SEAVAULT / AI data logger

Every second, on record.

SEAVAULT records every onboard channel (NMEA, Modbus, analog sensors and IP video) into one tamper-evident, time-synchronised record. Then it reads that record so you do not have to.

Capture

Every signal, on one clock.

NMEA 0183 and 2000, Modbus, analog sensors and IP cameras all land in a single time-synchronised record, sealed the moment they are written.

A record this complete is only worth what it can tell you.

Monitor

Spot the drift before it becomes a fault.

AI learns each machine's normal, then watches thermal, vibration and load against it. Every asset on board keeps a live health score.

Predict

Service it before it stops you.

Trend projection turns today's readings into a time-to-service for every asset, so maintenance fits the port call instead of interrupting the passage.
