7-3 Compressed Air System Description. The compressed air system provides compressed air to five air stations in
the ROWPU space, one in the workshop, and one on stern weatherdeck. It also provides compressed air to two air
stations. for blowdown of seachests in void 2 starboard and void 4 port. These outlets, with other major components,
valves, and piping are shown schematically in Figure 7-6 for Barge 1 and in Figure 7-7 for Barges 2-and 3.
