Are they drifting into/in sea lanes?
My memory is trying to tell me that in times past ships that were abandoned/could not navigate and were presenting a hazzard to navigation were hauled out of the way. Sometimes left to float away from sea lanes, but usually wither beached or berthed with the country doing so claiming salvage on flotsam. Admiralty Court hearing to ratify possession, the repurpose/scrap.
Apparently this ship is not insured, as nobody seems to be wanting to protect their financial interest in it.
Let the US Navy claim salvage, the tow it off Iran and conduct naval gunnery practice. Maybe invite a few other nations to join in?
stay safe.
