Teledyne Marine participated in the 2026 edition of the SeaSEC Challenge Weeks, “DATA2SEA,” an advanced maritime security exercise focused on real-time multi-sensor data integration for the protection of critical underwater infrastructure (CUI).
Hosted by the Rostock Institute for Ocean Technologies in collaboration with the German Navy, the exercise was conducted in the Baltic Sea within the Mecklenburg Bight, including the Digital Ocean Lab and the Rostock naval base. The program brought together a range of sensing technologies in realistic operational conditions, shifting the focus from individual system performance to the integration of multiple data streams, reflecting a growing priority for maritime security operators.
Teledyne Marine and Teledyne FLIR contributed integrated above- and below-surface surveillance capabilities across cable, platform, and harbour protection scenarios. Teledyne’s role as a sensor provider within multiple consortiums also demonstrated how coordinated sensing approaches with partner organisations can enhance monitoring and protection of CUI.
Morten Bernsdorf, Project Lead at Teledyne Marine, commented, “Protecting critical underwater infrastructure increasingly depends on the ability to connect and interpret data across multiple domains. SCWD2S provides a valuable platform to demonstrate how integrated sensing can enhance maritime situational awareness at scale, while bringing together industry partners to collaboratively address shared challenges and showcase what Teledyne’s technology is capable of in real-world conditions.”
In the Platform Protection challenge, participants were required to locate, identify, track, and report threats to an offshore platform and its restricted zone. In the Nienhagen area, two Teledyne Marine passive acoustic monitoring (PAM) nodes provided continuous underwater surveillance and early detection of potential intrusions. Upon detection, a seabed-mounted SeaBat F50 forward-looking sonar was activated to visually investigate activity.
In collaboration with Stormborn, an unmanned surface vessel (USV) equipped with a PAM node, as well as SeaBat F50 and SeaBat T51 multibeam imaging sonars, enabled mobile detection and scanning of intruders or underwater objects across the seabed and water column. A shore-based Teledyne FLIR thermal imaging camera completed the multi-domain picture by monitoring surface activity.
The Harbour Protection challenge required the detection of all traffic and the reporting of any intruders crossing the harbour entrance. At Sportschule Warnemünde harbour, Teledyne deployed a multi-layered surveillance solution as part of Consortium C. A PAM system installed on the seabed detected underwater intrusions such as divers and unauthorised AUVs and ROVs.
Instead of transmitting data in real time, the team provided bearings indicating unusual underwater acoustic activity. These were then correlated via a C2 system with radar or AIS tracks to determine whether contacts were known or potential threats. Real-time visualisation was provided by the SeaBat F50 sonar, while a Teledyne FLIR infrared camera delivered wide-area surface monitoring from land.
Founded in December 2023, the SeaSEC initiative brings together technology providers, infrastructure operators, public authorities, industry, and research partners to collaborate in realistic maritime test environments. Through its participation in the DATA2SEA exercise, held from April 13 to 24, Teledyne demonstrated how integrated sensing technologies can deliver actionable intelligence for effective CUI protection, while contributing to collective learning across the maritime security community and supporting the development of next-generation subsea security solutions.
