IMOS On-Prem - Bunker Curve Parameters
You can include Bunker Curve Parameters in the calculation of fuel consumption for LNG vessels.
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
.
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
To modify a Fuel Type or Group:
Select the Calc check box.
If you want to modify LNG, make sure the Generate LNG rates from FOE check box is cleared.
Ballast and Laden Coefficients C and B are specified based on charter party vessel conditions; specify new values.
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.
