Dredging, as a process, is used to remove the deposits under water for the purpose of clearing the water pathway for ships to pass, to create adequate space to construct important bridges, dykes and dams and to weed out silts, in toxins and pollutions from the bottom of the water. Without application of dredging we will not be able to channelize the construction of the requisite edifices properly. Only by making the right use of dredging tools and by dredging the amount of underwater silts and compositions quite a number of excellent constructions have been carried out so far.

Dredging is an escalation activity used to remove sediments and debris from the bottom of lakes, rivers, harbors and water bodies. It has become a routine in all waterways around the world because sedimentation which the natural process of sand and silt washing downstream gradually fills channels and harbors. This technique is often used to help waterways navigable.

The dredging activity becomes a challenge when called upon to tackle difficult bottom in maritime conditions and within demanding time frames. In this activity cranes ranging in different capacities and heavy duty buckets are employed to help the operator.

Pulp and paper companies generate waste from their operation that is typically comprised of a mixture of liquid and solid materials. This sludge is pumped into on-site water treatment lagoons in order to allow further separation of water and solids. One of the most effective and efficient maintenance operation for pulp and paper lagoons involved dredging the lagoon to remove the sludge and then de-watering the sludge prior to deposit. There are two types of dredges manned and unmanned.  Manned or unmanned skilled dredge operators are key to ensuring safe and efficient dredge operation with no risk to lagoon aeration systems.

Job Opportunities

The dredge operator is a profession in the construction category. The openings include crane operators, marine scientist, heavy equipment operator, civil engineer, material inspector, project coordinator, construction manager and shift super

Mechanical dredges vs. hydraulic dredges

Mechanical dredges work by mechanically digging or gathering sediment from the bottom surface of a body of water, typically through the use of a bucket. Hydraulic dredges on the other hand work by sucking up a mixture of sediment and water (known as slurry) from the bottom surface and then transferring the mixture through a pipeline to another location. Hydraulic dredging is less expensive, faster and safer than mechanical dredging.
