How to set up safety protection and measures in oil pipeline design?
In response to a recent notice issued by the State Administration of Work Safety and the Development and Reform Commission, which calls for enhanced safety management in urban and rural planning and pipeline engineering design, User Anxy raised important questions about common issues and safety measures in oil pipeline design. To provide clarity, we consulted Chen Jianmin, an expert in oil and gas storage and transportation at Sinopec Xuzhou Pipeline Company.
One major issue identified is that general urban and rural planning often fails to account for long-distance oil and gas pipeline corridors. This lack of foresight results in no clear guidelines or standards to prevent pipelines from being affected by construction activities, leading to a high degree of randomness in planning.
Another challenge lies in the implementation of the "Petroleum and Natural Gas Pipeline Protection Law." While pipelines are typically designed to bypass towns, many older pipelines now run beneath developed areas. As new buildings and structures are constructed around these pipelines, violations of the law occur frequently. However, there is ambiguity regarding who is responsible for enforcement, making it difficult for regulatory authorities to take action. Pipeline companies, lacking law enforcement powers, can only observe these situations without being able to intervene effectively.
In terms of safety protection design, pipeline projects must comply with the "Pipeline Protection Law" and implement various safety measures, such as ground markers, overpressure protection systems, leakage detection systems, SCADA automatic control systems, industrial TV monitoring, cutoff valve rooms, dedicated patrol teams, and emergency maintenance crews. These elements collectively enhance the safety and reliability of pipeline operations.
Several key design specifications guide the construction and management of oil and gas pipelines. These include:
- *Oil Pipeline Engineering Design Specification (2006 Edition) GB 50253-2003*
- *Gas Pipeline Engineering Design Specification GB 50251—2008*
- *Design Specification for Oil and Gas Transmission Pipeline Crossing Engineering GB 50423—2007*
- *Oil and Gas Transmission Pipeline Spanning Engineering Design Specification GB 50459-2009*
- *Technical Specification for Pipeline Trunk Marking Setting SY/T 6064—2011*
- *Specification for Design of Oil and Gas Pipelines SY/T 6853-2012*
- *Code for Design of Hydraulic Protection for Oil and Gas Pipelines SY/T 6793-2010*
- *Safety Regulations for Crude Oil Pipeline Transportation SY/T 5737-2004*
- *Buried Steel Pipeline Risk Assessment Method GB/T 27512-2011*
- *Technical Specification for Oil and Gas Pipeline Safety Early Warning System SY/T 6827-2011*
- *Technical Specifications for Oil and Gas Pipeline Geological Hazard Risk Management SY/T 6828-2011*
- *Oil and Gas Drilling, Development, Storage and Transportation Fire and Explosion Safety Production Technical Regulations SY/T 5225-2012*
These regulations ensure that pipeline design and operation meet strict safety and environmental standards, while also addressing potential risks and hazards throughout the pipeline's lifecycle.
