Sounds like they are operating at a loss.
At a point I can imagine that they’d need to run some cruises just to make sure everything is ship shape with equipment, procedures, and crew.
And while operating at a loss they can still write it down on the ledger.
No doubt.
If Cruise Lines don't use their ships they are operating at a loss also, and cruise ships as collateral are practically worthless now, since all the Cruise Lines are having the same problem simultaneously, and have new ships on order.
In the past many cruise ships were sold Line to Line, now only a few are sold that way, and the "scrappers" get the remainder for pennies on the dollar.

They wont be making a profit for years. They’re just getting the boats out to sea because if they stay in dock too long they become liabilities more than an asset.
