In calculating the booster pump’s location, elevation must be taken into account. The rule-of-thumb is that every 5 ft. of pipeline elevation is equivalent to approximately 100 ft. of horizontal distance. A 1,500-ft. pumping distance with 50 ft. of elevation is equal to pumping material 2,500 ft. horizontally.

As a dredge moves farther away from the discharge point, the pump speed is increased to maintain a proper slurry velocity within the pipeline. Once maximum pump speed has been achieved, further increasing the discharge distance causes the cost-per-ton of material moved to rise, while production declines. Of course, there is always a cost involved in pumping the water/material slurry and the associated fuel or power required to do so. Because of this, the idea of adding a booster pump to the dredging operation in order to reduce costs may seem counterintuitive.

A Nigerian contractor purchased a second 18-inch x 18-inch Marlin Class dredge, along with a DSC multipurpose workboat, after its original DSC dredge provided excellent service at the lowest cost of operation. The Marlin Class dredges were primarily needed for channel dredging, land development and reclamation, as well as mining sharp sand out of the Nigerian rivers.

Dredging impacts our lives. Dredging is an excavation activity usually carried out underwater and out of sight. It nearly always involves gathering sediments from the bottom of a pond, lake, river or harbor and then disposing of these materials at a different site. While not particularly glamorous, dredging affects our everyday lives in ways we may not even realize. Dredges are used in a variety of applications that include marine construction, environmental remediation, aiding navigation, mining, aggregate processing, recreational improvement, beach and land restoration and even by municipalities.
