To open the Bunker Planning form, do one of the following:
- On a Voyage Estimate Column View or Details View menu, click Bunker Planning.
- On a Voyage Estimate Details View:
- On the fuel grid, right-click a line item and then click Details.
- On the P&L Summary, click the Bunker Expenses: link.

- 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.
Optimize Liftings for Cargo
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.
...
- If there are multiple fueling ports (indicated by prices entered) in the itinerary, the Receive quantities are automatically populated with the amount of bunkers needed to arrive at the first fueling port so that the ROBs are equal to the safety margin of the vessel. Then, at the second fueling port, the amount of bunkers are populated such that the quantity upon arrival at the terminating port is equal to the End Quantity specified.
- If you manually enter a lifting quantity, that amount appears blue and is not overridden when the calculation is run again.
- The optimizer calculates in real time; that is, Receive quantities automatically adjust when you change prices.
- The optimizer no longer calculates after the Voyage Estimate is fixed; it is for planning purposes only.
Use Scrubbers
Excerpt |
---|
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/FuelZone 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 IMOS Data Center, click .
