A pipeline integrity management system based on Client/Server mode

Abstract

In order to effectively and conveniently implement pipeline integrity management, a Client/Server-based pipeline integrity management system was developed. The database constructed in the system is able to manage and maintain the mass design, inspection, operation and environment data related to the pipeline integrity. The system can be linked with the external database to share information resources. The management system based on the database can provide such fundamental functions as assessments of risk, corrosion defect and corrosion protection system. The risk assessment module is involved in pipeline segmenting, risk scoring, decision-making and risk analysis. The corrosion defect assessment module conducts the statistic analysis for in-line inspection data, calculation of the residual strength, drawing of safety factor curves and evaluation of a single defect. The corrosion protection assessment module can be used to calculate the damage points density, current attenuation and insulation parameter of the coating according to the inspection data and fractionally evaluate the effectiveness of the coating and cathodic protection. The management system was used to assess the integrity of an oil pipeline using the actual data. The assessed results could reflect the real condition of pipeline safety, risk factors and potential threats overall. This system could meet the fundamental requirement of total pipeline integrity management. Show more
