Toyo Construction puts safe works using dynamic response analysis of floating body into practical application.

TOYO CONSTRUCTION CO., LTD. (Kyoji Takezawa, Representative Director, President) has developed a
system for safe works by using numerical simulation technique for dynamic response of floating body at
offshore works, and has put the system into practical application.

 

For numerical analysis of the degree of dynamic response of floating body, the Three-dimensional coupled
fluid-structure-sediment-seabed model (FS3M) developed by Nagoya University (Norimi Mizutani, Professor
and Tomoaki Nakamura, Associate professor) is utilized.
This system models a towed caisson or crane ship as a floating body and numerically simulates dynamic
response caused by ocean wave, which will enable to quantitatively grasp the extent to which the caisson or
crane ship will react attacked by the ocean wave and consequently enable to set up countermeasures for
mitigating the impact and define a criterion for suspending work against expected ocean waves.
The Company has implemented safe construction practices by utilizing this system in construction works of
breakwater, including a construction work of breakwater for Kuji Port district (North bank) in Iwate prefecture.
We will, in the future, improve skills for safe and efficient construction technologies and contribute to safe &
secure and sustainable society with support of decision-making process for appropriateness of construction by
integrating the database built through advanced numerical simulation and the empirical value obtained through
various construction achievements.
