SEAVAULT by SEALINK

Every second, on record.

The AI data logger that records every onboard channel and turns the record into decisions.

Every channel, on one clock.

Navigation buses, engine controllers, switchboards, analog gauges and IP cameras all feed one recorder. Every sample is stamped to the same time base, so a pressure spike and the camera view of that moment line up exactly.

One time base
Every channel is synchronised to GNSS time, from NMEA sentences to video frames.
Read-only by design
SEAVAULT listens to buses and sensors. It never writes to ship systems.
Works offline
Records at full resolution onboard and syncs to shore whenever a link is available.

A record you can stand behind.

Every block is hash-chained and sealed the moment it is written. Change or remove a single value and the chain breaks, showing exactly where. The integrity score tells you, at a glance, how far the record can be trusted.

Sealed on write
Blocks are chained as they are recorded, not after the fact.
Gaps and drift flagged
Missing data and clock drift lower the score and are logged with a reason.
Verifiable by anyone
Export a sealed bundle that auditors and insurers can check without access to the vessel.

Spot the problem before the alarm does.

AI learns what normal looks like for each machine, then watches for drift: a bearing running hot, a vibration signature changing, a pump working harder than it should. Every asset carries a live health score.

Detections join the record.

SEAVAULT AI recognises vessels, people and equipment states in every camera view and stamps each detection onto the timeline, next to the numbers.

Replay the voyage, second by second.

Scrub to any moment and see every channel on one timeline: engine load, position, alarms and camera views together. Settle what happened in minutes, with evidence that holds up.

Event pins
Alarms, course changes and detections are marked, so you can jump straight to them.
Video in step
Camera views follow the playhead, frame-accurate to the data.
Sealed export
Cut any window into a verified clip for the incident file.

Know when to service, before it is forced.

SEAVAULT projects each asset’s trend forward and shows when it will cross its limit. Maintenance moves from fixed intervals to the right day, with the evidence to back the plan.

Time to service
A date for every asset, with the likely range around it.
Against its own baseline
Trends are read per machine, not against a generic limit.
Planned around ports
Service windows follow the voyage plan, so work lands in port rather than at sea.
