Critical Underwater​ Infrastructure​​

Protecting the Unseen: Beneath the ocean’s surface lies the foundation of global security - subsea cables, offshore energy systems, and strategic maritime assets. 

As threats to this Critical Underwater Infrastructure grow, so does the need for advanced protection.

Our solutions are flexible and scalable: deployed as fixed installations on the seabed or harbor walls, mounted on unmanned v​ehicles​, or carried by surface platforms. This modular approach ensures the right level of coverage, whether the need is persistent surveillance, rapid inspection, or wide-area monitoring.
​​

• Passive acoustic monitoring: Arrays of Teledyne hydrophones​ detect and localize abnormal underwater sounds - such as diver activity, underwater drones, or mechanical interference with exceptio​​nal precision. Apex floats​ provide persistent, autonomous monitoring, ideal for stealthy deployments, and provide baseline environmental data that enhances detection of underwater threats.
  
  
• Active acoustic monitoring: Forward-looking sonars​ such as the SeaBat 7123 MkII​ provide long-range threat detection at stand-off distances, while compact systems like the SeaBat F50​ deliver high-resolution imagery for close inspection. 
  
  
• Autonomous surveillance: Vehicles including the Osprey​ and SeaRaptor AUVs​ and the Sentinel Glider​ extend monitoring to remote and deep-water areas, carrying modular sensor payloads for inspection, mapping, and detection tasks.

By combining these technologies, Teledyne Marine enables naval and security forces to reduce risk, deter hostile activity, and safeguard critical underwater infrastructure with reliable, field-proven solution​
