide sheltered berths for vessels ranging from 20 to 160 m in length.

Creation bird island, Le Havre port 2000

Le Havre is the fifth largest container port in Europe and is expanding its facilities: the current 14 quays for container vessels are to be expanded with another 12 (all outside the locks). Port 2000’s rationale centres on Le Havre’s determination to position itself as a leading hub.

Port expansion, Balboa

The plans to expand the Panama Canal represent one of the most important infrastructure improvements of the 21^st century. Since its opening in 1913 the Canal has provided the shortest and most economically viable shipping route from Pacific to Atlantic seaports. With the ever-increasing size of modern-day vessels, it was inevitable that the Canal would need to be widened and deepened. The expansion of the Canal has made the extension of the Port of Balboa at the mouth of the canal on the Pacific Ocean a necessity. The Phase 4 projects included Marine Works and Civil Works to improve two existing berths and to build a completely new berth capable of handling not only Post Panamax but also Super Post Panamax ships.

Land reclamation, North Manama Causeway

The purpose of the project was to provide additional land to accommodate a section of a proposed new highway system to service the area and to relieve congestion on the corniche road. Boskalis appointed Hydronamic (the in-house engineering department of Boskalis) to provide detailed design and on site assistance with supervision of the sub-contractor for the rock works.

Reclamation, dredging and excavation, The Wave

Through Orascom, the Omani government is developing their tourist and real estate sector in order to diversify its economical drivers. The Wave, Muscat is the first freehold tourism and residential development to be launched in the Sultanate of Oman. The USD 805 million project will stretch along 7 kilometers (4.35 miles) of beachfront land overlooking the Gulf of Oman and covers an area of approximately 2.5 million square meters (26.9 million square feet).
