IMOS On-Prem - Bunker Curve Parameters

You can include Bunker Curve Parameters in the calculation of fuel consumption for LNG vessels.

1. Do any of the following:
   
   • On the Vessel Consumption tab, click .
   • On the Time Charter In Performance tab, click .
   • On the Time Charter Out Performance tab, click .
2. On the Bunker Curve Parameters form, complete the following fields:
   • Speed From: Defaults to the lowest speed in the Speed Consumption Table
   • Speed To: Defaults to the highest speed in the Speed Consumption Table
   • Step Size: Defaults to the difference between Speed To and Speed From
3. To modify a Fuel Type or Group:
   1. Select the Calc check box.
   2. If you want to modify LNG, make sure the Generate LNG rates from FOE check box is cleared.
   3. Ballast and Laden Coefficients C and B are specified based on charter party vessel conditions; specify new values.
4. To recalculate the Speed Consumption Table, click OK.
   • When the table recalculates, rows that do not match speeds calculated based on Speed From, Speed To, and Step are deleted.
   • For each modified Fuel Type or Group, consumption rate = C*EXP(B*speed).
   • When the Generate LNG rates from FOE check box is selected, LNG consumption rate = C*EXP(B*speed)/FOE Conversion.
