The Ministry of Land, Infrastructure, Transport and Tourism (MLIT) aims to perform underwater inspection of dams using vehicles instead of divers, to address the deterioration of infrastructures, considering the shortage of engineers and technicians in the near future, in order to improve inspection safety. To this end, the technology for underwater inspection vehicles was publicly invited to conduct the verification of the technology at the concrete gravity dams and concrete arch dams, managed by MLIT. This paper reports the contents of the field verification, evaluation of the technology, and the results of the trial introduction, assuming practical operation.
