Dredging & Marine Construction

Marine Construction & Dredging Application

Marine dredging is the process of excavating and removing material from the bottom of an ocean, river, pond, or other large bodies of water. Dredging is mainly used for marine construction projects, mining, sediment removal, environmental remediation, canal deepening, harbor maintenance, and many more.

What is Dredging?

Industrial dredging is the process of removing sand, silt, and other solid material from the bottom of large bodies of water by using any combination of dredge pumps and material agitators or through mechanical means such as clamshell buckets. Dredging is a major service component in many major underwater construction projects to create a flat and stable foundation on the seabed. In addition, dredging is also used to maintain harbors, canals, rivers, lakes, and other bodies of water to ensure boats and large ships are able to safely pass without getting stuck in sediment build-up which occurs as sand and silt wash downstream, eventually clogging up channels and harbors. Periodically, this accumulation of material must be excavated and transported away by dredging due to large ships requiring a certain depth of water to remain operable.

• Mine Tailings Dredging

Problems Facing the Dredging Industry Today

There are many problems that face the dredging industry ranging from equipment problems to environmental effects. The main challenges with traditional dredging are:

The dredge pumps routinely get clogged with sand, silt, and other debris
The dredge pump and impeller are quickly worn down by abrasive materials
The dredge pumps fail more often
Longer downtimes for pump maintenance which halts production and hurts your bottom line
Ecosystem and environmental damage stemming from high turbidity or mechanical dredging
