Norwegian rehabilitation project
Treatment and remediation expert, Envisan, has won an important rehabilitation project in Norway which aims to restore the port basin to its desired depth and stop the further spread of contaminated sediments.
The project commissioned by city council and the port authority of Trondheim in Norway, is highly ranked by the Norwegian environmental authorities. Dredging activities will commence in spring 2015 and be completed by April 2016.
During the project, Envisan will mobilise a dredging barge to dredge 65,000 m³ of contaminated sediments in the port basin. The dredged sediments will partly be placed in an underwater cell and partly reused for land expansion.
The dredged zones will then be covered with a gravel layer to prevent further spread of the residual contamination.
Envisan is the environmental subsidiary of Jan De Nul Group. It specialises in the treatment, remediation and processing of sediments, soil, groundwater, waste and alternative raw materials.
The company is actively working on the sustainable development of ports, harbours and waterways concerning environmental dredging works, sediment treatment or redevelopment of contaminated brownfields.
