SIV II Digital twin with fiber optic sensors - Hideaki Murayama

Hideaki Murayama, The University of Tokyo Biography Hideaki Murayama received the B.E., M.E., and Dr.Eng. degrees in electronic engineering from the University of Tokyo (UTokyo), Tokyo, Japan, in 1996, 1998, and 2001, respectively. He has applied fiber sensors to structural health monitoring (SHM) or digital twin of ships and lightweight structures. He joined the National Space Development Agency of Japan as a Research Fellow in 2001 and moved to UTokyo in 2003 as a Lecturer. He has been a Professor with the Department of Ocean Technology, Policy, and Environment since 2017. He is studying on fiber optic sensor networks, diagnosis/prognosis techniques based on inverse analysis or artificial intelligence, and lightweight materials/structures made from carbon fibers applied not only to offshore structures and marine vessels but also to aircrafts, space vehicles, infrastructures, and robots. He is an Expert Member of IEC SC86C/WG2 on fiber optic sensors and chairing the mirror committee of Japan. Prof. Murayama has regularly participated in OFS since 2003 (OFS-16) and has been a Technical Program Committee (TPC) Member since 2012 (OFS-22). He was with the OFS-28 as a TPC Chair. Digital twin with fiber-optic sensors The concepts and technologies of digital twin/health monitoring, providing overall displacement and stress, can enhance the reliability and safety of structures. The displacement can be reconstructed by integration or inverse analysis based on strains measured at multiple points by using distributed fiber-optic sensors and stress can be calculated based on the displacement and strain distributions. In this presentation, the development of digital twins for ship structures with fiber-optic sensors is shown. In addition, the applications of shape sensing technology to structural health monitoring of linear structures that play an important role in offshore structures, as cables for risers or unmanned submersibles, mooring cables and so on, will be shown.
