Wondering what is an Electronic Record book?
It’s a digital record of all operations on your vessel, automatically capturing both manually-reported data and sensor-collected data. It also allows crews to log information much easier than before, and keeps your information secure outside of your vessel in the cloud.
We offer marine electronic record books fully compliant with IMO, Marpol, SOLAS and several flag states’ requirements that will streamline onboard event-logging.

Leading the Green Transition
Discover how an Oil & Gas operator from the Middle East leveraged Opsealog’s solutions and achieved 53% decrease in fuel consumption savings, minimized GHG emissions, and reduced maintenance requirements by optimizing engine utilization

From Data to Impact: use case example
Each month, we uncover the true impact behind operational challenges on our Linkedin Page. At Opsealog, every obstacle is a chance to measure, optimize, and improve.

At Opsealog, our #fuelefficiency program combines data insights with offshore operational know-how to optimize maritime operations.
📍In this case, our fuel expert team identified a significant drop in a partner vessel’s performance in transit. The vessel [a PSV, diesel-electric 48 meters in LOA] was transiting using more generators for same speed orders with similar navigational considerations.
After a thorough investigation and onboard inspection, we found multiple propulsion issues affecting the vessel’s performance and fuel consumption. Thanks to this collaboration, we were able to confirm the issue.
The vessel incurred a 15% daily rate penalty for failing to meet performance standards due to the initial lack of transparency.
💲The penalty’s estimated costs are around 3000 USD /day.
This case demonstrates how open communication and proactive management can help uncover and resolve issues significantly impacting operational efficiency and financial outcomes.
