Penta-Ocean Construction Co., Ltd. (President: Takuzo Shimizu) won the General Affairs Award for Excellent Utilization of Information and Communication Technology at the 7th Infrastructure Maintenance Awards for its 'Total System for Maintenance and Management of Port Structures Utilizing 3D Image Processing and AI' Received the Minister's Award (technology development category).

The Infrastructure Maintenance Award recognizes outstanding initiatives and technological developments related to infrastructure maintenance in Japan, promotes the efforts of businesses, organizations, researchers, etc. involved in infrastructure maintenance, and aims to revitalize the maintenance industry. The purpose is to spread the philosophy of infrastructure maintenance. The awards ceremony held at the Prime Minister's Office on January 18, 2024 was attended by Director Uno and Section Chief Mizuno of our Technology Research Institute, who were involved in the technology development, and they received a certificate of commendation from Fujino, Deputy Director-General of the Secretariat of the Ministry of Internal Affairs and Communications. Ta.

Because port structures are constructed on the sea, they are subject to significant deterioration due to salt damage.In particular, many typical deterioration conditions caused by salt damage have been confirmed on the underside of the pier superstructure, such as cracks in the concrete, leaching of rust fluid, and peeling and spalling of concrete. Since people usually do not see the underside of the pier, deterioration may progress without you noticing. When an earthquake occurs, such aging piers may be severely damaged and suddenly become unusable. For this reason, it is extremely important to carry out periodic inspections and diagnosis from a BCP perspective and reflect this in the maintenance and renewal of structures.

This system consists of (1) technology that faithfully creates a 3D model of the shape of the target structure from a series of photographs of the concrete underside of the pier superstructure, and (2) technology that automatically extracts and displays cracks and rust stains from the photographic images. ? Technology that uses AI to automatically determine the degree of deterioration of each component in accordance with the 'Guidelines for Inspection and Diagnosis of Port Facilities,' ? How will the concrete of the pier superstructure that has deteriorated be damaged in the event of an earthquake It consists of technology that uses AI to determine whether or not the product will be damaged and where it will be damaged, and displays it on a 3D model and (5) technology that predicts deterioration over time, such as after 5 or 10 years.

This system makes it easy for port managers to understand how damage to a pier will expand in the event of an earthquake, and when to repair or reinforce the pier in order to continue using it. It is possible to contribute to maintenance.

We will continue to strive to contribute to infrastructure maintenance through technological development.
