Abstract

This research proposal seeks to perform an experimental validation of the innovative Topology Optimization (TO) framework developed for the design of 3D plate reinforcements in submersible and semi-submersible structures, with an emphasis on stability constraints. The developed framework aims to integrate self-weight TO techniques and hydrostatic pressure loads. The experimental results are compared with the real-world performance of the ships, pontoons, and submarines, thereby confirming the feasibility and reliability of optimized designs. Under the structural experimental analysis concerning hydrostatic loads, some are highlighted, such as the flexible backbone, flexible joint model, and elastic (fully elastic) model. This research project aspires to provide valuable contributions to structural optimization techniques, enhancing the design and performance of floating structures, and supporting the economic and sustainable growth of the marine industry. This project foresees a collaboration with TU Delft to learning the techniques necessary to perform the experimental analysis. Through this collaboration, we anticipate making significant contributions to the field of ship and submarine structures by developing highly competitive and innovative design and experimental tools.
