Mitsubishi Heavy Industries, Ltd. (MHI) has developed and provided customers with various after-sales maintenance services for equipment maintenance necessary for the stable operation of plant facilities. However, problems such as experienced service technicians and experts retiring are expected to become more serious in the future, so it is necessary to establish a system for providing services that do not depend on human workers. As a measure to address this issue, we have developed a remaining life assessment service of plant piping welds using AI-based image processing. Providing customers with the information necessary for maintenance planning more quickly and accurately than ever before using this service will lead to appropriate equipment maintenance, which in turn will contribute to ensuring the reliability of plant equipment over the medium to long term and the stable supply of electricity.
