SUBSEA CABLE PROTECTIOn

Our lives today are dependent on critical undersea infrastructure: subsea telecoms cables, power cables and offshore oil and gas pipelines. They carry 99% of international data, trillions of dollars in financial transactions and a large proportion of many countries’ energy supplies. Yet these critical assets are occasionally exposed to external damage and targeted by malicious actors. To reduce the likelihood of costly disruption or even a catastrophic outage, we offer a complete subsea cable protection and security service: 24/7 monitoring, proactive interventions and suspicious vessel tracking.

GET PEaCE OF MIND WITH OUR COMPLETE SUBSEA cable SECURITY SERVICE 

Protecting something so crucial to our way of life (and your business), requires more than just the latest technology. It requires a human touch. Our experienced mariners and intelligence analysts actively monitor every vessel, interpret risks, and intervene when it matters most. They understand what the data is showing and know how to communicate with mariners at sea. Of course, we still use the latest technology, best-in-class data, with the quickest response time. Our mariners just know what to do with it, giving you complete peace of mind.

How We PROTECT SUBSEA INFRASTRUCTURE 

Ambrey combines real-time maritime intelligence, vessel tracking, and operational expertise to help protect subsea infrastructure and reduce the risk of costly disruption. 

Subsea cable protection through real-time monitoring and vessel tracking of underwater infrastructure

Prepare

Our team of Intelligence Analysts and Maritime Operations Officers work 24/7 to track vessel activity and identify potential threats. 

Support

When a security threat is identified, we alert our members, contact the vessel and coordinate our response with regional authorities.  

Respond

By combining continuous active monitoring, maritime intelligence and behaviour tracking, we help infrastructure owners reduce the risk of damage. Resiliency is increased, as monitoring creates an ongoing deterrence to vessels coming back.
