Validation of the practical utility of a remote-controlled boat system for port structure inspection and diagnosis
First written in FY2017. 7 of 7 entries say "Advanced", first in FY2017. Latest entry: FY2026.
The whole theme swung hardest in 2021: 1 of 10 companies on the "Worse" side.
15 other companies' latest entry also says "Advanced".

「Compared with manual work using conventional inspection hammers, labor requirements can be reduced to approximately 1/5 to 1/10 at most because temporary scaffolding is not required.」
The initiative progressed from pier surveys and AI-based diagnoses using i-Boat to the development and commercialization of an impact-sound inspection system using a spherical projectile launching and retrieval device, which received a Special Award from the Ministry of Land, Infrastructure, Transport and Tourism. - FY2023AdvancedAnnual report
「The company also developed technology that uses AI to assess the residual load-bearing capacity of piers based on inspection and diagnosis results. The technology predicts how piers will be damaged by earthquakes and deterioration over time. During the consolidated fiscal year, the technology received the Award for Excellence in the National Institute for Land and Infrastructure Management Technology Development Award.」
The initiative progressed from surveys and diagnoses using i-Boat to AI-based technology for assessing residual load-bearing capacity, and the technology received the Award for Excellence in the National Institute for Land and Infrastructure Management Technology Development Award. - FY2022AdvancedAnnual report
「The company also developed technology that uses AI to assess the residual load-bearing capacity of piers based on inspection and diagnosis results.」
The initiative progressed from pier surveys and deterioration diagnoses using i-Boat to the development of AI-based technology for assessing residual load-bearing capacity, and the company also received the Japan Port and Airport Research Institute Paper Award. - FY2020AdvancedAnnual report
「During the consolidated fiscal year, the company developed AI technology to automate these detections. It also developed a maintenance and management system that allows users to easily view the progression of deterioration and other information from previously acquired 3D images and deterioration diagnosis results, supporting pier managers in developing their own facility management plans.」
The initiative progressed from pier surveys and deterioration diagnoses using i-Boat to the development of AI-based automated detection of cracks and other defects and a maintenance and management system. - FY2019AdvancedAnnual report
「During the consolidated fiscal year, the company conducted surveys and deterioration diagnoses for privately owned and public piers. It plans to continue actively using the technology for the maintenance and management of port structures.」
The company expanded the use of i-Boat, formerly known as the wireless LAN boat, from surveys and deterioration diagnoses of privately owned piers to public piers as well, broadening its use in actual projects. - FY2018AdvancedAnnual report
「In FY2017, the company received its first order to survey a privately owned pier using a wireless LAN boat and conducted a deterioration diagnosis. It plans to actively use the technology for the maintenance and management of port structures going forward.」
The technology progressed from validation on actual structures using a remote-controlled boat to the first order for a privately owned pier using a wireless LAN boat and the performance of deterioration diagnosis. - FY2017AdvancedAnnual report
「During the consolidated fiscal year, the final year of a 3-year plan, the company used a remote-controlled boat to capture images of the underside of an actual pier, analyzed the images using Structure from Motion/Multi-view Stereo (SfM/MVS) technology, and diagnosed deterioration using dedicated software, confirming that the technology could be used to inspect and diagnose actual structures. Because the work can be performed at more than twice the speed of conventional human-based surveys, it can improve the efficiency of surveys and inspections.」
In the final year of the 3-year plan, the company confirmed the use of the technology to inspect and diagnose actual structures, demonstrating a speed more than twice that of human-based surveys.
