APPLICATION SHEET

Clamshell Crane Dredge
TRIMBLE MARINE CONSTRUCTION SOFTWARE
Trimble Marine Construction software improves productivity and efficiency inunderwater construction applications. It provides accurate 3D visualization to assist
the operator with underwater construction tasks.
Efficient dredging

Real time seafloor and design

Trimble Marine Construction software forclamshell dredging applications is a powerfultool to help dredge operators improve
productivity and efficiency. The operator has areal time overview of the crane, tool and barge
in plan and profile views. Displays include thebucket position, bucket open/close status,
bucket depth along with the surveyed anddesign depths.

Up/down indicators show the operator theexact distance to the seafloor and design depth
during movement. The software supports
complex 3D designs.

Real time visualization and monitoring
Real time views of the dredger in plan andprofile view displays the clamshell, design
depths and color-coded Digital Terrain Model(DTM). The DTM highlights the high and low
spots relative to grade and is updated in realtime tracking the progress of the dredging work.
The update follows the shape of the clamshelland is visible immediately in all the views. Thesystem also shows the open/close status of thebucket. A built-in calibration procedure allows
for easy calibration of the cable counters.

TRANSFORMING THE WAY THE WORLD WORKS

Workflows
The software can also render views that show
the difference between the grid model and thedesign model to quickly locate areas in need ofattention.

Customizable interface
Multiple monitors with independent layouts
can be tailored to the needs of the dredge
operator. A color-coded plan view and 3D viewhighlights high and low spots. The surface
Digital Terrain Model (DTM) is updated in realtime registering the progress of the dredging
work showing depth, differential and production
models all updated according to progress of thecutter head.

About Trimble Marine
Trimble offers flexible, high-performance positioning systems tomeet the unique needs of marine construction on both simple
and complex projects. Solutions include both hardware andsoftware, and can be easily integrated into third-party systems. The
portfolio includes marine information systems (e.g. Trimble Marine
Construction software), GNSS receivers, antennas, radios, encoders, depth gauges
and inertial positioning systems.
Trimble Marine Construction software is transforming the way marine operations
work by helping build and maintain the world’s port, river, canal and other criticalinfrastructure. Trimble continues to transform this industry’s work across the project
lifecycle through sophisticated planning and design, advanced automation solutions,site positioning, and real time connectivity.
