"In port" means Willem Sr. had not left the monitored zone when this page was built. 2 of these 10 calls were recorded before the exit time could be verified, so the arrival is shown but the time at anchor and at berth is left blank rather than estimated. Verified durations start 18 September 2026.

How this data is collected

Positions come from public AIS transponder broadcasts, matched against PortInsight's monitored port and anchorage polygons. Port calls and time at anchorage are derived from those observations, not from carrier schedules, so they reflect where the vessel actually was.
