Port development
and maintenance

Boskalis provides integrated solutions for a fully operational port - from the development of new ports to the improvement or expansion, maintenance and protection of existing ports. We cover all project phases from (pre-) feasibility and design through to construction, including dredging access channels, environmental monitoring, soil remediation and financing. We offer comprehensive infrastructure solutions (quay walls, roads, railways, tunnels and bridges) and have over a century experience in land reclamation to accommodate it. We also deliver cost-effective sea defense.

Port development – expertise managing complexity

Boskalis has a proven track record delivering complex port development projects. We use our vast experience and expertise to assess the economic and environmental impacts of your project, and manage the numerous disciplines and contractors involved in the design, planning and time-critical construction phase. We specialise in developing greenfield facilities in remote locations with limited access and infrastructure, and a heightened environmental focus.

Port protection – cost-effective, sustainable solutions

Boskalis designs, constructs and maintains breakwaters and revetments to protect your port. This may involve seabed preparation and rock installation. Our expertise in quarry management, logistics and in-situ production of concrete elements, enables us to optimize the construction process to deliver an integrated, cost-effective sea defense. Through our subsidiary Boskalis Hirdes, we can also remove unexploded ordnance.

Port infrastructure – streamlining execution

Ensuring excellent connections with the hinterland requires a wide variety of port infrastructure solutions. We streamline execution by managing subcontractors, communicating with stakeholders, eliminating interfaces and/or acting as a specialist subcontractor. We have the expertise to create new land required for development and new infrastructure.

Involve Boskalis early on and we can improve your processes, mitigate risks, minimize uncertainties and deliver the solutions you seek.

Sepetiba_aerial_header.jpg

Reclamation and dewatering works, Sepetiba Bay

The German steel-maker ThyssenKrupp Steel and the Brazilian mining giant Companhia Vale do Rio Doce (CVRD) teamed up to construct a EUR 3 billion steel factory at Sepetiba. This is a small town of 36,000 inhabitants near Rio de Janeiro with good access to the Atlantic Ocean. The new steel factory allowed Brazil not only to export more of its plentiful mineral resources, but also to produce semi-finished products that can be sold at higher margins. The government authorities of Brazil and Rio de Janeiro both supported the project.

Port development, Lerwick

The Port of Lerwick is situated on the east coast of the Shetland Islands, and is operated by Lerwick Port Authority. The 2008 dredging and reclamation works were one of the largest marine projects to be carried out in Scotland in recent years and constituted the largest single investment in the port to date.

Port construction, Vuosaari

Vuosaari Harbor is the most significant harbor project in Finnish history; in fact, it is unique even on a European scale. Both existing harbors in Helsinki’s city centre are being transferred to the eastern outskirts of the city. They are being replaced with a harbor with excellent traffic connections that can meet the increasing demand for cargo handling. The Vuosaari Harbor Center will provide a competitive and modern service package, with smooth connections between harbor operations and other logistical facilities. The harbor center will comprise the gate area, the closed harbor area and the adjacent Business Parks. The fairway to the Harbor Center will be 32 km long, at least 200 m wide, and 11 m deep. The port area comprises 150 ha, of which 90 ha will be land reclaimed from the sea.

Salvage operation, Mighty Servant 3

In the morning of 6 December 2006 semi submersible vessel Mighty Servant 3 developed a list and sank off the port of Luanda, Angola, after the offloading of drilling platform Aleutian Key. The vessel was resting at the sea bottom in approximately 52 meters of water.

Cleanup, Ketelmeer

Ketelmeer, a lake in the Netherlands with a length of some 10 kilometers and a width varying from two to three kilometers, separates the North Eastern and Southern Polders constructed during the late 1960s and early 1970s. It is a major example of the problem of 'historic pollution'. Lake Ketelmeer receives the waters of the Rijn and IJssel and over a period of three or more decades, tens of millions of cubic meters of highly contaminated sediments entered Ketelmeer from hundreds of upstream locations. The bottom was covered by polluted sediments to an average depth of 50 cm. A significant proportion of this material had to be removed, or capped by the cleaner sediments of recent years, if a normal aquatic environment was to be restored.

Land reclamation, Shaikh Khalifa Bin Salman Causeway

The Shaikh Khalifa Bin Salman Causeway is located in the State of Bahrain in an expanse of water called the Khawr Al Qulayah. It connects the Hidd Drydock Highway to the Mina Sulman Port. This major infrastructure project is carried out in advance of the planned expansion of the Bahrain port activities. This New Port project is planned at the Hidd side and via the Shaikh Khalifa Bin Salman Causeway direct connected with the existing Mina Sulman port and Saudi Arabia. The total length of the Shaikh Khalifa Bin Salman Causeway is approximately 6,500 m, including a bridge of 400 m, which was constructed in 2000.
