Cutter Suction Dredge

Cutter Suction Dredge

Designers: Alluvial Dredges

Client

Andrade Gutierrez

Location

Construction: Brazil Operation: Brazil

The cutter suction dredge was designed to strip barren overburden to a depth of 14 metres below the waterline. The dredge is powered electrically by a 4160 volt, 3ph, 60Hz. supply from the shore and is capable of dredging 700 cubic metres of solids per hour, at a slurry concentration of 25% by apparent volume and delivering the material through a discharge pipe line 1000 metres long with a 4 metre elevation.

The submerged ladder pump, because of it’s position, eliminates priming problems and is capable of pumping at concentrations up to 70%.

The cutter and winches are designed with an additional 20% excess reserve capacity.
