「The Company therefore developed the "motion-reduction tank method" to reduce caisson motion. It is particularly effective when wave periods resonate with caisson motion, and is expected to halve the motion.」
For reducing the motion of floating caissons, the technology at the demonstration stage was developed as the motion-reduction tank method, with an expected halving of motion and improvements in safety and productivity. - FY2023First statedAnnual report
「Under the conditions tested, the Company confirmed an approximately 30% reduction in motion. This demonstrated that motion can be reduced in actual marine environments by using a motion-reduction tank with a full-scale caisson.」
An approximately 30% reduction in motion was confirmed in an in-situ marine test using a full-scale caisson, and the Company is pursuing field implementation through lower fabrication costs and shorter construction times.
