In 2012, the Loup Power District commissioned its new electric-powered DSC dustpan dredge, the Pawnee II, and retired the dredge it had been using for the past 75 years. As you can imagine, technology had advanced significantly since the early days of the original Pawnee, allowing the crew modern amenities and computer-based technology.
In 2007, the city of Villahermosa in Tabasco, Mexico, experienced a devastating flood. Since then, the federal and state governments—with the assistance of private industry—have launched a program designed to help prevent future flooding in and around the city.
The Gila River in Arizona is a very important source of irrigation water for the entire Gila River area south of Phoenix, including the Gila River Indian Community, but it carries quite a bit of sediment, which can cause blockage and separation. The San Carlos Irrigation and Drainage District (SCIDD) addressed the sediment problem by redirecting the river water through the 1,800-foot long, 100-foot-wide Florence-Casa Grande Canal, near Coolidge, Arizona, where the sediment was then trapped in a 15-foot-deep settling basin.

With energy costs soaring and spoil areas shrinking, transporting dredge slurry at the optimum flow rate and concentration is paramount.
Many factors contribute to limitations in the throughput of cutter suctions dredge. While most performance data available from cutter suction dredge manufactures outlines theoretical design throughput, others factors need to be considered when computing expected throughput.
Over the past 10+ years, many new products have entered the market that also apply to the dredge manufacturing processes. Original Equipment Manufacturers (OEM's) are spending more money and time into Research & Development to explore increased efficiencies, longer life and more affordable components. As these new components find themselves available for sale in the marketplace, they offer benefits to end users in many industries.
This paper will take us through the steps involved in the design and manufacture of the deepest mining dredge in the Western Hemisphere.
Japaul Oil and Maritime Services PLC (Japaul) is a rising star in the Nigerian dredging industry. Over the past several years, foreign dredging contractors have been replaced with Nigerian contractors, who have been busy updating their dredge fleets. Jegede A. Paul, Managing Director/CEO of Japaul, already owned dredges from Korea and Holland, and had previously taken delivery of his first DSC Shark (an 18-inch x 16-inch configuration) in 2007. Although the unit was used, DSC provides OEM parts information to all customers as an added benefit. Additionally, Mr.
DSC is proud to announce the launch of a new 22-inch x 20-inch Custom Electric Marlin class, self-propelled, hydraulic cutter-suction dredge at Arkhola Sand and Gravel’s operation in Fort Smith, Arkansas.
