ABSTRACT:
The invention pertains to apparatus for preventing the flooding of an enclosed plenum chamber pressurized by a source of pressurized gas provided through a duct system leading from a plenum chamber open to the surface of the water over which the ship rides. The inlet to the duct system located within the open plenum chamber is formed to reject by deflection a substantial quantity of water adjacent the inlet from entry. Any small amount of water entering the duct that is not initially rejected from the inlet is ramped through the duct and collected in a stern holding tank. The holding tanks include a float controlled water exhaust valve that opens to the atmosphere and exhausts that collected water therein with the aid of plenum pressure. Any water reaching the closed plenum chamber is constantly exhausted therefrom through apertures in its walls. An additional embodiment is disclosed that prevents substantially all water from entering the enclosed plenum chamber.
