Why Britain avoided a Second World War repair-yard shortage

Did the Royal Navy suffer a shortage of repair yards in the Second World War, and could closed docks be reopened?

Not generally: most docks remained in use, and valuable repair facilities usually found new owners even when shipbuilding firms failed.

The Royal Navy did not suffer a severe general shortage of repair yards during the Second World War because most of the relevant facilities remained open. Shipbuilding companies could fail, but a useful dry dock rarely became valueless. New owners had strong reasons to buy and operate the physical infrastructure even when the original firm disappeared. That transfer of ownership preserved repair capacity through the war. Corporate failure did not necessarily remove a strategically useful waterfront asset.
