Pressure hulls are designed to stand the hydro static and dynamic bearing when they operate under water. These structures are also applied to naval submarines, remotely operated vehicle (ROV) and autonomous underwater vehicles (AUV). The underwater vehicle plays an important role in the petroleum industry, ocean engineering, and fishing, etc. To do so, ROV and AUV are studied for design and fabrication. This paper focuses on studying linear and nonlinear buckling analysis of stiffened cylindrical pressure hull under bearing load in Vietnam sea environment. The modeling of this pressure hull structure has been carried out by finite element analysis software packages.
