Rapid Underwater Assessment
INDUS can be deployed to examine water depth, underwater terrain, submerged obstacles, structural conditions and potential access routes before personnel enter the water.
INDUS ROV · Key Application
INDUS Underwater ROV for Search, Rescue and Recovery
Real-time underwater visual intelligence for rescue teams - before and during diver deployment.
Overview
Underwater Search, Rescue and Recovery with INDUS ROV
INDUS ROV gives rescue teams live underwater video before and during diver deployment. It searches rivers, dams, flooded buildings, quarries and coastal water, uses optional sonar where visibility is poor, and records target positions so divers and recovery teams go in with a plan.
Underwater emergencies are sudden, time-critical and technically demanding. Poor visibility, strong currents, submerged structures, uncertain depth and hazardous debris can delay search operations and expose divers to significant risk.
The INDUS Underwater ROV, developed by Benzz Technologies Private Limited, provides rescue teams with real-time underwater visual intelligence before and during diver deployment. Operated remotely from the surface, INDUS can investigate submerged terrain, locate missing persons or objects, inspect confined and hazardous areas, and support safer rescue and recovery planning.
Deployment
Designed for Indian Rescue Environments
INDUS can support emergency-response operations across a wide range of inland and coastal environments.
- Rivers, lakes, ponds and reservoirs
- Dams, canals and irrigation structures
- Flooded roads, buildings and industrial facilities
- Water-filled mines, quarries and tunnels
- Open wells, bridge foundations and culverts
- Ports, harbours and coastal waters
- Ship, boat and vehicle accidents
- Cyclone and flood-affected areas
Capabilities
How INDUS Supports Emergency Rescue
Search and Target Identification
The onboard 12 MP 4K UHD camera, high-intensity underwater lighting and optional imaging sonar help operators search for missing persons, submerged vehicles, boats, equipment and other targets. Sonar can assist detection where mud, silt or low visibility limits conventional cameras.
Real-Time Situational Awareness
Live video, sonar and sensor information can be transmitted to the surface control station, allowing rescue commanders, divers and technical specialists to evaluate underwater conditions and coordinate the response.
Underwater Positioning
Optional USBL positioning and surface GNSS integration can help record the approximate location of identified targets, underwater hazards and inspected areas. This supports systematic search coverage and reduces unnecessary repeat searches.
Confined and Hazardous-Area Inspection
The compact ROV can investigate areas that may be unsafe or difficult for divers, including culverts, bridge gates, submerged buildings, flooded shafts and debris-filled structures.
Recovery Assistance
An optional robotic gripper or recovery attachment can be used to examine, secure or assist with retrieving suitable small objects. For major recovery operations, INDUS provides target information to help teams select the appropriate lifting and salvage equipment.
Operational Value
Key Operational Benefits
Improved responder safety
Reduces unnecessary diver exposure during initial assessment.
Faster deployment
Enables rapid preliminary investigation from the shore, boat or rescue platform.
Extended search coverage
Supports systematic underwater searches beyond normal diver endurance.
Low-visibility capability
Combines lighting, 4K imaging and optional sonar for turbid water.
Accurate documentation
Records video, images, observations and target-location information.
Reduced search time
Helps teams concentrate personnel and equipment in priority areas.
Multi-agency coordination
Live information can support NDRF, SDRF, Fire and Rescue Services, Police, Coast Guard and authorised disaster-management teams.
Modular configuration
Cameras, sonar, positioning, environmental sensors and recovery tools can be selected according to the incident.
Use Cases
Typical Emergency Applications
- Search for missing or drowned persons
- Submerged vehicle and vessel location
- Flooded mine, tunnel and quarry inspection
- Bridge, dam, sluice-gate and culvert emergencies
- Underwater accident investigation
- Hazardous-object reconnaissance
- Evidence and valuables recovery support
- Post-flood structural assessment
- Coastal and harbour rescue support
- Underwater route and access-point inspection
Method
Typical Rescue Workflow
- Define the last-known location and priority search area.
- Assess surface conditions, water flow and deployment hazards.
- Deploy INDUS from the shore, rescue boat or suitable platform.
- Conduct a planned visual and sonar search pattern.
- Identify and record targets, obstacles and access routes.
- Mark relevant locations using available positioning information.
- Share real-time findings with the rescue commander.
- Plan diver entry, recovery or lifting operations using the collected data.
Operational note: INDUS is a decision-support and remote-inspection system. It does not replace trained rescue divers, incident-command procedures or statutory rescue protocols. Deployment should be conducted by trained operators under the responsible rescue authority.
