摘要
GB 32167—2015《油气输送管道完整性管理规范》(以下简称GB 32167—2015)虽对高后果区提出了具有普适性的7项风险消减措施,但管控要求较为宽泛,可操作性不强,未专门针对人员密集型高后果区提出管控措施,导致输油管道企业难以量化人员密集型高后果区管控措施。为解决上述问题,对照GB 32167—2015中的7项风险消减措施,制定GB 32167—2015符合性检查表,结合输油管道企业管理实际,优化出针对输油管道人员密集型高后果区的日常管理措施、工程技术措施、应急管理措施3类共计23项可操作性强并便于量化实施的具体管控措施。通过某人员密集型高后果区管控案例实践,采用管道风险矩阵法评估后,案例高后果区风险降级成功。实践证明上述优化措施针对性强,能有效降低输油管道人员密集型高后果区风险,为人员密集型高后果区风险消减和日常管理提供了参考。
Although GB 32167—2015 Code for Integrity Management of Oil and Gas Transmission Pipelines puts forward seven general risk mitigation measures for high consequence areas, the control requirements are relatively broad and not very operable. No control measures are specifically proposed for densely populated high consequence areas, which makes it difficult for oil pipeline companies to quantify the control measures for such areas. In order to solve the above issues, according to the 7 risk mitigation measures in GB 32167—2015 Code for Integrity Management of Oil and Gas Transmission Pipelines, a national standard compliance checklist was developed. Taking into consideration the actual management practices of oil pipeline companies, 23 specific management and control measures, including daily management measures, engineering technical measures and emergency response measures, were optimized for the densely populated high consequence areas of oil pipeline route, which are highly operable and easy to implement in a quantitative manner. Through the actual implementation of management and control measures in a densely populated high consequence area, the risk of the high consequence area was successfully downgraded after the pipeline risk matrix method was used for assessment. The advantages and disadvantages of the above optimization measures are analyzed. The optimization measures are highly targeted to key areas of concern and can effectively lower the risk of the densely populated high consequence area of the oil pipeline route, and provide a reference basis for the risk mitigation and daily management of the densely populated high consequence area.
