Configure your Dredge machine in PDS

It has just become much easier to set up your machine for your next dredging project.The Marine Dredge Configurator (MDC) is a new dredge machine configuration interface in Teledyne PDS. The MDC offers a step-by-step intuitive workflow to a configuration of a machine in a PDS project. Currently the Configurator is available for the cutter dredge, wire crane and excavator machines and additional machines are in the pipeline.

SeaBat T20 MotionScan

Tue, 17 May 2022 16:19:29 GMT

The SeaBat T20 MotionScan is a pan configuration, based on the renowned and compact SeaBat T20 high-resolution multibeam echo sounder. Installed on a dredge barge the SeaBat T20 MotionScan will, literally at the push of a button, map the work progress in seconds – saving contractors both time and money.
As a part of the modular SeaBat T-series, the T20 MotionScan can also easily be reconfigured to more traditional survey tasks.

Teledyne Z-Boat 1800T

Wed, 22 Jul 2020 22:33:21 GMT

THE TELEDYNE Z-BOAT 1800-T designed and manufactured by Teledyne Oceanscience, is a high-resolution shallow water hydrographic unmanned survey vehicle with an Odom Echotrac E20 Singlebeam Echosounder and dual antenna Trimble BX992 GNSS heading receiver. Each sensor is integrated into a compact, portable, and cost-effective package. The combination of Trimble's precise heading and positioning/guidance paired with Teledyne's accurate/precise sonars allow for best in class data collection under harsh conditions. This small unmanned vessel is ideally suited for a range of applications including Marine Construction and Dredging tasks.

DSC Vision: Revolutionizing Dredge Operations

Tue, 23 Jun 2020 16:29:58 GMT

Introducing DSC VISION, an innovative, user-friendly underwater visualization system that combines DSC Dredge software with Trimble GNSS positioning and Teledyne Marine sonar technology to deliver a single, powerful tool that enables operators to see and react to the work area below the dredge in real-time, allowing even new operators to dredge with an unprecedented level of accuracy, confidence, and efficiency.

The Technological Evolution of Dredging

Wed, 15 Jan 2020 13:10:31 GMT

From its inception in the late 1800's, the hydraulic, or pipeline, dredge has been the dominant machine used for near-shore and in-shore sediment transportation in the United States. These dredges were initially deployed to maintain sufficient channel depths to facilitate river navigation, port access and development. Infrastructure development after World War II created an inland market for sand and gravel mining dredges used in the production of concrete and asphalt. This material dredging market is at least an order of magnitude larger than the navigational dredging market in the US. Other public and consumer concerns, such as environmental remediation and coastal restoration, have created niche dredging strategies and equipment.

Hydraulic dredges have evolved from steam powered, manually controlled devices to sophisticated, energy efficient machines designed to present minimal negative effects on the environment. The equipment being manufactured today incorporates advanced algorithms to predict pipeline lengths, elevations, particle grain size, and required transport velocities. Many of these machines assist the operator in controlling the dredge's navigational path and speed as well as the production rate. In the next several months, several dredges in North America will be deployed with autonomous capabilities that include artificial intelligence and real-time sub-surface imaging and mapping with the primary goal of increased efficiency with less risk.

Teledyne RESON SeaBat T-Series Multibeam Sonars and Turbidity in Real-Time...

Fri, 10 Jan 2020 15:14:10 GMT

During most dredging operations, survey verification of having met grade and other contract requirements comes after the dredge has completed its work in a designated work area and hence moved on. What if the post-dredge survey reveals that the dredge has not fully met contract obligations? When this happens, the additional time, effort and expense to get the dredge back into position to remove what was missed can undermine the success of a project. What if the dredge operator could have “eyes under water” and confirm that grade requirements have been met before moving on?

During dredging operations, the material on the bottom is disturbed and released into the water column. Turbidity is a measure of the presence of suspended particulates. The more suspended solids in the water column, the higher the turbidity. High turbidity can create issues for sonar performance in that the suspended solids act as an acoustic reflector.
As barge mounted sonars are being used in the marine construction industry more frequently, dredge operators are considering the use of sonar to provide information in advance of post-dredge surveys. The “As-Building” benefits can be substantial but there is a concern over the effect turbidity can have on the acoustics.

Utilizing the Teledyne RESON SeaBat T-Series advanced bottom tracking abilities in various dredging operations, with varied levels of turbidity, we have begun to both demonstrate the value and quantify the limits of sonar usage during dredging operations. This presentation presents our results thus far.
