The Route calculator in Netback analytics now offers the option to include an LNG voyage when estimating transport costs for routes starting at an LNG export terminal. This lets you calculate the shipping leg to a European import terminal alongside the onward European gas route, without needing to combine results from the Voyage Calculator manually. Shipping costs include:
Charter hire
Boil-off cost
EU ETS CO₂ allowance cost
Port charges
Other voyage-related costs
Build a route
Open the Route calculator tab in Netback analytics.
Select an LNG export terminal as the origin and an LNG import terminal as the destination or next stop of your route. You can end your route there or select further European land markets. Note: you can select terminals on the map or enter them in the route fields.
If needed, specify channels to avoid. Note: this field is optional.
Review the LNG Voyage and Unload section under Parameters, that appears above the existing route inputs.
Adjust the voyage assumptions, then calculate the route.
On the map, green terminals indicate LNG export terminals and orange terminals indicate LNG import terminals in Europe. A US export terminal to a European import terminal is a common use case, but the origin does not have to be in the US; when moving around the map, you will see export terminals across the Americas, MEA, and APAC.
Notes:
When a route starts from an LNG export terminal, the next destination must be a European LNG import terminal.
Charter-hire costs are calculated for the round voyage, covering both the outward and return legs of the vessel journey. Other voyage costs are calculated for the one-way laden journey to Europe.
The map displays active terminals, while planned and decommissioned terminals are not shown as available route selections.
Set LNG voyage parameters
All shipping parameters can be configured, though default values are provided to calculate a route immediately, if required. These include:
LNG tanker and capacity
Freight costs
Speed
Boil-off rate
Select the gear icon — 
— that appears next to the LNG Voyage and Unload header after selecting your desired terminals to input additional parameters, split across:
Port calls: days at load, load port charges, days at unload, and unload port charges
Fuels: fuel mode, boil-off, and boil-off price
Commercial: charter commission, sea margin, and EUA unit price
Conversion details: currency, tariff units, expansion factor, temperature, GCV, and GCV units
Port charges are pulled from the Kpler database. The default model uses boil-off gas only; other model options are available.
Check the assumptions before using a result. In particular, the default boil-off rate and charter-hire values are provided as editable defaults rather than values drawn from an external source. If your organization uses its own assumptions, enter them before calculating.
Understand the results
The calculated result has two sections:
Section | What it covers |
LNG voyage | The shipping leg from the export terminal to the European import terminal. It shows one voyage path, with a total cost and a breakdown that includes items such as charter hire, commission, freight, and port charges. |
Route | The onward route from the European terminal through the gas network to the selected market. This is the existing Route calculator functionality and may show multiple routes, depending on the path and capacity types. |
The LNG voyage section shows one result, not a choice of alternative shipping paths. The calculated route also returns a box to the right that outlines the LNG voyage, including the return leg. The onward European route section continues to work as before.
Review currency conversion and calculation details
When calculating the LNG voyage, a series of assumptions are noted via the information icon — 
— at the top of the table. The assumptions are updated daily (where applicable), or at based on the latest available data, and are specific to each individual voyage.
Below are example assumptions for an LNG voyage at the start of November 2026, transiting Bethioua → Cartagena (ESP) → Bethioua:
LNG voyage freight is priced in USD and converted at today's ECB rate, as the grid legs are, 1 $ = 0.8902 € (ECB, 2026-10-21); each route adds it in a delivered cost below its route total.
Charter hire is based on the return voyage: laden to the discharge terminal and ballast back to the load port. With boil-off charged on the laden leg and the days in port only, the ballast leg adds hire but no fuel.
Grid costs are priced for November 2026, from the calculated arrival on 2026-11-02, on the cargo volume left after boil-off.
The vessel is assumed to burn boil-off gas only, so no bunker fuel is charged. Switch the fuel mode to include fuel oil and ECA MGO.
Boil-off is valued at the PVB M1 hub price in USD/MMBtu.
Boil-off includes the days in port as well as the laden crossing, so it is charged on the same volume deducted from the delivered cargo. The voyage calculator charges the crossing only, so its boil-off cost is lower by one day of boil-off per day in port.
Port charges are Kpler's average LNG rates from port-charges data, updated 2026-04-23: $178,784 for loading at Bethioua and $136,000 for discharging at Cartagena (ESP).
EU ETS covers the laden leg only, as the voyage calculator prices a one-way voyage. Allowances come from the emissions service, which scopes them by the ports at each end, and are estimated as in the voyage calculator: from the boil-off rate on boil-off gas alone, otherwise from the daily fuel-oil burn.
Charter hire, the boil-off rate and the daily burn rates have no data source and use editable defaults.
