General AssumptionsThere are 3 fuel types: - 3.5% (only scrubber-fitted vessels will have this onboard)
- 0.5% (the new high-sulfur fuel)
- 0.1% (the new low-sulfur fuel)
Assumptions for Scrubber-Enabled VesselsFor scrubbers with 0.5% output: - In areas where 0.1% is required, the vessel will either burn LSG 0.1% or ultra-low fuel oil 0.1%
- In areas where the port restricts Open Loop scrubbers, the vessel will either burn LSG 0.1% or ultra-low fuel oil 0.1%
- Scrubbers with 0.1% output:
- In areas where the port restricts Open Loop scrubbers, the vessel will either burn LSG 0.1% or ultra-low fuel oil 0.1%
Vessels or Fleets Burning Compliant Fuel Only (Vessels without Scrubbers)- Fuel Types and Fuel Zones
- On the Fuel/Lube Types form, either:
- Add new Types for compliant fuel and set 0.5% to H and 0.1% to L.
- Reuse existing fuel types, for example: designate the current H as compliant 0.5%, and the current L as 0.1%.
- Select appropriate compliant 0.5 % H backup of 3.5% H, and 0.1% or LSG as a backup for 0.5%.
- During the period as your fleet transitions from noncompliant to compliant fuel consumption, compliant fuel can be set at the backup fuel for noncompliant fuel, with the consumption rate set to 0.00.
- Vessel Setup
- On the Vessel Consumption tab, add the H and L grade fuels, unless the past fuel types will be reused.
Fleets with Scrubber-Fitted Vessels- 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 VIP - Compliance with IMO 2020 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. Warning |
---|
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.
Debunkering Best PracticesIf needed, you can debunker a lifted quantity or transfer bunker quantities between two types. On the Bunker Liftings form, enter a negative lifted quantity. On the Bunker Lifting Selection form, select the FIFO lot to remove the quantity from; it does not have to be the last lot. The FIFO queue is modified. The price for the negative quantity is defined by the invoice price.
