MetroSea
Survey and metrology tools for offshore and maritime operations
Survey and Metrology for the Field
MetroSea helps teams collect, check, visualise, and report measurement data during real operations. It is a complete survey and metrology system that can include software, calibrated sensors, positioning equipment, field enclosures, RTK infrastructure, integration, and commissioning.
- Real-time multi-sensor data acquisition and fusion
- Offshore positioning, alignment, and deformation monitoring
- Automated quality checks, tolerance monitoring, and reporting
- Support for GNSS, laser trackers, total stations, IMUs, and acoustic systems
Survey and Metrology Services
MetroSea delivers across seven core service areas, each integrated into our software platform.
Dimensional Control Survey
As-built surveys and dimensional control for offshore structures. Covers FPSO loadout and mooring alignments, pipeline and riser geometry, jacket and topside mating, and quayside checks before offshore campaigns.
Offshore Positioning Survey
Vessel-installed positioning systems using GNSS, laser trackers, and total stations integrated with motion reference units for real-time 6-DOF positioning and alignment data.
Real-Time Structural Monitoring
Continuous structural deformation and motion monitoring using distributed strain gauge, accelerometer, and IMU arrays. Live dashboards with configurable alerts and automated reporting.
Subsea Measurement
Acoustic positioning for subsea operations including USBL, SBL, and LBL configurations. Integrated with surface GPS for accurate subsea asset tracking and survey.
Environmental Monitoring
Metocean monitoring using GNSS-referenced meteo buoys, multibeam bathymetry, current profiling, and wave measurement for real-time operational decision support.
Offshore RTK Base Station Deployment
Deployment and operation of offshore RTK base stations and supporting GNSS infrastructure for reliable positioning, alignment, and survey reference during campaigns.
USV-Based Survey
Uncrewed surface vehicle survey operations for restricted or hazardous areas. AUV and USV platforms integrated with MetroSea software for autonomous data acquisition.
Data Management and Reporting
End-to-end data processing, quality control, and reporting. Survey reports, measurement certificates, CAD exports, and digital deliverables tailored to project requirements.
