The Raijin Float® platform is made up of prefabricated concrete components that are assembled on site. The components are designed to be modular, which allows for rapid construction and assembly of the platform. The platform's stability is achieved through a combination of its shape and its use of prestressed concrete, which provides added strength and durability.

Prestressed concrete is a type of concrete that is reinforced with tensioned steel cables or rods. This technique allows for the creation of concrete structures that are stronger and more resistant to bending and cracking than traditional reinforced concrete structures. The use of prestressed concrete can help to reduce the weight and volume of the platform, while maintaining its strength and stability.

Overall, the use of precast and prestressed concrete in floating wind turbine platforms can offer several advantages, including improved durability, reduced weight, and faster construction times.
