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.

Coastal protection, St. Petersburg

St. Petersburg is a UNESCO World Heritage City, but its location along the River Neva means that it has been threatened by over 300 floods since its founding by Peter the Great in 1703. The completion of the new 25 km long storm-surge barrier across the Gulf of Finland ensures that the city will no longer be vulnerable to high tides and devastating floods. As a result of the new Flood Protection Barrier, however, the old winding access channel had to be replaced with a new, straighter, more easily navigable channel.

Cleanup, Zellingwijk area

The Zellingwijk quarter of the village of Gouderak was built in the middle of the last century. In the early 1980s it became clear that the soil underneath this residential area was heavily contaminated as a result of the dumping of waste - mainly mineral oils and pesticides. The homes built on the site were subsequently demolished in the mid-1980s. Pending definitive remediation work, a layer of concrete / asphalt was applied to seal the site.

The archipelago consists of some 30 islands with a total of 160 km of shoreline and has a population of 800,000. Whereas the surface of Bahrain in the year 1960 was around 650 km2, the last decennia have seen a steady increase in the surface till a respectable figure of 740 km2 in 2007. This increase has been achieved by a various number of small and mayor reclamation projects.
