Could tenders set up at a location and become a maintenance hub for many kinds of machinery?
Short answerYes; their workshops and staff often supplied the effective maintenance capacity behind a wartime port.
NotesTenders could establish workshops for many kinds of machinery at a chosen location. Some wartime ports depended heavily on these ships for their actual repair capacity. At Alexandria early in the war, tenders performed much of the work involved in maintaining ships and their components. The port's facilities therefore included the equipment and personnel afloat alongside its shore establishment.
