This electrically-driven 8” dredge system allows the excavation of seabed sand, gravel, clay and rocks up to 140mm (5.5”) in diameter.

Regardless of the dredge size chosen, the UCS electrical dredge system utilises a reduced deck footprint by removing the need for large hydraulic umbilical reels and power units as required by hydraulic dredging systems. Replacing hydraulic hoses with an electrical umbilical eliminates the considerable power losses associated with transferring hydraulic oil through long hose lengths. The use of electric power also negates the risk of environmental damage due to oil leakage or loss. As a result, UCS systems offer superior suction and efficiency compared to hydraulic dredges.

Our standard offering comprises of an umbilical winch, skid unit, 10m suction hoses and spares package, with bespoke revisions also available.
