An additional zone has been added: Worldwide NON-ECA. This encompasses all waters and ports that are not in ECA zones, and are not marked as Low Sulfur. The Worldwide Zone encompasses ports that are not in ECA Zones but are marked as Low Sulfur.The Fuel Zones form includes two separate configurations for vessels that are scrubber fitted and those that are not. The Non-Scrubber tab functions the same as the previous Fuel Zones. Both Non-Scrubber and Scrubber tabs allow H (High Sulfur) and G (General) Fuel Types to be selected, instead of only L (Low Sulfur) Types.

After making changes in the fuel zone set, make sure to close the estimate and reopen it to see the new calculated values. |
Scrubbers
The IMO 2020 regulation allows vessels to burn high-sulfur fuel as long as the vessel is fitted with and using a scrubber. Port Authorities around the world will determine their own regulations for permission of scrubber usage at the port. To accommodate the regulations, Veson Nautical is adding the selection of the types of scrubbers on both the Vessel (in use) and Port (allowed) levels.

When configuration flag CFGEnablePortFuelAvailability is enabled, a Fuel Type/Grade Availability grid appears on the Port form, in which the Fuel Types and Grades that are available at the port can be captured.  These fuels appear when you hover on ports in the Estimate and Voyage map views. |

Define compliant and high-sulfur fuels:
Since the vessel has scrubbers, she will most likely continue to consume and stem 3.5% fuel, configured as an H type. As such, there is no need to define compliant fuels for this vessel.
If you envision the need to stem compliant fuels for a scrubber-fitted vessel, you may define such fuels as per the configuration in the Fuel Type Setup section above.
Select appropriate H and L Fuel Types for backup:
3.5% (H) should be backed up by 0.5% (H).
0.5% (H) should be backed up by 0.1% (L) or gas oil.
If one H fuel is selected to back up another H fuel, then the backup fuel consumption rate on the vessel should be 0.00 unless the first H fuel is designated in the Fuel Zones for At Sea and In Port consumption for all appropriate zones.
On the Fuel Zones form:
Create new IMO 2020 Fuel Zone sets (must include Worldwide and Worldwide NON-ECA) to consume the designated H grade fuel on the Scrubbers tab.
Note: Selecting IMO 2020 for existing Fuel Zone sets will break backward compatibility with respect to P&L.For Vessels that will not use scrubbers in the ECA zones, configure the specific ECA Zones with appropriate L grade fuel and the consumption rate, if necessary.
Worldwide NON-ECA is now a 0.5% sulfur emission zone, and the Consumption At Sea for this zone can be set up to consume 3.5% fuel with a scrubber.
We foresee that only the North Sea and 200NM zones will remain as ECA zones, therefore in these zones, the users should select 0.1% fuel to be consumed, however, the user has an option to configure the remaining zones.
Configure vessels:
On the Vessel form, select the Scrubber the ship has installed: Open Loop, Closed Loop, or Hybrid.
On the Vessel Consumption tab, add the H grade fuel 3.5% to be consumed with the scrubber, H grade fuel 0.5% in case the scrubber is not used or not allowed, and L grade fuel 0.1% when in the ECA zone.
This section presents two scenarios that revolve around the maximum limits of 6 fuel types on a vessel:
If you can add more new compliant fuels on the vessel, they should do so in accordance with the recommendation above.
If you cannot add more new fuel types on a vessel because the vessel already has 6 fuels registered and used, the user should re-utilize the existing fuels.
Configure ports:
On the Port form, select which Supported Scrubbers are allowed in a given port. The default of the port scrubber drop-down menu is Info N/A (Information Not Available); in those cases, the system will by default calculate fuel consumption that is set up in the Fuel Zones.
