Construction and preservation of resilient submarine infrastructure

The demands for industrial use of resources and observational data on earthquakes and tsunamis are increasing. Accordingly, technological development for underwater infrastructure and disaster prevention in the submarine system has become an urgent topic of interest.
For expanding resilient infrastructure in submarine zones, we must develop advanced technology to 1) estimate the ground stability because of the construction load, 2) install structures in a safe and well-arranged manner, and 3) manage them to submarine hazards over the long term. Currently, we are trying to simultaneously evaluate the diversified problems among submarine ground-structure-ocean systems and develop installation methods for marine infrastructure with universities and other research institutes based on research vessels, observational techniques, and mathematical resources at JAMSTEC.
Our research will contribute to Goal 9: Construct resilient infrastructure, promote inclusive and sustainable industrialization and innovation (particularly contributing to targets 9.1 and 9.5).
