Not many people understand the importance of dredges, the major role that they have played in the development of the world’s economic trade system, and the role that they continue to play in our global economy. However, dredges are used for a number of essential processes such as waterway navigation, aquaculture, environmental remediation, land restoration, land development, and many other applicationsincluding mining.

The Lake Panorama Rural Improvement Zone, located in Panora, Iowa, about 45 minutes west of Des Moines, maintains the largest private lake in Iowa. With 1,400 acres of lake surface, more than 30 miles of shoreline, 1,000 homes and approximately 200,000 to 300,000 cubic yards of silt to dredge each year, Lake Panorama was in need of upgraded equipment to meet the specific dredging needs of the area.  

Barrick Gold Corporation is a global company, located on five continents and involved in projects such as mine operation, advancing exploration and project development. The company acquired the mining rights to the largest operation in Pueblo Viejo, in the Sanchez Ramirez Province of the Dominican Republic. The mine was an open-pit operation, which produced minerals such as gold, silver, copper and limestone.

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.
