IMOS - Bunker Curve Parameters

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

1. Do one of the following:
   

   • On the Time Charter In Performance tab, click on .

   • On the Time Charter Out Performance tab, click on .

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.
