Abstract: Near-miss is a suspended state of accident evolution. A near-miss management solution can be designed to effectively prevent and control accidents. This paper firstly gives the elements to classify and define the near-misses related to long-distance pipeline. Then, for long-distance oil and gas pipeline, the specific near-miss reporting and management procedure and unsafe events Bow-tie analysis results are proposed; according to risk analysis results, safety measures are put forward from two aspects, including controlling safety of pipeline itself and preventing event consequence. Finally, considering the near-miss characters, SQL Sever 2008 and Visual Basic 2010 are adopted to design and develop the nearmiss management system for long-distance oil and gas pipelines. The system is divided into several modules, i.e. user management, information management, pipeline information, and education & training. The study shows that near-miss management is a critical part of risk management system, and it can be strengthened to effectively reduce the risk level and improve efficiency of pipeline risk assessment and emergency response.
