Stellar

Unmanned Department AI · Safeen Subsea

What Stellar is

Stellar is the Unmanned Department's self-hosted AI assistant. It runs entirely on the department's own server (ACS); questions and documents do not leave it, apart from Stellar reading live vessel data from NOKHADA.

It answers from the Safeen Green manuals, sea-trial and class documents, the COLREGs, and live data from NOKHADA, Watchkeeper, the RCW daily reports and the telemetry monitoring. It is an assistant: always check safety-critical answers against the source it names.

Built on open source

Stellar is built on Odysseus, an open-source, self-hosted AI workspace (github.com/odysseus-dev/odysseus), customised for Safeen Subsea by the Unmanned Department: the Stellar name and design, vessel-data connections, document library and operating instructions.
