    There is a growing interest in providing a comfortable environment for crew members aboard ships. As a result, the International Organization for Standardization (ISO) and the Korea Register, an organization that evaluates ship classifications, have established regulations presenting vibration acceptance criteria, which are continuously revised. To meet these vibration acceptance standards, shipbuilding companies are consistently investing in research and development, to ensure that newly constructed ships operate without issues. In this study, an optimal design investigation was conducted from the perspective of avoiding resonance to identify areas where excessive vibration is expected during the early design phase of ship construction. In this phase, the resonance of the main excitation sources and the hull structure were evaluated, to determine whether the vibration response levels meet the acceptance criteria. Structural optimization was performed to reduce vibration in areas prone to excessive vibration using the optimization module of MSC.Nastran, a commercial software, and the results were compared.
