Olympia can be repaired if preservation skills are rebuilt

Do any dry docks still have the expertise to work on museum ships such as USS Olympia?

Yes, although skills would need rebuilding and some repairs might use welded construction disguised to resemble the original riveting.

Suitable dry docks could undertake work on Olympia. Some specialized skills would have to be rebuilt because the ship belongs to an older construction tradition. Modern repairs could use welding while reproducing the appearance of riveted work where necessary. The limiting problem is therefore preservation capacity and expertise rather than a complete absence of repair options.
