Optimize your dredging operation by using 3D software. A CEDA white paper by Corporate Member EIVA

Precision dredging in marine environments is a challenging task. However, it can be done in a safe and productive manner with the right tools. The operator must be able to see the bucket movement in real-time relative to the seabed and the design grade. The dredging platform is often not static, so sensors must also monitor the pitch and roll of the barge to effectively position the excavator bucket. Precise sensors and visualization software are essential components in a marine excavator or wire crane system doing this high precision work.

This paper introduces two cases of marine dredging operations using an excavator and wire crane, and describes how using 3D visualization ensured the optimization and a near instant progress reporting of the job’s progress. 

The first case covers the combination of EIVA NaviSuite Uca dredge software with Trimble GCS900™ sensors, and outlines how one of the users experienced an approximately 20% productivity gain while obtaining additional information on the progress of the dredging operation.

The second case covers the integration of EIVA’s dredge software with a wiring crane using a clamshell for dredging in deep water at the foot of the Norwegian mountains. This dredging contractor shared with the developers how this 3D view helped to keep the operation productive and provide confident results from machine data. Additionally, the challenges encountered during the system integration are also covered.

This paper will enable readers to understand the productivity benefits of using 3D software to enable the operator to see the progress of the dredging in real time. With better information being obtained during dredging operations, future projects can be planned more efficiently and progress can be tracked at every stage of a dredging project.

CEDA white papers are produced by CEDA Corporate Members. A CEDA white papers is a technical article that
provides detailed information about a product or service. While it has an objective, educational approach – contrary to conference papers that must avoid commercialism - White Papers contain persuasive information to lead the reader to the conclusion that the described product or service is the favourable SOLUTION for his or her specific problem.
