Damen Hands Over the CSD Amoris
The last week of November saw the hand-over ceremony of the Amoris cutter suction dredger (CSD). The one-off, built by Damen Dredging Equipment , has now arrived in Antwerp where it will work on the polluted silt treatment plant of SeReAnt. After a full programme of dredging tests, the Amoris has been handed over to its owners, and it has already started its productive life on the Antwerp AMORAS super project.
The building of the dredger has been completed in only fourteen months time, which was required due to the tight planning of the entire silt processing plant. Damen has succeeded in meeting this planning due to the excellent cooperation within the Damen Group. All design, dredging components and coordination work has been done by Damen Dredging Equipment. The hull has been built at the Polish Damen yard in Kozle. The completion of the dredger was done at another Damen yard, being Maaskant Stellendam.
Dredging Tool
The stationary CSD with its 450 mm discharge diameter, is a dredging tool designed to very specific customer specifications. During the design and building process Damen Dredging Equipment and SeReAnt cooperated closely to integrate all requirements in the dredger. The dredger is for instance fitted out with four spuds of which two are placed in spud carriages to ensure a continuous and smooth dredging process. The heavy duty cutter ladder swings by means of hydraulic cylinders, in stead of the traditional wide wire winches. The entire dredger including its dredge pumps is electrically driven. The dredge pump capacity for both the cutter action as well as the barge unloader is some 3.000 cu. m/h. The fully automated dredger features for instance dredge pump capacity control, swing ladder control, and automated coupling to the shore-based treatment plant.
SeReAnt & AMORAS
SeReAnt is a joint venture company in which Dredging International and Jan de Nul have combined the forces of their respective specialised environmental subsidiaries DEME Environmental Contractors and Envisan for the AMORAS project. The project covers the entire process from dredging in order to guarantee sufficient draught to shipping traffic in the Port of Antwerp for the coming decades, to responsible storage of the contaminated material of which high volumes have to be dredged and stored annually.
