“Most of these ships are pre-loaded with equipment and supplies.”
You’re talking about pre-positioned ships. These aren’t those. These stay in port (I know around Orange, Tx., possibly other places). Several of them are going through their 5 year yard availability. I know this because I can look out my office window and see three of them, one in our shipyard and two in another shipyard close by. Two of the three are on drydocks.
