Lightning disasters is one of the risk hazards which can not be ignored in the petrochemical industry. Based on the IEC62305 Lightning Risk Assessment, site exploration and lightning protection inspection was carried out at the Fujian LNG Transmission Trunk Line Project Putian LNG Sub transmission Station. The lightning risks mainly lie in the lightning protection devices of the buildings (structures), the pipelines in the process area, the construction quality of the equipment grounding, as well as the lightning electromagnetic pulse problems. Corresponding corrective measures to lightning protection system are put forward. The lightning risk can be controlled below the acceptable value and the personal injury and death can be reduced below the specifications by controlling the quality of lightning protection construction, screening the wiring of the service facilities, reasonable connection layout, equipotential connection, as well as the installation of the surge protective devices with matched parameters at the border line of different lightning protection areas.
