CCI Nantes Saint-Nazaire has invited bidders for the dredging works in the main channel to the Port of Pornichet.
These works include a basic solution, two variant solutions and two options:
– The basic solution is to dredge 35,000 m3 of sediment by hydraulic means, with the discharge of sediment to a discharge point located 2.5kms offshore;
– Solution variant 1 consists of dredging 35,000 m3 of sediment and dumping it at a disposal site located 6.5kms offshore;
– Option 1 is to handle a volume of 1,000 m3 of sediment which may contain hydrocarbons, for an in-situ upgrading to form embankments to create a confinement area within a median;
– Option 2 is to evacuate a volume of 1000 m3 of sediment likely to contain hydrocarbons to a centre of non-hazardous waste storage.
– Options 1 or 2 may complement the basic solution, or the Option 1 solution.
The two alternative solutions are to dredge and then treat 35,000 m3 of sediment which is likely to contain hydrocarbons.
The deadline for this tender is March 5, 2013.
