Veson Nautical has enhanced the existing Fuel Zone configuration and fuel consumption functionality to help our clients comply with the IMO 2020 bunker regulations. The new IMO 2020 functionality accommodates the use of scrubbers on vessels and accounts for the allowance of scrubbers in given ports and zones. By designating the Fuel Types for 3.5%, 0.5%, and 0.1% sulfur and the global areas in which they should be consumed, clients are able to accurately project bunker consumption on estimates and voyages.

Vessels/Fleets with Scrubber-Fitted Vessels

...

The below recommendations outline configurations based on commonly used existing setups. However, the delivered features described above offer significant flexibility and can accommodate a wide range of setups.

GENERAL ASSUMPTIONS:

There are 3 fuel types:

1. 3.5% (only scrubber fitted vessels will have this onboard)
2. 0.5% (the new high sulfur fuel)
3. 0.1% (the new low sulfur fuel)

ASSUMPTIONS FOR SCRUBBER-ENABLED VESSELS:

• Scrubbers with 0.5% output:
  • In areas where 0.1% is required, vessel will either burn LSG 0.1% or ultra-low fuel oil 0.1%
  • In areas where port restrict open loop, vessel will either burn LSG 0.1% or ultra-low fuel oil 0.1%
  • Scrubbers with 0.1% output:
  • In areas where port restrict open loop, vessel will either burn LSG 0.1% or ultra-low fuel oil 0.1%

VESSELS OR FLEETS BURNING COMPLIANT FUEL ONLY (VESSELS WITHOUT SCRUBBERS)

1. Fuel Types & Fuel Zones
   1. In the Data Center ➔ Fuel/Lube Types either:
      1. Add new Types for compliant fuel and set 0.5% to H and 0.1% to L, and designate all noncompliant Types as H, including the noncompliant fuel to be used with scrubbers.
      2. Designate existing Type(s) as compliant (L) and noncompliant (H).
      3. Select appropriate H and L Fuel Types for backup.
      On the Fuel Zones form:
      1. Configure each zone, include Worldwide, , OR
      2. Re-use existing fuel types, for example: designate current ‘H’ as compliant 0.5%, and current ‘L’ as 0.1%.
2. Select appropriate compliant 0.5 % H backup of 3.5% H, and 0.1% or LSG as a backup for 0.5%.
   1. During the period as your fleet transitions from non-compliant to compliant fuel consumption, compliant fuel can be set at the backup fuel for non-compliant fuel, with the consumption rate set to 0.00.
3. Vessel Setup
   1. In the Data Center ➔ Vessel ➔ Consumption, add the H and L grade fuels, unless the past fuel types will be re-used.

FLEETS WITH SCRUBBER-FITTED VESSELS

1. Define Compliant and High-Sulfur Fuels
   1. 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.
   2. 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 Compliant Fuel section above. In the Data Center ➔ Fuel/Lube Types.
   3. Select appropriate H and L Fuel Types for backup
      1. 3.5% (H) should be backed up by 0.5% (H).
      2. 0.5% (H) should be backed up by 0.1% (L) or gas oil.
      3. 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.
   4. In the Data Center ➔ Fuel Zones:
   5. On the Vessel Consumption tab,
      1. Configure each zone (must include Worldwide and Worldwide NON-ECA) to consume the designated H grade fuel with the suffix +Sin the “Scrubbers” tab.
      2. For vessels 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.
   Configure vessels.
   1. 1. Worldwide NON-ECA is now a 0.5% sulfur emission zone, and the Consumption At Sea for this zone can be setup to consume 3.5% fuel with a scrubber.
      2. We foresee that only 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.
2. Configure Vessels
   1. In the Data Center ➔ Vessel ➔ Settings select the Scrubber Type the ship has installed: open loop, closed loop, or hybrid.
   2. In the Data Center ➔ Vessel ➔ Consumption add the H grade fuel 3.5% to be consumed with the scrubber, and L H grade fuel 0.5% in case the scrubber is not used or not allowed
   3. On the Vessel form, select which Scrubber the ship has installed: Open Loop, Closed Loop, or Hybrid.
   Configure ports.
   1. On the Port Properties panel, select which Supported Scrubbers are , and L grade fuel 0.1% when in ECA zone.
      1. This section presents two scenarios that revolve around the maximum limits of 6 fuel types on a vessel:
         1. If the user is able to add more new compliant fuels on the vessel, they should do so in accordance to the recommendation above.
         2. If the user is unable to add more new fuel types on a vessel because vessel already has 6 fuels registered and used, the user should re-utilize the existing fuels.
3. Configure Ports
   1. In the Data Center ➔ Port, select which type of scrubber is allowed in a given port. By default, The default of the port scrubber dropdown is Info N/A is selected(Information Not Available), in which case those cases the system will by default calculate fuel consumption that is set up in the Fuel Zones.

Vessels/Fleets Burning Compliant Fuel Only

1. Define Fuel Types and Fuel Zones.
   1. On the Fuel/Lube Types form
      1. Do one of the following:
         
         • Add new Types for compliant fuel and set to L, and designate all noncompliant Types as H.
         • Designate an existing Type(s) as compliant (L) and noncompliant (H).
      2. Select appropriate H and L Fuel Types for backup.
   2. On the Fuel Zones form:
      1. Designate which H grade fuel will be consumed in the Worldwide zone.
      2. Configure the ECA Zones to consume L grade fuels.
2. Configure vessels.
   1. On the Vessel Consumption tab, add the H and L grade fuels, unless the past fuel types will be reused.
