Port calls

Two kinds of evidence, kept apart: calls Voydar detected from the ship's AIS positions, and arrivals and departures published by port authorities and customs records.

Detected from AIS AIS-detected

Kisarazu JPKZU	Sep 28, 2026, 18:41 UTC	Sep 29, 2026, 23:34 UTC	28 h 53 min

Detected by Voydar when the ship's AIS positions stayed slow inside a harbour area. Calls shorter than 30 minutes are not shown. Depends on AIS reception; detection started on June 8, 2026.
