为实现对油气管道风险的有效控制,结合油气管道的特点,基于成本收益分析方法改进风险控制决策过程。首先,确定风险控制目标,对所建议的措施进行初步筛选,并根据行业现状确定基线场景;之后,量化筛选后的措施的成本与收益,通过计算成本收益率(CBR)或规避事故隐含成本(ICAF)来确定相应措施的合理性;最后,依据上述分析制定风险控制决策。结果表明:不同措施的CBR或ICAF值不同,CBR或ICAF值较低的措施应被优先实施;而当CBR或ICAF值超过标准值时,相应措施是不合理的,应不予以实施。
In order to realize the effective control on the risk of oil and gas pipelines, combined with the characteristics of oil and gas pipelines, the risk control decision-making process is improved based on cost-benefit analysis. First, the risk control objectives are determined, the proposed measures are initially screened, and the baseline scenario is determined based on the status quo in the industry; thereafter, the costs and benefits of the screened measures are quantified by calculating the cost-benefit-to-return ratio (CBR) (ICAF) to determine the appropriateness of the corresponding measures; Finally, based on the above analysis to develop risk control decisions. The results show that different measures have different CBR or ICAF values and that CBR or ICAF values should be prioritized. When the CBR or ICAF values exceed the standard values, the corresponding measures are unreasonable and should not be implemented.
