About the LNG Module

For non-LNG trades, changes in fuel and cargo quantities on board are typically independent of one another. For LNG voyages, however, one of the fuels on board is also the cargo. Fuel transactions affect cargo quantities and vice versa.

The LNG module supports LNG shipping and trading workflows by linking LNG fuel and cargo tracking in IMOS to help users calculate boil-off. LNG is entered into IMOS as both a cargo and a fuel, and any changes to LNG (fuel) or LNG (cargo) quantities are updated in both.

LNG Workflow

With the LNG module, you can follow the standard IMOS workflow with some modifications:


In the Data Center, set up LNG-specific IMOS records.

  1. In the Vessel form, create a vessel of Type code L (LNG Carrier); an LNG tab appears.

  2. Create the Cargo Name and Fuel/Lube TypeLNG.


In Chartering, do any of the following:

  • Manage LNG contracts.

    • If a vessel's Fuel Warranty Table is other than None, in TC In and TC Out contracts, record parameters related to vessel performance warranties in a Warranty tab.

  • Create LNG Voyage Estimates.

    • Specify Fuel Consumption Mode for each LNG voyage leg.

    • On the LNG detail tab of the Bunker Planning form:

      • For **OV Estimates only, enter Max Lift and Max Discharge.

      • You can back-calculate the optimal discharge quantity based on heel.


In Operations, manage LNG voyages.

  • On the Operations tab of the Voyage Manager, specify Fuel Consumption Mode for each LNG voyage leg.

  • In the Voyage Bunkers form, complete additional fields on the LNG detail tab.

  • Automatically capture data from LNG voyage reports using Veslink.


In Financials, close LNG voyages.


In the Report Designer, run performance reports to benchmark against vessel/Time Charter LNG consumption curves.

Display Cost Per MMBTU

If enabled, then for vessels of type L (LNG), the Estimate and Voyage P&L both display the cost per MMBTU (in addition to the usual TCE figure).
