METHOD FOR TECHNICAL MONITORING AND ESTIMATE OF MAIN PIPELINE AND SYSTEM FOR IMPLEMENTATION THEREOF Russian patent published in 2012 - IPC F17D5/00 

FIELD: mechanical engineering.

SUBSTANCE: method involves measuring physical parameters with using a number of gage sensor arranged inside and outside the pipeline along its length, and processing the measured physical values. An estimated mathematical model with reference parameters is pre-created for each i-th pipeline segment. The measured physical parameters and the estimated mathematical model for each i-th segment are used to create a current status adjusted estimated model. The measured physical parameters and the adjusted estimated model for each final model element are used to derive an overall indirect measure of the current status of the pipeline, e.g. a safety factor or safety factor derivatives in a pipeline material. The prepared array of the overall indirect measures is estimated within tolerance areas, namely 'tolerable', 'taking measures required', 'intolerable' to make a decision on the pipeline processing if required. The system for monitoring and estimate comprises a number of gage sensors for measuring the physical parameters and processors of the measured physical parameters. The parameter processors comprise a data collector, a data and estimated model storage unit, an estimated model adjuster, an overall indirect measure calculator, and an operator's workstation data display. Outputs of the gage sensors through the data collector are connected to a first input of the data and estimated model storage unit with its first output connected to a first input of the overall indirect measure calculator and to an input of the estimated model adjuster with its output to a second input of the data and estimated model storage unit with its second output connected to a second input of the overall indirect measure calculator with its output connected to a third input of the data and estimated model storage unit and the operator's workstation data display.

EFFECT: provided trace data presentation that enables the operator making well-timed decisions.
