    Marine construction visualization systems help improve the accuracy, efficiency and speed of dredging, piling, placement and hydrographic surveying workflows.
    Innovative 3D visualization applications significantly improve the accuracy of dredging and surveying by empowering the operator to work smarter and to avoid rework.
    Marine Visualization Software Components
    Leading 3D visualization systems can support a breadth of applications and dredging and marine construction operations, including:
    • Dredging:
      • Backhoe/excavator dredger
      • Grab/clamshell dredger
      • Cutter suction dredger
      • Bucket dredger
    • Rock Dumping and Placement
      • Caisson placement
      • Block placement using a wire crane or excavator
      • Vertical and raked pile placement
    • Inspect, Repair, and Maintain (IRM)
    • Hydrographic Survey
      • Single beam hydrographic survey
      • Multi-beam hydrographic survey
    Track Work in Progress
    • Provides real-time visualization of the dredge tool showing the operator the actual versus planned surface being constructed.
    • With visualization technology the operator has a real-time view of the dredge and barge in plan and profile views.
    • For an excavator dredge, the position of the bucket relative to the design is tracked continuously and displayed.
    • A color-coded Digital Terrain Model (DTM) highlights the high and low spots compared to the design.
    • The model is updated in real-time from the position of the bucket teeth and the bucket width, which, as a result, tracks the progress of the dredging work.
    • The surface DTM is updated registering the development of the dredging work and showing depth, differential and production models according to the progress of the bucket.
    • Combined with sonar technology, dredging companies, and those focused on hydraulic engineering, construction, offshore and survey have an even greater underwater vision in the most challenging inshore underwater environments and conditions.
    Visualization Adds Verification and Improves Safety
    • Seeing what is underwater in the proximity of the work or seeing the work removes the need for intermediate inspections with ROVs or divers.
    • Removing the diver from the project will reduce the hazard for personnel working with the system.
    • A construction barge can be used for scanning an area without the need for a survey vessel. This improves productivity by removing the need for post-survey processing.
    Real-time Visualization and Reporting
    • Machine operators can set over-dredge and under-dredge tolerances on the profile view of the dredge head.
    • A 3D picture gives the operator an explicit visual representation of where they need to position the dredge head underneath the water.
    • Provides real-time sensor data gathering, computation, display and logs.
    • Also provides options to display data either graphically or alphanumerically and to present the data in the form of models, tables, files, volumes, nautical charts or reports.
    • Enhance communication with internal teams while also strengthening customer communication and trust.
    Selecting Hardware Components and Accurate Positioning Systems
    • GNSS receivers can use corrections from a site base station or VRS to achieve high accuracy.
    • Precision is maintained via precise sensors on the dredge, barge, cranes, tugs and excavators are continuously feeding the software data for accurate roll, pitch and location information.
    • Additional components include in-cab displays, surface viewing screens, GNSS receivers, pitch and roll sensors, and communications (e.g. Wi-Fi, radio or cellular).
    • Marine receivers and positioning sensors provide the ability to monitor tidal and other water level changes in real-time.
    • Our most advanced dual-frequency, real-time kinematic (RTK) receivers deliver precise dynamic positioning with 20 mm (1”) accuracies, 20 times per second with a latency of less than 20 milliseconds.
    • Receivers receive corrections from a traditional base station or other sources.
    Software, Hardware, Training and Support
    • Consistent uptime from every sensor and 3D visualization component is necessary in order to collect accurate data and to ensure enhanced production over the life of the project.
    • Opting for a more integrated implementation where they deploy marine-specific hardware and software from a single vendor eliminates the potentially costly risk of integration challenges that can cause slowdowns or missed opportunities.
    • Components are deployed from one manufacturer or partner and share a standard interface.
    • Users can reuse data and accessories across multiple applications much more efficiently and those integrations are already built to work with existing hardware and workflows.
    • Operators and training managers can spend less time training and more time getting work done, as the software similarities between workflows make it easy to transition.
    3D Onboard Displays
    • Includes an in-cab display and surface viewing screens. Gives operators a real-time overview of the excavator and barge from multiple views.
    • Accurately display and record complex design surfaces and a 3D display of the bucket as it breaks the seabed surface.
    • Guides the operator back to the last dig each time work begins.
    • Essential feature when projects take place over several weeks or when machines need to stop at designated times to keep shipping lanes clear.
    • Displays are customizable, giving lead engineers the ability to set up the screen to meet their exact preferences and to sync up with existing workflows.
    • Displays have larger screen resolutions and clearer screens that enhance the operator experience with 2D and 3D profile information, grade guidance, and warnings.
    Environmental Auditing
    • Provides easy-to-understand graphs, maps and tables to update the project manager and ensure that stakeholders are informed of any changes or work completed around sensitive environments.
    • Reporting capabilities tied directly into the visualization software and guidance technology can streamline the reporting process allowing project managers to create volume reports and other status reports.
    Return on Investment
    • By tracking ‘as-building’ progress, contractors can avoid rework and the potential to return a machine to a site after the survey when areas may have been missed or material has moved.
    • Real-time progress reports also provide an early indicator that the project will be delivered on time.
