Title:
PIPELINE DIAGNOSING DEVICE, ASSET MANAGEMENT DEVICE, PIPELINE DIAGNOSING METHOD, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2019/172455
Kind Code:
A1
Abstract:
This pipeline diagnosing device is provided with a simulation executing unit 11 which, on the basis of pipeline information specifying the configuration of a pipeline facility to be diagnosed, executes a simulation of pressure oscillations in a pipeline in the pipeline facility, a fatigue cycle analyzing unit 12 which calculates a fatigue cycle of the pipeline from the pressure oscillation simulation results and measured data of pressure, and an indicator calculating unit 13 which calculates an indicator representing a failure risk of the pipeline, from the fatigue cycle analyzed by the fatigue cycle analyzing unit 12. In this way, a degree of fatigue progress is obtained and a replacement time for the pipeline is estimated from stresses occurring in the pipeline and the number of times stress fluctuations are repeated.
