There are a bunch that sit pier side. The high speed vessels are always in port to minimize the aluminum hulls cracking when they are underway.
The oilers are so wasted and past their service life that many don’t move much. Leaking shafts, thinning plates/ruptures, broken king posts, leaking cargo oil pipes. Many are being kept afloat while waiting to be retired.
The special mission ships don’t move much. Hospital ships are in endless repair. Salvage/tugs just wait for work. Tenders just sit in Guam or in a yard.
It’s only the fourteen AKEs, the two AOEs and a handful of AOs that work. MSC is fast becoming a paper fleet manned by vacancies.
