ONS 2026: New Kongsberg sonar system targets offshore security and subsea threat detection

Designed for offshore security, safety and navigation applications, Kongsberg's new Aegir SSA sonar systems can be deployed on buoys, uncrewed surface vessels and fixed installations to provide continuous subsea situational awareness.

Why this news matters:

  • Growing concerns over the security of subsea pipelines, cables and offshore energy infrastructure are driving demand for technologies that can detect and monitor underwater activity in real time.

  • Kongsberg's combination of sonar sensing and AI-assisted monitoring reflects a broader industry trend toward autonomous surveillance systems that reduce operator workload while improving situational awareness.

 

At ONS this week, Kongsberg has released the Aegir SSA (Subsea Situational Awareness) family of sonars, designed to help operators detect, classify and track activity around critical offshore infrastructure, ports and coastal assets.

The systems support maritime security, safety and navigation applications and can be integrated with uncrewed surface vessels (USVs), buoys, fixed installations and larger maritime platforms.

AI-enabled sonar monitoring for offshore assets

As part of the concept, Kongsberg is offering its AI-based virtual sonar service that is designed to allow operation without continuous human oversight. The AI can be configured according to the mission requirements and trained by the client’s operators.

With ports, harbors and coastal environments, the combination of high volumes of traffic, shallow water, drifting objects and potential unauthorized activity all present risks that may be hidden from conventional monitoring systems.

The Aegir range is designed to facilitate detection, classification and tracking of objects and activities beneath the surface, while also supporting safer navigation.

Kongsberg’s booth at ONS is displaying a live data feed from an Aegir SSA sonar installation operating in the Oslofjord. The system is integrated on a Fugro's SEAWATCH buoy platform connected to the Oslofjord Testbed, providing continuous offshore monitoring, real-time data and subsea sensing.


Kongsberg is exhibiting at booth 7430 at the Offshore Northern Seas (ONS) event this week in Stavanger, Norway.
