Abstract

PURPOSE:To improve stability of the hull as well as to increase stability to lists of the hull in such a way that the outer hull is made into a double structure to form plurally comparted air-tight air chambers by which buoyancy is given to the hull. CONSTITUTION:A double structure is made by forming it by hull bulkheads 5 made of the inner steel plates and by a outer hull 6 which is made of the similar steel plates, the structural space is divided into a multitude of air chambers 8 by a plurality of longitudinal partitions 7, and holes 9 which gives free access of sea water are provided at the lower portions of the air chambers 8. Since it is structured such as this, during navigation, in case where the ship is listed by rolling, etc., sea water is further flowed into the air chambers 8 on the side involved in the list by submerging water pressure, air in the air chambers 8 is further compressed, buoyancy is increased higher up, while sea water inside is flowed out by lift in the air chambers 8 on the opposite side, and it leads to the decompressed condition, so that absorptive power is produced, and in result, stability to the list of the ship can be improved.
