One kind of spherical pressure gas tank for ship is designed. The finite element model is built by software Ansys. According to the stress distribution in the finite element model, three dangerous sections are selected and analyzed carefully, and the results are evaluated. Finally, the alternating stress intensity is obtained by using a load step analysis method of software Ansys, and the fatigue property of the gas tank is analyzed.
