对在役天然气管道压气站进行安全完整性等级（SIL）验证，从结构约束和随机失效两方面评估各安全功能回路的硬件安全完整性，判断其是否达到安全要求，对于未达到要求的功能回路应根据分析从检验测试间隔、设备增加诊断、通道结构、降低失效率等方式提高回路的SIL能力。

Carry out SIL veriifcation to compressor station in natural gas pipeline in service. Take assessment to the hardware safety integrity of safety functions in architecture constraints and random failure, looked whether the safety functions can meet the safety requirement. Improved the SIL of the function through shorten proof test interval, using diagnostic measures, changing channel architecture or reduce failure rate according the assessment if some one can not meet the safety requirement.
