Dredging works to help facilitate wastewater transport from Sweden’s Hano island
Danish marine projects company Rohde Nielsen has completed dredging works related to the transport of wastewater from Hano island to a treatment facility on the southern Swedish mainland.
The contract scope on behalf of local client NCC comprised dredging a six-kilometre-long trench, at water depths from three to 30 metres. The backhoe dredger Mjolner R executed the dredging in the shallower sections while the offshore multipurpose vessel Heimdal R worked in the deeper areas.
All the installation works in the trench, including pipe- and cable lay, were executed by Heimdal R. Backfilling was also completed in all trench sections.
