Note: You must have the Fuel Zones Module Right selected, under Ports and Areas in the Data Center.

The Fuel Zones form is used to specify estimated/projected low sulfur consumption for different ECA Fuel Zones. Consumption is specified in sets, and can accommodate different ECA regulations, different Vessel Types, and other factors. You can create multiple Fuel Zone Sets, including a Global Default Set, and apply them to specific vessels, Vessel Fleets, Vessel Types, Estimates, and voyages.

...

1. Type a Name and Description for the Fuel Zone Set.
   
   • Default: Select to make this Set the Global Default.
   • Inactive: Select to make this Set inactive.
2. For each ECA Fuel Zone, click in a cell and select from the list that appears, to specify the low sulfur Fuel/Lube Types (marked L in the G column) to be consumed in each of the categories:
   • Propulsion at Sea (Propulsion/Aux.)
   • Consumption in Port (L/D/Idle)
   • Misc. Consumption (Heat/IGS/Etc.)
     
   • (cons rate only): In some ECA Zones, one Fuel Type must be consumed at its own consumption rate plus the consumption rate of another Fuel Type. To consume the first Fuel Type at the rate of both added together, select one Fuel Type plus one (cons rate only) Fuel Type. All Fuel Types can be used as (cons rate only). Only one Low Sulfur Fuel low-sulfur fuel can be selected to consume in an ECA Zone when (cons rate only) Fuel  fuel is selected.
3. Save the Fuel Zone Set.

• If you have not defined a specific Set for an Estimate or a voyage, a hierarchy determines which Fuel Zone Set to automatically apply.
  1. The Set specified on the Vessel form is applied.
  2. If there is no Set specified there, the Set from the Vessel Types form is applied.
  3. If there is no Set defined on either form, the Global Default Set is used.
     To use a Fuel Zone Set other than the one chosen, select it in the Fuel Zone Set field on each Voyage Estimate and voyage.
• When a route between two ports crosses more than one Fuel Zone, a Passing Point is added to the itinerary to indicate the entry to the next Fuel Zone.
• If multiple Fuel Types are defined for a given Fuel Zone, and the vessel is carrying those Fuel Types, they will be burned simultaneously.

• If a Fuel Zone and a consumption type are set with Fuel/Lube Types, the relevant ports/sea legs will only use those Fuel Types. If not, all the available LS Fuel Types defined on the Vessel form will be used for those ports/sea legs.

Vessel Form Consumption Tab

The Vessel form Consumption tab includes all the configured Fuel/Lube Types: IFO and the low sulfur fuels LSF, LSG, MGO, and MDO.

...

As the vessel nears Rotterdam, it crosses into the SECA - NORTH SEA zone. This passing point is automatically added to the itinerary; a passing port is added when the vessel is moving into an ECA zone. The passing point signifies that the vessel is switching to consume LSG, the low sulfur fuel type specified on the Fuel Zones form.

...

Fuel zone updates are regulated by deactivating older versions to avoid duplicate passing points in a voyage itinerary.

Legacy Fuel Zone Set

If you began using Fuel Zones before the 2015 ECA changes, the modifications made to your Fuel Zone configuration may have changed estimated bunker consumption in historic records. To create a Legacy Fuel Zone Set with pre-2015 Fuel/Lube Types and use it on historic records:
