Construction
and maintenance
of ports

Boskalis has extensive experience constructing and maintaining ports and waterways worldwide. Our activities include dredging port access channels, inner channels, turning basins and mooring berths and constructing breakwaters utilizing our versatile fleet of trailing suction hopper dredgers, cutter suction dredgers and backhoes. Where additional land is needed for port development, we reclaim harbor islands and land for yards and terminals. In addition, we construct quay walls and offer soil improvement by compacting and vertical/horizontal drainage.

Bringing your project to a safe haven

Constructing ports involves a lot more than just hydraulic engineering. We also conduct detailed technical and financial feasibility studies for each project, and can assess and monitor your project’s environmental impact and by applying our building with nature techniques even assist in overcoming environmental concerns. We can take care of ongoing maintenance, which can also be taken into account during the construction process. In this way we bring even the most complex project to a safe haven.

Project highlights

Co-creation in Brazil

From 2011-15, Boskalis was involved in the construction of one of Latin America’s largest port-industry complexes in Rio de Janeiro, Brazil. Boskalis dredged two huge access channels, a turning basin, an inner channel, mooring berths and constructed revetments for the breakwater and over 13 km of access roads.

Construction of
Marker Wadden

Boskalis has been awarded the first phase of the Marker Wadden development in the Netherlands. The project includes the construction of an island with underwater landscaping. The Marker Wadden are natural islands that will be developed in the Markermeer lake in the years to come. They will provide a major boost for the ecological quality of the Markermeer lake. The natural shores of the islands will give fish more opportunities to spawn and feed. As a result, large numbers of birds such as terns and waders will return to the area because there will be more food for them. The construction of the Marker Wadden will transform the map of the Netherlands.

Outer harbor channel widening, Adelaide.

The Port of Adelaide is the primary port in South Australia, located at Outer Harbor. The port is operated by Flinders Ports Pty Ltd (Flinders Ports) and handles both container and cruise vessels, contributing significantly to the State’s economic activity. Flinders Ports identified the need for an upgrade of the existing infrastructure driven by the emergence of Post Panamax class vessels. To meet this growth the existing channel had to be widened to accommodate vessels with a maximum width of 49 m without operational restrictions. Flinders Ports contracted Boskalis to execute the dredging works.
