A bunker order can efficiently be added directly from "Booking And Operations" module (in your java client VMS) when having a port call in focus. Either based on the bunker estimates registered, or straight as a bunker order requirement.
Select the port call where you are bunkering and click the "Create new Bunker Order" button from the menu.
A dialog will show a bunker order with the details filled out from the estimates, if there are no estimates please fill in all the details of the bunker order such as Bunker Type, Min/Max quantity, assumed bunker price and supplier.
If you add estimates for several bunker types, all types will be defaulted when you create a bunker order.
NOTE: Defaults will not be set for port calls that already have bunker order tied to it.
