Title:
CORROSION ESTIMATION METHOD AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/084628
Kind Code:
A1
Abstract:
In a third step S103, the relationship between environment data at underground locations and the magnitude of the corrosion speed in each of a plurality of corrosion samples is derived. In a fourth step S104, a score corresponding to the magnitude of the corrosion speed is set for environment data at the underground locations of each of the plurality of corrosion samples on the basis of the relationship between the environment data and the magnitude of the corrosion speed. In a fifth step S105, the scores set for the environment data are determined as scores of the corresponding plurality of corrosion samples. In a sixth step S106, the risk that a metal structure buried at the underground locations of the plurality of corrosion samples will corrode is estimated on the basis of the scores set through the process described above.
