abstract = {The concept of Modular Floating Structures (MFS) offers a unique avenue to explore new and sustainable ways for addressing issues of coastal urbanization and sea level rise in the proximity of coastal cities. This concept is easily implemented in calm waters without the interference of waves. Yet, its implementation in open water, poses greater challenges, particularly in terms of habitability and comfort. The current study examines the feasibility of the concept in two locations: in mild sea zone near Singapore and in open water conditions at the Eastern Mediterranean Sea. Both conditions are examined in operational and extreme storms. It is shown that the MFS configuration can attenuate incident waves of short periods. This reduces the motion amplitudes of the inner modules with respect to the exterior modules facing the waves. It is also presented that during extreme storms, the chosen configuration is less effective, and the motion amplitudes of all modules within the MFS fabric are almost identical. To further increase the acceptable sea states, the study proposes a unique floating seawall design, which provides a substantial wave reduction in long wave periods. The study presents the efficiency of the new configuration in operational weather and a 100-years storm.},
