Digital Onboard Visit on the Calisto: Where AI Meets Maritime Technology

On April 8, 2025, the time had come: As part of the AI-Healthy Ship project, Dr. Lukas Belz from the ZfAM project team and the development team from Lionizers visited the Calisto, a container ship operated by Peter Döhle Schiffahrts-KG, docked in the Port of Hamburg. The aim was a technical short visit to assess the ship’s existing server landscape and IT infrastructure, as well as its compatibility with the planned system — laying a crucial foundation for the future deployment of digital health and assistance systems onboard.

The key questions: What equipment is currently available? How are data flows managed? And what prerequisites must be met to bring sensors, software, and AI models safely and efficiently onboard?

One central finding: Space for additional hardware is limited. Tobias Neben, project lead at Lionizers, summed it up clearly:

“Space is tight — we need to work with the existing infrastructure and design modular solutions wherever possible.”

Connecting Sensors to the Onboard Server
Precision meets practice: Tobias and a colleague analyze the live data from onboard sensors. With every connection, the AI system becomes smarter — soon delivering personalized health recommendations directly to crew members' devices. .
Expertise from ZfAM and Lionizers in the Server Room
Lukas from ZfAM and the Lionizers team perform a final system check in the server room. With sharp focus and technical know-how, they ensure the digital health network onboard runs reliably and is ready for daily use by the crew.
