The vents of the Redoutable are under the casing. The square openings in the casing are limber holes to facilitate draining the superstructure. In submarine technology a vent is a valve fitted to the top of a submarine's ballast tanks to let air escape from the top of the ballast tank and be replaced by water entering through the opening(s) called "flood ports" or "floods" at the bottom of the ...
This Kingston valve, controllable both manually and hydraulically, is known by some as main vent operating gear. Main ballast tanks are in pairs, one on each side of the boat. One Kingston valve serves a pair, but each tank has a vent riser, with air connections and stop valves in the vent riser. The tank bottom is open to the sea through flood ...
Subsea valves are used to isolate or control the flow of material through an undersea pipeline (submarine pipeline) or other apparatus.Most commonly used to transport oil and gas, they are designed to function in a sub-marine environment, withstanding the effects of raised external pressure, salt-water corrosion, and bubbles or debris in the material carried.

Submarine escape trunk View inside a submarine escape trunk, looking up from below the lower hatch. An escape trunk is a small compartment on a submarine which provides a means for crew to escape from a downed submarine; it operates on a principle similar to an airlock, in that it allows the transfer of persons or objects between two areas of different pressure.
The interhull space is used for some of the equipment which can tolerate the high external pressure at maximum depth and exposure to the water. This equipment significantly differs between submarines, and generally includes various water and air tanks. In a single-hull submarine, the light hull is discontinuous and exists mainly at the bow and ...
