摘要:

为便于有效实施管道完整性管理,开发了基于C/S网络模式的管道完整性管理系统。系统中构建了管道完整性数据库,管理和维护与管道完整性相关的设计、检测、运行和环境等大量管道数据,采用数据接口技术与外部数据库实现信息共享。以数据库为基础,该系统包括风险评价、腐蚀缺陷和外部腐蚀防护系统评价等基本模块。利用风险评价模块,可以进行管道分段、风险评分、风险决策、风险分析,用腐蚀缺陷评价模块进行内检测缺陷数据统计、剩余强度评价、安全系数曲线绘制和单一缺陷评估,腐蚀防护系统评价模块可根据检测数据计算涂层破损点密度、电流衰减率、绝缘电阻率等分级评价外防腐层和阴极保护系统的有效性。应用本系统对某输油管道进行了完整性评价,评价结果基于实际数据,全面反映了管道的安全状况、风险因素和事故隐患,满足管道全面完整性管理的基本要求。

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.

Key words: oil pipeline, integrity management system, data management, risk assessment, remaining strength, corrosion protection
