SECURITY ANALYSIS ON LNG LEAKAGE AND DIFFUSION

The energy supply is in urgent need in the developing China and so the amount of imported LNG is increasing day by day at present. LNG leakage may possibly happen at any times to LNG receiving terminal and those equipments at seaports, the dangers and damages of which should be paid much attention to. Therefore, this paper introduces on LNG importing and the construction of LNG receiving terminal in China. Combing testing and modeling study of LNG leakage and diffusion both home and abroad, it summarizes and analyzes the potential threatening risks on LNG boats cracking, LNG leakage diffusion, fires disaster, and so on, and it discusses the uncertainties of those problems as well. In the end, it puts forward some suggestions on LNG risk evaluation.
