Most likely that in the near future we'll have this ship autonomously travel around Erangel docks, like the Vikendi train travels across the winter location.
This assumption was made by the datamainer PlayerIGN, referring to various hints from the developers themselves over the past few weeks, as well as the name of the picture from the description of the patch 8.2 ("Erangel Ferry"), which shows the docks.
