This timely International Conference for the utilization of Floating Structure was successfully held while having many participants from Japan and abroad. The Waterfront Real Estate Co., Ltd. initiated the core activities in cooperation with Chodai Co., Ltd. Shimizu Corporation, and the Nihon University.
    In addition to contributing to the conference as a “Gold Sponsor”, the Waterfront Real Estate Co., Ltd. and the Waterpoint Initiative set up booth in the corporate exhibition space to present own activities for Sustainable Water City Concept.

    In parallel with the International Conference, Waterfront Real Estate planned and set up a special exhibition booth by which it attracted many people from Japan and abroad. The contents of the special exhibition introduce the “Hawaii Floating City Project ‘76” and other endeavors on floating structures - pioneering projects on the marine city in the 1970s after which its concept has recently been recognized by many countries. On the second day of the conference, a briefing seminar was held here on the history of marine cities designed by the late Architect Kiyonori Kikutake who is widely recognized as a pioneer in this endeavor. Architect Shizuo Harada and Mrs. Mutsuko Kikutake Smith, widow of the architect Kiyonori Kikutake served as lecturers and disclosed many episodes relating this subject.

    Two papers were presented at the International Conference“WCFS’23 Japan”. The theme of first paper is “Sustainable Water City - A case Study in Singapore” by T. Nakajima and Y. Yamashita. The content of this paper is about the proposed floating water city in Singapore that is constructed in artificial reservoirs on land to mitigate population growth and water shortage that have been pressing issues in Singapore since 2017. The other paper is “An Innovative Design Concept of Modular Pneumatic Floating Platforms by T. Nakajima, Y. Yamashita, M. Imai and Yuuki Yamashita, which introduces the history, the proposal for Osaka Expo’25 and technical evaluation of pneumatic floating structures supported by some experimental studies.

  • September 2023
    The “Composite Pneumatic Floating Body and Wind Power Housing on this Structure” was issued as the patent on 11th September 2023 by Patent Office of Japan. Recipients of the patent are Waterfront Real Estate Co., Ltd. and Chodai Co. Ltd. Pneumatic floating bodies are floating structures that resemble an upside-down bowl. It is known that the stability of individual floating body is extremely poor. Therefore, we have conducted research and development focusing on creating a highly stable floating structure by connecting multiple pneumatic floating structures with rigid three-dimensional truss beams together with Chodai Co., Ltd. This composite pneumatic floating structure is expected to be used as an artificial ground for floating cities. It is constructed at a moderate cost and is suitable for a floating body of offshore wind power generation facilities.
