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 in the Carbon Calculator 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. You may also need to update your schema.

Step 1 – Inputting Fuel/Lube Types

To start, you’ll need to input your fuel/lube types. In the Data Center, navigate to Fuel/Lube Types (under the Vessels category).

Step 2 – Capturing the Emissions Factors

The Fuel/Lube Table under the Data Center has additional fields to capture the necessary FuelEU Factors per fuel 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.

Please review these factors with verifiers.

These values can be entered by navigating to Data Center → Fuel/Lube Type

The LNG Equivalent check box is used to indicate an LNG fuel type. 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 when selecting this checkbox.

• If the Fuel Type Code is 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

Optional Step – Capturing Cslip for LNG

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.

Step 4 – 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, which allows 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.

Using the FuelEU Calculator

Accessing the FuelEU Calculator from the Carbon Calculator

To access the FuelEU Calculator, start by navigating to Estimates in the Chartering Module. Select an estimate, then from the Estimate worksheet, select Menu (…) → Analysis → Carbon Calculator.

Customizing the Calculator

These customizations may require a schema update.

Overriding the total penalty values

To override the penalty values either in EUR or your base currency (shown as USD here), you can input a new Agreed Penalty amount. If you update the Agreed Penalty (EUR) or Agreed Penalty in your base currency, the other field will auto-populate.

If you want to, you can override both fields and input a new amount for each.

Overriding the exchange rate between EUR and the voyage's base currency

If you want to override the exchange rate (e.g., you want to use yesterday’s exchange rate for your calculation), you can change it using the the Exchange Rate (EUR to [your base currency]) field.

If you change the exchange rate, Agreed Penalty calculation for your base currency will be automatically updated.

Reporting on Aggregate Values

The FuelEU Calculator also captures the following aggregate values:

• Total Energy

• Compliance Balance (MT)

• Penalty (EUR)

You can report on these aggregate values by navigating to Analytics → Report List → [your report name]. If the FuelEU Agreed Penalty fields were used to override the FuelEU Penalty amount in the FuelEU tab of the Carbon Calculator, this will be shown in the report.

Invoicing FuelEU Maritime Costs

Once a voyage is complete, you may want to include FuelEU Maritime costs in your time charter (TC) invoice. Take the following steps to invoice FuelEU costs.

Billing and Source Codes

The FuelEU Voyage item will be assigned the bill code VFEUE. Source codes are TCIP for payment and TCOB for billing.

The currency used for FuelEU Maritime costs in TC In invoicing is the base currency amount for the FuelEU tab in the Carbon Calculator.

Step 1 – Navigating to the Time Charter (TC) In List

From the main menu, under Chartering, select TC In – List. From the TC In List, choose a time charter by selecting the TC Code. This will open the Time Charter In form. From there, select Make Payment.

Step 2 – Making a Payment

Follow the steps in IMOS - Time Charter Paymentfor making a payment in the Time Charter Payment form. Once you reach step 3, select Create/Add Details to select line items to add to the payment in the Item Select form.

Step 3 – Adding FuelEU Line Items

From the Item Select form, check the box for Fuel EU Voyage. Then, select OK.

The Item Select form will close and you will be back on the Time Charter Payment form. The FuelEU Voyage item will be assigned the bill code VFEUE.

Step 4 – Selecting the Voyage

From the Time Charter Payment form, select the Voyage Number (Voy No.) of the voyage you want to invoice.

Once a voyage is selected, the Amount defined in the FuelEU tab of the Carbon Calculator will appear under the Amount column. This amount cannot be edited from the Time Charter Payment form. Select the Save button to save the invoice.

How Does the FuelEU Calculator Work?

Unlike EU ETS, which only considers emissions from Tank 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 of the year = 89.3368 (2025-2030)

• GHG Intensity of the Ship (WtW GHG Intensity) = WtT GHG Intensity + TtW GHG Intensity

  • 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

• Total Energy (MJ) = MT x 1,000,000 x LCV

• Penalty per energy used (EUR/MJ) = 0.058

Total Penalty = (GHG Intensity Limit - GHG Intensity) / GHG Intensity x MJ x Energy Penalty

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.

• Compliance Balance (MT) = (GHG Intensity Limit - GHG Intensity) x Total Energy / 1,000,000

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.
