IMOS On-Prem - Fuel Zones

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.

In the Data Center , under Ports and Areas, click Fuel Zones.

Creating a Fuel Zone Set

To create a Fuel Zone Set:

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 can be selected to consume in an ECA Zone when (cons rate only) 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.

ECA Routing

To set up ECA routing, do any of the following:

• On the Voyage Estimate (Column or Details view) or Voyage Manager, set ECA Routing/Avoidance:
  

  • Default: Uses the vessel's default routing preferences specified on the Routes tab in the Vessel form.
  • Disabled: Uses the most direct Distances route.
  • Enabled: Reroutes the vessel around the region.

• On the Veslink Distances or Voyage Reporting map, select Minimize ECA Routing.

• In Veslink Distances Map Settings, there is a Minimize ECA Routing check box. When selected, routes will be calculated to minimize travel through ECA zones.

If a port is located within a Fuel Zone, its name appears: 

• A port is assigned to the smallest Fuel Zone within which it is located. For example, HUENEME is assigned to USA 25NM zone, but it is also located in US 200NM:
  
• To override the low sulfur status, select the Use High Sulfur Fuel check box. Any future in-port consumption at that port uses high sulfur fuel.
• For other ports, the field is blank: 
  • To specify a port as a low sulfur area, select the Low Sulfur ECA check box.
  • You can also specify an Emission Control Area as a low sulfur area, automatically setting the area and all ports in it to low sulfur. You must have the most recent Distances update installed. To confirm, make sure that ECA Fuel Zone ports are in your Port List, and confirm that the Low Sulfur ECA check box is selected in all of them.

ECA Fuel Zones

• ECA-AUSTRALIA

• ECA-BRAZIL

• ECA-CHINA: When using this fuel zone, set YANGTZE RIVER DELTA, and YANGTZE RIVER DELTA 10OCT18 as inactive. ECA-CHINA incorporates all of these zones together so the others are no longer needed. When keeping them all activated this will cause duplicated passing points in the itinerary.

• ECA-KOREA PORTS

• ECA-MALAYSIA

• ECA-SUEZ CANAL

• ECA-TAIWAN

• ECA-YANGTZE INNER RIVER

• HAWAII 200NM

• ICELAND

• NORTH SEA

• PANAMA CANAL

• PUERTO RICO 200NM

• USA 200NM

• USA 24NM

• WORLDWIDE: This zone is used to set the Fuel Types to be consumed in ports that are not located in any of these Fuel Zones but have the Low Sulfur ECA check box selected. This includes any historic Estimates created without Fuel Zone information. It should include only Fuel Types that were being used for low sulfur consumption before configuring Fuel Zones (and no cons rate only); otherwise, the consumption rates and types will change on Estimates/voyages created before Fuel Zones were enabled.

• YANGTZE RIVER DELTA

• YANGTZE RIVER DELTA 1OCT18

• ECA-HAINAN

If Worldwide/Worldwide (Non-ECA) or other ECA zones are missing from the Fuel Zones table, they may have been deleted (by right-clicking on the row) or the distance file is not up to date. These values can be populated into the system by upload the Distances file. The latest Distances file can be found at the Client Center or can be requested through our Veson Support Portal.  

Specific Fuel Zone Consumption within ECA Zones: 

 IMO 2020 functionality allows for flexibility in the Fuel Zone set-up. Regardless of scrubber presence on a vessel, calculations are dependent upon which fuels are consumed in each specific zone (including "Worldwide", and "Worldwide Non-ECA"). This can be configured once in Fuel Zones so that additional changes do not need to be made.

Voyage Fuel Zones Example

Fuel/Lube Types

In this example, the following Fuel/Lube Types are configured:

Fuel Zones

The following Fuel Zones are configured:

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.

Based on the defined Fuel Zones, the vessel will consume:

• IFO when outside an ECA zone
• LSF when at sea within the ECA - US 200NM Hawaii, ECA - US 50NM PUERTO RICO, and NA 200NM zones
• LSG when at sea within the SECA - NORTH SEA and USA 25NM zones
• MDO when in port and for Miscellaneous Consumption within the ECA - US 200NM Hawaii, ECA - US 50NM PUERTO RICO, and NA 200NM zones
• MGO when in port and for Miscellaneous Consumption within the SECA - NORTH SEA and USA 25NM zones and when outside an ECA zone (WORLDWIDE)

Notes:

• Another fuel type with grade L could be added to the Vessel form, but it will only be consumed if it is also on the Fuel Zones form.
• Fuel types marked as General (G in the G column) are consumed at a combined rate if they are specified to be consumed within that Fuel Zone along with a Low Sulfur fuel specified as (cons rate only).

Voyage Itinerary

This voyage has the Example Set specified in the Fuel Zone Set field at the bottom of the Voyage Bunkers form: .

The voyage loads in Houston and discharges in Rotterdam with this itinerary:

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.

Frequently Asked Questions

Can I turn Fuel Zones on/off?

Fuel Zones cannot be turned off once they are in use. At this time, you cannot set effective dates such that Fuel Zones are only in effect if the Commence Date is greater than a certain point in time.

To inactivate a Fuel Zone so that it cannot be used in new Voyage Estimates and Voyages, select its Inactive check box.

If I make changes to the Fuel Zones form, does it refresh on voyages and Estimates that have already been created?

No, existing voyages and Estimates do not automatically update.

• For Estimates and voyages that were created before Fuel Zones were enabled, click the Use Fuel Zones button on the Voyage Bunkers or Bunker Planning form to update them. After that single click, the button does not appear again, because it does not trigger again every time Fuel Zones and consumption are changed.
  • If the voyage is linked to a TC, confirm that the contract is burning the correct fuel according to the fuel zone update. If the fuel matrix on the TC does not include the fuel type, it will not be picked up on the estimate or voyage.
• After Fuel Zones are enabled, any change on an Estimate or a voyage that triggers a recalculation of the voyage or Estimate causes a recalculation of the fuel consumption/cost based on the current Fuel Zones setup.
• Changes to Fuel Zones do not automatically refresh existing Estimates and voyages, but changes will be reflected on all Estimates and voyages created after enabling Fuel Zones.

Why is the Use Fuel Zones button not appearing on a specific voyage?

The Use Fuel Zones button only appears on Estimates and voyages that were created before Fuel Zones were enabled, and once clicked will not appear again on that particular Estimate/voyage. Also, the button will not appear on voyages that do not pass through the relevant ECA zones and ports, or voyages that have already been Completed or Closed.

What happens when I click the Use Fuel Zones button?

When you click the Use Fuel Zones button, Bunker Consumption and costs refresh on the Estimate or voyage based on the consumption configuration specified on the Vessel and Fuel Zones forms. The P&L is also recalculated to reflect this change. Voyages with manually entered Distances will be changed to use the automatic calculation.

Why does my itinerary have duplicate passing points?

When new fuel zones are enabled, the old ones remain for historical reasons. As a result, you need to change what fuel zones are Inactive to ensure the most up-to-date port itinerary.

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:

1. Create a Fuel Zone Set with a descriptive name, for example, Legacy.
2. Enter the setup to be used on historic records.
3. Select this Legacy Fuel Zone Set at the bottom of the Voyage Bunkers and Bunker Planning forms.
