Very quickly, the event was portrayed as a potentially serious case of foreign interference, or even as a scenario involving remote control of a vessel. The reality, as it gradually emerges from publicly available information, is more nuanced — and probably more instructive.

In this article, I explain in more detail what a maritime information system is, attempting to classify them as clearly as possible.

Maritime information systems can refer to different types of infrastructure:

• ships:
  • merchant vessels
  • warships
  • recreational vessels
  • fishing vessels
  • scientific / hydro-oceanographic / fisheries research vessels
  • barges
• ports and naval infrastructures:
  • container loading/unloading systems, smartports, logistics systems
  • Port and Cargo Community Systems
  • cranes and gantries
  • dock and basin management systems
  • locks
  • pipelines
• other onshore facilities:
  • maritime informatics of signal stations, MRCC (Maritime Rescue Coordination Centers), ship command and management centers
• offshore installations:
  • drilling platforms
  • Marine Renewable Energies (MRE): wind turbines, tidal turbines…

Next, to make things easier to understand, I tend to divide systems into two major families: “IT” systems (Information Technology), which are fairly similar to what can be found in other sectors, and “OT” systems (Operational Technology), which, to simplify, could be described as “operational systems”, more specific to the maritime information domain.
