We4Sea helps ship owners make better decisions, based on detailed, data-driven insights on all aspects of their operations — technical, logistical and operational — that impact their fuel efficiency.

With a 30+ experience in the maritime industry, we know how difficult monitoring your vessels can be. So we developed a new tool, with the aim to make fuel efficiency easy. Based on Big-data technologies, we can monitor and report on any vessel, within 24 hours.

We provide a full web service, that provides fleet owners with access to operational insights without the need for costly on-board installations or port-visits.

With an unrivalled short set-up time, an up to date dashboard and in-depth insight into the effect of new technologies on your fuel-efficiency, We4Sea is the perfect partner for analyzing and improving your fleet!

Try us! Our solution offers great advantages:

  • Full insight into fuel consumption and ways to optimize your vessels
  • No need for additional hardware on-board. We only use existing data sources.
  • We include weather effects. Using data of currents, wind and waves, we eliminate these effects in our calculations. Allowing you to benchmark your fleet.
  • We can include historical operational data. No need to wait to get a better insight.
  • Future-proof. Our solution is independently certified for EU-MRV CO2 reporting.


Our performance monitoring platform allows you to follow the performance of your ship, in real-time. We combine location and speed data of the ship, meteo and seastate data, using our unique Digital Twin Technology. Our Digital Twin simulates the instantaneous performance of the ship and each of its components. Fuel consumption and emissions are presented and can be calibrated with actual on-board measurements.

The performance monitoring tool gives insight in the actual usage of your fleet, the relative performance of your fleet compared to similarly sized vessels and an overview of well-performing components and “efficiency killers”. This is the first step in our joint journey towards efficiency improvement.
