The UCS electric driven 8in dredge system allows the excavation of seabed sand, gravel, clay and rocks up to 140mm (5.5in) in diameter.
The advantages of the UCS electrical dredge system is that only a small deck footprint is required by removing the need for large umbilical reels and hydraulic power units as required by hydraulic dredging systems. More importantly, by replacing hydraulic hoses with an electrical umbilical eliminates the huge power losses associated with transferring hydraulic oil over long hose lengths. This makes the UCS systems suction and efficiency superior in performance over hydraulic systems.
The complete standard system comprises of the umbilical winch, the skid unit, 10m suction hoses and spares box. Additional suction hose lengths can be supplied in 10m sections. A “Halo” suction ring can also be supplied for drill cutting dredging.
