Dredging Up Power
Caterpillar Marine was selected to power three 3500 m³ trailing suction hopper dredgers for the Jan De Nul Group with Cat 3500E IMO III and EPA Tier 4 certified engines. Cat said the 3500E incorporates selective catalyst reduction (SCR) after-treatment technology with closed-loop NOx sensing and application optimized performance for minimized owning and operating costs. “Embedded in the Caterpillar design philosophy and business model are two main value drivers — highest uptime and lowest total...
Case study - Control of dredging works in the Danube River - Austria
The Austrian waterway management has introduced an automatic system to monitor a series of barges, which calculates the dredged material as a basis for handling invoices of the dredging companies. Before converting to a remote data transmission option, all calculations were entered manually. The datalogger saves the cost for hand-writing documentation of the dredging works by external staff and guarantees an automatic and standardized procedure of cubature calculations.

Ceresco Dam Case Study
Global was contracted by Terra Contracting Services, LLC to serve as Water Treatment Specialists in response to the 2010 Enbridge Oil Spill along the Kalamazoo River. An energy pipeline rupture caused 877,000 gallons of heavy crude oil to spill into Talmadge Creek in Calhoun County, Michigan, which flows into the Kalamazoo River. Global engineered a processing plant for material and slurry dredged from the region upstream of the Ceresco Dam. Material and slurry were pumped from the 4 dredges to the 14 acre...
Panama Canal: Boat Towed 3D Resistivity Surveys - Case Study
The Panama Canal Authority (ACP) needed to expand the canal in order to accommodate larger ships (and more traffic)—but first, they needed to know two things: what types of sediment loads needed to be dredged out—and more importantly—how much these loads would cost. That’s where AGI marine resistivity imaging methods come in. For two months in 2008, a team used boat-towed streaming marine resistivity data to successfully estimate the geotechnical properties of the canal floor in order to...
Can’t Afford Pond Dredging? We have solutions.
Ponds and lakes naturally accumulate sludge and nutrients that lead to eutrophication and eventually pond or lake death. Natural succession is driving all lakes and ponds to become meadows and eventually forest. To slow or reverse this process and maintain a lake or pond beneficial microbes are critical. These beneficial microbes improve water quality by reducing nutrients and sludge through natural processes. Reduce Bottom Sludge Reduce Odors Reduce Suspended Solids Waste and Sludge Reducer™...
