Abstract

The pressure hull on a submarine usually consists of a long cylinder reinforced with a ring-shaped frame, so as not to fail to withstand the hydrostatic pressure load when the submarine is submerged at the depth of the ocean. This study focused on pressure-hull construction buckling strength and weight of structures using a ring stiffened compare with Swedge Stiffened structure system. Investigation of buckling strength in both types of pressure hull is done by considering the position of transverse bulkhead, frame spacing and volume of compartment. Linear buckling analysis was performed using finite element method, and the laying configuration of transverse bulkhead and frame spacing has been proposed to determine the influence of each structural configuration on buckling strength and weight of pressure hull structure.
