Home > Bunkering > Debunkering Workflow
Debunkering is the process of offloading bunker fuel from a vessel. In IMOS, you can manage debunkering in the following ways:
Performing Debunkering
To perform debunkering:
-
Open Port Activities by right-clicking the debunkering port in the Voyage Manager Itinerary.
-
In the bunker information grid, enter the fuel quantity to be debunkered as a negative amount under the Received column of the respective bunker type.
-
Check if the same quantity is entered in the Activity Reports.
-
Open the Bunker Liftings form and add the price for the debunkered amount.
-
Right-click the lifted line and then click Create Invoice.
Note: Debunkering quantities recorded in Activity Reports must be covered by a Bunker Invoice. If a debunkering quantity in an Activity Report is not matched to a Bunker Invoice, IMOS generates a voyage validation error to alert you that the quantity needs to be matched. To resolve the error, create a Bunker Invoice for the debunkering quantity as described in steps 5–6 above.
-
On the Bunker Invoice, click to add a new row with invoice details like fuel Type, Inv Qty, and Basic Prc.
-
Post the Bunker Invoice and review the Voyage P&L details. Debunkering adjustment is visible in Actual column.
Note: The Bunker Invoice will is be recognized as Payable, and sold bunkers will be represented by negative values in the invoice description.
-
Make a payment to the Bunker Invoice that was posted. The P&L values remain the same.
-
From the Bunker Liftings form, run the Bunker Details Report to see if the debunkering has taken place.
-
Upon voyage completion, run Voyage Period Journals affect the Posted and Cash In/Out columns.
-
Review the P&L and note that debunkering has successfully affected the Actual, Posted, and Cash In/Out columns.
Choosing a Bunker Lot to Debunker
In a voyage with multiple bunker liftings, you may want to perform debunkering for a specific bunker lot. IMOS gives you complete control over which bunker inventory you want to sell by providing a linkage between the debunkering lifting and the available bunker lots.
To make this linkage, a Bunker Lifting Selection drop-down menu appears for you to pick a bunker lot to debunker when entering in a negative bunker quantity:
After the bunker lot is chosen, you can confirm your selection by hovering over the negative quantity. It should tell you which bunker lot you have chosen:
If you choose the wrong bunker lot to debunker, you can delete the negative bunker quantity and re-enter it. That brings up the Bunker Lifting Selection once again for you to select the bunker lot in which you want to debunker.
