How 900lbs Built a Real-Time Safety Command Center for Royal Caribbean with Photon

Photon Engine details how 900lbs built a Unity-based Safety Command Center Interactive Touch Table for Royal Caribbean Group, now deployed on 10 Royal Caribbean and Celebrity ships worldwide. The bridge-mounted system gives safety teams a shared, multi-user touchscreen view of deck plans, overlays, incident data, and checklists.

For developers, the interesting part is the architecture: Photon Realtime connects the bridge PC with tablets and other PCs so drawings, vantage points, overlays, and checklist changes propagate instantly. That makes the app less like a kiosk and more like a live collaboration tool, with synchronized state across multiple devices during an incident.

900lbs also used Photon to move from cloud-enabled services to a local deployment model without a major rewrite, which is a useful reminder that real-time middleware can shape long-term maintainability as much as initial feature delivery. The team says starting with Photon helped it iterate quickly and settle on the right implementation path.

The broader takeaway is that multiplayer tech has clear uses outside games, especially in safety-critical workflows where everyone needs the same live information. For Unity teams building multi-user tools, the story is a practical example of state sync, shared annotations, and device coordination at ship scale.
