Owner, operator and manager changes found by comparing yearly EU MRV reports are dated to the reporting year ("during 2025"), not to a day. Port calls here are the most recent only; the full lists are further down.

Former and other names

A sanctions list's date is the earliest date the list shows the name, not when the ship took it. A name on a list is shown as a former name only where AIS shows the ship using another name after that date; otherwise it is listed as a name the list uses. AIS name changes are dated when Voydar saw them.
