Abstract |
Interest in modular floating structures is growing as a solution for efficient utilization of ocean spaces. Modular floating structures are formed by arranging individual modules into a single structure, so careful consideration of the arrangement is necessary in the initial design phase. This study investigates the influence of modular arrangement (orientation, gap, and the number of modules) on the dynamic response of modular floating structures installed in coastal areas. The Jonswap spectrum, which appropriately represents the characteristics of coastal environments, was applied, and numerical analysis focused on the vertical acceleration at the corners of each module. The arrangement analyzed ranged from 1×2 to 1×6 modules, and the connections between the modules were considered as hinged joints. The results showed that the maximum response occurred at a heading angle of 0°, with the highest response at the module first exposed to the waves. Additionally, the response remained relatively unchanged beyond a certain gap, with a significant reduction in response after the first module. This highlights the importance of focusing on vibration control for the first module. These findings provide essential reference data for optimizing the layout strategies in the design of modular floating structures. |
