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 diagram illustrates the operation of a submarine torpedo tube. The diagram is somewhat simplified but does show the working of a submarine torpedo launch. A torpedo tube has a considerable number of interlocks for safety reasons. For example, an interlock prevents the breech door and muzzle door from opening at the same time. The submarine ...
The alternative to a moon pool in an underwater habitat is the lock-out chamber, which is essentially like a fixed submarine, maintaining internal air pressures lower than ambient sea pressure down to one atmosphere, with an airlock to enable entry and exit underwater. Underwater habitats may have connected chambers with moon pools and lock-out ...
Diagram of Jimmy Carter, showing added features USS Jimmy Carter (SSN-23) is the third and final Seawolf -class nuclear-powered fast-attack submarine in the United States Navy . Commissioned in 2005, she is named for the 39th president of the United States , Jimmy Carter , the only president to have qualified on submarines. [ 7 ]
