Applications
Defence and security
The current worldwide security situation brings the governments to increase the surveillance of critical infrastructures, both above and under the water. Technological innovations related to robotics are largely supported by states, which are also the first end-users. The rapidly emerging market of aerial, ground and underwater drones has brought new tools to defence bodies, enhancing their day-to-day missions. Subsea Tech became a compelling interlocutor for civil security and defence stakeholders, providing them with ultra-portable and user-friendly underwater inspection solutions. underwater inspection solutions. Subsea Tech’s USVs (Unmanned Surface Vehicle) and mini-ROVs (Remotely Operated Vehicle) are used every day by the authorities of various countries in order to improve their homeland security at harbour and marine area level.
Surveillance of critical infrastructures
Harbour areas often include sensitive areas and facilities such as oil and gas terminals. Subsea Tech offers a full range of compact underwater surveillance solutions to help the competent authorities addressing security issues with the highest reactivity.
Missions
- Detection of intrusion by divers, submarines, etc. by visual and acoustic methods mounted in a fixed or mobile station (boom, mini-ROV or USV).
- Image processing for automatic target identification and alarm activation.
- Continuous bottom surveillance for mines, charges and other explosive devices: Use of USV for automatic target detection by imaging sonar, multibeam echosounder or sidescan sonar and visual confirmation by mini-ROV deployed from the USV.
- Inspection of ship hulls for explosive charges by USV and mini-ROV.
Benefits
- Single operator
- Combination of visual and acoustic inspection
- Wide inspection radius thanks to ROV deployment from a USV
- Ultra-portability, quick commissionning
- Access to areas difficult to reach with classic vessels

Supervision and support for divers on mission
Whether they are involved in special operations, rescue, surveillance or training, divers are most of the time supervised by a team on the surface. Subsea Tech provides the tools to optimise the missions of divers and their supervisors and their interactions.
Missions
- Mission monitoring and recording with underwater video camera system mounted on diver hat.
- Diver position acoustic monitoring (USBL)
- Diver training monitoring and recording with underwater video camera system or mini-ROV.
- Mission planning : mission mapping on diver computer, area reconnaissance with mini-ROV or USV prior to diver mission.
- Support to diver missions : acoustic positioning, sonar image display for navigation in low visibility conditions, speed monitoring, mission mapping.
Benefits
- Diver safety
- Real time video display on surface console
- Mission recording
- Lightweight and compact monitoring and support systems
- Educational tools for training

Searching for bodies or objects
Port authorities, police or civil security (firemen, sea rescuers, etc.) are regularly called upon to search for objects or bodies in variable visibility conditions. Subsea Tech assists them in their daily work by providing fully robotic and rapidly deployable solutions to optimise and secure their missions.
Missions
- Search and location of bodies in inland, harbor and coastal waters by cameras and sonars deployed by USV and mini-ROV, prior to the intervention of divers.
- Search and recovery of objects/evidence by mini-ROV or diver equipped with diving computer in the framework of investigations.
- Identification of vehicles (plate reading, identification number) by camera on mini-ROV
Benefits
- Improved research efficiency, especially in turbid waters
- Reduction of human risks related to search operations
- Reduction of personnel mobilized for research
- Reduction of research costs
- Portability of solutions from one area to another

Ship hulls inspection
Inspection of ship hulls Harbours are entry points to the national territory and must therefore be subject to increased surveillance by customs and national security authorities. Vessels are regularly used for various illegal trades, especially the underwater parts which are more difficult to control. Subsea Tech equips the competent authorities with underwater inspection systems to check the hulls of vessels on a spot or systematic basis, in all visibility conditions.
Missions
- Detection of explosive devices fixed on ship hulls using sonars and video cameras mounted on pole, mini-ROV and/or USV.
- Drug search on ship hulls using sonars and video cameras mounted on pole, mini-ROV and/or USV.
Benefits
- Improved research efficiency, especially in turbid waters
- Reduction of human risks related to search operations
- Reduction of personnel mobilized for research
- Reduction of research costs
- Portability of solutions from one area to another

Search and rescue operations
Search and rescue operations are generally carried out by national and federal authorities, through various operational bodies : Coast Guards, etc. National and local organizations often back-up state authorities in their missions. Subsea Tech’s mini-ROV are the ultimate tools to support all these stakeholders in their day-to-day operations, They allow quick and reliable assessment of the situation before the intervention of rescue teams, thus improving mission efficiency and safety.
Missions
- Body search and localization during rescue missions at sea, using underwater video cameras and sonars mounted on mini-ROV and/or USV, prior to diver intervention.
- Support to mission planning thanks to preliminary ROV and sonar image analysis.
- Supervision of diver intervention using mini-ROV or underwater video camera system.
- Support to diver missions : acoustic positioning, sonar image display on diver computer to improve navigation in low visibility conditions.
Benefits
- Rapid assessment of the situation
- Improved efficiency and safety of rescue operations
- Better planning of operations
- Portability of solutions from one area to another

Surveillance of swimming areas
Subsea Tech innovates to increase people safety in swimming areas, by implementing underwater and surface solutions to prevent risks such as drowning, shark attacks or malicious intrusions. Permanent visual and sonar surveillance using USVs allows automated coverage of the whole swimming area and provides the lifeguards and authorities with reliable and accurate information to optimize their operations. Installation of fix imaging sonars combined to image processing software allows automatic detection of intrusions and alarm triggering.
Missions
- Automatic detection of dangerous species intrusion (sharks) by imaging sonar or smart net
- Drowning situation detection by video cameras and imaging sonar mounted on USV
- Lifeguard operation monitoring with mini-ROV and USV
Benefits
- Lifeguards’ work optimization
- Reduction of costs related to beach surveillance
- Permanent monitoring allowing a great reactivity in front of a dangerous situation
- Rapid deployment to the area to assess the situation
- Continuous data recording
