The Bombay plan shows several layers of port and repair infrastructure around Alexandra Dock. An entrance lock controlled access, while the plan also marked Merewether Dry Dock, Hughes Dry Dock, Victoria Dock, Prince's Dock, and a careening basin. The arrangement offered more than a single repair berth: locks, basins, and dry facilities served different hull sizes and maintenance needs. The map forms another part of Britain's worldwide dockyard network. It locates India within the industrial geography that sustained imperial shipping in the Indian Ocean.
