Additional Fields: Start and End Dates

From release 8.6, optional Start Date and End Dates have been added to restricted areas. This ensures that when planning a voyage, you have a clear overview of which zones are active and how they impact fuel consumption and compliance requirements.

How Start and End Dates Affect Restricted Areas

When a vessel crosses an ECA (Emission Control Area)/OLRA (Open Loop Restricted Area) boundary or calls at a port within a restricted area, the Start and End Dates determine when the restricted area rules apply. This ensures regulatory compliance and helps with voyage planning by clearly defining when specific restrictions are in effect.

Restricted Area Rules (At Sea)

If a route crosses a restricted area zone, the restricted area rules apply based on the arrival date at the next port:

• If both Start and End Dates are provided, the restricted area rules apply only if the arrival date falls within the date range.

• If only a Start Date is provided, the restricted area rules apply if the arrival date is after the Start Date.

• If only an End Date is provided, the restricted area rules apply if the arrival date is before the End Date.

• If no dates are provided, the restricted area rules apply for the entire route.

Restricted Area Rules (In Port)

When calculating fuel usage in port, the allowed bunker category is determined as follows:

• If the vessel has any allowed bunker categories, the highest-priority one permitted in the restricted area is used.

• If the vessel has no allowed bunker categories, the highest-priority bunker category in the restricted area is used.

• If the port is NOT within an ECA/OLRA zone:

  • If vessel is scrubber fitted:

    • The highest-priority bunker category on the vessel is used if available.

    • Otherwise, the highest-priority bunker from master data is used.

  • Otherwise:

    • The highest-priority vessel bunker category permitted in the port is used.

Voyage Map Updates

A new filter, "Active Areas," has been added to display only restricted areas with active Start and End Dates. This filter is enabled by default and is voyage specific. When selected, the map will only show the areas where restrictions are currently in effect for the current voyage. This can be seen in the figures below.
