The "Stone Ship": Real Applications for Industry and Research
The Bridge Laboratory at Fraunhofer CML combines two elements in one: the antenna system and the classified bridge system, which technically transform the research building into a real seagoing vessel—the stone ship in the middle of Harburg’s inland port. What advantages does this offer partners and customers? What role does cybersecurity play in this context? Jan Solle explains this as he gives you a tour of his laboratory in the video.
Overview
The Fraunhofer CML bridge laboratory replicates a real ship’s bridge with certified equipment—connected to an antenna system that provides real-time navigation and radio data. Instead of using simulations, we work with real data and real hardware. This allows us to test devices, network topologies, and entire bridge systems for cybersecurity risk-free—without endangering an actual ship.
Background
The increasing interconnection of IT and OT systems on board, outdated software due to long ship lifespans, and growing regulatory requirements make cybersecurity testing indispensable today.

| Flexibility | Expandable to include new devices; customizable network topologies |
| Attack Simulation | Software tools for automated, user-friendly execution of cyberattacks |
| Assessment | Structured methodology for maritime cyber risk assessment |
| Response | Development of response and recovery plans; role definitions |
| Training | Practical training for seafarers on how to handle cyberattacks |
MaCy Project – Maritime Cybersecurity
As part of the MaCy project, we are researching how cyberattacks on ship bridges can be detected early and effectively defended against. We are placing particular emphasis on:
- Clear presentation of incidents – rather than simply issuing yet another alarm signal, we develop clear recommendations for the crew on how to respond.
- Practical training – since studies show that four out of five seafarers feel inadequately trained in the use of digital technologies, we train response skills in a realistic environment.
- Detection using real-time data – improving attack detection through direct data access via the antenna system.
Benefits for Industry Clients and Research Partners
- Risk-free testing: Hardware and software can be “safely” attacked without compromising your own data or systems.
- Realistic results: Thanks to real components and real-time data, findings are directly applicable to actual ships.
- Customization: Partners can bring in their own devices and network topologies for testing.
- Regulatory compliance: Support in meeting national and international cybersecurity regulations.
- Holistic approach: From technical testing to staff training—everything from a single source.

FAQ
Does the lab actually work with real data? Yes. Through the antenna platform, the bridge receives real-time navigation and radio data around the clock—this is not a simulation.
Is there a risk to our own systems or data? No. All tests take place in an isolated environment within the lab, so your systems are not at risk.
Can we bring in our own devices to have them tested? Yes, the bridge lab can be flexibly expanded to include additional devices and adapted to individual network topologies.
Is this service only for shipping companies? No, device and software manufacturers can also have their products tested for cybersecurity in the lab.
Does the laboratory also offer training for crews? Yes, as part of the MaCy program, realistic attack scenarios are conducted and tested to train seafarers.
