- Sea Consumption is calculated based on the specified consumption rate for the speed associated with the sea leg.
Port Consumption is calculated based on the time used for loading or discharging, basis SHINC, at the Load or Discharge consumption rate specified for the vessel. Additional time in port is calculated basis the vessel-specified Idle consumption rate. This additional time is Turn Time and time spent in port during weekend clauses. In addition, you can add extra time in port: The related columns are XP and Dem, which also count as Idle time.
For LNG vessels, the LNG detail tab includes additional fields for **OV Estimates only (not **TO Estimates).Anchor LNG LNG - To back-calculate the optimal discharge quantity based on heel, right-click a discharge port and then click Calculate Disch Qty based on Heel.
Enter the Heel desired upon arrival and then click Calculate. To save the calculated Discharge Quantity, click Save.
- To back-calculate the optimal discharge quantity based on heel, right-click a discharge port and then click Calculate Disch Qty based on Heel.
- For Bulk carriers, there is an option for each port call to indicate whether the vessel will be using its own cranes. If not, it consumes at the Idle consumption rate.
Note: To show cleaning consumption at sea, CFGEnableOpsEstSeaCleaning needs to be enabled. This will add Clean Cons and Heat Sea columns into the Bunker Planning of Estimate. The values will be captured in the P&L Estimate in Bunkers' section.
For a type **OV voyage, you can optimize liftings based on bunker prices at fueling ports specified in the Voyage Estimate Itinerary. You can also take into account the freight rate of one of the cargoes on the Voyage Estimate to determine if it is more beneficial to lift more bunkers in place of that cargo or vice versa.

When the Use Scrubbers check box is selected, low sulfur bunkers are not used for at-sea consumption within ECA zones. Instead, high sulfur ("H"-type in the Vessel) bunkers is consumed. In-port consumption still adheres to Vessel/Fuel Zone bunker configuration if a given port is within an ECA zone. |
Fuel Zones
For Estimates that are not already using Fuel Zones to calculate bunker consumption and have unsailed ports, a Use Fuel Zones button appears in the lower left corner. To recalculate estimated bunker consumption and cost based on information entered in Fuel Zones in the Data Center, click Use Fuel Zones.
If you have configured a Fuel Zone Set, you can select it, rather than the Default set, at the bottom of this form.
Why Isn't my Estimate showing consuming correctly?
There are a few places you can check to find out why a vessel isn't consuming as planned.
- Open the bunker estimate and check the Fuel Zone Set
- Check the Vessel Details to confirm your fuel types are configured correctly. (Vessel Fuel Zone Set can be entered here)
- Within the voyage bunkers, make sure there is enough Primary fuel to complete the voyage. If there is not, the system with calculating with a backup fuel unless there is not enough fuel for the backup Fuel to complete the voyage or the disable backup fuel checkbox has been selected. In this case, the system will have the Primary fuel consume the entire voyage and the backup fuel quantity will be untouched. This is based on the assumption that a bunker lifting will happen, clearing the need to use the backup fuel for the voyage.
