Julong Environment Technology has successfully delivery one set full electric 14/12” cutter suction dredger (CSD300E) to a contractor from the European Union.
According to Julong, the CSD already started the sand mining operations.
The dredger is fully controlled by Simens PLC control system. The dredge pump is driven by 355kw marine electric motor through frequency converter, and the cutter head, winches, spuds are driven by separate 120kw marine electric motor.
With electric motors powering the dredge system, the CSD300E makes zero emissions during the dredging works.
The electric power provides a significant reduction in noise, adding an extra tier of sustainability and ensuring the dredger’s suitability for projects in densely populated and environmentally sensitive areas, Julong said.
“Another advantage is that the operational costs of electric dredger are much lower when compared with other kinds of dredging equipment,” the sales director Mr. John Xiang said.
The electric driven CSD is a modular dredger, dismountable for transportation by road, allowing easy assembly in remote locations.
The dredger’s low voltage system equals easy maintenance with no requirement for special crew training.
Also, the associated reduction in vibrations during dredging ensures a comfortable experience for those on board, Julong said.
