Thanks.

From that article:

‘The Antarctic research base Druzhnaya I, which was originally established on the Filchner–Ronne Ice Shelf, was situated on the iceberg when it calved.[2] Subsequently, a rescue mission was started in 1987 and ultimately moved/renamed the base to Druzhnaya III.’

That made me wonder about their naming system.

I and II existed, I floated away and was saved and moved, becoming III. IV was then built. https://en.wikipedia.org/wiki/Druzhnaya_Station
