Applications
Defense & Maritime Security
The evolving global security environment requires public authorities and defense organizations to strengthen the surveillance of critical infrastructure, both on land and underwater. Ports, coastal areas, and certain industrial facilities represent sensitive locations where underwater threats can be difficult to detect using traditional monitoring methods.
Advances in robotics and autonomous systems have significantly improved the capabilities of defense and security stakeholders. Aerial, ground, surface, and underwater drones now make it possible to monitor large areas, inspect submerged infrastructure, and detect potential threats more effectively.
Subsea Tech develops compact and rapidly deployable robotic solutions dedicated to maritime security operations. Surface drones (USV) and remotely operated underwater vehicles (ROV) enable authorities to perform underwater inspections, search operations, and surveillance missions in ports, coastal zones, and inland waters.
These systems help improve operational efficiency while reducing risks for personnel.
Typical Applications
Subsea Tech solutions are used by defense authorities, civil security agencies, and law enforcement for missions such as:
-
surveillance of sensitive maritime infrastructure
-
detection of underwater threats in ports and harbor areas
-
ship hull inspection
-
search operations for submerged persons or objects
-
diver supervision and assistance
-
monitoring of coastal and bathing areas
Critical Infrastructure Surveillance
Port and maritime areas often include sensitive facilities such as oil and gas terminals, naval bases, or strategic industrial sites. Monitoring underwater areas around these infrastructures is essential to detect potential threats such as divers, underwater vehicles, or suspicious objects.
Subsea Tech robotic systems enable rapid deployment of underwater inspection and surveillance tools capable of operating in confined environments or low-visibility conditions.
ROVs and USVs equipped with cameras and acoustic sensors allow operators to detect intrusions, inspect underwater infrastructure, and support security operations while limiting operator exposure to risks.
Typical missions include:
-
detection of diver or underwater vehicle intrusion using visual and acoustic methods
-
monitoring of harbor seabeds to detect suspicious objects or explosive devices
-
sonar mapping of port areas using surface drones
-
visual confirmation of targets using an inspection ROV
Search and Recovery Operations
Port authorities, police services, and civil protection organizations are regularly required to search for persons, vehicles, or objects underwater in environments where visibility is often limited.
Our solutions make it possible to conduct these search operations more safely and efficiently through the combined use of sonar systems and underwater cameras.
Surface drones can quickly scan large areas using acoustic sensors, while ROVs provide visual confirmation of detected targets and can assist divers when necessary.
Typical missions include:
-
search and localization of bodies in inland, port, or coastal waters
-
detection of submerged vehicles or objects
-
recovery of objects or evidence during investigations
-
visual inspection prior to diver intervention
These tools reduce operational risks while improving the efficiency of search operations.
Diver Supervision and Assistance
In many security or rescue missions, divers operate in complex underwater environments where visibility may be extremely limited. Providing real-time monitoring and surface support is therefore essential.
Subsea Tech solutions offer tools dedicated to diver mission supervision, underwater communication, and mission preparation.
ROVs can assist divers by inspecting an area before intervention, monitoring operations in real time, or providing navigation information in low-visibility conditions.
Typical missions include:
-
supervision of diver operations
-
reconnaissance of an area before diver deployment
-
acoustic tracking of diver positioning
-
support during rescue or recovery operations
These technologies improve diver safety and provide surface teams with better situational awareness.
