HMS Belfast illustrates the long maintenance cycle behind a preserved warship. Crews can complete a great deal of work while the ship remains in the Thames, but the underwater hull cannot stay immersed indefinitely without full inspection and repair. Belfast had last been dry-docked in 1999 after a previous docking in 1982, so the 2021 discussion already treated another docking as an approaching requirement. Finding a dock with enough space and paying for the work are part of preservation rather than optional cosmetic improvements. The example shows why visitor support and long-range infrastructure planning matter to the survival of museum ships.

Why museum warships still need dry-docking
Permanent mooring does not remove underwater maintenance: even a museum ship in fresh water eventually needs inspection and work in a suitable dock.
