IMOS - FuelEU Maritime Calculator
Introduction
What is FuelEU Maritime?
FuelEU Maritime is an EU emissions-related regulation that will go into effect in 2025. The regulation is a technical calculation driven by the greenhouse gas (GHG) intensity of fuel consumed. This calculation generates a FuelEU Compliance Balance that can result in a penalty.
The commercial impacts (penalties) will increase exponentially on general fuel types such as HFO (estimated penalty ~$70/MT), MGO (estimated penalty ~$40/MT), and LSF (estimated penalty ~$50/MT), as the regulation moves to its different stages.
To support elements of this regulation, IMOS now includes a comprehensive FuelEU Calculation in the Voyage Estimator to help drive commercial decisions.
The FuelEU Calculator
The FuelEU Calculator is available on the Estimate level to aid in commercial decision-making regarding the impact of FuelEU. The FuelEU calculation breaks down Consumption, Energy, GHG Intensities, and Compliance Balance by voyage leg, and displays voyage total Energy, Compliance Balance, and Penalty amounts.
Getting Started
This feature requires the configuration flag CFGEnableFuelEU to be enabled and Schema Version 463.
Accessing the FuelEU Calculator from the Carbon Calculator
To access the FuelEU Calculator, start by navigating to Estimates in the Chartering Module. From the Estimate, select Menu → Analysis → Carbon Calculator.
Example estimate worksheet
Menu → Analysis → Carbon Caculator
From the Carbon Calculator, you can select the FuelEU tab located next to the EU ETS tab.
Capturing the Emissions Factors
The Fuel/Lube Table under the Data Center has additional fields to capture the necessary FuelEU Factors per file type. Below are the default values defined by the EU in the published REGULATION (EU) 2023/1805 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL and Veson Nautical’s interpretation of the equation to calculate the WtT CO2eq and TtW CO2eq.
Fuel Type | TtW CO2 | TtW CH4 | TtW N2O | LCV | WtT CO2eq | TtW CO2eq |
|---|---|---|---|---|---|---|
HFO | 3.114 | .00005 | .00018 | .0405 | 13.5 | 3.1689 |
LFO | 3.151 | .00005 | .00018 | .041 | 13.2 | 3.2059 |
MDO/MGO | 3.206 | .00005 | .00018. | .0427 | 14.4 | 3.2609 |
LNG | 2.750 | 0 | .00011 | .0491 | 18.5 | 3.3441 |
These values can be entered by navigating to Data Center → Fuel/Lube Type
The LNG Equivalent check box can be used to indicate an LNG fuel type where LNG is not the defined Fuel Type Code. Selecting this checkbox will apply the Cslip value based on the engine type defined under the vessel only. No other LNG behaviors will be applied.
If the Fuel Type Code is LNG, there is no need to select the checkbox.
If the Fuel Type Code is LNF (In reality LNG), select the checkbox to apply a Cslip factor.
If the Fuel Type is HFO, do not select the checkbox as Cslip is not required for this fuel
LNG with Cslip Factor
The LNG Cslip Factor depends on the LNG Engine as defined in the table below. To capture the Cslip for LNG, the Engine Type can be configured on a vessel.
Configuring the Engine Type on a Vessel
Navigate to Data Center → Vessel → Details Tab. Under the Details tab, there will be a field called Engine Make/Type, allowing for the types defined by the EU to be selected on the engine. Each engine type references the default Cslip value and is included in the FuelEU Calculation.
Understanding the FuelEU Calculator
Unlike EU ETS, which only considers emissions from Take to Wake, FuelEU Maritime looks at the entire lifecycle of the fuel. This is known as Well-to-Wake (WtW), which includes the Well-to-Tank (WtT) phase (this covers the generated emissions from the extraction, cultivation, production, and transportation of the fuel), and the Tank-to-Wake (TtW) phase (this covers the emissions generated during the combustion of the fuel).
How does FuelEU calculate the penalty?
Using the Greenhouse Gas (GHG) Intensity Limit for the year and by calculating the GHG Intensity and Energy Used on Board during the voyage, the FuelEU Calculator determines the penalty using the equation below.
If a ship exceeds the FuelEU yearly intensity limits, there will be a penalty.
GHG Intensity: The amount of CO2, CH4, and N20 emissions per MJ of energy used, expressed in grams of CO2 equivalents
Formulas used
GHG Intensity Limit = 89.3368 (2025-2030)
WtT GHG Intensity - ( MT x 1,000,000 x 'WtT CO2e' x LCV ) / MJ
TtW GHG Intensity - ( MT x 1,000,000 x 'TtW CO2e' ) / MJ
WtW GHG Intensity (GHG Intensity of the Ship) - WtT GHG Intensity + TtW GHG Intensity
Total Energy - MT x 1,000,000 x LCV = MJ
Compliance Balance (MT) - (GHG Intensity Limit - GHG Intensity) x MJ / 1,000,000
Penalty - (GHG Intensity Limit - GHG Intensity) / GHG Intensity x MJ x Energy Penalty
Energy Penalty = 0.058
Compliance Balance and Penalty
The goal of the calculation is to drive two metrics: Compliance Balance and Penalty.
The Compliance Balance is the amount of equivalent carbon in grams (g/CO2eq). The FuelEu Calculator displays this in MT (x 1,000,000) as the unit is more intuitive.
The Fuel EU Penalty is the cost associated with the compliance (Compliance Balance x Energy Penalty = $)
Negative Compliance: Fuel EU Penalty. The fuel consumed during the voyage was over the compliance limit.
Positive Compliance: No Fuel EU Penalty. The fuel consumed during the voyage was compliant and created a compliance surplus.
