ROV, USV and Aerial Drone Inspection
Tailored inspection services
Subsea Tech is one of the few ROV and USV inspection providers able to inspect an entire structure (water surface, submerged section and above-water section) in a single mobilization.
Our ROVs and USV catamarans are designed and built in-house. This gives us a level of responsiveness, reliability and data consistency that providers using third-party equipment cannot match.
Our CATS-certified drone pilots also carry out aerial inspections of your structures.
Since 2010, we operate in France and worldwide. 180+ missions completed. 80+ public and private clients.
Our ROV and USV inspection areas
Our teams work in every environment, from the submerged base to the above-water sections of structures, in both freshwater and marine settings.
Dam faces, water intakes, bottom outlets, gates and canals: we inspect structures both underwater and in the dry, and locate every defect.
Sea outfalls, hydraulic tunnels, drinking water pipes: video and acoustic inspection from DN 25, over lengths of up to 5,000 m.
Reservoirs, canals, ports and lakes: our uncrewed surface vessels survey the bed with a multibeam echosounder. We deliver bathymetric maps and siltation levels.
Quays, pontoons, locks and ship hulls: video and acoustic inspection, 3D photogrammetry models and siltation measurement in harbor basins.
Floating wind turbines, dynamic cables, pipelines and mooring lines: inspection, cleaning and cathodic protection measurements on offshore installations.
Posidonia seagrass meadows, reefs, seabeds and lakebeds: video, sonar and photogrammetry surveys to track how habitats change from one campaign to the next.
With the AspiROV, we inspect and clean tanks without draining them or sending in divers. It operates in drinking water, fire water, industrial water and demineralized water tanks.
Technical and human resources
The ROVs and USVs we deploy are designed and built by Subsea Tech. Because we control the whole chain, from R&D to field operations, we deliver consistent data and adapt to each site in a way that providers using third-party equipment cannot.
