FleetLeaks tracks terminals and operational zones to show where vessels stage, anchor, load, discharge, or cluster offshore. Terminal zones also support filtering and event tagging.

What a terminal means on FleetLeaks
A terminal page can represent a facility, an offshore structure, or an operational area where activity repeats over time. The page context clarifies the type.
Zones and geofences
Why zones exist
- Filter vessel positions by area.
- Tag AIS events with meaningful location context.
- Aggregate activity trends over time.
How zones are defined
- Published terminal coordinates and local references.
- Public maps and OSINT research.
- Observed staging patterns once a zone repeats.
How activity is interpreted
Zone presence
A vessel inside a zone means the vessel was present in that defined area during the timeframe, based on AIS positions. This supports filtering and pattern analysis.
Limitations
- AIS coverage varies by region.
- Zones are approximations.
- Destination fields can be misleading.
- Operational activity can occur outside the boundary.
How terminals connect to other systems
Terminal zones connect to vessel records and AIS events. Event pages can display zone tags and evidence trails tied to a location.
