AUTOMATED OPTIMAL DESIGN OF FRAMREINFORCED, SUBMERSIBLE, CIRCULAR, CYLINDRICAL SHELLS

The Direct Search Design Algorithm and the Golden Search are utilized to produce an automated optimal dimensional synthesis procedure for the structural design of submersible, frame reinforced, circular shells. Using this procedure it was found that the shell weight/weight displaced ratio is independent of the diameter of the shell and the optimal shell dimensions are proportional to the diameter. Between frame shell buckling is generally the most important instability failure mode in optimal designs. Where significant out-of-roundness (eccentricity) of the shell exists, frame yield normally also controls the design. High-strength steels were found to be effective primarily by reducing the adverse effect of eccentricity and by controlling plating yield for shells under relatively high pressure.
