ClamVision calculates dredged volumes continuously throughout the project, giving project managers up-to-date production figures without waiting for a post-dredge survey.
How volume is calculated
ClamVision generates triangulated surfaces (Delaunay triangulation) from bite positions, sonar soundings, and imported survey data. Volume removed is computed as the difference between the pre-dredge (design or original survey) surface and the current work surface. Calculations are updated automatically as each bite is recorded.
- Cut and fill analysis — areas where material has been removed are shown separately from areas where material remains or has been over-dredged
- Cross-section area reporting — any survey line through the project can be extracted as a cross-section with area calculations at user-defined station intervals
- Phase tracking — multi-phase projects can track volume independently per phase or contract reach
- Real-time production metrics — daily totals, shift totals, and running project totals are displayed continuously without any manual calculation
Production reports
ClamVision generates production reports automatically on a schedule or on demand:
- Volume removed by date, shift, or project phase
- Bite count, average depth achieved, and depth variance
- Grade compliance percentage — how much of the area meets the design depth tolerance
- Equipment utilization and idle time
- Downloadable as PDF, CSV, or DXF for submission to clients and regulators
Why accurate volume matters
Volume is money in dredging. Inaccurate production figures lead to disputes with clients, under-billing for actual work performed, and uncertainty about project completion timelines. ClamVision’s continuous surface-differencing approach means your production numbers are grounded in sensor data rather than approximations, and discrepancies between pay quantities and field measurements shrink dramatically.
