neo RiSe® Land-Mounted Flag-Gate Type Seawall Wins Osaka Superior Invention Award
Jan 29, 2019
The land-mounted flap-gate type seawall (product name: neo RiSe®) developed by Hitachi Zosen Corporation and that uses the force of buoyancy during a flood to operate automatically without a power source or human operation has been awarded with the 2018 Osaka Superior Invention Award given by the Osaka Institute of Invention and Innovation.
The Osaka Superior Invention Awards are given out to recognize particularly superior inventions from Osaka by the Osaka Institute of Invention and Innovation to work for the revitalization of Osaka and the development of science and technology, as well as to encourage inventions. This award for the neo RiSe® (No energy, No operation, Rising seawall) is a recognition of its system (invention) for operating without power sources or human input and its numerous examples of use. Hitachi Zosen will use the receipt of this award to further spread this technology, construct a sustainable disaster-proofing or disaster-mitigating society, and also to help achieve the SDGs (Sustainable Development Goals) through this project.
Features of neo RiSe®
In the Great East Japan Earthquake of March 2011, a large number of firemen lost their lives as they worked to raise sea gates at ports. This is one of the biggest issues considered when planning future disaster relief or mitigation measures. The neo RiSe® is a tsunami/storm surge disaster prevention system that could solve this issue.
The system is noted for its use of the power of water during a tsunami, storm surge, flood, or similar to operate. It is able to respond to sudden incidents such as tsunamis from earthquakes, can operate without electricity, and will not operate incorrectly. In addition, as the start of the flood is the trigger for operation, it will not prevent people or vehicles from escaping immediately before inundation.
Use of neo RiSe®
Since the first order in 2014, the land-mounted neo RiSe® has been installed in around a hundred locations, including the entrance to the seawall for the the MLIT Shikoku Regional Development Bureau. In 2017, we received our first order for the sea-mounted flap-gate type water gate. We hope to continue to contribute to the formation of a society that is able to easily overcome disasters, offering safety and peace of mind, through our neo RiSe® series.
