§ 01 / Hydrographic surveys

Mapping the
seabed.

Detailed underwater mapping that shows ports, pipelines, cable routes and coastal projects exactly what's on the seabed — so engineers can plan with confidence before any work begins.

  • BathymetryMultibeam sonar acquisition and processing
  • ImagingSide-scan sonar for clear seabed pictures
  • MappingCharts and reports your engineers can use directly
  • CoastalPort, harbour and infrastructure surveys

§ 02 / Seismic surveys

Reading
the layers below.

Sound-based imaging that reveals what the seabed is made of — essential before drilling, foundation work or major construction. Knowing the layers below saves time and risk above.

  • Survey2D seismic acquisition for offshore projects
  • InterpretationIdentifying ground conditions and hazards
  • Pre-constructionFoundation and drilling-site assessment
  • ReportingClear results for engineering teams
§ 03 / Geotechnical investigations

Knowing the
ground.

Soil and seabed sampling that tells you whether the ground can hold what you plan to put on it — for foundations, anchors, cables and pipelines.

  • SamplingSeabed soil sampling and testing
  • FoundationsSuitability assessments for offshore structures
  • Cables & anchorsInvestigations for cable burial and anchor design
  • ReportsClear, decision-ready documentation

§ 04 / Data analysis

From measurement
to decision.

We acquire, analyse and process hydrographic and geospatial data — turning what we collect into the highest-accuracy seabed maps, pipeline monitoring and environmental assessments.

  • ProcessingHydrographic and geospatial data processing
  • AnalysisPipeline monitoring and structural review
  • 3D modellingClean, accurate models from raw laser scans
  • ReportingGIS-ready deliverables and reports
§ 05 / Subsea engineering

Subsea
engineering.

Our qualified team designs, installs and maintains underwater structures, pipelines and inspection systems — using ROVs, AUVs and sonar to deliver safe, efficient and innovative subsea solutions tailored to deep-sea conditions.

  • InspectionPipeline and structural inspection with HD/4K imaging
  • 3D modellingVoyis stereo photogrammetry — millimetre-accurate
  • Working depthUp to 4,000 m
  • MaintenanceInspection, repair and maintenance programs

§ 06 / Position engineering

Knowing exactly
where things are.

High-precision positioning for offshore drilling support, rig moves, anchor handling and marine construction — so every measurement and every operation is anchored to the right place.

  • DrillingDrilling support and rig positioning
  • ConstructionPipelay and structure-installation positioning
  • TrackingUSBL beacon installation and ROV tracking
  • Operations24/7 offshore positioning support
§ 07 / Remote operations

Subsea, run
from shore.

Our remote operations team is dedicated to revolutionising subsea management with innovative technology and expertise. By advancing our skills and knowledge in remote operations, we set new standards in supporting marine projects.

  • SupportReal-time support for marine projects
  • MonitoringRemote inspection and live data review
