Dredging Services
Dredge America, Inc. is a professional, reliable and innovative leader in delivering portable hydraulic dredging services that exceeds our clients’ high expectations, making us "the clear choice™" for your next project. We perform our dredging services for customers throughout the United States and North America. Projects outside the U.S. in the western hemisphere are considered on a case-by-case basis.
Dredge Guidance & Tracking Capabilities
In support of its dredging operations, Dredge America owns and operates industry leading hardware and software systems which include HYPACK’s DREDGEPACK and HYPACK MAX software packages, Trimble Navigation differential GPS (DGPS) and real time kinematic (RTK) capable GPS receivers and Teledyne Odom echo sounder.
Hydraulic Dredging
A progressive and high-tech solution for removing sediment from the lake bottom is through portable hydraulic dredging.
A hydraulic dredge floats on the water and excavates and pumps the material through a temporary pipeline to an offsite location, often several thousand feet away. This dredge acts like a floating vacuum cleaner that can remove sediment very precisely.
With a hydraulic dredge, the dredge discharge line and return line are the only obstructions in the environment. The lines are usually laid on the ground surface. Other than this, the dredge, which is not much larger than a boat, is the only machine to be seen. It is a very unobtrusive method that does not require disturbing the shoreline and only requires one trip in to put the dredge in the water and one trip out when the project is complete.
Hydraulic dredging provides the cleanest and least obtrusive method for sediment removal without damaging the sensitive environment.
Mission Lake: Hydrographic Survey Example
This software and hardware combination affords us dredge guidance / tracking capabilities and supports our in house bathymetric data collection efforts as well. More specifically:
DREDGEPACK coupled with our Trimble GPS receivers provides real-time positioning and guidance to our dredge operators. Incorporating dredge limits and design grade information, the systems allow our operators to maximize productivity by dredging efficiently, within limits and to grade without over-dredging or operating outside of project limits.
DREDGEPACK reporting capabilities allow us to monitor and report progress on a regular, automated basis. Up-to-date progress status is always available by utilizing the “matrix file” update functionality within DREDGEPACK.
HYPACK MAX is used on-board our custom-built survey vessel along with Trimble GPS and our Teledyne Odom echo sounder to collect hydrographic survey data. Pre- and post- dredging survey data collections allows us to better plan and execute our dredging projects and offers an extra measure of quality control throughout the life of a project while minimizing the need for, and costs incurred by, utilizing outside sources for hydrographic data collection and reporting.
