Around 8 knots and above, the fuel consumption goes through the roof. Yet in most ports, between 40% and 70% of all light-sailing, i.e. mobilization and demobilization is done at speeds over 8 knots and even up to 11-12 knots, often for no good reason. The impact of speeding on fuel consumption is theoretically well understood, but very much underestimated. A CO2 reduction estimate is often the first step before a full cii calculation. By showing how speed, light-sailing, and operational behavior affect fuel burn, the calculator helps tugboat operators understand where maritime CO2 emissions can be reduced and where better activity data is needed for scope 3 emissions shipping reports, customer disclosures, and internal decarbonization targets. I.e. in most operations there is very significant potential for fuel and CO2 saving for slower speeding. Executive answer ## What is the best first step for CII and CO2 reduction? For tugboat operators, the practical first step is to estimate where fuel waste happens before building a full CII calculation workflow. Light-sailing speed, waiting time, and operational behavior often create the clearest CO2 reduction opportunities.

We use a combination of AIS data, RPM readings, and machine learning models to estimate fuel usage with high accuracy. Can I use the system if I don’t have engine sensors installed? Yes, there are multiple setup options—including models trained on operational data alone. How accurate is the fuel data? In most use cases, the combined model of contextual and RPM data gives a near-exact estimate of actual fuel consumption. How does this help with emission tracking? We provide detailed CO₂ emission reports by job, tug, or customer to support environmental targets. Can I see the fuel usage across different benchmarks? Yes—the system includes captain tables and tug performance data for internal comparisons. Does this help with regulatory compliance? Yes—the insights help operators monitor and document fuel use and emissions. It makes it easier to prepare the scope 3 emission reporting. What hardware is needed to get started? Depending on the setup, you may need a data logger, an AIS receiver, and optionally, a temporary fuel meter or RPM connection. Is installation disruptive to operations? No—temporary setups can be installed with minimal interruption, and permanent options can be scheduled flexibly. Get a Demo ## See FuelExplorer in Action!
