Every dredging system is designed for optimum site and project conditions to deliver maximum productivity and system efficiency. The local/international legislation will also govern the type of dredging in those waters. This may be cyclic or periodic in nature.

The primary objective here is to maintain the desired bed configuration or channel properties. Maintenance dredging: This is used to describe dredging, which is repetitive over a given time.These works primarily involve the payment of a single capital sum, hence the name. The formation of a new bed configuration in terms of orientation, width, depth, and susceptibility to erosion due to currents. Capital dredging: This dredging normally denotes projects which involve dredging as a one-off operation.In terms of project descriptions, dredging is usually categorized as: The dredged material extracted may be used for other projects/operations as per the excavated material properties. the process is a combination of excavation, transportation, deposition of the dredged materials.

However, the natural phenomenon of sedimentation over the water floor and movement of the silt affecting the effective water depth are a constant challenge to these channels, which led to the conceptualization of what we call ‘ Dredging‘ for removing these unwanted sedimentations and deposited foreign materials (ropes, chains, nets, rocks, and garbage) to ensure these channels are operable.ĭredging is the process of removing deposits settled at the floor of a water body utilizing mechanical operations using marine dredgers. Dredging may be done to clear the channel for marine vessels to transit or any civil construction projects and parts thereof. Deeper and wider water channels mean bigger ships transport more goods and people.
