Research on Calculation and Criteria of Strength and Stability of Submersible Cylindrical Shell

The standards of strength and stability of submersibles and its calculation methods based on the domestic submersible rules and ABS＇s are compared. The difference of two calculation methods and reasons behind are analyzed. The differences of the criteria for stability and strength of the rules between two countries and the factors that influence on the safety of submersible cylindrical shell are analyzed. The calculation examples of the proven reliability are given.
