Özet

Through three main renewable energy sources to be in service, the architectural design and structural design due to the architectural design of the floating modular energy island (FMEI) should be considered very carefully to get a more functional, feasible and economic outcome for the investment. In the paper, the structural system of wind turbine, photovoltaic structure and wave energy converters will be examined through their architectural and structural design strategies. For wind turbines, the advantages of the diagrid system for the tower, without cladding, will be defined to let the wind flow through the openings, not to get high pressure for the wind tower to let it easily stand up against hard winds. Same as the wind tower's diagrid structural design, also the floating foundation system can be designed by the diagrid system to let the waves flow through the foundation not to get more pressure to make the platform, floating energy island, swim in comfort mood and also to let the wave energy converters be built more strongly over the diagrid structural system of the floating foundations. For photovoltaic structure, the system how the photovoltaic panels could be mounted mainly over the diagrid structure for the wind turbine as how they could be mounted over the body of boats as catamarans, and also over the sails of the sailing boats, etc. as a kind of montage over a floating body. And also in the paper, the geometric form of the floating modular energy island will be discussed as if it would be a triangle, a square, a circle, a rectangular, a L-shape, a hexagon, and an octagonal, etc. in plan, together with the height of the service spaces over and under the platform, with the advantages of all shapes and also their combination with each other through their modular features. The most important part of this proposal as a floating modular energy island is, three in one as wind, solar and wave are at the same platform. This paper explores how the integration of three main renewable energy sources-wind, solar, and wave- can be optimized in the design of a Floating Modular Energy Island(FMEI) to serve as a multifunctional floating port city. Emphasis is placed on how architectural and structural solutions, such as the use of diagrid systems and modular layouts, can enhance the platform's functionality, technical feasibility, and economic sustainability. The diagrid system is discussed as a reference for both wind tower structures and floating foundations, supporting the combined generation of wind, solar, and wave energy. This paper also examines spatial planning principles, environmental integration, and circular economy strategies to position FMEIs resilient and adaptable offshore urban infrastructures.
