Digital nautical log books
The easiest way to record daily activities on board ships.

Digital log book system
Manage logs easily on board with a digital log book system to replace your paper log books, including log books required by MARPOL, for example, oil, cargo and garbage log books. By digitalising ship log books, all the information is available and visible online immediately for fast and accurate reporting, both on board and ashore. OneLog is intuitive and replicates paper logs to make it quick and easy to get up and running and record daily activities. The move to digital log books is very easy and you don't need to buy any additional hardware to make the upgrade.

Emissions Reporting now in OneLog
We now have an emissions reporting Log Book! This addition provides a comprehensive overview of essential indexes including CII, EEXI, EEOI, AER, Poseidon, and Sea Charter. Easily input fuel usage and distance sailed, and watch as automated reports are generated effortlessly. Say goodbye to scattered data – with OneLog, everything is streamlined and organised for efficient monitoring and analysis on board your ships. Experience simplified emissions reporting with OneLog, your trusted software solution for recording daily activities on board.

Advantages of OneLog

Automatic backups
You can configure automatic backups of between 30 minutes and 24 hours to keep data safe and save you time doing manual backups.

Accurate logs
Human error is reduced as log data entered is legible, eliminating mistakes made due to illegible handwriting and potential errors are highlighted.

Accurate audits
Deleted entries are saved in the history and shown as crossed to replicate a paper log book and keep your records accurate.

New log books immediately
By digitally recording your daily onboard activities, you are removing the need to print and courier paper logbooks to vessels. Digital log books are available instantly, so you do not need to wait for the next new log book to arrive from shore. We are always working to add new types of log books to provide a fully digital log book system.

Reduced administration
Some log books have to be stored for ten years, taking up valuable space on board. Replace them with a digital system that saves space on board and saves admin time checking stock levels and reordering paper replacements.

Flexible system
OneLog fits to the specific needs and infrastructure on each vessel – it works either all on one computer, where OneLog and the collected data are stored together. It can also run on multiple computers and collected data is stored on a server to give multiple access points.
