A sealed account
of every second.

Every onboard channel recorded into one tamper-evident log on a single timebase, ready for any safety review or inquiry.

One record, every channel NMEA 0183/2000ModbusAnalog sensorsIP video

Capture, seal, decide.

Capture

Every channel on board, from navigation to machinery to video, lands on one shared timebase the moment it happens.

Seal

Each entry is hash-chained into a tamper-evident log, so the record cannot be altered later without the break showing.

Decide

Crew and investigators read the same account, second by second, long after the event itself.

Everything on board, held on one record.

NMEA 0183/2000
Position, heading, speed and depth from the bridge.
Modbus
Engines, generators and auxiliaries from the machinery space.
Analog sensors
Temperature, pressure and level across the plant.
IP video
Bridge, deck and machinery cameras, time-synced to the data.
Onboard systems sealed into one continuous SEAVAULT record

Tamper-evident by design.

Each entry is hash-chained to the one before it, so the log cannot be altered after the fact without the break showing.

What the vessel recorded is what a later review reads, down to the second, on the bridge and ashore alike.

How the record is sealed

Reconstruct any incident, exactly as it happened.

Position, machinery and video stay aligned on one timeline, so an event replays second by second, checked against what the cameras actually saw.

Operational review

Built to stand up to review.

The same record serves the crew day to day and an investigator long after the fact.

Keeps recording through blackout

An edge buffer holds the log through power loss and link loss, then closes the gap once service returns, so the window is never left empty.

One clock for every input

NMEA 0183/2000, Modbus, analog sensors and IP video share a single timebase, so the order of events is never in doubt.

A record that holds its integrity

Hash-chaining makes any later edit visible, so the log can stand in a class, flag or insurer review rather than only an operational note.

Nothing for the crew to manage

Up to 24 channels record continuously from the moment the unit is installed, with no daily routine to remember and no gaps left to chance.

Built for the fleet you run.

Cargo and container

One record per vessel for operational review and charter evidence.

Tankers and gas carriers

Tamper-evident machinery and navigation history where scrutiny is highest.

Offshore and support

Condition data from hard-working plant, captured through every blackout.

The SEAVAULT recorder unit

One sealed unit, built for the engine room.

A single tamper-evident recorder that captures and time-synchronises every channel on board, and keeps recording through power loss.

Inputs
NMEA 0183/2000, Modbus, analog, IP video
Channels
Up to 24 on one timebase
Integrity
Hash-chained, tamper-evident record
Resilience
Edge buffer through blackout and link loss
Up to 24 channels

Navigation, machinery and video held on one shared timebase.

Hash-chained

A tamper-evident record that reads as one continuous account.

Through blackout

An edge buffer keeps writing when power and links drop.
