Lightning protection systems in the natural gas distribution and user systems

This document establishes comprehensive requirements and recommendations for the implementation of lightning protection systems within natural gas distribution networks and user infrastructure located in the Baltic region. It addresses the specific risks associated with high-voltage atmospheric discharges affecting gas pipelines, metering stations, and storage facilities. The text outlines technical criteria for selecting protective equipment, designing earthing arrangements, and ensuring the safe operation of critical components. Detailed procedures are provided for the assessment of lightning hazard potential and the coordination of protection measures with existing electrical systems. Special attention is given to the isolation of potential differences and the prevention of ignition sources triggered by surge currents. The content covers design principles for both new installations and the retrofitting of existing assets to meet current safety expectations. It serves as a technical reference for engineers and safety officers tasked with maintaining the integrity of gas supply chains against atmospheric electromagnetic threats. The guidelines ensure that all protective devices are correctly sized, positioned, and tested to minimize the risk of fire or explosion. Adherence to these specifications helps maintain operational continuity and public safety in gas utility networks.
