Dredge - powerful machines used to remove earth and
other sediments from the bed of a body of water.
and lift the material mechanically by means of buckets or scoops.
Dustpan - hydraulic, self-propelled dredge that uses a suction mouth, shaped like a large dustpan or vacuum
cleaner, fitted with water jets for dislodging material from the bottom of the channel.
Hopper - self propelled floating plant which is capable of dredging material, storing it onboard, transporting
it to a disposal area,and dumping it.
Nonconventional type - type of specialized dredge which combines the features of hydraulic and mechanical dredges.
Pipeline - a hydraulic dredge whose prime function is to excavate and move material hydraulically to another
location without rehandling. Hydraulic dredging requires dilution with water for material pickup and transport through
a pipeline to a disposal location.
Side caster - self propelled trailing suction dredge that discharges material to one side of the excavation through
a suspended discharge pipe.
Water Injection - A type of dredging in which water is injected at high velocity and/or volume, into the shoaled
material to enable it to be moved to a deeper area by the current.
All Types - combination of three or more types of dredges.
Pipeline & Bucket - dredging project which uses a pipeline and a bucket dredge.
Pipeline & Hopper - dredging project which uses a pipeline and a hopper dredge.
Hopper & Bucket - dredging project which uses a hopper and a bucket dredge.
