Design and construction harbor channel, Sydney harbor

The 'Sydney Harbor Channel Dredging Project' in Nova Scotia, Canada, involved dredging and reclamation work as part of the construction of the new Sydney Port container terminal located on the northeast coast of Canada. Once operational, Sydney Port will be the most northerly deepwater container terminal on the North American east coast.

The project required the creation of a 12km access channel, for which approximately 4 million m3 of sand and silt was dredged. This material was then taken to a confined disposal facility (CDF) forming the foundation of the future terminal. The CDF was constructed by Boskalis and engineered by Hydronamic, the Boskalis engineering consultancy.

Project specification

  • Detailed design of CDF
  • Debris and wreck removal in access channel, construction of CDF, including the installation of 80,000 t of filter material (10 - 100 kg rocks)
  • and 130,000 t of armor rock (0.1 - 3 t rocks)
  • Deepening of existing natural harbor:
  • dredging 3.3 million m3 of sand and gravel and 0.9 million m3 of mud
  • Disposal of dredged material in CDF
  • Execution of environmental monitoring and other environmental control measures.

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.
