The Vessel Consumption tab includes the following sections:
In Port Consumption Table
- When adding a new Low Sulfur fuel type to a Vessel that has an existing High Sulfur type defined, Port/Sea Consumption rates default to being the same as the High Sulfur consumption rates, if the new Low Sulfur fuel type is in the same Group as the High Sulfur fuel type on the Fuel/Lube Types form.
- When a Vessel Type is selected, and no fuel types are defined yet, the system defaults the Fuel Types, Units, and Grade according to the Vessel Type. If the vessel has not yet been used, changing the Vessel Type gives you the option to replace the existing fuel types with the default fuel types defined for the Vessel Type.
- When the fuel type is H, and an L fuel type exists in the vessel and is in the same Group on the Fuel/Lube Types form, you can copy consumption figures from the HS/LS corresponding fuel type. Right-click the Fuel Type and then click Copy consumption.
For LNG Vessels
Reliq, GCU/Steam, and Meter Adj consumption table columns replace Heat, Heat+, and Heat++.
You can include Bunker Curve Parameters in the calculation of fuel consumption.
Speed Consumption Table
- Figures are separated into Ballast (B) and Laden (L).
- When the Vessel Type has Restrict Speeds enabled, the speeds available are only those corresponding to the specific Ballast/Laden mode.
- In an Estimate or a Voyage, if the designated speed does not exist in the vessel details, IMOS uses the consumption data of the closest speed available (minimum or maximum).
- If conflicted, the fuel grade from Fuel Zones in the Data Center takes priority over consumption.
Variables and Safety Margins
Enter variables and safety margins for the vessel.
Beaufort, Sea State, and Sea Swell options are defined in the Data Center.
|Enable Vessel Bunker Grade|
|Enable Legacy IFO Top Off Calc|
For LNG vessels, relates to the calculation of the amount of IFO (or other designated "FOE" fuel type) needed in order to accelerate to a given speed higher than the NBOG speed when in dual-fuel mode. When this config flag is enabled, this amount is calculated as the difference between (a) the IFO consumption at actual speed and (b) the FOE equivalent of the LNG consumption at the NBOG speed. When this config flag is disabled or by default, this amount is calculated as the difference between (a) the IFO consumption at actual speed and (b) the IFO consumption at NBOG speed.
|Enable Default Ending Rob Constants|
An additional constant representing a default ending bunker quantity will be added into the Voyage Estimate maximum lift calculation in cases where the initial bunker quantities are not specified in the estimate.
|Enable Vessel Scrubbers|
When enabled, the Scrubbers Active field is shown on the Vessel Consumption tab.
