Abstract:

The formation and handling process of LNG BOG is crucial to the safety and stability of LNG terminal in the long-term operation. If an accident happened during the above-mentioned process, the consequence can be catastrophic. This paper aims to carry out hazard identification for the risk factors in the BOG formation and processing in LNG terminal. Through the combination of on-site investigation and lessons learnt on previous incidents, the risk sources of LNG BOG formation and processing are decided into assessment groups, and the safety risk assessment is undertaken using the Dows Fire and Explosion Index risk assessment method. The results show that the fire and explosion risk level of LNG BOG formation and handling is mostly high and very high. If the design safety and procedure management mitigation measures are adopted, the fire and explosion risk level of each risk group can be effectively reduced to medium and lower level. The results show that the risk of each risk group in the BOG formation and processing of LNG terminal can be lowered by more specific and targeted safety measures and applicable procedure management methods, and optimum application of safety measures and scientific management can also reduce the risk of BOG formation and processing in LNG terminal so as to reduce the occurrence of BOG incidents in LNG terminal and ensure the safety for LNG terminal.
