With the rapid expansion of LNG liquefaction plants in developed coastal areas, safety management of explosion-proof electrical equipment is a key to secure development of such new energy enterprises. Due to the lack of systematic guidance on the on-site management of explosion-proof electrical equipment, there are a lot of problems in the risk management of explosion-proof electrical equipment. Based on the on-site inspection results of a new energy company's LNG liquefaction plants of the CNOOC Gas & Power Group, we carried out systematic analysis of different aspects of these results by applying both problem statistics and qualitative methods. In order to reflect the present situation and the ongoing development of explosion-proof electrical equipment, problems are analyzed by dividing equipment full life-cycles into several different stages. This study can be referenced in the full life-cycle risk management of explosion-proof electrical equipment.
