SHIP HAVING SINKING PREVENTION APPARATUS

The present invention relates to a ship having a submergence preventing device. According to the present invention, a submergence preventing device comprises: a plurality of tubes separately installed in the lateral surfaces, and a ship′s stern to provide buoyancy to the submerged portions of the ship when the ship is submerged; a gas tank to supply gas to the plurality of tubes; a plurality of dampers installed in pipes to connect the gas tank and each tube to control the amount of the gas supplied from the gas tank to each tube; a plurality of submergence detecting units installed to be matched with the tubes one by one to detect the ship′s submergence; and a control part to control the amount of the gas supplied from the gas tank to each tube by controlling the opening degree of each damper in accordance to a submergence detecting information transmitted from the submergence detecting units.
