blowdown of seachest In void 4 port. Used In conjunction with
Valve
seawater valve SW44.
Airhose, 50 Feet
Attached to air stations. Provides air pressure from air stations
Self-Retracting
to pneumatic equipment.
Airhose, 25 Feet
Dedicated hose used only for providing air pressure to
Self-Retracting
drive PIG through shore discharge hose.
Seawater Valve SW30*
Workshop port bulkhead. Used with seawater seachest blowdown valve to
blowdown seachest in void 2 port. When opened, this valve vents forward
seachest to atmosphere through venting pipe to deckhouse top. When closed,
valve forces air from air station into seachest for blowdown.
