Kra Canal (Thailand) excavation by nuclear-powered dredges
Partial excavation of a Kra Canal in Thailand by nuclear-powered cutter-head suction dredges is examined. Such automated digging by a floating machine is deemed economically and geologically feasible. International and intranational commerce will be benefited greatly as will the residents of peninsular Thailand. The 26 December 2004 tsunami (particularly at Ko Phuket on the Andaman Sea coast) ...

Dredging Short Courses
By Eric Lillberg, SRS Crisafulli Senior Applications Engineer When I first started as an applications engineer for SRS Crisafulli, I searched for information on the subject of dredging. I was surprised to find there was very little non-commercial content available. I have since found a pair of short courses, offered annually by Texas A&M, which I recommend highly to any professional ...

Four Major Benefits of Horizontal Hydraulic Auger Dredges
Horizontal hydraulic auger dredging has been around for nearly 50 years, but remains the unknown stepchild of the dredging world. That may be changing as environmental dredging becomes more prominent. Horizontal hydraulic auger dredges are ideal for environmental projects for several reasons. First, horizontal hydraulic auger dredges are small. I know everybody wants bigger, but small has ...

The Experts’ Views of Horizontal Hydraulic Auger Dredging
I attended the 42nd Texas A & M University dredging short course in January 2013. Despite the mountain of excellent information I gleaned from the course, I was disappointed that my dredging field wasn’t featured. Horizontal hydraulic auger dredging has been around for nearly 50 years, but remains the unknown stepchild of the dredging world. That may be changing as environmental ...

Rotomite 6000 dredge system - centennial coal-case study
Centennial Coal's Mannering Colliery mine averages over 1M tons of coal per year when operating at full capacity. The mine's run-off ponds' sludge issues prompted Centennial to contact Dredging Solutions, SRS Crisafulli's Dealer in Australasia, and an experienced dredging contractor. Dredging solutions deployed the Crisafulli Rotomite 6000 auger suction dredge system because of the equipment's ...

Hydraulic Dredging: A cost effective solution for most dredging tasks
The vast majority of dredging jobs require removal of solids to depths of 30 feet or less. Several features enable hydraulic dredges to be the solution of choice for these applications. First, what are hydraulic dredges and how do they compare with alternative mechanical dredge types? Hydraulic dredges create slurries, combinations of solids and water, pump the slurries to the surface of ...

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 ...
