See every bite. Hit every grade.
ClamVision turns your dredge's sensors into a live 3D picture of the dig: bucket position, design surface, tide, and production, so your crew stops guessing and starts proving.
Built for the bucket, not adapted to it
ClamVision was built from the ground up for clamshell and excavator dredging by the hydrographic surveyors at Sea Sight Survey, people who measure dredge projects for a living.
- Guidance
Dig with certainty
A live 3D model of your barge, boom, and bucket, driven by GPS, encoders, and inclinometers, shows the operator exactly where the bucket sits against design grade, corrected for tide, on every single bite.
- Production
Prove your volume
Continuous surface differencing turns every recorded bite and sonar sounding into defensible volume numbers. Daily, shift, and project totals update themselves, with no waiting on a post-dredge survey to know where you stand.
- Operations
Run the whole spread
Relay Server and DredgeHQ cloud integration connect every dredge, survey boat, and office screen to one shared project. Push a new design surface from shore and every vessel has it in seconds.
Your whole project on one screen
Georeferenced satellite imagery, chainage stations, design lines, the live barge and swing arc, and every recorded bite color-coded by depth. This is what your operator, superintendent, and client all see, updating together in real time.
- Bite heatmap. Under-dredged areas stand out immediately.
- Live equipment model. Barge, boom, and bucket move in sync with the machine.
- Real-time cross-sections. A live profile slice through the current dig position.

From pre-dredge survey to final acceptance
How a project runs in ClamVision.
Import the pre-dredge survey
Load soundings and surfaces from LandXML, DXF, XYZ, Shapefile, or native multibeam formats (KMall, S7K) to establish the existing bottom. No external CAD or GIS software required.
Load the design surface
Import the required finished grade and tolerance. ClamVision renders it as a colored mesh in every view, in your project's coordinate system: UTM, local grid, or custom projection.
Calibrate the spread
A structured workflow walks you through antenna offsets, boom geometry, and inclinometer alignment, then verifies the result against a known survey point. Test the whole setup in the office first with the built-in sensor simulator.
Dredge with live guidance
Every bite is recorded with position, depth, tide, and GPS quality. The work surface updates itself, volumes accumulate in real time, and under-dredged spots are flagged before the barge moves on.
Verify and report
Import the post-dredge survey, run cut/fill comparisons, and hand the client grade-compliance and production reports as PDF, CSV, or DXF, generated automatically and grounded in sensor data.
Everything the dig demands
Fourteen integrated capabilities, one project file. No modules to stitch together, no data to shuttle between programs.
- Real-Time 3D Visualization A live, sensor-driven 3D model of the barge, boom, bucket, and bottom, what the operator sees is what the machine is doing.
- Clamshell Dredge Guidance Built from the ground up for clamshell dredging, every bite logged automatically with position, depth, tide, and GPS quality.
- Excavator Dredge Guidance Full articulated-arm modeling, boom, stick, and bucket angles fused with GPS and inclinometers for a live bucket-tip position.
- GPS Positioning & RTK Multi-channel GPS across the whole spread, built-in NTRIP RTK corrections, and a full offset model down to the bucket tip.
- Pipeline & Trench Dredging Chainage-based progress tracking along the pipeline alignment, with live cross-track offset and trench-grade profiles.
- Hydrographic Survey Integration Import surveys from LandXML, DXF, XYZ, Shapefile, KMall, and S7K, and run the whole pre/post-dredge workflow without external CAD or GIS.
- Sonar & Bottom Mapping Live multibeam point clouds rendered right beside your equipment and design surface, see depth conformance in context.
- Tidal Compensation Live tide gauges and NOAA water levels correct every depth to project datum, the operator never mentally adjusts for the tide again.
- Calibration & Setup Tools A structured calibration workflow with graphical verification, plus a sensor simulator to prove the setup before you mobilize.
- Volume & Production Tracking Continuous surface differencing turns every bite into up-to-date, defensible volume numbers, no waiting for the post-dredge survey.
- Reporting & Data Export The documentation that contractors, clients, and regulators require, generated automatically as PDF, CSV, DXF, Shapefile, or KML.
- Fleet & Multi-Vessel Relay Server networking and DredgeHQ cloud monitoring connect every dredge, survey boat, and office screen to one shared project.
- Mobile Monitoring App A native Android app running the same core engine as the desktop, live plan view, 3D visualization, and project management on a tablet.
- Sensor Integration Platform Pre-built drivers for 90+ devices, GPS, INS, encoders, sonar, tide gauges, plus CAN bus, OPC UA, MQTT, and serial protocols.
Know the bottom like you can see it
Multibeam and single-beam sonar, color-scaled depth surfaces, and live cross-sections put the invisible part of the job, the part you're paid for, right in front of the crew.

Software from surveyors, not just software people
ClamVision is built by Sea Sight Survey, hydrographic surveyors with 50+ years of combined experience measuring marine construction from the Great Lakes to the Gulf. The people who write the code are the people who stand behind the survey data.
- USACE-compliant DQM experience across federal dredging work
- Coast-to-coast support across the Great Lakes, East Coast, West Coast, and Gulf of Mexico
- Training and commissioning on your vessel, with your crew, on your project
- Survey-grade standards. Dependable, defensible results are the product
