Logbooks keep going
Entries, tasks, comments and attachments are written offline and sent in order. Only signing a day waits for the link.
Continuum · Ship-shore data synchronization
Ship and shore in sync, even without a link
Navatom works in real time. Continuum is the guarantee behind it: each vessel keeps its reports, logbook, manuals and circulars on board, the crew keeps reporting, logging and reading when the connection drops, and every change reaches the office, in order, when the link returns.

When ship and shore change the same thing
The change waits, and the person who made it decides.

One tablet, many hands
The copy belongs to the vessel, so a shared tablet downloads once. Each change is sent under its author’s name only.
It repairs itself at sea
A damaged copy is found, set aside and downloaded fresh, and the changes waiting to send are kept.
Always clear what is waiting
One button shows the state on every app, and its screen lists each pending change and what the device holds.
FAQ
Questions fleet managers ask about Continuum
Does Navatom work on ships with poor or no internet?
Yes, for the work crews do most. With Continuum, each vessel keeps its reports, logbook, manuals and circulars on board, so the crew keeps reporting deficiencies, near misses, accidents and other findings, writing the logbook, and reading manuals and circulars without a connection. Continuum sends the changes made offline in order when the link returns. A few steps wait for the connection, such as signing a logbook day and choosing root causes from the systems Navatom provides.
What happens to a change made offline?
Continuum saves the change on the device and queues it in the order it was made, marked Saved on this device · Waiting to send. When the connection returns, Continuum sends the queue to Navatom and the record shows Saved to cloud.
What if the office edits the same record while the ship is offline?
Every queued change carries the value its author was looking at. If the office changed that field in the meantime, Continuum holds the change and shows its author both values, and the author keeps the server version or applies their change anyway.
How much history does a vessel keep offline?
A vessel keeps 3 years of its deficiency, non-conformity, accident, near miss and technical finding reports, the period a Paris MoU ship risk profile looks back over, with photos and PDFs up to 30 MB each. It keeps 3 years of logbook entries, every manual it can see with files up to 100 MB, and every released circular with its PDFs for 2 years from release.
Which logbook actions work offline?
Creating, editing, completing and deleting logbook entries, starting and ending tasks, and adding comments and attachments all work offline and are sent in order when the connection returns. Signing and unsigning a logbook day need the connection, and tank soundings and instrument readings still need it for now.
Can two people share one tablet on board?
Yes. Continuum keeps one copy of the records per vessel, so a shared tablet never downloads twice. Each queued change keeps the name of the person who made it and is sent under that name only; until its author signs in again, it shows Waiting for its author.
What happens if the offline copy on a device is damaged?
Continuum detects damage in the copy stored on the device, sets the damaged part aside and downloads a fresh copy when the link returns. Changes still waiting to be sent are kept through the repair.
