the.com/ghost ship

A vessel still sailing, crewless, because the paperwork never told it to stop.

means A ship found adrift or washed ashore with no living crew aboard, its fate unexplained — or more loosely, any vessel, project, or account that keeps running on autopilot long after everyone has abandoned it.

from The literal sense is old maritime lore — sailors' tales of vessels like the legendary Flying Dutchman, doomed to sail forever, plus real documented cases of ships (the Mary Celeste being the most famous) discovered intact and moving but utterly empty, crew vanished without explanation. 'Ghost' here works exactly as it does elsewhere in English — something that persists in appearance after the life or purpose behind it is gone. The extended use, for abandoned accounts, servers, or shell companies still technically 'running,' is a natural 20th/21st-century metaphor riding on that older image, not a separate coinage.
