IMOS - Consumption Tab - Vessel

Home > Data Center > Consumption Tab - Vessel


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

ReliqGCU/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, the Veson IMOS Platform uses will linearly interpolate between the available consumption data within the Ballast and Laden categories.
  • 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.


Related Configuration Flags
Name/FlagDescription
Enable Vessel Bunker Grade
CFGEnableVesselBunkerGrade

Specifies the Fuel Grade in a G (Grade) column on the Vessel or Time Charter In/Out form, which defaults the value on the Bunker Requirement; it can be overridden but is required for Confirmed status.

Enable Legacy IFO Top Off Calc
CFGEnableLegacyIFOTopOffCalc

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
CFGEnableDefaultEndingRobConstants

An additional constant representing a default ending bunker quantity (Ending Bunker ROB Margin on the Vessel form) will be added into the Estimate maximum lift calculation in cases where the initial bunker quantities are not specified in the Estimate.
