Optimized design and structural analysis of a non-pressurized manned submersible
… further optimize the hull weldment and variable ballast tanks. When three different designs were subsequently evaluated to verify the parametric model and the scalability of the NPMS design concept, all three were found to be able to be successfully generated and to meet the stated design …
