Mega Floating City "Green Float"; Concept and technology

Masaki Takeuchi & Ikuo Yoshida

The world is currently facing the sea level rise due to climate change. And we are facing many sorts of problems of energy, water, food, garbage, air pollution and so on. Fortunately, however, 70% of the earth’s surface is covered with the ocean. The ocean has a tremendous capacity and a big influence on the global environment and the sustainability of human beings.  We Shimizu are heading new challenges for the better future utilizing the potential of the ocean. “Green Float” is a new model for eco friendly Mega Floating City. The Green Float concept embodies two areas of innovation. The one is “Green innovation” and the other is “Float innovation”. By integrating “Green Innovation” and “Float Innovation”, a super high value-added Mega Floating City can be realized. In order to perform a basic verification of the technology, several hydraulic float model experiments and numerical computations about wind waves and tsunamis were conducted. We got a public third party's certification concerning about “structural safety of floating building”. In addition, we continue to research and development the "City Grid System (city Cell, Module, Unit) of mega float city" based on Green Float.
