Application
Aquaculture
The total annual aquaculture production contributes to 45% of the world aquatic product consumption. Maintaining production infrastructures and equipment in proper operational conditions, securing the production and ensuring compliance with hygiene and health standards represent critical challenges regarding food security and public health aspects. Subsea Tech contributes to address these challenges by providing aquaculture farms of the main producer countries, among which Norway and Chile, with lightweight, user-friendly and affordable underwater inspection and surveillance systems for the daily operation/maintenance and cleaning tasks, as well as for the protection of production areas. La portabilité des Subsea Tech’ mini-ROV ultra-portability allows easy transportation and deployment from one site to another, thus ensuring a quick return on investment for the shareholders.
Inspection of nets, buoys and anchors
In response to the regulations and operational constraints of aquaculture operators, Subsea Tech mini-ROVs can be deployed instantly on any exploitation, with or without power source, to perform punctual or regular inspections of submerged infrastructures and equipment: nets, bungs, anchors, buoys, etc.
A permanent monitoring can also be set up by underwater cameras mounted in a fixed position and giving a real time video feedback to the surface.
Missions
- Visual inspection of nets and buoys to detect and locate anomalies
- Visual inspection of anchors to estimate the level of concretions
Benefits
- Reduced costs and risks compared to diver inspections
- Increased inspection flexibility compared to the use of diving teams

Dead fish collection
In order to comply with the Chilean legislation, which requires the daily collection of dead fish in aquaculture operations, Subsea Tech has developed an overpowered mini-ROV capable of towing a net to collect dead fish deposited on the bottom of the tanks. This mini-ROV allows a significant reduction of time, costs and risks compared to the use of traditional methods (divers).
Missions
- Collect dead fish on the bottom of the ponds
Benefits
- Reduction of costs and risks compared to the intervention of divers
- Reduction in the duration of operations
- Increased inspection flexibility compared to the use of diving teams

Detection of intrusion of dangerous species for production
In some areas of the world, aquaculture operations are regularly attacked by harmful species: sea lions, sharks, etc. Subsea Tech assists operators in the prevention of attacks and the preservation of their production, by providing them with automatic underwater intrusion detection systems using sonar or connected nets.
Missions
- Automatic detection and location of pest intrusion and triggering of an alarm
Benefits
- Permanent monitoring of access to production areas
